What a marvellous book:
"Prof. Eaton: More abstract than concrete?
Dr. Jung: You can see these qualities best through practical examples. For instance, the Logos element, being a principle of discrimination, not only allows one but forces one to give equal dignity to any object of thinking or observation. It enables a man to devote himself with almost religious concentration to the classification of lice, or to the different qualities of faeces, to put it quite drastically, as well as to counting the stars. To make a picture of it, suppose there are a series of laboratories. In No. 1 is the observatory of a man who has devoted himself for years to astronomical researches. In the next laboratory is the man who is classifying lice, sixty thousand different specimens, a most interesting enterprise. And in the third is a man tremendously interested in the different qualities of faeces, a very unsavoury undertaking. Yet every man is working with the same concetration, the same spirit. Now what is Eros, represented by a woman, doing in that situation? Let us say she is the charwoman in the place. She finds the astronomer a terribly disagreeable man, hard and cold; he never gives her a tip, and naturally he is a bachelor. Mr. Professor Concerned-with-lice would be quite a nice man if he were not always interested in those ugly things; he occasionally gives her a tip, he is married and has very nice children, he is perfectly respectable and he has a great-uncle somewhere. She knows all that. That is relatedness, you see. It is an entirely different aspect of the world. The man devoted to the stars, who sits there passionately attending to his work, is absolutely unaware of the fact that he can fall in love with a woman. He thinks that falling in love is a kind of illness which happens in early youth and which one combats by marrying- As a man said to me: ""Just in order to get through with the damned thing."" That is Logos."
The only pity is that we didn't learn what THE THIRD Herr Professor was like... (This one point is missing.)
