Because thinking is primary (from Rudolf Steiner) we immediately need to distinguish thinking - because thinking knows itself to be self-contradicting. We need (at least) a thinking that can withstand the scrutiny of thinking.
We need, that is, a coherent Primary thinking - i.e. which satisfies all other kinds of thinking - which explains all other kinds of thinking - which explains itself.
...Although the conviction that this explanation is true must be intuitive.
In short, we need a thinking that rests solidly upon intuition, and which is never contradicted by itself.
A thinking that is both coherent and validly experienced.
To move to metaphysics; why should intuitive validity be true? (Rather than a delusion.) Only if it is built into Men by a personal creator god... This requires, minimally, a god that has equipped Man with the ability to know reality (including god itself).
However, this ability to know reality is Not the same as Man's original essence of being; Not the same as Man's agency.
Thinking is primary, agency is primary...
Therefore, there is an intrinsic potential conflict between agency and intuitive thinking.
In other words, Man can know - by Primary thinking; but Man's agency must choose to know.
