But the result of the examination was to bring out with fresh force and vividness the difference between the maxims of Common Sense Morality (even the strongest and strictest, _e.g._ Veracity and Good Faith) and the intuitions which I had already attained, _i.e._ the Kantian Principle (of which I now saw the only certain element in Justice--“treat similar cases similarly”--to be a particular application), and the Fundamental Principle of Utilitarianism. And this latter was in perfect harmony with the Kantian Principle. I certainly could will it to be a universal law that men should act in such a way as to promote universal happiness; in fact it was the only law that it was perfectly clear to me that I could thus decisively will, from a universal point of view. I was then a Utilitarian again, but on an Intuitional basis. But further, the reflection on Common Sense Morality which I had gone through, had continually brought home to me its character as a system of rules tending to the promotion of general happiness (cf. [_Methods of Ethics_] pp. 470, 471). Also the previous reflection on hedonistic method for Book ii. had shown me its weaknesses. What was then to be done? [The] conservative attitude [to be observed] towards Common Sense [is] given in chapter v. of Book iv.: “Adhere generally, deviate and attempt reform only in exceptional cases in which,--notwithstanding the roughness of hedonistic method,--the argument against Common Sense is decisive.” In this state of mind I published my book: I tried to say what I had found: that the opposition between Utilitarianism and Intuitionism was due to a misunderstanding. There was indeed a fundamental opposition between the individual’s interest and either morality, which I could not solve by any method I had yet found trustworthy, without the assumption of the moral government of the world: so far I agreed with both Butler and Kant. But I could find no real opposition between Intuitionism and Utilitarianism.... The Utilitarianism of Mill and Bentham seemed to me to want a basis: that basis could only be supplied by a fundamental intuition; on the other hand the best examination I could make of the Morality of Common Sense showed me no clear and self-evident principles except such as were perfectly consistent with Utilitarianism.
