John Dewey - Logic and Method

Logic and Method

Dewey sees paradox in contemporary logical theory. Proximate subject matter garners general agreement and advance, while the ultimate subject matter of logic generates unremitting controversy. In other words, he challenges confident logicians to answer the question of the truth of logical operators. Do they function merely as abstractions (e.g., pure mathematics) or do they connect in some essential way with their objects, and therefore alter or bring them to light?

Logical positivism also figured in Dewey's thought. About the movement he wrote that it "eschews the use of 'propositions' and 'terms', substituting 'sentences' and 'words'." ("General Theory of Propositions", in Logic: The Theory of Inquiry) He welcomes this changing of referents "in as far as it fixes attention upon the symbolic structure and content of propositions." However, he registers a small complaint against the use of "sentence" and "words" in that without careful interpretation the act or process of transposition "narrows unduly the scope of symbols and language, since it is not customary to treat gestures and diagrams (maps, blueprints, etc.) as words or sentences." In other words, sentences and words, considered in isolation, do not disclose intent, which may be inferred or "adjudged only by means of context."

Yet Dewey was not entirely opposed to modern logical trends. Concerning traditional logic, he states:

"Aristotelian logic, which still passes current nominally, is a logic based upon the idea that qualitative objects are existential in the fullest sense. To retain logical principles based on this conception along with the acceptance of theories of existence and knowledge based on an opposite conception is not, to say the least, conductive to clearness – a consideration that has a good deal to do with existing dualism between traditional and the newer relational logics. —(Qualitative Thought 1930)

Louis Menand argues in The Metaphysical Club that Jane Addams had been critical of Dewey's emphasis on antagonism in the context of a discussion of the Pullman strike of 1894. In a later letter to his wife, Dewey confessed that Addams' argument was

"the most magnificent exhibition of intellectual & moral faith I ever saw. She converted me internally, but not really, I fear.... When you think that Miss Addams does not think this as a philosophy, but believes it in all her senses & muscles-- Great God... I guess I'll have to give it up & start over again."

He went on to add,

"I can see that I have always been interpreting dialectic wrong end up, the unity as the reconciliation of opposites, instead of the opposites as the unity in its growth, and thus translated the physical tension into a moral thing... I don't know as I give the reality of this at all,... it seems so natural & commonplace now, but I never had anything take hold of me so."

In a letter to Addams herself, Dewey wrote, clearly influenced by his conversation with her:

"Not only is actual antagonizing bad, but the assumption that there is or may be antagonism is bad-- in fact, the real first antagonism always comes back to the assumption."
