In Morality and Art Mrs Foot characterizes the formalist position about morality as holding ‘that a man can choose for himself, so long as he meets the formal requirements of generality and consistency, what his ultimate moral principles are to be’, and says, quite rightly in my opinion, that it is indefensible, ‘implying as it does that we might recognize as a moral system some entirely pointless set of prohibitions or taboos, or activities such as clapping one's hands, not even thought as harmful, aggressive, treacherous, cowardly by the community in which the prohibitions exist’. Then she adds:
A moral system seems necessarily to be one aimed at removing particular dangers and securing certain benefits, and it would follow that some things do and some do not count as objections to a line of conduct from a moral point of view.
