Those whom we call ancient were really new in all things, and properly constituted the infancy of mankind.

Extremes are for us as though they were not, and we are not within their notice. They escape us, or we them. This is our true state; this is what makes us incapable of certain knowledge and of absolute ignorance... This is our natural condition, and yet most contrary to our inclination; we burn with desire to find solid ground and an ultimate sure foundation whereon to build a tower reaching to the Infinite. But our whole groundwork cracks, and the earth opens to abysses.

The great mass of people judge well of things, for they are in natural ignorance, which is man's true state.

There is a God shaped vacuum in the heart of every man which cannot be filled by any created thing, but only by God, the Creator, made known through Jesus.

Men seek rest in a struggle against difficulties; and when they have conquered these, rest becomes insufferable.

The state of man is inconstancy, ennui, anxiety.

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.
