Moral relativists often defend their view as an inference to the best explanation of widespread and deep moral disagreement. Many philosophers have challenged this line of reasoning in recent years, arguing that moral objectivism provides us with ample resources to develop an equally or more plausible method of explanation. One of the most promising of these objectivist methods is what I call the self-interest explanation, the view that intractable moral diversity is due to the distorting effects of our interests. In (...) this paper I examine the self-interest explanation through the lens of the famine debate, a well-known disagreement over whether we have a moral obligation to donate most of our income to the global poor. I argue that objectivists should reduce their confidence that the persistence of the famine debate is due to the distorting influence of self-interest. If my argument is on target, then objectivists may need to supply a stronger explanation of moral disagreement to defend their view against the threat of moral relativism. (shrink)

Moral judgments entail or consist in claims that certain ways of behaving are called for. These actions have expectable consequences. I will argue that these consequences are suspiciously benign: on controversial issues, each side assesses these consequences, measured in dispute-independent goods, as significantly better than the consequences of behaving in the ways their opponents recommend. This remains the case even when we have not formed our moral judgment by assessing consequences. I will suggest that the evidence indicates that our perception (...) of the consequences of acting as recommended by our moral judgments is motivated, such that the warrant of such assessments is lower than we might have thought. The suspicion correlation between our moral judgments and our assessments of the implicated facts provides higher-order evidence that should lead us to reduce our confidence in these assessments.
