If not always, it would certainly be interesting today for philosophy to return to its beginnings as an antidote to its own misrepresentation. To teach it, it would be better to pretend that nothing was ever written down and expound concepts as if they were being taught for the first time. The teacher would then teach in the open air with the pupils sitting in a circle, and when he said “act”, he would show precisely the meaning of this word, so that, for the rest of their lives, the disciples would have in mind the actual act witnessed, and would not give in to the temptation to apply this word in a sense that was detached from the one the teacher made them witness. And so for all the important words. It is always profitable to secure the knowledge of a patent reality to which one must turn one’s eyes and without which reasoning is a waste.
