Logic: Deductive and Inductive

This volume offers a clear, systematic introduction to the art of reasoning, distinguishing the ways we prove statements that describe the world around us. It begins by separating quantitative claims—those handled by mathematics—from qualitative ones that appear in everyday conversation, literature, politics, and the natural sciences. Using familiar examples such as “salt dissolves in water” or “ice feels cold,” the author shows how logical tools help us judge truth, falsity, or doubt.

Building on the traditions of Mill, Venn and Keynes, the text weaves together classical syllogisms, the laws of contradiction and causation, and a human‑centered focus on meaning. Revisions and added chapters make the material accessible to modern readers while retaining rigorous analysis. Listeners will come away with a solid grasp of deductive and inductive methods, ready to apply them to both scholarly inquiry and everyday argument.
