 Foot came to this mixed view from the direction of objectivism (in the form of a virtue theory), and it might be contended by some objectivists that she has conceded too much. Since there are objective criteria, what appear as rationally irresolvable disagreements might be resolvable through greater understanding of human nature. Or the objective criteria might establish that in some limited cases it is an objective moral truth that conflicting moral practices are both morally permissible. In view of such considerations, objectivists might argue, it is not necessary to have recourse to the otherwise problematic notion of relative moral truth.
