Single Idea 8178

[from 'Thought and Reality' by Michael Dummett, in 12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique ]

Full Idea

Our sentences cannot be divided into two classes, empirical and a priori, the truth of one to be decided by observation, the other by ratiocination. They lie on a scale, with observational sentences at one end, and mathematical ones at the other.

Gist of Idea

Empirical and a priori knowledge are not distinct, but are extremes of a sliding scale

A Reaction

The modern post-Kantian dissolution of the rationalist-empiricist debate. I would say that mathematical sentences require no empirical evidence (for their operation, rather than foundation), but a bit of reasoning is involved in observation.
