... he calls the idea of “objective” Good and Evil as “the most maleficent lie” ever told.
Sounds similar to Hagel's Dialectical Materialism on which Marx and Engels based their theories.
Great catch, Mind-numbed Robot!
Hegelian dialectics applied to this question: Thesis (i.e., Good)–Antithesis (i.e., Evil) resolve into "Synthesis" (whatever that might be) — which becomes the next "thesis" invoking a new "antithesis," resolvable into a new "synthesis." And so this process continues ad infinitum.
But it never "resolves" into anything definite, let alone "objective." It is merely an operation of abstract mind detached from reality as experienced, and is, as such, relentlessly subjective. IMHO, it is the highest form of the fine art of "navel gazing" ever produced in human history.
But it has the dubious virtue of promising us that by use of this method, we can move "beyond" Good and Evil.... Marx and Engels evidently caught onto that aspect right away. Their resulting "systems" speak for themselves.
Thanks again, Mind-numbed Robot, for your excellent insight!
