The Science of Logic, Vol. 2 of 2: An Inquiry Into the Principles of Accurate Thought and Scientific Method (Classic Reprint)

This edition focuses on how to turn clear thinking into reliable knowledge. It explains the roles of observation, hypothesis, and method in pursuing truth. You’ll see how engineers of thought separate what is self-evident from what must be demonstrated, and how induction, deduction, and analysis work together in science and philosophy.

Readers will encounter practical discussions of how scientists test ideas, verify hypotheses, and measure evidence. The text also surveys the limits of explanation and the conditions for certitude in different kinds of knowledge.

• Clear explanations of self-evident principles, induction, and demonstration.


• How to combine agreement and difference to identify causal factors.


• Guidance on observation, experiment, and the role of evidence in reasoning.


• Discussion of science, certainty, and the pursuit of universal judgments.

Ideal for readers seeking a rigorous, historical, and method-focused view of logic's role in knowledge.
