The sceptic will say, 'It may well be true that this system of equations is reasonable from a logical standpoint, but this does not prove that it corresponds to nature.' You are right, dear sceptic. Experience alone can decide on truth.
We may climb into the thin and cold realm of pure geometry and lifeless science, or sink into that of sensation. Between these extremes is the equator of life, of thought, or spirit, or poetry,--a narrow belt.
Empirical science is apt to cloud the sight, and, by the very knowledge of functions and processes, to bereave the student of themanly contemplation of the whole.

One should not understand this compulsion to construct concepts, species, forms, purposes, laws ('a world of identical cases') as if they enabled us to fix the real world; but as a compulsion to arrange a world for ourselves in which our existence is made possible:-we thereby create a world which is calculable, simplified, comprehensible, etc., for us.

The truth may be puzzling. It may take some work to grapple with. It may be counterintuitive. It may contradict deeply held prejudices. It may not be consonant with what we desperately want to be true. But our preferences do not determine what's true.
The best thing we're put here for's to see; The strongest thing that's given us to see with's a telescope. Someone in every town, seems to me, owes it to the town to keep one.

'What's the use of their having names the Gnat said, 'if they won't answer to them?' 'No use to them,' said Alice; 'but it's useful to the people who name them, I suppose. If not, why do things have names at all?' 'I can't say,' the Gnat replied.
We are not clear as to the role in life of these chemicals; nor are we clear as to the role of the physician. You know, of course, that in ancient times there was no clear distinction between priest and physician.
