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.
I took the train, it was good, it was empty.
The heavy weight of many a weary day / Not mine, and such as were not made for me.
And again: 'One may almost doubt if the wisest man'—say, Socrates—'has learned any thing of absolute value by living' (i, 10), meaning: if he has, it is not by living, but by, say, dying, or preparing to. But the practical, know-howsy flavor of Thoreau's comments in these paragraphs (the example, styled proverbially: knowing enough 'to fetch fresh fuel to keep the fire a-going') alludes to problems of survival, uncertain subsistence, preparation and provision, or as he'll style it later, 'getting a living'. So, to philosophize is to learn not to die?
