Full Idea
We construct a hypothesis on the basis of an induction, that is on the basis of a comparison of experiences.

Hypotheses come from induction, which is comparison of experiences

A Reaction
This fits the traditional positivist picture of science (observe-hypothesise-predict-observe). I like the definition of induction as 'comparison of experiences', because it doesn't reduce it to sequences of objects, and points to coherence.
