As translator H.J. Paton states in his introduction, 'Kant's "Groundwork of the Metaphysic of Morals" is one of the small books which are truly great' despite the unapproachability of the title. Many rank this book alongside Aristotle's 'Ethics' and Plato's 'Republic'. Its main topic is the supremacy of morals and moral action, and Paton gives a section by section analysis of Kant's book. The purpose of this work is not to work out all of the implications and difficulties with the a priori part of ethics, but rather to set a foundation of the supreme principle of morality.

The centerpiece of the Groundwork is Kant's most famous proposition, the Categorical Imperative. While this is often equated with the Golden Rule (do unto others as you would have them do unto you), the Categorical Imperative argues for a more universal set of moral action - for example, if one does not mind being lied to, then lying does not become a problem, according to the Golden Rule, but for Kant, this would be unacceptable as it is a violation of the rational principles of what morals are.

Kant proceeds to look at issues of law, duty, free will and the good will, and autonomy of action. Kant argues strongly for the need for philosophy to guard against whim, taste and personal desire from becoming normative agents in the way we construct the moral universe. He argue for objective principles to govern the will, and categorises these as either hypothetical or categorical. 'All imperatives command either hypothetically or categorically. Hypothetical imperatives declare a possible action to be practically necessary as a means to the attainment of something else that one wills (or that one may will). A categorical imperative would be one which represented an action as objectively necessary in itself apart from its relation to a further end.'

Kant goes from this discussion to the formulation of universal law and the way in which rational agents should formulate and view this kind of law. The final section of this work introduces ideas that will be more fully developed in Kant's 'Critique of Practical Reason', the second of his three-volume Critiques. He also covers some of the arguments from 'Critique of Pure Reason', but not very fully; as Paton states in his analysis, 'Kant cannot assume the elaborate arguments of the "Critique of Pure Reason" to be familiar to his readers nor can he attempt to repeat these elaborate arguments in a short treatise on ethics.' The finite, rational person must regard himself or herself both as a member of the world of experience/perception and also as a member of the world of ideas/rationality. This is the essence of the Empiricist/Rationalist split that Kant synthesises together in the first Critique.

This is not easy going - the original 'Groundwork' had 128 pages, contained here in less than 100 (allowing for type-face differences as well as translation). Paton's version has 40 pages of analysis, endnotes, an index, and a statement about the translation - it is the 40 pages of analysis, keyed to section-by-section sequence, that makes this a very useful edition. This is perhaps the best first text of Kant to read to get a sense of his style, thought, and the foundation of what has become known as his most important principle.

'Groundwork of the Metaphysic of Morals' by Immanuel Kant is easily the most important work devoted exclusively to thinking about morality in the history of Philosophy, especially considering it's size.

The cornerstone of the work, and the end result of Kant's analysis is the categorical imperative which says that a moral law are only those for which you can state should be true of all people.

In one fell swoop, Kant marginalizes all thinking about relativism in morality and at the same time distinguishes moral from religious thinking.

If you pair this up with St. Paul's statements in his letter to the Romans (3:19-28) which states strongly that adherance to the law has virtually nothing to do with salvation, it should make things pretty clear to all concerned.

Unfortunately, things are rarely that simple. As important as Kant's conclusion is, it is necessary but not sufficient for a complete analysis of morality.

One excuse may be that this work is really Kant's version of 'Cliff Notes' to his moral argument. His full presentation comes in the 'Critique of Practical Reason', which, however, is not often read.

Note that contrary to another review of this edition, the translator and commentator is the noted Kant scholar of 70 years ago, H. J. Paton.

To people who are not used to reading philosophy, I will not hide the fact that Kant is tough going. He may not be quite as tough as Hegel, the Existentialists, or the ancient Greeks, but he is definitely harder to understand than any modern nonfiction book I can think of.

The biggest argument against the 'Groundwork' and the categorical imperative is usually the fact that it does not rule out trivial rules, such as 'you must always eat a starch at least once a day'. This rule is physically possible for anyone living anywhere in the world, yet it is certainly not a moral law. It is not even a very good dietary law, but that's neither here nor there. A second argument is that Kant's argument seems a bit circular, when he says that the only thing which unqualifiedly good is a good will.

For anyone who has been vexed by moral questions, an honest reading of this work will at the very least give you hope that with the right amount of thought, one can make sense of moral issues.

A truly great book.

Kant's "Groundwork of the Metaphysics of Morals," despite its forbidding name and demanding content, is perhaps the most eloquent and thought-provoking book on the foundations of rational ethics (or more precisely, moral reasoning) ever published. It certainly is the most influential and revolutionary essay ever about the subject. Unfortunately, it is also one of the most difficult texts of moral philosophy ever written and for this reason lends itself to different interpretations and translations. I recommend relying on the classical translation by H.J. Paton (1964), which comes with a useful "Analysis of the Argument" by the translator (pp. 13-60). In addition, I find B.E.A. Liddell's (1970) modern version of the Grundlegung quite helpful.

