“Yes the truth is that men's ambition and their desire to make money are among the most frequent causes of deliberate acts of injustice.”

“It is of the nature of desire not to be satisfied, and most men live only for the gratification of it.”

“habits of virtue and vice are caused by acts”

“All men by nature desire to know.”

“For man, when perfected, is the best of animals, but, when separated from law and justice, he is the worst of all; since armed injustice is the more dangerous, and he is equipped at birth with the arms of intelligence and with moral qualities which he may use for the worst ends. Wherefore, if he have not virtue, he is the most unholy and the most savage of animals, and the most full of lust and gluttony. But justice is the bond of men in states, and the administration of justice, which is the determination of what is just, is the principle of order in political society.”

“All human actions have one or more of these seven causes: chance, nature, compulsion, habit, reason, passion, and desire.”

“Some men are just as sure of the truth of their opinions as are others of what they know.”
