The only shame is to have none.

We must know where to doubt, where to feel certain, where to submit. He who does not do so, understands not the force of reason.

Justice and power must be brought together, so that whatever is just may be powerful, and whatever is powerful may be just.

Without the knowledge of our wretchedness, the knowledge of God creates pride. With it, the knowledge of God creates despair. The knowledge of Christ offers a third way, because in him we find both God and our wretchedness.

Nature imitates herself. A grain thrown into good ground brings forth fruit; a principle thrown into a good mind brings forth fruit. Everything is created and conducted by the same Master-the root, the branch, the fruits-the principles, the consequences.

The last advance of reason is to recognize that it is surpassed by innumerable things; it is feeble if it cannot realize that.

Let us, then, take our compass; we are something, and we are not everything. The nature of our existence hides from us the knowledge of first beginnings which are born of the nothing; and the littleness of our being conceals from us the sight of the infinite. Our intellect holds the same position in the world of thought as our body occupies in the expanse of nature.