Kant begins his argument with these famous words, which immediately get us to the heart of the matter: "It is impossible to conceive anything at all in the world, or even out of it, which can be taken as good without qualification, except a good will.... A good will is not good because of what it effects or accomplishes - because of its fitness for attaining some proposed end; it is good through its willing alone - that is, good in itself." (Paton p. 61f, B1-3)

The crux of the problem of grounding ethics - the core problem of practical reason - consists in the question of how reason can identify and justify an action as "good" (i.e., as the right thing to do). There are only two ways in which this is conceivable, Kant tells us: either, because the action serves to accomplish some other good that is presupposed to be good, or else because this way of acting is good in itself, that is, it has an unconditional quality of being right, in the sense that it may be said to be good under all circumstances. Only this second way can furnish a sufficient foundation for ethics; for anything else would mean to try to ground ethics in mere expediency, that is, in an action's usefulness with a view to some other good. That would not only beg the question of what constitutes good action; it would indeed make ethics redundant. Expediency - instrumental efficacy - serves whatever ends and means we choose, regardless of whether we are guided by a good will. Against such plain relativism, Kant maintains that there must be some less subjective and self-serving form of reasoning about the ends and means of justified action. In my words: "Drop the ego!" is perhaps the most basic intuition underlying all ethics, including rational ethics and its quest for grounding good will in reason. This is how I would basically translate Kant's central concept of "good will" into contemporary terms.

This intuition of holding back the ego (which is not the same as denying it) makes it understandable why classical ethics was preoccupied with psychological and educational questions of character and thus was conceived primarily in terms of virtue ethics. To this preoccupation with character - the classical example is Aristotle's "Nicomachean Ethics," although rational deliberation does play a role in it - the Medieval scholastics later added religion (i.e., faith) as a basis for explaining the binding character of the moral idea, which in effect moved ethics even further away from a grounding in reason. But just as a theological grounding of ethics is helpful only for those who believe, as it presupposes faith without being able to create it, virtue ethics as a methodological (though not as an educational) approach similarly tends to presuppose what it aims to produce: moral character and good will. As a theory of good practice, it ultimately relies on an appeal to the good will (or in Aristotle's framework, to the good character) of agents; for whether or not an agent will in a given situation act virtuously depends on his being goodwilled - an act of faith that cannot be grounded any further but at best be encouraged through education and custom.

Kant's solution to this difficulty is ingenious: he places the origin of a good will within the nature (or concept) of reason itself. To avoid a possible misunderstanding, by reason's nature he does not mean its empirical state or development in the individual but rather, those general structures and requirements which characterize it by inner necessity (a priori), in the sense that reason cannot operate without them ; for example, reason cannot help but regard itself as free (p. 116, B101). In other words, he refers to the nature of pure reason - the sheer idea of reasonableness regardless of its empirical occurrence in individuals. Unlike all previous ethics, including Aristotle, Kant does not assume that the binding force of the moral idea needs to reside in some external psychological or religious condition such as character, faith, or virtuous action. Rather, he understands it as residing in one of the most fundamental conditions of reason itself, the requirement of consequent (or consistent) thought. Living up to its own intrinsic requirements is what Kant calls a "pure" interest of reason or "interest of pure reason" - an interest that has no other aim than preserving the possibility of reason itself.

The implication of this new concept of pure reason is powerful indeed: in its practical no less than in its theoretical employment, reason is itself in charge of the conditions of its successful operation. We can only recognize as true, both in an empirical and in a moral sense, what our mind creates itself; or in the famous words of the Introduction to the second edition of the Critique of Pure Reason (1787, Bxiii): "Reason has insight only into that which it produces after a plan of its own." It is to this shift of perspective that Kant referred as the "Copernican revolution" of speculative philosophy, or as we would rather say today, of epistemology. Copernicus was the first astronomer to recognize very clearly that counter to the observed (phenomenal) movements of the planets around the earth, their true (noumenal) movements were ellipses around the sun. He was able to achieve this revolution of our worldview because he "dared, in a manner contradictory of the senses, but yet true, to seek the observed movements, not in the heavenly bodies, but in the spectator." (1787, Bxxii note). A similar shift of perspective now is to inform Kant's revolution of practical philosophy. Kant himself does not say so - he refers to the Copernican revolution only in his critique of theoretical reason - but I would argue that the notion of a Copernican revolution of ethics provides a very immediate and helpful key to the core of Kant's concept of rational ethics: the reason why we ought to act morally is not because some external authority obliges us but simply because we recognize such action to be reasonable. The moral force resides in our will to be reasonable!

