You can argue truly enough, for example, that general respect for the prohibition on murder makes life more commodious. If people really respect the … - G. E. M. Anscombe

The denial of any distinction between foreseen and intended consequences, as far as responsibility is concerned, was not made by Sidgwick in developing any one 'method of ethics'; he made this important move on behalf of everybody and just on its own account; and I think it plausible to suggest that this move on the part of Sidgwick explains the difference between old-fashioned Utilitarianism and the consequentialism, as I name it, which marks him and every English academic moral philosopher since him.

A severe morality holds that intercourse (and may hold this of eating, too) has something wrong about it if it is ever done except explicitly as being required for that preservation of human life which is what makes intercourse a good kind of action. But this involves thoroughly faulty moral psychology. God gave us our physical appetite, and its arousal without our calculation is part of the working of our sort of life. Given moderation and right circumstances, acts prompted by inclination can be taken in a general way to accomplish what makes them good in kind and there's no need for them to be individually necessary or useful for the end that makes them good kinds of action. Intercourse is a normal part of married life through the whole life of the partners in a marriage and is normally engaged in without any distinct purpose other than to have it, just as such a part of married life.

The trouble about the Christian standard of chastity is that it isn't and never has been generally lived by; not that it would be profitless if it were. Quite the contrary: it would be colossally productive of earthly happiness. All the same it is a virtue, not like temperance in eating and drinking, not like honesty about property, for these have a purely utilitarian justification. But it, like the respect for life, is a supra-utilitarian value, connected with the substance of life, and this is what comes out in the perception that the life of lust is one in which we dishonour our bodies. Implicitly, lasciviousness is over and over again treated as hateful, even by those who would dislike such an explicit judgment on it. Just listen, witness the scurrility when it's hinted at; disgust when it's portrayed as the stuff of life; shame when it's exposed, the leer of complicity when it's approved. You don't get these attitudes with everybody all of the time; but you do get them with everybody. (It's much too hard work to keep up the façade of the Playboy philosophy, according to which all this is just an unfortunate mistake, to be replaced by healthy-minded wholehearted praise of sexual fun.)
