This book deals with teleology, truth, predication, knowledge and belief, universals, body and mind, soul, and reason. Its approach is integrative, scholastic and analytic. Teleology is required for causality, truth and reason. Where the measure is an end, things measure mind in theoretical truth and mind measures things in practical truth. Truth in Mind draws our reasoning to it as an end. Predication shows how the problem of universals arises and how it is solved. It also impacts the problem of body and mind in that only the hylomorphic assay of persons admits the predicable relations. Reason exemplifies dialectical thought in the syllogism.
