“We are fools to depend upon the society of our fellow-men. Wretched as we are, powerless as we are, they will not aid us; we shall die alone. We should therefore act as if we were alone, and in that case should we build fine houses, etc.? We should seek the truth without hesitation; and, if we refuse it, we show that we value the esteem of men more than the search for truth.”

“It is absurd of us to rely on the company of our fellows, as wretched and helpless as we are; they will not help us; we shall die alone.We must act then as if we were alone. If that were so, would we build superb houses, etc.? We should unhesitatingly look for the truth. And, if we refuse, it shows that we have a higher regard for men's esteem than for pursuing the truth.”

“Let each of us examine his thoughts; he will find them wholly concerned with the past or the future. We almost never think of the present, and if we do think of it, it is only to see what light is throws on our plans for the future. The present is never our end. The past and the present are our means, the future alone our end. Thus we never actually live, but hope to live, and since we are always planning how to be happy, it is inevitable that we should never be so.”

“We naturally believe we are more capable of reaching the centre of things than of embracing their circumference, and the visible extent of the world is visibly greater than we. But since we in our turn are greater than small things, we think we are more capable of mastering them, and yet it takes no less capacity to reach nothingness than the whole. In either case it takes an infinite capacity, and it seems to me that anyone who had understood the ultimate principles of things might also succeed in knowing infinity. One depends on the other, and one leads to the other. These extremes touch and join by going in opposite directions, and they meet in God and God alone.”

“Two contrary reasons. We must begin with that, otherwise we cannot understand anything and everything is heretical. And even at the end of each truth we must add that we are bearing the opposite truth in mind.”

“Truth is so obscure in these times, and falsehood so established, that, unless we love the truth, we cannot know it.”

“If our state were really happy, we should not need to take our minds off it in order to make ourselves happy.”
