Actions which produce good consequences are not for that reason good. Success and failure in accomplishing goals of action is of no moral significance. Thus, its goodness does not and cannot depend upon anything other than itself. It cannot be value-neutral. Kant's Anti-Eudaimonism and Scepticism about the Practical Function of Reason Kant holds that only a good will, not happiness, is intrinsically good.
Happiness is, according to Aristotelian theory, the final end or human good.
The idea that it is reason rather than natural impulse which guides action for the sake of happiness is false. Parts of living organisms perform their proper function by serving the survival and welfare or happiness of the whole organism. Natural instinct rather than reason provides better for happiness. Mastery of nature liberates master from nature's necessities. Liberation from necessity brings luxury.
