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.
It is also why school sucks and recess rules.
The more widely read a classic is, the more it sucks to read, because you know you're supposed to think things about it, and you want to, but you know that the things you think won't satisfy anyone until you also read the crap everyone says about it, which makes you kind of not even want to think the things you think about it.
This is why reading Emerson is better than reading Kant.
