Editorial Reviews


"an epochal work ... Parfit's intellectual personality radiates throughout On What Matters, which as a whole presents a gripping and illuminating picture of a single, comprehensive view of the projects of both normative and metaethical inquiry." --Mark Schroeder, Notre Dame Philosophical Reviews

"the most significant work in ethics since Sidgwick's masterpiece was published in 1873 ... a work of epic proportions and ambitions." --Peter Singer, Times Literary Supplement

"Parfit's intricate and beautifully lucid book is undoubtedly the work of a philosophical genius." --John Cottingham, The Tablet

Format: Hardcover
Most professional philosophers regard Derek Parfit as the greatest living moral philosopher. For most the past quarter of a century, Parfit has devoted his formidable philosophical abilities to developing the arguments for the two main claims of his new epic two-volume work. The first of these claims is that the three major traditions in ethical theory - Kantianism, Contractualism, and Consequentialism - ultimately converge. If this is true, much of what we have assumed to be deep and intractable moral disagreement is actually merely superficial, or merely apparent. The second claim is that there are moral truths that are irreducibly normative - that is, not mere expressions of emotions or attitudes, not reducible to natural facts, but not supernatural in origin either. These are conclusions that we have reason to hope are true. And there is a great deal more in these two volumes than just the rigorous arguments for these conclusions. Two major moral philosophers - Peter Singer and Brad Hooker - have both written in published reviews that On What Matters is the most important work in moral philosophy since Henry Sidgwick's Methods of Ethics, which was published in 1873. But that may be too modest, for it is arguable that Parfit has surpassed even Sidgwick. No one who is seriously interested in ethics can afford to not to read these two magisterial volumes.

Sorry, this is not a review, just an alert that what you get as of June 27, 2011, is volume TWO, and not volume One as indicated. I reported the problem, and I hope it will be corrected. Before you buy the kindle edition labeled as Volume I, just get the sample first and check to make sure that the mix up has been corrected, unless you want to start with Volume TWO, which also includes some comments for Volume ONE.

Format: Hardcover
I think Parfit presents his ethical views with amazing ingenuity and nearly-robotic clarity, but passionate determination too. In the second half of the book, he argues that we can unify the most plausible versions of three major ethical theories: Kantianism, Social Contract Theory, and Consequentialism. According to his "Triple Theory", we should follow the set of principles that everyone could rationally will to be accepted universally, because such acceptance would make things go best. (p. 413)

In the first half of the book, Parfit tenaciously advances his theory of Objectivism about reasons. This view says facts can give you reasons to act, desire and believe things, regardless of what you may want. Here are two examples: 1) If you can save a bleeding stranger's life just by calling an ambulance, then that fact gives you a reason to do it, even if you'd rather not. 2) Everyone has a decisive reason to avoid agony.

Subjectivists must deny such intuitive claims. On their view, you have a reason to do something just in case you want to, or would want to after careful, informed deliberation. Besides having counterintuitive implications, Parfit argues, Subjectivism is groundless. If our desires are not fundamentally supported by some reason(s), then they are merely arbitrary. Arbitrary desires could not then give us reasons to do things. "So Subjective theories are built on sand," he concludes. (p. 91)

I think Parfit makes many important refinements of Kant's views on respect, consent, desert and the Golden Rule. To my surprise, he seems to show that it's not always wrong to use someone merely as a means to your own ends, and harm him without his consent!

Format: Hardcover
"What is good and what is not good? Do we need anyone to tell us these things?"

It's a pattern as old as Socrates: pick a nice, empty rhetorical container on which there is some vaguely general agreement--"Good" or "True" or, in Parfit's case, "Reason(s)"--then fill it with whatever you want. It cannot be denied that Parfit has constructed a meticulous rhetorical edifice, a recitation of definitions to rival Webster, but the sum total of his contribution appears to be the claim that deontology, consequentialism, and contractualism should all yield the same ethical results (even though, as presently understood by their various proponents, they don't). All of this is founded on a notion of "reasons" that sometimes succeeds and sometimes fails, at least to the extent that an ordinary-language descriptive-ethics is what Parfit intends. Kudos to Parfit for constructing a work as labyrinthine as anything Kant ever penned; simply attempting to decipher some of Parfit's claims should give philosophy professors something to argue about at great length and for years to come (indeed, some such arguments are already included in Volume 2!). So good news, I suppose, if you're in need of a thesis, but do not expect anything approaching conceptual clarity to arise from this mess.

Somewhat more particularly, I felt that Parfit's most egregious mistake was classifying virtue ethics, without comment, as a sub-category of consequentialism (it's not). He completely ignores some of the most interesting ordinary-language ethics to come out of academic philosophy in the last thirty years.
