“I have no other passion to keep me in breath. What avarice, ambition, quarrels, law suits do for others who, like me, have no particular vocation, love would much more commodiously do; it would restore to me vigilance, sobriety, grace, and the care of my person; it would reassure my countenance, so that the grimaces of old age, those deformed and dismal looks, might not come to disgrace it; would again put me upon sound and wise studies, by which I might render myself more loved and esteemed, clearing my mind of the despair of itself and of its use, and redintegrating it to itself; would divert me from a thousand troublesome thoughts, a thousand melancholic humours that idleness and the ill posture of our health loads us withal at such an age; would warm again, in dreams at least, the blood that nature is abandoning; would hold up the chin, and a little stretch out the nerves, the vigour and gaiety of life of that poor man who is going full drive towards his ruin.”
― Michel de Montaigne, Essays

“And this puts me in mind of that rich gentleman of Rome, who had been solicitous, with great expense, to procure men that were excellent in all sorts of science, whom he had always attending his person, to the end, that when amongst his friends any occasion fell out of speaking of any subject whatsoever, they might supply his place, and be ready to prompt him, one with a sentence of Seneca, another with a verse of Homer, and so forth, every one according to his talent; and he fancied this knowledge to be his own, because it was in the heads of those who lived upon his bounty; as they, also, do whose learning consists in having great libraries.”
― Michel de Montaigne

“[...T]he ways of God have been manifested beyond example: the sea is divided, the cloud has led the way, the rock has poured forth water, it has rained manna, everything has contributed to your greatness; you ought to do the rest. God is not willing to do everything, and thus take away our free will and that share of glory which belongs to us.”
― Niccolò Machiavelli, The Prince

“Would I fortify myself against the fear of death, it must be at the expense of Seneca: would I extract consolation for myself or my friend, I must borrow it from Cicero.  I might have found it in myself, had I been trained to make use of my own reason.  I do not like this relative and mendicant understanding; for though we could become learned by other men's learning, a man can never be wise but by his own wisdom.”
― Michel de Montaigne
