In Chapter 8 of Nihilism (entitled 'The New Valuation') Heidegger continues to comment on and elucidate para 12 (B) in Bk I ('European Nihilism') of Nietzsche's The Will to Power. Nietzsche ends that paragraph thus:
"All the values by means of which we have tried so far to render the world estimable for ourselves and which then proved inapplicable and therefore devaluated the world--all these values are, psychologically considered, the results of certain perspectives of utility, designed to maintain and increase human constructs of domination--and they have been falsely projected into the essence of things. What we find here is still the hyperbolic naivete of man: positing himself as the meaning and measure of the value of things."
'Nietzsche is saying that the essence of values has its ground in "constructs of domination." Values are essentially related to "domination". Dominance is the being in power of power. Values are bound to the will to power; they depend on it as the proper essence of power.'
