Subject guide

Logic

This Canon Library subject brings together historical works concerned with reasoning, demonstration, language, and the structure of thought. It is a map of influential texts, not a substitute for a modern formal-logic textbook.

A path from accessible to advanced

Begin with a clear philosophical introduction, then compare ancient accounts of argument and explanation with twentieth-century attempts to define the limits of language and formal reasoning.

  1. 1. The Problems of Philosophy

    Bertrand Russell · Moderate · Medium

    The Problems of Philosophy is the most accessible starting point for the questions that motivate analytic philosophy.

  2. 2. Rhetoric

    Aristotle · Challenging · Medium

    Rhetoric broadens the study of reasoning by examining persuasion, evidence, audience, and forms of argument.

  3. 3. Tractatus Logico-Philosophicus

    Ludwig Wittgenstein · Challenging · Medium

    The Tractatus compresses logic, language, and the limits of expression into a demanding numbered structure.

  4. 4. Principia Mathematica

    Bertrand Russell · Moderate · Long

    Principia Mathematica is a specialist landmark in formal foundations and belongs at the advanced end of the sequence.
