  Such reflection quickly reveals the extent to which various aspects of morality might reasonably be seen as both intellectually and practically problematic. On the intellectual side, many have worried that there is no good way to vindicate the assumptions and commitments of morality. A careful and clear-eyed study of morality will reveal, some argue, that morality is a myth; others argue that the various principles that are presented as authoritative standards for all are actually merely expressions of emotion or projections of the idiosyncratic attitudes of those advocating the principles; still others argue that in some other way morality is not what it pretends to be and not what it needs to be if it is to be legitimate. On the practical side, many have pressed the difficulty of getting people to judge themselves and others impartially; others have worried that, while we have an interest in convincing others to conform to morality, we ourselves rarely have any reason, really, to conform; still others have thought that the sort of freedom morality assumes is not available to humans as they actually are.
