“People who are not in love fail to understand how an intelligent man can suffer because of a very ordinary woman. This is like being surprised that anyone should be stricken with cholera because of a creature so insignificant as the common bacillus.”

“People who, not being in love themselves, feel that a clever man should only be unhappy about a person who is worth his while; which is rather like being astonished that anyone should condescend to die of cholera at the bidding of so insignificant a creature as the comma bacillus.”

“Indeed, the truth that many people never understand, until it is too late, is that the more you try to avoid suffering, the more you suffer, because smaller and more insignificant things begin to torture you, in proportion to your fear of being hurt. The one who does most to avoid suffering is, in the end, the one who suffers the most: and his suffering comes to him from things so little and so trivial that one can say that it is no longer objective at all. It is his own existence, his own being, that is at once the subject and the source of his pain, and his very existence and consciousness is his greatest torture.”

“As a jealous man, I suffer four times over: because I am jealous, because I blame myself for being so, because I fear that my jealousy will wound the other, because I allow myself to be subject to a banality: I suffer from being excluded, from being aggressive, from being crazy, and from being common.”

“Extinction catches Man by surprise because no one can even imagine that such a catastrophe can happen to an intelligent species.”

“People who speak or act in an ordinary fashion are most likely to be those who have been the recipients of higher experiences. But because they do not rage around, wild-eyed, people think that they are very ordinary folk and therefore not aware of anything unknown to the general run of man.”
