 Sometimes, Bentham appears to allow for a more diverse set of ultimate motives or interests, including other-regarding motives (Principles X 25, X 36–38, XI 31; Table of the Springs of Action II 2). But these concessions to psychological pluralism are exceptional. Even in contexts where Bentham recognizes motivation that is not ultimately self-interested, he appears to treat it as weaker and less dependable than self-interested motivation (Book of Fallacies 392–93).