For a moment though, Kant appears to lose sight of this consequence of his own "Copernican" approach when in the last chapter of the Groundwork (p. 123ff, B113ff), we find him searching for some mysterious absolute source of the binding force of the moral idea, a source that would explain why pure reason, before and beyond all empirical motives, is compelled to be moral. Such a force, if it really existed, would need to be independent of all human willing and reasoning and thus external to our mind, if not external to all nature (transcendent) - an implication that runs counter to Kant's core idea of grounding ethics in reason. Lest we fall into this trap of searching for an absolute, transcendent source of morality beyond all human willing and reasoning, I propose we better understand "pure" reason as a mere limiting concept; as an admittedly unreal (nonempirical) ideal-type of reason that serves Kant to undertake his great experiment of thought, the experiment of submitting reason in its practical (moral) no less than in its theoretical (empirical) employment to its own tribunal. Thus seen, Kant's ultimate and vain effort of finding an absolute source of universal moral obligation is a remarkable testimony to his relentless self-critical determination to push his inquiry to its utmost limits, even if such an effort is ultimately bound to fail:

"But how pure reason can be practical in itself without further motives drawn from some other source; that is, how the bare principle of the universal validity of all its maxims ... can by itself ... supply a motive and create an interest which could be called purely moral; or in other words, how pure reason can be practical - all human reason is totally incapable of explaining this, and all the effort and labour to seek such an explanation is wasted." (p. 129, B124f)

But Kant's effort is far from wasted. Without apparently being fully aware of it, he actually uncovers that there is no need at all for such an explanation. The fact that a reasonable agent wants to act morally (i.e., to act out of good will) is quite sufficient for saying he ought to do so; for anything else would undermine the integrity of reason. It belongs to the peculiar force of reason in its "pure" form, that whatever it makes us want, we ought to do. Hence, if as a reasonable being I want to act morally, I ought to do it; and conversely, if reason tells me I ought to do it, as a reasonable being I want it. The moral "ought" is really a call to reason: "'I ought' is properly an 'I will' which holds necessarily for every rational being." (p. 117, B102). This, then, is the core idea of a rational ethics as Kant conceives it: the force of the moral idea resides at bottom in the power of reason, and that must be quite good enough for us as reasonable beings. The moral idea is an immanent rather than a transcendent idea of reason. It is in this sense that it is "necessary" (indispensable) and "categorical" (unconditional) for any rational agent.

We arrive, then, at the most fundamental contribution that Kant has made to practical philosophy, I mean his formalization of the moral idea in terms of the principle of moral universalization or, as he calls it, the categorical imperative: "Act according to a maxim that you could want to become a universal law" (p. 88, B52, and p. 104, B81, my simplified transl.). Or still simpler: "Act only on a premise that can be everyone's premise" (my free transl.).

As is well known, Kant proposes a variety of different formulations of the categorical imperative; but their fundamental concern is the same. It says that to judge the moral quality of an action, we should first ask ourselves what is the underpinning maxim. In Kant's language, a maxim is a subjective rule or norm of action (i.e., in the terms of my simplified translation above, a personal premise), while a principle is an objective, because generally binding or "necessitating" rule or norm of action (i.e., a premise that everyone may be expected to make the basis of their actions). Kant's point in distinguishing the two is that he does not want us to presuppose that our individual premises are naturally in harmony with principles that everyone could hold; quite the contrary, the problem of practical reason emerges from the divergence of the two perspectives (cf. p. 80f, B37-39, and p. 117, B102f). It is because individual and collective premises do not usually converge that Kant asks us to consider what our personal premises are and to what extent they might be the premises of all others concerned. Insofar, the categorical imperative, counter to what is often assumed, cannot be said to be idealistic.

Once we are clear in our mind as to what is the underpinning maxim of an action, the consequent next issue is whether this maxim could hold as a principle of action, in the precise sense just defined. To answer this question, we may assess it against the categorical imperative in its different formulations. If our maxim runs counter to any of these imperatives, it is not an adequate principle, for it cannot be properly universalized. This makes it understandable why Kant calls his three variations "equivalent" despite their apparent differences.

