On the basis of careful textual exegesis and philosophical analysis of Aristotle's Metaphysics, Mark R. Wheeler offers a groundbreaking interpretation of Aristotle's theory of truth in terms of measurement. Wheeler demonstrates that Aristotle's investigation of truth and falsehood in the Metaphysics is rigorously methodical, that Aristotle's conceptions of truth contribute to the main lines of thought in the treatise, and that the Metaphysics, taken as a whole, contributes fundamentally to Aristotle's theory of truth. Wheeler provides not only an excellent introduction to the main problems in the theory of truth but also provides contemporary truth theorists with a rigorous explanation of Aristotle's theory of truth.
