Single Idea 15033

[from 'Writing the Book of the World' by Theodore Sider, in 10. Modality / C. Sources of Modality / 4. Necessity from Concepts ]

Why are logical (or mathematical, or analytic...) truths necessary? The Humean's answer is that this is just how our concept of necessity works.

Gist of Idea

Humeans says mathematics and logic are necessary because that is how our concept of necessity works

A Reaction

This is why I (unlike Sider) am not a Humean. If we agreed that 'necessary' meant 'whatever is decreed by the Pope', that would so obviously not be necessary that we would have to start searching nature for true necessities.