Kant's preferred way of describing the idea of moral universalization is by analogy with "the law." He wavers a bit between the law of the state (legal norms), in the so-called "Formula of Universal Law" (p. 88, B51f), and the law of nature (natural laws) in the "Formula of the Law of Nature" (p. 89, B52). In accordance with the political roots of Kant's concept of reason (see my reviews of Hans Saner's (1973) "Kant's Political Thought" and Onora O'Neill's "Constructions of Reason"), I suggest to take legal norms as the basic metaphor and natural laws as a derived, more illustrative metaphor (for metaphors they are both, just like the concept of "duty" that Kant derives from it and which similarly stands for an unconditional obligation legislated by our own will). As Kant sees it, the principle of moral universalization obligates us not unlike the way a legal norm obligates everyone under its jurisdiction. The difference is that a legal norm obliges us only conditionally, namely, to the extent that we belong to the community of individuals that have given themselves such legislation (and further, to be precise, to the extent that there is no applicable legislation of superior authority that poses different demands). By contrast, a moral norm (or now, for Kant: a "moral law") applies unconditionally or categorically for any rational agent - it is the ultimate source of obligation beyond which we cannot refer to any other, supposedly superior source of obligation.

My own preferred way of thinking of the unconditional moral thrust of the universalization principle is in terms of never treating others merely as a means for one's own ends: "Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means but always at the same time as an end" (the "Formula of the End in Itself," p. 96, B66f). As I tend to translate it for myself: "Do not instrumentalize other people!" or even simpler: "Respect other people!" To be sure, only in combination with the other two Formulas does this imperative of non-instrumentalization fully capture the moral thrust of "universalization"; but for me the notion of non-instrumentalization embodies a humanistic core that comes closest to a truly universal norm of human conduct for our epoch. Furthermore, to overcome any anthropocentric bias one might object against, we may apply it not only to people but equally to animals and all living nature: "Do not instrumentalize other living beings!"

Despite all simplification - a core difficulty remains: We do not and cannot usually act in ways that do justice to everyone. Universalization is an ideal rather than a practical premise. Nor does the universalization principle tell us anything about what our premises should be; necessarily so, as these depend on the situation. Hence, while the suggested reformulations make Kant's intent a bit easier to grasp, they do not tell us how to act accordingly. Kant is therefore often accused of the impractical and abstract, apparently merely formal character of his notion of rational ethics. Yes, it is true, his categorical imperative is not a norm that we can immediately put into practice. But it is the nature of the problem rather than Kant's failure to do justice to it that makes it so difficult. Expecting an immediately practical norm - a recipe for moral action - would be to misunderstand the nature of the problem and worse, it would leave no room for moral reasoning. Moral reasoning is about moral imperfection, not about moral perfection. That is, it is precisely because moral perfection is not usually achievable by human agents that moral reasoning is important. Moral reasoning means to handle the unavoidable moral imperfection of all our claims and actions "with reason," and Kant's "Groundwork" explains what that implies. No other author before and after Kant has thought more thoroughly and rigorously about the problem. And nobody else has arrived at a more fundamental and important conclusion: there exists a deep, inextricable link between morally tenable action and consistent reasoning! This is the great lesson that Kant's practical philosophy can teach us - a lesson that certainly is as pertinent today as it has ever been.

If you would like to read more about this lesson, you may wish to consult the source indicated at the bottom. However, this review is not meant to promote my own writings on practical philosophy, much less to impose my view of the eminent relevance of Kant's practical philosophy for our epoch; rather, it is meant to encourage you to go to the source and read Kant himself. The "Groundwork" probably remains the best place to start exploring this great lesson of which I am talking and which our epoch, it seems to me, has all but forgotten. I would certainly recommend Paton's translation, as in my view it remains the best edition in English language. It is difficult reading, to be sure, but I do not think it is beyond what the so-called general intelligent reader (though perhaps with a dose of not so general perseverance) can handle. For moral reasoning is not and cannot be the privilege of philosophers, certainly not the way Kant understands it. Try it. Read it. Reflect on it. And try again. And if at times you find its language indigestible and its content complicated (rightly so), the above comments and the personal reading they express are meant to put you back on track, by reminding you of the core idea that matters, the deep link between reasonableness and morality. Acting morally, Kant teaches us, means to try and act on principles that we can share with others, by making sure we consider the perspective of those who may be concerned about our ways of acting. Kant's categorical imperative, then, is asking for no more than what every reasonable agent is capable of; but, and this is the difference it makes, it also asks for no less.

I read this book for a graduate seminar on Ethics. In "The Groundwork of the Metaphysics of Morals," Kant astutely observes how ordinary people speak about morality. He argues, ordinary people's views are presupposed about morality, that there is one supreme moral principle it is the "Categorical Imperative" which is discussed in section two of the book. In section one, he talks about value, and special regard or esteem we have for someone who does the right things. Sometimes, people do the right things for wrong reasons. He is interested in what has to be true for an action to have moral worth. He has a kind of criticism of Utilitarians. Utilitarians say you can talk about what is good, i.e., happiness, before talking about what is right or moral. For Kantians "right" comes prior to the question of what is good. One must bring morality in before talking about the good. Talent and ability is good if put to good use, it can also be bad; for example computer hackers creating "viruses." Only one thing is good in and of itself unconditionally, which is a good "will" which means the will of a person who wants to do the right thing. Even if the plan doesn't work out they still have good will. They desire to do the right thing because it is the right thing.

