Single Idea 24138

[filed under theme 12. Knowledge Sources / A. A Priori Knowledge / 11. Denying the A Priori ]

Full Idea

What we believe the most, everything a priori, is not for that reason more certain, just because it is so strongly believed. Rather, it is perhaps a consequence of the condition for the existence of our species.

Gist of Idea

Strongly believed a priori is not certain; it may just be a feature of our existence

Source

Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[307])

Book Ref

A Reaction

This is in defiance of Leibniz and Kant. His proposed explanation is not very convincing. Russell agreed with Nietzsche.


The 11 ideas with the same theme [there is no possibility of real knowledge a priori]:

Strongly believed a priori is not certain; it may just be a feature of our existence [Nietzsche]
No pictures are true a priori [Wittgenstein]
Quine's objections to a priori knowledge only work in the domain of science [Horwich on Quine]
Science is empirical, simple and conservative; any belief can hence be abandoned; so no a priori [Quine, by Horwich]
Logic, arithmetic and geometry are revisable and a posteriori; quantum logic could be right [Horwich on Quine]
What is considered a priori changes as language changes [Habermas, by Bowie]
Platonism defines the a priori in a way that makes it unknowable [Coffa]
The idea of the a priori is so obscure that it won't explain anything [Devitt]
Some knowledge must be empirical; naturalism implies that all knowledge is like that [Devitt]
The failure of key assumptions in geometry, mereology and set theory throw doubt on the a priori [Hart,WD]
We may have strong a priori beliefs which we pragmatically drop from our best theory [Boghossian]
