What is man but a mass of thawing clay?

Probably if our lives were more conformed to nature, we should not need to defend ourselves against her heats and colds, but findher our constant nurse and friend, as do plants and quadrupeds.

The object of love expands and grows before us to eternity, until it includes all that is lovely, and we become all that can love.

For one that comes with a pencil to sketch or sing, a thousand come with an axe or rifle. What a coarse and imperfect use Indiansand hunters make of nature! No wonder that their race is so soon exterminated.

I find that the respectable man, so called, has immediately drifted from his position, and despairs of his country, when his country has more reason to despair of him. He forthwith adopts one of the candidatesas the only available one, thus proving that he is himself available for any purposes of the demagogue. His vote is of no more worth than that of any unprincipled foreigner or hireling native, who may have been bought.

He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one. Mathematics should be mixed not only with physics but with ethics; that is mixed mathematics. The fact which interests us most is the life of the naturalist. The purest science is still biographical.

Nature is as well adapted to our weakness as to our strength.
