... there is no such thing as a rational world and a separate irrational world, but only one world containing both.

An impractical man--which he not only seems to be, but really is--will always be unreliable and unpredictable in his dealings with others. He will engage in actions that mean something else to him than to others, but he is at peace with himself about everything as long as he can make it all come together in a fine idea.

And since the possession of qualities presupposes that one takes a certain pleasure in their reality, all this gives us a glimpse of how it may all of a sudden happen to someone who cannot summon up any sense of reality — even in relation to himself — that one day he appears to himself as a man without qualities.

... there is a particular propensity in the world for people, wherever they appear in great numbers, to permit themselves collectively everything that would be forbidden them individually.

... nothing is more human than substituting the quantity of words and actions for their character. But using imprecise words is very similar to using lots of words, for the more imprecise a word is, the greater the area it covers.

I also believe that few people remain completely untouched by the thought that instead of the life they lead there might also be another, where all actions proceed from a very personal state of excitement. Where actions have meanings, not just causes. And where a person, to use a trivial word, is happy, and not just nervously tormenting himself.

Scientific reason, with its strict conscience, its lack of prejudice, and its determination to question every result again the moment it might lead to the least intellectual advantage, does in an area of secondary interest what we ought to be doing with the basic questions of life.
