When it's time to die, let us not discover that we have never lived.

I hardly know an intellectual man, even, who is so broad and truly liberal that you can think aloud in his society.

You may rely on it that you have the best of me in my books, and that I am not worth seeing personally, the stuttering, blunderingclod-hopper that I am. Even poetry, you know, is in one sense an infinite brag and exaggeration. Not that I do not stand on all that I have written,--but what am I to the truth I feebly utter?

We live thick and are in each other's way, and stumble over one another, and I think we thus lose some respect for one another.

Undoubtedly, in the most brilliant successes, the first rank is always sacrificed.

The true man of science will know nature better by his finer organization; he will smell, taste, see, hear, feel, better than other men. His will be a deeper and finer experience. We do not learn by inference and deduction and the application of mathematics to philosophy, but by direct intercourse and sympathy. It is with science as with ethics,--we cannot know truth by contrivance and method; the Baconian is as false as any other, and with all the helps of machinery and the arts, the most scientific will still be the healthiest and friendliest man, and possess a more perfect Indian wisdom.

Do what nobody else can do for you. Omit to do anything else.
