Niccolò Machiavelli, The Prince

"Everyone sees what you appear to be, few experience what you really are."

"Because there are three classes of intellects: one which comprehends by itself; another which appreciates what others comprehend; and a third which neither comprehends by itself nor by the showing of others; the first is the most excellent, the second is good, the third is useless."

"Is it better to be loved or feared?"

"Men ought either to be well treated or crushed, because they can avenge themselves of lighter injuries, of more serious ones they cannot; therefore the injury that is to be done to a man ought to be of such a kind that one does not stand in fear of revenge."

"God is not willing to do everything, and thus take away our free will and that share of glory which belongs to us."

"The first method for estimating the intelligence of a ruler is to look at the men he has around him."

"A prince must not have any other object nor any other thought… but war, its institutions, and its discipline; because that is the only art befitting one who commands."

"Because there are three classes of intellects: one which comprehends by itself; another which appreciates what others comprehend; and a third which neither comprehends by itself nor by the showing of others; the first is the most excellent, the second is good, the third is useless."
