“A library of wisdom, is more precious than all wealth, and all things that are desirable cannot be compared to it. Whoever therefore claims to be zealous of truth, of happiness, of wisdom or knowledge, must become a lover of books.”

“Then we shan’t regard anyone as a lover of knowledge or wisdom who is fussy about what he studies…”

“There are three classes of men; lovers of wisdom, lovers of honor, and lovers of gain.”

“And if the truth of all things that are is always in our soul, then the soul must be immortal, so you should take courage and whatever you do not happen to know, that is to remember, at present, you must endeavour to discover and recollect...I cannot swear to everything I have said in this argument – but one thing I am ready to fight for in word and deed, that we shall be better, braver and more active men if we believe it right to look for what we do not know, than if we think we cannot discover it and have no duty to seek it.”

“The rhetorician need not know the truth about things; he has only to discover some way of persuading the ignorant that he has more knowledge than those who know.”

“But the truth is, O men of Athens, that God only is wise; and by his answer he intends to show that the wisdom of men is worth little or nothing; he is not speaking of Socrates, he is only using my name by way of illustration, as if he said, He, O men, is the wisest, who, like Socrates, knows that his wisdom is in truth worth nothing.”

“Wars and revolutions and battles, you see, are due simply and solely to the body and its desires. All wars are undertaken for the acquisition of wealth; and the reason why we have to acquire wealth is the body, because we are slaves in its service.”
