“If you have ever, sir, been through a breakup of a romantic relationship that involved great love, you will perhaps understand what I experienced. There is in such situations usually a moment of passion during which the unthinkable is said; this is followed by a sense of euphoria at finally being liberated; the world seems fresh as if seen for the first time then comes the inevitable period of doubt, the desperate and doomed backpedaling of regret; and only later, once emotions have receded, is one able to view with equanimity the journey through which one has passed.”

“All I want is' - and he uttered the final words through clenched teeth and with a sort of shame - 'to retain my freedom.'I should myself have thought,' said Jacques, 'that freedom consisted in frankly confronting situations into which one had deliberately entered, and accepting all one's responsibilities. But that, no doubt, is not your view.”

“We do not receive wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can make for us, which no one can spare us, for our wisdom is the point of view from which we come at last to regard the world. The lives that you admire, the attitudes that seem noble to you, have not been shaped by a paterfamilias or a schoolmaster, they have sprung from very different beginnings, having been influenced by evil or commonplace that prevailed round them. They represent a struggle and a victory.”

“...no one who has passed through the storm has ever regretted the journey. No one stands here and wishes to go back to the other side.”

“The world to come will be like this triangular railroad junction, raised to some unknown power. The earth has lived through several evolutionary stages - but following always natural laws. It is presently experiencing a new one, which follows constructive, conscious, and no less elemental laws. Regret for the passing of the old forms is like the grief of some antediluvian creature for the disappearance of a prehistoric habitat.”

“To me it seems that those sciences are vain and full of error which are not born of experience, mother of all certainty, first-hand experience which in its origins, or means, or end has passed through one of the five senses. And if we doubt the certainty of everything which passes through the senses, how much more ought we to doubt things contrary to these senses – ribelli ad essi sensi – such as the existence of God or of the soul or similar things over which there is always dispute and contention. And in fact it happens that whenever reason is wanting men to cry out against one another, which does not happen with certainties. For this reason we shall say that where the cry of controversy is heard, there is no true science, because the truth has one single end and when this is published, argument is destroyed for ever.”
