We ourselves introduce that order and regularity in the appearance which we entitle "nature". We could never find them in appearances had we not ourselves, by the nature of our own mind, originally set them there.

An organized product of nature is that in which all the parts are mutually ends and means.

A single line in the Bible has consoled me more than all the books I ever read besides.

I am myself by inclination an investigator.

By a lie a man throws away and, as it were, annihilates his dignity as a man. A man who himself does not believe what he tells another ... has even less worth than if he were a mere thing. ... makes himself a mere deceptive appearance of man, not man himself.

The busier we are, the more acutely we feel that we live, the more conscious we are of life.

Every man is to be respected as an absolute end in himself; and it is a crime against the dignity that belongs to him as a human being, to use him as a mere means for some external purpose.
