Single Idea 8752

[from 'Thinking About Mathematics' by Stewart Shapiro, in 6. Mathematics / C. Sources of Mathematics / 7. Formalism ]

Full Idea

The Deductivist version of formalism (sometimes called 'if-thenism') says that the practice of mathematics consists of determining logical consequences of otherwise uninterpreted axioms.

Gist of Idea

Deductivism says mathematics is logical consequences of uninterpreted axioms

Source

Stewart Shapiro (Thinking About Mathematics [2000], 6.2)

Book Reference

A Reaction

[Hilbert is the source] More plausible than Term or Game Formalism (qv). It still leaves the question of why it seems applicable to nature, and why those particular axioms might be chosen. In some sense, though, it is obviously right.
