Existence begins in every instant.

One can promise actions, but not feelings, for the latter are involuntary. He who promises to love forever or hate forever or be forever faithful to someone is promising something that is not in his power.

No more fiction, for now we calculate; but that we may calculate, we had to make fiction first.

The man of the future who will redeem us not only from the hitherto reigning ideal but also from that which was bound to grow out of it, the great nausea, the will to nothingness, nihilism; this bell stroke of noon and of the great decision that liberates the will again and restores its goal to the earth and his hope to man; this Antichrist and anti-nihilist; this victor over God and nothingness - he must come one day.

Examine the life of the best and most productive men and nations, and ask yourselves whether a tree which is to grow proudly skywards can dispense with bad weather and storms. Whether misfortune and opposition, or every kind of hatred, jealousy, stubbornness, distrust, severity, greed, and violence do not belong to the favourable conditions without which a great growth even of virtue is hardly possible?

No victor believes in chance.

Whoever has character also has his typical experience, which returns over and over again.
