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?
Friedrich NietzscheSins are indispensable to every society organized on an ecclesiastical basis; they are the only reliable weapons of power; the priest lives upon sins; it is necessary to him that there be sinning.
Friedrich Nietzsche
