 None of these answers is without difficulties. While there are contemporary defenders of Hobbesian moral theories (see Gauthier 1986), there is no one who is on record defending Hobbes’s interesting combination of a thoroughgoing subjectivism about the good along with an account of a dominant substantive good around which the moral rules are formulated. The basic reason for this just seems to be that Hobbes’s arguments that the human desire for self-preservation is such an entirely dominant desire are implausible, and there do not seem to be any better arguments available. The Platonic version of the view has struck many as both too metaphysically ornate to be defensible, on one hand, and as not fitting very well with a conception of ethics grounded in nature, on the other. While the Aristotelian version of the view has also been charged with some of the metaphysical excesses that the Platonist view allegedly countenances, most contemporary natural law theory is Aristotelian in its orientation, holding that there is still good reason to hold to an understanding of flourishing in nature and that none of the advances of modern science has called this part of the Aristotelian view into question. (For defenses of such Aristotelian accounts of the good, see Foot 2001, Thompson 1995, and Thompson 2004.)