Kant argues that action has moral worth only if it is done out of respect for duty. For example, if a shopkeeper is honest in an effort to look good to customers he did the right thing, but only in "conformity with duty." He acted out of inclination. If the shopkeeper is honest out of being nice or likes kids then his action is still done out of inclination because he "likes to do it," but his moral worth is less in the action. The shopkeeper who has moral worth is the one who is honest because it was the right thing to do.

Kant's 2nd proposition is that an action gets its moral worth from its "maxim." Maxim is a technical term for Kant; maxim is a kind of principle that explains why someone does something. Kant thinks that whenever we act on an action there always is some maxim that we are acting on. So you can think of a maxim as having the form: I will do A (some kind of action) in C (some set of circumstances) for P. (for some purpose). Now it is not as if normally when you act you formulate to yourself here is my maxim, here is what I am acting on. However, Kant thinks that when you do something there is some maxim that describes your choice. Therefore, Kant thinks there is an underlying maxim there, and it is this maxim Kant thinks that is the real decider about whether your action has moral worth or not. Only actions with the right maxim he thinks have moral worth.

Kant's3rd proposition is that duty is the necessity of acting out of respect for law, (not government law). Kant thinks that actions get there moral worth from being done out of respect for a "universal moral law" that is binding on all rational beings. This is the real clincher for Kant in the first section of his book. That actions have moral worth when the person who did the action did it because he or she thought that there is a moral law that commands them to do the action. For example, "I must obey that law, it is necessary; I have no choice but to obey the law." That notion of following the universal moral law is what gives the action, Kant thinks, its worth that is what makes it worthy of the special esteem he thinks we give actions when people have done them just because they thought they were right.

This is the setup for Kant's all important and famous "categorical imperative which he argues applies to everyone. This is all in Section II. We can deduce many rules from the categorical imperative. The categorical imperative is the only one fundamental principle of morality, but it can be formulated in a variety of different ways. Kant had three formulas of the categorical imperative. All three formulas are a different way of wording the categorical imperative. The categorical imperative is a moral law that has to apply to all rational beings, regardless of what ends they have.

The 1st formula is the "Universal Law Formula," which Kant said that every action has a maxim. Whenever you do anything there is some maxim, some subjective principle you are acting on and that we shouldn't act on any maxim that we couldn't choose to become a universal law. Kant then goes on to say that still for every action, in addition to its maxim, there is also an end, every action has an end. Mill and Aristotle also say this. Kant says if you have a categorical imperative there has to be an end that all rational beings see as a good end, this is mandatory. It can't be some kind of effect of our actions, because the kinds of things we produce in the phenomenal world only have value because we care about them. It has to be an end that all rational beings must care about; it can't be a utilitarian end, or one from consequences. If we value it as an end it has value, if we choose it as an end then there is a claim on others to see it as important as well, thus, this is a real mandatory end that humanity itself sees. Rational nature itself then has value.

The 2nd formula is "The Formula of Humanity" which states, I'm not just special because everyone thinks they are valuable. Can't treat other people as merely a means to an end. This gives one a claim to the help from other people. Slavery is an epitome of this formula as an example. It is wrong to treat people ONLY as a means to an end. (However, you are not using a grocery bagger as such because he gets paid). When you put the Universal Law Formula and Formula of Humanity together, you get another way of formulating the Categorical Imperative.

The 3rd Formula is "The Kingdom of Ends Formula." We ought to be thinking of ourselves as legislators for a kingdom of people who are ends to themselves and for Kant that is what we are doing when we are acting morally. We should only act on maxims that can be laws for a community (Kingdom) of rational beings. Thus, we are both subjects and sovereigns in this community, because we make our own laws and then we must obey them. This is the reason Kant thinks that the categorical imperative is binding on all of us because we impose it on ourselves and make the laws, not binding just because somebody might punish us if we disobey. We already accept the categorical imperative according to Kant without thinking about it. We end up with the ideas of autonomy and motivation. We end up with the idea that reason alone must be capable of motivating us to act a certain way which for Kant means we have autonomy (self rule), (motivated by reason as opposed to desires), which gives us free will. We can only be bound by moral laws if we have this kind of autonomy, if we are motivated by reason, if we have in a sense a free will. Kant thinks it goes in the other direction as well, if we have a free will then we are bound by the categorical imperative.

