“Action is the activity of the rational soul, which abhors irrationality and must combat it or be corrupted by it. When it sees the irrationality of others, it must seek to correct it, and can do this either by teaching or engaging in public affairs itself, correcting through its practice. And the purpose of action is to enable philosophy to continue, for if men are reduced to the material alone, they become no more than beasts.”

“[T]he concern of man is not his future but his present, not the world but his soul. We must be just, we must strive, we must engage ourselves with the business of the world for our own sake, because through that, and through contemplation in equal measure, our soul is purified and brought closer to the divine. ... Thought and deed conjoined are crucial. ... The attempt must be made; the outcome is irrelevant. Right action is a pale material reflection of the divine, but reflection it is, nonetheless. Define your goal and exert reason to accomplish it by virtuous action; successs or failure is secondary.”

“The point of civilization is to be civilized; the purpose of action is to perpetuate society, for only in society can philosophy truly take place.”

“Philosophy cannot be extinguished, though men will try ... The spirit seeks the light, that is its nature. It wishes to return to its origin, and must forever try to reach enlightenment.”

“Olivier took a deep breath, then turned and bowed in farewell. Gersonides nodded in return, then thought of something."The manuscript you brought me, by that bishop. It argues that understanding is more important than movement. That action is virtuous only if it reflects pure comprehension, and that virtue comes from the comprehension, not the action."Olivier frowned. "So?""Dear boy, I must tell you a secret.""What?""I do believe it is wrong.”

“[Men] prefer the foolish belief and the passions of the earth [to the enlightenment of their souls]. They believe the absurd and shrink from the truth.""No, they do not. They are afraid, that is all. And they must remain on earth until they come to the way of leaving it.""And how do they leave? How is the ascent made? Must one learn virtue?"Here she laughs. "You have read too much, and learned too little. Virtue is a road, not a destination. Man cannot be virtuous. Understanding is the goal. When that is achieved, the soul can take wing.”

“Virtue comes through contemplation of the divine, and the exercise of philosophy. But it also comes through public service. The one is incomplete without the other. Power without wisdom is tyranny; wisdom without power is pointless.”
