Ordinary language is all right.
One could divide humanity into two classes:
those who master a metaphor, and those who hold by a formula.
Those with a bent for both are too few, they do not comprise a class.
(Compare to the last line of William Slothrop's hymn, on the last page of Gravity's Rainbow.)
'Please, God, make me a stone' - a simile here would be a mistake, would drain the prayer of its gravity.
'plainly put, man as culture-consumer is, in an insidious way, dissatisfied with man as culture-producer'
'To have a philosophical mind is to participate, by knowledge, in the life and being of many by not treating oneself as a fixed individual, one and unchanging.'
Needless to say: when preoccupied with worry about understanding everything one in fact comes to understand very little.
Some nights, I am overwhelmed by the necessity of understanding everything there is. It is as if there is too much air to breathe and I have to catch up. But there is not just too much; there is more than I can ever breathe.
