The science [geometry] is pursued for the sake of the knowledge of what eternally exists, and not of what comes for a moment into existence, and then perishes.
Nothing can be more absurd than the practice that prevails in our country of men and women not following the same pursuits with all their strengths and with one mind, for thus, the state instead of being whole is reduced to half.

That makes me think, my friend, as I have often done before, how natural it is that those who have spent a long time in the study of philosophy appear ridiculous when they enter the courts of law as speakers. Those who have knocked about in courts and the like from their youth up seem to me, when compared with those who have been brought up in philosophy and similar pursuits, to be as slaves in breeding compared with freemen.
If one sins against the laws of proportion and gives something too big to something too small to carry it - too big sails to too small a ship, too big meals to too small a body, too big powers to too small a soul - the result is bound to be a complete upset.
