This book is a consideration of the differences between Aristotelian and symbolic logic (and the metaphysical assumptions they come packaged with) and the consequences these have for how we view the world. What Veatch propose is to try to exhibit with respect to several of the key logical tools and devices – propositions, inductive and deductive arguments, scientific and historical explanations, definitions, etc. – how these several instruments are differently conceived, both as to their natures and their functions, in each of these respective logics.
