Friedrich Wilhelm Nietzsche (1844-1900)
"All psychology has hitherto remained anchored to moral prejudices and timidities: it has not ventured into the depths. To conceive it as morphology and the development-theory of the will to power, as I conceive it - has never yet so much as entered the mind of anyone else: in so far as it is permissible to see in what has hitherto been written a symptom of what has hitherto been kept silent. The power of moral prejudices has penetrated deep into the most spiritual world, which apparently is the coldest and most free of presuppositions - and, as goes without saying, has there acted in a harmful, inhibiting, blinding, distorting fashion. A genuine physio-psychology has to struggle with unconscious resistances in the heart of the investigator, it has 'the heart' against it: even a theory of the mutual dependence of the 'good' and the 'wicked' impulses causes, as a more refined immorality, revulsion to a conscience still strong and hearty - and even more a theory of the derivation of all good impulses from wicked ones. Supposing, however, that someone goes so far as to regard the emotions of hatred, envy, covetousness, and lust for domination as life-conditioning emotions, as something which must be fundamentally and essentially be present in the total economy of life, consequently must be heightened further if life is to heightened further - he suffers from such a judgement as from seasickness. And yet even this hypothesis is far from being the strangest and most painful in this tremendous, still almost unexplored realm of dangerous knowledge - and there are in fact a hundred good reasons why everybody should keep away from it who - can! On the other hand: if your ship has driven into these seas, very well! Now clench your teeth! Keep your eyes open! Keep a firm hand on the helm! - We sail straight over morality and past it, we flatten, we crush perhaps what is left of our own morality by venturing to voyage thither - but what do we matter! Never yet has a deeper world of insight revealed itself to daring travellers and adventurers..."
