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

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.
