Excerpt from The Psychological Review, Vol. 13<br><br>The treatise on the Categories, which discusses the nature of the most general terms, forms a connecting link between logic and metaphysics. The categories are the most general concepts or universal modes under which we have knowledge of the world. They are not Simply logical relations; they are ex istential forms, being not only the modes under which thought regards being, but the modes under which being exists. Aris totle's theory of the methodology of science is intimately con nected with his View of knowledge. Scientific knowledge in his Opinion refers to the essence of things; for example, to those universal aspects of reality which are given in particulars, but which remain self-identical amidst the variation and passing of particulars. The universal, however, is known only through and after particulars. There is no such thing as innate knowl edge or Platonic reminiscence. Knowledge, if not entirely em pirical, has its basis in empirical reality. Causes are known only through effects. The universals have no existence apart from things, although they exist realz'ter in things. Empirical knowledge of particulars must, therefore, precede in time the conceptual or scientific knowledge of universals. In the evo lution of scientific knowledge in the individual mind, the body of particulars or of sense experience is to its conceptual trans formation as potentiality is to actuality, matter to form, the completed end of the former being realized in the latter. Only in the sense of this power to transform and conceptualize, does the mind have knowledge within itself. The genetic content is experiential; the developed concept, judgment, or inference is inform noetic. Knowledge is, therefore, not a mere precipi tate of experience,' nor is Aristotle a complete empiricist.<br><br>About the Publisher<br><br>Forgotten Books publishes hundreds of thousands of rare and classic books.
