Logic, Vol. 2: Demonstrative Inference; Deductive and Inductive (Classic Reprint)

Explore how logic explains how we move from general rules to specific conclusions. This work examines demonstrative induction, deduction, and the extended methods that connect mathematics, science, and everyday reasoning.

With clear analysis and practical examples, it shows how formal principles shape the way we infer, predict, and solve problems. The book outlines the roles of variables, constants, and functional equations, and it contrasts subsumptive and functional deduction to reveal how certain properties are established in mathematics and logic.

• Understand the difference between deduction and demonstration, and how major premisses drive conclusions


• Learn how functional extension expands syllogistic reasoning into scientific domains


• See how symbols, equations, and abstractions are used to model cause and effect


• Explore the limits of induction and the criteria for certitude in reasoning

Ideal for readers of philosophy of science and logic seeking a rigorous, accessible guide to demonstrative inference and its applications.
