If I had followed the multitude, I should not have studied philosophy.

Wise people are in want of nothing, and yet need many things. On the other hand, nothing is needed by fools, for they do not understand how to use anything, but are in want of everything.

He who is running a race ought to endeavor and strive to the utmost of his ability to come off victor; but it is utterly wrong for him to trip up his competitor, or to push him aside. So in life it is not unfair for one to seek for himself what may accrue to his benefit; but it is not right to take it from another.

Living virtuously is equal to living in accordance with one's experience of the actual course of nature

There could be no justice, unless there were also injustice; no courage, unless there were cowardice; no truth, unless there were falsehood.

Thought is the fountain of speech.

If I had followed the multitude, I should not have studied philosophy.
