Single Idea 22291

[catalogued under 5. Theory of Logic / C. Ontology of Logic / 3. If-Thenism]

Full Idea

Deductivism is a good account of large parts of mathematics, but stumbles where mathematics is directly applicable to the world. It fails to explain how we detach the antecedent so as to arrive at unconditional conclusions.

Clarification

'Deductrivism' also known as 'if-thenism'

Gist of Idea

Deductivism can't explain how the world supports unconditional conclusions

A Reaction

I suppose the reply would be that we have designed deductive structures which fit our understanding of reality - so it is all deductive, but selected pragmatically.
