"Wonder is the only beginning of philosophy."

"Lack of activity destroys the good condition of every human being."

"Love is a good poet and accomplished in all the fine arts; for no one can give to another that which he has not himself, or teach that of which he has no knowledge. Who will deny that the creation of the animals is his doing? Are they not all the works of his wisdom, born and begotten of him? And as to the artists, do we not know that he only of them whom love inspires has the light of fame?"

"Every king springs from a race of slaves, and every slave had kings among his ancestors."

"Men say that everyone is naturally a lover of himself, and that it is right that it should be so. This is a mistake; for in fact the cause of all the blunders committed by man arises from this excessive self-love. For the lover is blinded by the object loved, so that he passes a wrong judgment upon what is just, good, and beautiful, thinking that he ought always to honor what belongs to himself, in preference to truth. For he who intends to be a great man ought to love neither himself nor his own things, but only what is just, whether it happens to be done by himself or by another."

"Justice will only exist where those not affected by injustice are filled with the same amount of indignation as those offended."

"Man...is a tame or civilized animal; never the less, he requires proper instruction and a fortunate nature, and then of all animals he becomes the most divine and most civilized; but if he be insufficiently or ill- educated he is the most savage of earthly creatures."

"Misanthropy ariseth from a man trusting another without having sufficient knowledge of his character, and, thinking him to be truthful, sincere, and honorable, finds a little afterwards that he is wicked, faithless, and then he meets with another of the same character. When a man experiences this often, and more particularly from those whom he considered his most dear and best friends, at last, having frequently made a slip, he hates the whole world, and thinks that there is nothing sound at all in any of them."

"No evil can happen to a good man, either in life or after death."

"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 endeavor 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."
