Full Idea

Recent commentators have noted that Frege's versions of the basic propositions of arithmetic can be derived from Hume's Principle alone, that the fatal Law V is only needed to derive Hume's Principle itself from the definition of number.

Gist of Idea

We can get arithmetic directly from HP; Law V was used to get HP from the definition of number

A Reaction

Crispin Wright is the famous exponent of this modern view. Apparently Charles Parsons (1965) first floated the idea.
