[filed under theme 5. Theory of Logic / E. Structures of Logic / 1. Logical Form ]

Full Idea

The logical form of the statement must already be given in the forms of its constituents.

Gist of Idea

A statement's logical form derives entirely from its constituents

Source

Ludwig Wittgenstein (Notebooks 1914-1916 [1915], 23e)

Book Ref

Wittgenstein,Ludwig: 'Notebooks 1914-1916 (2nd ed)' [Blackwell 1979], p.23


A Reaction

This would evidently require each constituent to have a 'logical form'. It is hard to see what that could beyond its part of speech. Do two common nouns have the same logical form?
