Every sweet has its sour; every evil its good.

For the existing world is not a dream, and cannot with impunity be treated as a dream; neither is it a disease; but it is the ground on which you stand, it is the mother of whom you were born.

Do not be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better. What if they are a little coarse and you may get your coat soiled or torn? What if you do fail, and get fairly rolled in the dirt once or twice? Up again, you shall never be so afraid of a tumble.

In strict science, all persons underlie the same condition of an infinite remoteness. Shall we fear to cool our love by mining forthe metaphysical foundation of this elysian temple? Shall I not be as real as the things I see? If I am, I shall not fear to know them for what they are.

The invariable mark of wisdom is to see the miraculous in the common.

Meet your failure nobly, and it will not differ from success.

Nature does not cocker us: we are children, not pets: she is not fond: everything is dealt to us without fear or favor, after severe universal laws.
