Nietzsche reduces all knowledge claims to will-to-power purposes

Evidence

Nor is thought itself exempt from this struggle: modern scien­ tific rationality is a particularly successful variant of the will to power, its urge to dominate nature originating in Plato’s claim that thought can uncover the inner structure of an antecedently existing, and indeed unchanging reality; the only attitude appropriate to the seething heterogeneity of the actual world is perspectivism, which recognizes every thought as an interpreta­ tion, valid only within a conceptual framework the grounds for whose acceptance lie not in any supposed correspondence with reality, but in the purpose, construable ultimately in terms of the will to power, which it serves. — Alex Callinicos, Against Postmodernism, 271
