To learn something new, take the path that you took yesterday.

One may summon his philosophy when they are beaten in battle, not till then.

I want nothing less than a faith founded upon a rock, faith in the constitution of things.

If the October days were a cordial like the sub-acids of fruit, these are a tonic like the wine of iron. Drink deep or be careful how you taste this December vintage. The first sip may chill, but a full draught warms and invigorates.

Science is a capital or fund perpetually reinvested; it accumulates, rolls up, is carried forward by every new man. Every man of science has all the science before him to go upon, to set himself up in business with. What an enormous sum Darwin availed himself of and reinvested! Not so in literature; to every poet, to every artist, it is still the first day of creation, so far as the essentials of his task are concerned. Literature is not so much a fund to be reinvested as it is a crop to be ever new-grown.
