Sidgwick gives various tests for highest certainty. When he applies these tests to commonsense morality, he finds nothing of highest certainty. In contrast, when he applies these tests to his own axioms, he finds these axioms to have highest certainty. The axioms culminate in Benevolence: “Each one is morally bound to regard the good of any other individual as much as his own, except in so far as he judges it to be less, when impartially viewed, or less certainly knowable (...) or attainable by him.” The axioms face challenges from two sides.First, one test requires that a claim not be denied by someone of whom one has no more reason to suspect of error than oneself. For Sidgwick, then, the egoist must not deny the axioms. But it would seem that an egoist would reject benevolence. Second, Sidgwick thinks he must show that the commonsense moralist agrees to the axioms. Benevolence seems to say that the only reason for departing from being bound to treat others like oneself is that more good would be produced. But the commonsense moralist will not agree that this is the only reason. In reply to the threat of an egoist's disagreement, this essay argues that many of the axioms should be read as having as their antecedent “from the point of view of the universe.” The essay replies to the objection that this makes these axioms analytic. In reply to the threat of a commonsense moralist's disagreement, this essay argues that each axiom states, in effect, a prima facie duty. The argument against the commonsense moralist concerns not benevolence but whether there are further duties that pass the tests. The essay raises the worry that here Sidgwick is unfair since sometimes he criticizes all-things-considered versions of commonsense duties; such criticisms would count against benevolence as well.

Sidgwick saw egoism as important and undefeated. Not long afterward, egoism is largely ignored. Immediately after Sidgwick, many arguments were given against egoism – most poor – but one argument deserves attention as both influential and plausible. Call it the “grounds objection.” It has two strands. It objects that there are justifying reasons for action other than that an action will maximize my self-interest. It also objects that sometimes, what makes an action right is a fact other than its maximizing (...) my self-interest. I briefly explain and criticize many of the arguments given against egoism in the period, then explain and defend the grounds objection. (shrink)

I suggest that Sidgwick, in his controversial “distinction passage,” has Schopenhauer in mind as someone who denies egoism on the ground that there are no separate individuals. I then reconstruct Sidgwick's argument in the passage. I take him to be defending a presupposition of the case for choosing egoism over utilitarianism. He is claiming that there are separate individuals. I close by rejecting alternative interpretations, on which Sidgwick is arguing directly for egoism.

InThe Methods of EthicsHenry Sidgwick argued against deontology and for consequentialism. More specifically, he stated four conditions for self-evident moral truth and argued that, whereas no deontological principles satisfy all four conditions, the principles that generate consequentialism do. This article argues that both his critique of deontology and his defence of consequentialism fail, largely for the same reason: that he did not clearly grasp the concept W. D. Ross later introduced of a prima facie duty or duty other things equal. (...) The moderate deontology Ross's concept allows avoids many of Sidgwick's objections. And Sidgwick's statements of his own axioms equivocate in exactly the same way for which he criticized deontological ones. Only if they are read as other things equal can they seem intuitive and earn widespread agreement; but that form is too weak to ground consequentialism. And in the form that does yield consequentialism they are neither intuitive nor widely accepted. Sidgwick's arguments against a rival view and for his own were, in multiple ways, unfair. (shrink)
