Hence we see that the matter has this deeper side also. But I have introduced it only because I wanted to make it clear that when the question becomes one of “thinking”, then one must go somewhat more deeply. Errors of thought slip out even among the most brilliant thinkers, and for a long time one does not see where the weak spot of the argument lies—as, for example, in the Kantian thought about the hundred possible and the hundred actual thalers. In thinking, one must always take account of the situation in which the thought has to be grasped.
