Symbolic Logic

Name: Symbolic Logic
Author: Lewis Carroll

The work presents an elementary, diagram-based introduction to symbolic logic, teaching classification, syllogisms, and types of propositions through biliteral and triliteral diagrams and manipulable counters. It explains normal forms for existential and relational statements, offers exercises and examination questions, and adapts puzzles such as the sorites and the Five Liars into symbolized problems. Later parts outline planned advanced and transcendental topics including hypotheticals, multi-literal propositions, theory of inference, and analysis of propositions. Clear definitions, diagrams, worked examples and appended notes aim to make formal reasoning accessible to self-study.

Lewis Carroll

Lewis Carroll, the pen name of Charles Lutwidge Dodgson, was an English writer, mathematician, and logician, best known for his whimsical and imaginative tales. His most famous work, "Alice's Adventures in Wonderland," published in 1865, has captivated readers with its surreal narrative and playful use of language. Carroll's unique blend of fantasy and logic is also evident in his other writings, such as "Through the Looking-Glass" and "A Tangled Tale." Beyond fiction, he contributed to the fields of mathematics and photography, leaving a lasting impact on both literature and academia. His works continue to inspire adaptations and interpretations across various media.
