Men that love wisdom must be acquainted with very many things indeed.

Let a man once overcome his selfish terror at his own finitude, and his finitude is, in one sense, overcome.

Above all things let us never forget that mankind constitutes one great brotherhood; all born to encounter suffering and sorrow, and therefore bound to sympathize with each other

It is the mark of an educated mind to be able to entertain a thought without accepting it.

Who would give a law to lovers? Love is unto itself a higher law.

It would be better for me... that multitudes of men should disagree with me rather than that I, being one, should be out of harmony with myself.
