Rights cannot be objective; all values are subjective.
Read Nietzsche's Beyond Good and Evil
correct, and nietzsche would agree--but this is rather a peripheral theme to
beyond good and evil. nietzsche critiques his contemporaries', and
their antecedents', focus upon the
intent--deontological ethics--as opposed to earlier humans' focus upon consequentiality--he describes contemporary european morality as "herd-animal morality" (perhaps anticipating chomsky, et al, here). nevertheless, such is not the primal thrust of the text, and that you wrote here:
Yes, you can. The rational thing to do is pursue efficiency and uniformity.
suggests a rather
curious reading, if one is to assume that the above statement was in any sense informed by
bgae. nietzsche does not readily lend to literalist interpretations (unfortunately, such idiotic interpretations once reigned supreme on account of nietzsche's idiotic sister and her husband, and the national socialists, and finally, the most illiterate of them all, ayn rand), as metaphor, irony, devil's advocacy, and gross hyperbole were his weapons of choice.
rather,
bgae is a continuation of nietzsche's effort to subvert metaphysics, and the misguided obsession--and prioritization--of the noumenal over the phenomenal, and to affirm the necessarily perspectival and contextual nature of knowledge and our epistemological means. and so, pursuance of "truth" is misguided, and necessarily doomed to failure; rather we ought to embrace appearances and the superficial, so to speak. nietzsche is effectively, with respect to science, an anti-realist and asserts that it is in fact
we who have devised supposed "laws," "causes," whatnots. i do not believe that nietzsche would embrace a
rational pursuit of "efficiency and uniformity."
tangential to the topic at hand, but important nonetheless.
