Abstract:

The God Machine， an extreme proposal for moral enhancement introduced by Savulescu and Persson， has been criticized by scholars such as Harris and Sparrow for allegedly depriving individuals of free will， thereby lacking moral legitimacy. Two possible strategies have been proposed to defend the God Machine： first， denying that it impairs free will； second， rejecting the necessary connection between free will and moral responsibility. The first strategy is inadequate， plagued by weak arguments and category errors. In contrast， the revisionist theory supporting the second strategy effectively addresses these shortcomings， tackling challenges such as potential negative consequences， slippery slopes and manipulation， thereby providing a stronger defense for the God Machine.

Key words: moral enhancement, God Machine, free will, moral responsibility, revisionism
