John Dewey's Essays in Experimental Logic is a provocative rethinking of how thought, meaning, and knowledge arise from lived experience. With a new introductory essay and a series of revised and expanded studies, Dewey traces the development of ideas, judgments, and objects while asking how logic grows out of action, inquiry, and the practical demands of life. Across discussions of realism, pragmatism, judgment, and the relation between facts and meanings, Dewey argues that ideas are not fixed inner possessions but instruments for investigation and discovery. Symbols, words, and even private mental events gain significance through their representative function, helping inquiry reach non-symbolic reality and avoid dogmatism. He also challenges idealist readings of perception, using familiar examples such as converging railway tracks, delayed starlight, and optical displacement to defend commonsense realism against the claim that appearances prove reality is merely mental. Bold, wide-ranging, and sharply argued, this influential work presents logic as an experimental, evolving process shaped by experience, making it essential reading for anyone interested in philosophy, psychology, and the nature of intelligent inquiry.
