Single Idea 17445

[filed under theme 7. Existence / C. Structure of Existence / 4. Ontological Dependence ]

Full Idea

Frege says that parallelism is more fundamental than sameness of direction because all geometrical notions must originally be given in intuition.

Gist of Idea

Parallelism is intuitive, so it is more fundamental than sameness of direction

A Reaction

If Frege thinks some truths are more fundamental, this gives an indication of his reasons. But intuition is not a very strong base.
