"The hottest love has the coldest end."

"Remember that there is nothing stable in human affairs; therefore avoid undue elation in prosperity, or undue depression in adversity."

"I honor and love you: but why do you who are citizens of the great and mighty nation care so much about laying up the greatest amount of money and honor And reputation, and so little amount wisdom and truth and the greatest improvement of the soul? Re you not ashamed of these?... I do nothing but go about persuading you all, not to take thought for your persons and your properties, but first and chiefly to care about the greatest improvement of the soul. I tell you that virtue is not given by more, but that from virtue comes money and every other good of man."

"Remember that there is nothing stable in human affairs; therefore avoid undue elation in prosperity, or undue depression in adversity."

"I will not yield to any man contrary to what is right, for fear of death, even if I should die at once for not yielding."

"Education is the kindling of a flame, not the filling of a vessel."

"It is better to change an opinion than to persist in a wrong one."

"Neither in war nor yet at law ought any man to use every way of escaping death. For often in battle there is no doubt that if a man will throw away his arms, and fall on his knees before his pursuers, he may escape death; and in other dangers there are other ways of escaping death, if a man is willing to say and do anything. The difficulty, my friends, is not in avoiding death, but in avoiding unrighteousness; for that runs faster than death."

"Do not trouble about those who practice philosophy, whether they are good or bad; but examine the thing itself well and carefully. And if philosophy appears a bad thing to you, turn every man from it, not only your sons; but if it appears to you such as I think it to be, take courage, pursue it, and practice it, as the saying is, 'both you and your house."

"Prefer knowledge to wealth, for the one is transitory, the other perpetual"

"Death may be the greatest of all human blessings."

"For the fear of death is indeed the pretense of wisdom, and not real wisdom, being a pretense of knowing the unknown; and no one know whether death, which men in their fear apprehend to be the greatest evil, may not be the greatest good. Is not this ignorance of a disgraceful sort, the ignorance which is the conceit that a man knows that he does not know?
