Abstract: As the founder of western modern meta-ethics,G.E.Moore spared no effort to clear the normative ethics.In the course of giving normative-ethics and meta-ethics tit for tat,Moore regarded leaders of normative-ethics——Hegel and Kant as the main criticism target to point out the non-rationality of Hegel’s "Organic Whole" and the disadvantages of Kant’s "Metaphysics" ethics.Today,It seems that this kind of criticism is very rational.
