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 on 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.
PlatoIn heaven there is laid up a pattern which he who chooses may behold, and beholding, set his own house in order. The time has now arrived at which they must raise the eye of the soul to the Universal Light which lightens all things. With the eye ever directed toward things fixed and immutable which neither injure nor are injured - these they cannot help imitating. But I quite admit the difficulty of believing that in every man there is an eye of the soul which by the right direction is re-illumined, and is more precious far than ten thousand bodily eyes.
