It is your own assent to yourself, and the constant voice of your own reason, and not of others, that should make you believe.

To go beyond the bounds of moderation is to outrage humanity.

If man made himself the first object of study, he would see how incapable he is of going further. How can a part know the whole?

Pride counterbalances all our miseries, for it either hides them, or, if it discloses them, boasts of that disclosure. Pride has such a thorough possession of us, even in the midst of our miseries and faults, that we are prepared to sacrifice life with joy, if it may but be talked of.

Human life is thus only an endless illusion. Men deceive and flatter each other. No one speaks of us in our presence as he does when we are gone. Society is based on mutual hypocrisy.

We know that there is an infinite, and we know not its nature. As we know it to be false that numbers are finite, it is therefore true that there is a numerical infinity. But we know not of what kind; it is untrue that it is even, untrue that it is odd; for the addition of a unit does not change its nature; yet it is a number, and every number is odd or even (this certainly holds of every finite number). Thus we may quite well know that there is a God without knowing what He is.

One-half of life is admitted by us to be passed in sleep, in which, however, it may appear otherwise, we have no perception of truth, and all our feelings are delusions; who knows but the other half of life, in which we think we are awake, is a sleep also, but in some respects different from the other, and from which we wake when we, as we call it, sleep. As a man dreams often that he is dreaming, crowding one dreamy delusion on another.
