In the fourth book, Book Gamma, of his Metaphysics, Aristotle treats the nature and range of science, outlines an approach to ontology, formulates and defends first principles, articulates an influential conception of truth, and defends his views against his relativist contemporaries. In The Gamma Paradoxes, Jeremy Kirby analyzes Book Gamma and introduces debates-or paradoxes-such as relativism versus the idea of a ready-made world, the possibility of true contradictions, the nature and possibility of metaphysics, and the limits of thought and logic. These paradoxes raise issues of contemporary interest: that which may be known a priori; the relationship between mind, language, and world; and, inter alia, the values of logic. Book Gamma is the mise-en-scène for Aristotle's investigation into the perennial question, the nature of substance, and the denouement, as unmoved mover. Book jacket.
