To all those who still wish to talk about man, about his reign or his liberation, to all those who still ask themselves questions about what man is in his essence, to all those who wish to take him as their starting-point in their attempts to reach the truth, to all those who, on the other hand, refer all knowledge back to the truths of man himself, to all those who refuse to formalize without anthropologizing, who refuse to mythologize without demystifying, who refuse to think without immediately thinking that it is man who is thinking, to all these warped and twisted forms of reflection we can answer only with a philosophical laugh – which means, to a certain extent, a silent one.
