I see the beauty of Mike's attempt to devise an ideal ethic and applaud his recognition that such must start by junking the present sexual code and starting fresh. Most philosophers haven't the courage for this; they swallow the basics of the present code--monogamy, family pattern, continence, body taboos, conventional restrictions on intercourse, and so forth--then fiddle with details...even such piffle as discussing whether the female breast is an obscene sight!