Thus, philosophers ask do we truly have free will? Also, to what extent are we moved by causation? Kant says laws govern causation. One type of law is Newton's laws of motion, scientific laws. Philosophers debate the question is human actions like these laws? Can we predict human actions? Do our desires cause us to act in certain ways; can our actions be predetermined? Some say yes. Aristotle calls this "efficient causation." Some call them "laws of natural necessity." Given the way the natural world works, things have to happen in a certain way and the world is governed by certain laws.

Kant says if we have a free will, then the laws that govern our choices are not going to be laws of natural necessity. If we have a free will, then our will or our practical reason will choose its own principles, its own laws to act on, and those will be the laws that will cause us to do certain things. If we have a free will, then our will chooses certain principles these must have form of a law for everyone; a universal law, this is the categorical imperative. Thus, for Kant, if we have free will then the categorical imperative is binding on us.

I recommend you read this work slowly and repeat key passages for better comprehension. Kant's work is a must for anyone interested in philosophy, and ethics.

Kant then goes on to say that still for every action, in addition to its maxim, there is also an end, every action has an end. Mill and Aristotle also say this. Kant says if you have a categorical imperative there has to be an end that all rational beings see as a good end, this is mandatory. It can't be some kind of effect of our actions, because the kinds of things we produce in the phenomenal world only have value because we care about them. It has to be an end that all rational beings must care about; it can't be a utilitarian end, or one from consequences. If we value it as an end it has value, if we choose it as an end then there is a claim on others to see it as important as well, thus, this is a real mandatory end that humanity itself sees. Rational nature itself then has value.

The 2nd formula is "The Formula of Humanity" which states, I'm not just special because everyone thinks they are valuable. Can't treat other people as merely a means to an end. This gives one a claim to the help from other people. Slavery is an epitome of this formula as an example. It is wrong to treat people ONLY as a means to an end. (However, you are not using a grocery bagger as such because he gets paid). When you put the Universal Law Formula and Formula of Humanity together, you get another way of formulating the Categorical Imperative.

The 3rd Formula is "The Kingdom of Ends Formula." We ought to be thinking of ourselves as legislators for a kingdom of people who are ends to themselves and for Kant that is what we are doing when we are acting morally. We should only act on maxims that can be laws for a community (Kingdom) of rational beings. Thus, we are both subjects and sovereigns in this community, because we make our own laws and then we must obey them. This is the reason Kant thinks that the categorical imperative is binding on all of us because we impose it on ourselves and make the laws, not binding just because somebody might punish us if we disobey. We already accept the categorical imperative according to Kant without thinking about it. We end up with the ideas of autonomy and motivation. We end up with the idea that reason alone must be capable of motivating us to act a certain way which for Kant means we have autonomy (self rule), (motivated by reason as opposed to desires), which gives us free will. We can only be bound by moral laws if we have this kind of autonomy, if we are motivated by reason, if we have in a sense a free will. Kant thinks it goes in the other direction as well, if we have a free will then we are bound by the categorical imperative.

Thus, philosophers ask do we truly have free will? Also, to what extent are we moved by causation? Kant says laws govern causation. One type of law is Newton's laws of motion, scientific laws. Philosophers debate the question is human actions like these laws? Can we predict human actions? Do our desires cause us to act in certain ways; can our actions be predetermined? Some say yes. Aristotle calls this "efficient causation." Some call them "laws of natural necessity." Given the way the natural world works, things have to happen in a certain way and the world is governed by certain laws.

Kant says if we have a free will, then the laws that govern our choices are not going to be laws of natural necessity. If we have a free will, then our will or our practical reason will choose its own principles, its own laws to act on, and those will be the laws that will cause us to do certain things. If we have a free will, then our will chooses certain principles these must have form of a law for everyone; a universal law, this is the categorical imperative. Thus, for Kant, if we have free will then the categorical imperative is binding on us.

I recommend you read this work slowly and repeat key passages for better comprehension. Kant's work is a must for anyone interested in philosophy, and ethics.

I read this book for a graduate seminar on Ethics. In "The Groundwork of the Metaphysics of Morals," Kant astutely observes how ordinary people speak about morality. He argues, ordinary people's views are presupposed about morality, that there is one supreme moral principle it is the "Categorical Imperative" which is discussed in section two of the book. In section one, he talks about value, and special regard or esteem we have for someone who does the right things. Sometimes, people do the right things for wrong reasons. He is interested in what has to be true for an action to have moral worth. He has a kind of criticism of Utilitarians. Utilitarians say you can talk about what is good, i.e., happiness, before talking about what is right or moral. For Kantians "right" comes prior to the question of what is good. One must bring morality in before talking about the good. Talent and ability is good if put to good use, it can also be bad; for example computer hackers creating "viruses." Only one thing is good in and of itself unconditionally, which is a good "will" which means the will of a person who wants to do the right thing. Even if the plan doesn't work out they still have good will. They desire to do the right thing because it is the right thing.

