Kant was right, that the thought is forming, modifying, coloring in compliance with the pattern of experience.
The function of the thought is to communicate itself, not to be in the experiencing condition.
When the experience has gone, then the thought takes over, names it, and places it within the known´s categories and forms of experience. Therefore Kant discriminated between reality in itself – ”Das Ding an Sich” (the things in themselves) – and the reality as it appears for us – the world of experience or phenomena ”erscheinungen” (the things as sensed appearance); that is: our perspective.
So, the thought can´t enter the unknown, and therefore it can never discover or experience reality. The thought is a result of the known, of our perspective, which is time as such, and therefore it can´t embrace the unknown, the timeless, that, which can't be known.
