A problem arises when the thinker distances himself from the Now by comparing and desiring

In the Now there are no problems, only facts, existential conditions.

A problem arises when the thinker distances himself from the Now by comparing, wishing etc.

The thinker slides off from the Now´s facts.

And the Now´s facts, seen from the thinker´s perspective, the past and the future, thereby become a problem.