Kant argues that action has moral worth only if it is done out of respect for duty. For example, if a shopkeeper is honest in an effort to look good to customers he did the right thing, but only in "conformity with duty." He acted out of inclination. If the shopkeeper is honest out of being nice or likes kids then his action is still done out of inclination because he "likes to do it," but his moral worth is less in the action. The shopkeeper who has moral worth is the one who is honest because it was the right thing to do.

Kant's 2nd proposition is that an action gets its moral worth from its "maxim." Maxim is a technical term for Kant; maxim is a kind of principle that explains why someone does something. Kant thinks that whenever we act on an action there always is some maxim that we are acting on. So you can think of a maxim as having the form: I will do A (some kind of action) in C (some set of circumstances) for P. (for some purpose). Now it is not as if normally when you act you formulate to yourself here is my maxim, here is what I am acting on. However, Kant thinks that when you do something there is some maxim that describes your choice. Therefore, Kant thinks there is an underlying maxim there, and it is this maxim Kant thinks that is the real decider about whether your action has moral worth or not. Only actions with the right maxim he thinks have moral worth.

Kant's3rd proposition is that duty is the necessity of acting out of respect for law, (not government law). Kant thinks that actions get there moral worth from being done out of respect for a "universal moral law" that is binding on all rational beings. This is the real clincher for Kant in the first section of his book. That actions have moral worth when the person who did the action did it because he or she thought that there is a moral law that commands them to do the action. For example, "I must obey that law, it is necessary; I have no choice but to obey the law." That notion of following the universal moral law is what gives the action, Kant thinks, its worth that is what makes it worthy of the special esteem he thinks we give actions when people have done them just because they thought they were right.

This is the setup for Kant's all important and famous "categorical imperative which he argues applies to everyone. This is all in Section II. We can deduce many rules from the categorical imperative. The categorical imperative is the only one fundamental principle of morality, but it can be formulated in a variety of different ways. Kant had three formulas of the categorical imperative. All three formulas are a different way of wording the categorical imperative. The categorical imperative is a moral law that has to apply to all rational beings, regardless of what ends they have.

The 1st formula is the "Universal Law Formula," which Kant said that every action has a maxim.

Thus, philosophers ask do we truly have free will? Also, to what extent are we moved by causation? Kant says laws govern causation. One type of law is Newton's laws of motion, scientific laws. Philosophers debate the question is human actions like these laws? Can we predict human actions? Do our desires cause us to act in certain ways; can our actions be predetermined? Some say yes. Aristotle calls this "efficient causation." Some call them "laws of natural necessity." Given the way the natural world works, things have to happen in a certain way and the world is governed by certain laws.

Kant says if we have a free will, then the laws that govern our choices are not going to be laws of natural necessity. If we have a free will, then our will or our practical reason will choose its own principles, its own laws to act on, and those will be the laws that will cause us to do certain things. If we have a free will, then our will chooses certain principles these must have form of a law for everyone; a universal law, this is the categorical imperative. Thus, for Kant, if we have free will then the categorical imperative is binding on us.

I recommend you read this work slowly and repeat key passages for better comprehension. Kant's work is a must for anyone interested in philosophy, and ethics.

I read this book for a graduate seminar on Ethics. In "The Groundwork of the Metaphysics of Morals," Kant astutely observes how ordinary people speak about morality. He argues, ordinary people's views are presupposed about morality, that there is one supreme moral principle it is the "Categorical Imperative" which is discussed in section two of the book. In section one, he talks about value, and special regard or esteem we have for someone who does the right things. Sometimes, people do the right things for wrong reasons. He is interested in what has to be true for an action to have moral worth. He has a kind of criticism of Utilitarians. Utilitarians say you can talk about what is good, i.e., happiness, before talking about what is right or moral. For Kantians "right" comes prior to the question of what is good. One must bring morality in before talking about the good. Talent and ability is good if put to good use, it can also be bad; for example computer hackers creating "viruses." Only one thing is good in and of itself unconditionally, which is a good "will" which means the will of a person who wants to do the right thing. Even if the plan doesn't work out they still have good will. They desire to do the right thing because it is the right thing.

Kant argues that action has moral worth only if it is done out of respect for duty. For example, if a shopkeeper is honest in an effort to look good to customers he did the right thing, but only in "conformity with duty." He acted out of inclination. If the shopkeeper is honest out of being nice or likes kids then his action is still done out of inclination because he "likes to do it," but his moral worth is less in the action. The shopkeeper who has moral worth is the one who is honest because it was the right thing to do.

