Single Idea 8624

[from 'Grundlagen der Arithmetik (Foundations)' by Gottlob Frege, in 14. Science / C. Induction / 1. Induction ]

Full Idea

Induction depends on the general proposition that the inductive method can establish the truth of a law, or the probability for it. If we deny this, induction becomes nothing more than a psychological phenomenon.

Gist of Idea

Induction is merely psychological, with a principle that it can actually establish laws

A Reaction

The problem is that we can't seem to 'establish' the requisite proposition, even for probability, since probability is in part subjective. I think induction needs the premiss that nature has underlying uniformity, which we then tease out by observation.
