"Is it not altogether absurd that, under actual circumstances, the average man does not feel spontaneously, and without being preached at, an ardent enthusiasm for those sciences and the related ones of biology?… Every day furnishes a new invention which this average man utilises. Every day produces a new anesthetic or vaccine from which this average man benefits. … How is it, nevertheless, that there is no sign of the masses imposing on themselves any sacrifice of money or attention in order to endow science more worthily? Far from this being the case, the post-war period has converted the man of science into a new social pariah."

“As one advances in life, one realises more and more that the majority of men — and of women — are incapable of any other effort than that strictly imposed on them as a reaction to external compulsion. And for that reason, the few individuals we have come across who are capable of a spontaneous and joyous effort stand out isolated, monumentalised, so to speak, in our experience. These are the select men, the nobles, the only ones who are active and not merely reactive, for whom life is a perpetual striving, an incessant course of training. Training = askesis. These are the ascetics.”

“I know well that many of my readers do not think as I do. This also is most natural and confirms the theorem. For although my opinion turn out erroneous, there will always remain the fact that many of those dissentient readers have never given five minutes' thought to this complex matter. How are they going to think as I do? But by believing that they have a right to an opinion on the matter without previous effort to work one out for themselves, they prove patently that they belong to that absurd type of human being which I have called the "rebel mass." It is precisely what I mean by having one's soul obliterated, hermetically closed. Here it would be the special case of intellectual hermetism.”

“The nineteenth century, utilitarian throughout, set up a utilitarian interpretation of the phenomenon of life which has come down to us and may still be considered as the commonplace of everyday thinking. … An innate blindness seems to have closed the eyes of this epoch to all but those facts which show life as a phenomenon of utility”

“He is one who, out of all that has to be known in order to be a man of judgment, is only acquainted with one science, and even of that one only knows the small corner in which he is an active investigator. He even proclaims it as a virtue that he takes no cognisance of what lies outside the narrow territory specially cultivated by himself, and gives the name of "dilettantism" to any curiosity for the general scheme of knowledge.”

“This fighting-shy of every obligation partly explains the phenomenon, half ridiculous, half disgraceful, Of the setting-up in our days of the platform of "youth" as youth. … In comic fashion people call themselves "young," because they have heard that youth has more rights than obligations, since it can put off the fulfilment of these latter to the Greek Kalends of maturity. …he astounding thing at present is that these take it as an effective right precisely in order to claim for themselves all those other rights which only belong to the man who has already done something.”

“I have always thought that clarity is a form of courtesy that the philosopher owes; moreover, this discipline of ours considers it more truly a matter of honor today than ever before to be open to all minds … This is different from the individual sciences which increasingly between the treasure of their discoveries and the curiosity of the profane the tremendous dragon of their closed terminology.”
