The most peculiar of all the peculiarities of the word "soul", however, is that young people cannot pronounce it without laughing. Even Diotima and Arnheim were shy of using it without a modifier, for it is still possible to speak of having a great, noble, craven, daring, or debased soul, but to come right out with "my soul" is something one simply cannot bring oneself to do. It is distinctinly an older person's word, and this can only be understood by assuming that in the course of life people become more and more aware of something for which they urgently need a name they cannot find until they finally resort, reluctantly, to the name they had originally despised.
