When a man's life is over, it remains true that he was one sort of man and not another. A man who understands himself under the form of eternity knows the quality that eternally belongs to him, and knows that he cannot wholly die, even if he would, for when the movement of his life is over, the truth of his life remains.
Spinoza's Ethics and "De Intellectus Emendatione". (ed. 1910)
