This is a book about Aristotle's philosophy of language, interpreted in a framework that provides a comprehensive interpretation of Aristotle's metaphysics, philosophy of mind, epistemology and science. The aims of the book are to explicate the description of meaning contained in De Interpretatione and to show the relevance of that theory of meaning to much of the rest of Arisotle's philosophy. In the process Deborah Modrak reveals how that theory of meaning has been much maligned.