Kant's 2nd proposition is that an action gets its moral worth from its "maxim." Maxim is a technical term for Kant; maxim is a kind of principle that explains why someone does something. Kant thinks that whenever we act on an action there always is some maxim that we are acting on. So you can think of a maxim as having the form: I will do A (some kind of action) in C (some set of circumstances) for P. (for some purpose). Now it is not as if normally when you act you formulate to yourself here is my maxim, here is what I am acting on. However, Kant thinks that when you do something there is some maxim that describes your choice. Therefore, Kant thinks there is an underlying maxim there, and it is this maxim Kant thinks that is the real decider about whether your action has moral worth or not. Only actions with the right maxim he thinks have moral worth.

Kant's3rd proposition is that duty is the necessity of acting out of respect for law, (not government law). Kant thinks that actions get there moral worth from being done out of respect for a "universal moral law" that is binding on all rational beings. This is the real clincher for Kant in the first section of his book. That actions have moral worth when the person who did the action did it because he or she thought that there is a moral law that commands them to do the action. For example, "I must obey that law, it is necessary; I have no choice but to obey the law." That notion of following the universal moral law is what gives the action, Kant thinks, its worth that is what makes it worthy of the special esteem he thinks we give actions when people have done them just because they thought they were right.

This is the setup for Kant's all important and famous "categorical imperative which he argues applies to everyone. This is all in Section II. We can deduce many rules from the categorical imperative. The categorical imperative is the only one fundamental principle of morality, but it can be formulated in a variety of different ways. Kant had three formulas of the categorical imperative. All three formulas are a different way of wording the categorical imperative. The categorical imperative is a moral law that has to apply to all rational beings, regardless of what ends they have.

The 1st formula is the "Universal Law Formula," which Kant said that every action has a maxim. Whenever you do anything there is some maxim, some subjective principle you are acting on and that we shouldn't act on any maxim that we couldn't choose to become a universal law. Kant then goes on to say that still for every action, in addition to its maxim, there is also an end, every action has an end. Mill and Aristotle also say this. Kant says if you have a categorical imperative there has to be an end that all rational beings see as a good end, this is mandatory. It can't be some kind of effect of our actions, because the kinds of things we produce in the phenomenal world only have value because we care about them. It has to be an end that all rational beings must care about; it can't be a utilitarian end, or one from consequences. If we value it as an end it has value, if we choose it as an end then there is a claim on others to see it as important as well, thus, this is a real mandatory end that humanity itself sees. Rational nature itself then has value.

The 2nd formula is "The Formula of Humanity" which states, I'm not just special because everyone thinks they are valuable. Can't treat other people as merely a means to an end. This gives one a claim to the help from other people. Slavery is an epitome of this formula as an example. It is wrong to treat people ONLY as a means to an end. (However, you are not using a grocery bagger as such because he gets paid). When you put the Universal Law Formula and Formula of Humanity together, you get another way of formulating the Categorical Imperative.

The 3rd Formula is "The Kingdom of Ends Formula." We ought to be thinking of ourselves as legislators for a kingdom of people who are ends to themselves and for Kant that is what we are doing when we are acting morally. We should only act on maxims that can be laws for a community (Kingdom) of rational beings. Thus, we are both subjects and sovereigns in this community, because we make our own laws and then we must obey them. This is the reason Kant thinks that the categorical imperative is binding on all of us because we impose it on ourselves and make the laws, not binding just because somebody might punish us if we disobey. We already accept the categorical imperative according to Kant without thinking about it. We end up with the ideas of autonomy and motivation. We end up with the idea that reason alone must be capable of motivating us to act a certain way which for Kant means we have autonomy (self rule), (motivated by reason as opposed to desires), which gives us free will. We can only be bound by moral laws if we have this kind of autonomy, if we are motivated by reason, if we have in a sense a free will. Kant thinks it goes in the other direction as well, if we have a free will then we are bound by the categorical imperative.

Thus, philosophers ask do we truly have free will? Also, to what extent are we moved by causation? Kant says laws govern causation. One type of law is Newton's laws of motion, scientific laws. Philosophers debate the question is human actions like these laws? Can we predict human actions? Do our desires cause us to act in certain ways; can our actions be predetermined? Some say yes. Aristotle calls this "efficient causation." Some call them "laws of natural necessity." Given the way the natural world works, things have to happen in a certain way and the world is governed by certain laws.

Kant says if we have a free will, then the laws that govern our choices are not going to be laws of natural necessity. If we have a free will, then our will or our practical reason will choose its own principles, its own laws to act on, and those will be the laws that will cause us to do certain things. If we have a free will, then our will chooses certain principles these must have form of a law for everyone; a universal law, this is the categorical imperative. Thus, for Kant, if we have free will then the categorical imperative is binding on us.
