The Benthamic standard of “the greatest happiness†was that which I had always been taught to apply; I was even familiar with an abstract discussion of it, forming an episode in an unpublished dialogue on Government, written by my father on the Platonic model. Yet in the first pages of Bentham it burst upon me with all the force of novelty. What thus impressed me was the chapter in which Bentham passed judgment on the common modes of reasoning in morals and legislation, deduced from phrases like “law of nature,†“right reason,†“the moral sense,†“natural rectitude,†and the like, and characterized them as dogmatism in disguise, imposing its sentiments upon others under cover of sounding expressions which convey no reason for the sentiment, but set up the sentiment as its own reason. It had not struck me before, that Bentham’s principle put an end to all this. The feeling rushed upon me, that all previous moralists were superseded, and that here indeed was the commencement of a new era in thought.
