All mental activities-thinking, remembering, judging, anticipating, planning, and conceptualizing-involve two distinctively different components: (1) a sense of knowing, or a sense of having experienced previously, and (2) a cognitive content, or what it is that we know, think, remember, or plan. Each thought, memory, or idea has its own specific content that remains fairly constant when reproduced in our minds. Ample evidence implies that the cognitive content of any mental experience or activity is determined by the patter-or gestalt-of images within the mind, which stem from specific brain functions. In contrast, there exists no imaginable primary brain function that suggests a cerebral origin of our sense of knowing. It is inconceivable, however, that we could experience a sense of knowing without cognitive content and vice versa. Therefore, van der Velde concludes, our sense of knowing is inseparably associates with our experience of cognitive content.
The author proposes that our sense of cognition may evolve as a consequence of our experiencing cognitive content and thus is an empirical-or purely experiential-product. According to this scenario, our capacity for cognition springs from an inextricable combination of a cerebral process responsible for the activation of the mind's images whose gestalts cause us to experience cognitive content and an empirical process that emanates from this cerebral experience and, in turn, imparts its content as an empirical quality of having experienced before. In other words, our sense of knowing is an empirical epiphenomenon that arises from our experiencing cerebrally produced internal images.
Is there such an empirical process that causes us to experience our internal images with a sense of knowing? According to can der Velde, we continually develop groups of two notions that reflect sets of two opposing events-one event is caused by a given quality whose absence causes the occurrence of its opposite. Yet we conceive these events as interconnected because we cannot realize one event without realizing the other-for example, our notions of day and night. As can der Velde explains in chapter 2, these inseparable ideas are called dialectical notions, and their underlying events dialectical events.
THE MIND explores the relationship between the brain and the mind, drawing on current medical and psychological research. Can der Velde's cerebral-empirical rationale of our capacity for cognition offers a valuable new approach to our understanding of the origin and nature of our mental experiences.
