As Kierkegaard insisted from his theistic perspective, so Nietzsche also argues from his naturalistic one: whoever accepts the whole must accept as well the negative, resented, embittering, contrary elements in that whole. If life and character and nature and society truly are wholes, then everything in them is in some way essential to that whole; and we cannot grasp that whole by means of value-judgments if values are INHERENTLY DISCRIMINATORY or divisive functions of our intelligence. Values drive rifts between options, they exist for the sake of the natural powers of the will which (so to speak) needs its food cut up into willable portions or differentiated options.
The worldview of modern scientism and capitalism are profoundly wrongheaded, rooted in an artificialism and arbitrarialism that cannot begin to see the primordial truth of the way nature actually works, in animals and in ourselves as well. All modern culture and ideology that try to disestablish these principles -- radical egalitarianism, capitalist or bourgeois materialist-artificialist hierarchicalism, arbitrarial libertarianism, etc. -- are flying in the face of the headwinds of both nature and values, the tides of human nature and human character. But these ideologies' fallacies are incomprehensible to them just because their culture systematically prohibits them from thinking about issues at the level of structural principles, of ultimate preconceptions: nothing but good pedestrian mechanical bourgeois logic, as remote as it can possibly be from philosophy.
