A friend is Janus-faced: he looks to the past and the future. He is the child of all my foregoing hours, the prophet of those to come, and the harbinger of a greater friend.

A man of thought must feel the thought that is parent of the universe: that the masses of nature do undulate and flow.

Nothing in nature is exhausted in its first use...In God, every end is converted into a new means.

There is no luck in literary reputation. They who make up the final verdict upon every book are not the partial and noisy readers of the hour when it appears; but a court as of angels, a public not to be bribed, not to be entreated, and not to be overawed, decides upon every man's title to fame.

If a man fasten his attention on a single aspect of truth and apply himself to that alone for a long time, the truth becomes distorted and not itself but falsehood.

We seek our friend not sacredly, but with an adulterate passion which would appropriate him to ourselves.

Cultivate the habit of being grateful... and ...give thanks continuously.
