 These qualifications and limitations then invariably involve a discussion of the case for socialism and/or communism, a subject that Sidgwick addressed at length in many works. His main objection to socialistic interference was the familiar one that too much of it would lead to splendidly equal destitution, as the old line has it, and that for people as presently constituted economic incentives were needed to spur them to produce. But again, he hoped that “human nature” would change, growing more sympathetic and more amenable to ethical socialism, leaving the door open to the possibility of legitimating greater governmental interference with the market.
