Single Idea 4539

[filed under theme 12. Knowledge Sources / A. A Priori Knowledge / 7. A Priori from Convention ]

Full Idea

The basic laws of logic (identity and contradiction) are said to be forms of pure knowledge because they precede experience. But these are not forms of knowledge at all! They are regulative articles of belief.

Gist of Idea

The forms of 'knowledge' about logic which precede experience are actually regulations of belief

Source

Friedrich Nietzsche (The Will to Power (notebooks) [1888], §530)

Book Ref

A Reaction

This is a standard objection to foundationalism - that the basic beliefs (of reason, or raw experience) are not actually knowledge. We can all speculate about their origin and basis. Personally I think 'truth' must be somewhere in the explanation.


The 6 ideas with the same theme [a priori knowledge simply reports our social consensus]:

If, as Kant says, arithmetic and logic are contributed by us, they could change if we did [Russell on Kant]
The forms of 'knowledge' about logic which precede experience are actually regulations of belief [Nietzsche]
We can maintain a priori principles come what may, but we can also change them [Lewis,CI]
By changing definitions we could make 'a thing can't be in two places at once' a contradiction [Ayer]
Examination of convention in the a priori begins to blur the distinction with empirical knowledge [Quine]
We treat basic rules as if they were indefeasible and a priori, with no interest in counter-evidence [Field,H]
