Everything that serves to preserve the social order is moral; everything that is detrimental to it is immoral. Accordingly, when we reach the conclusion that an institution is beneficial to society, one can no longer object that it is immoral. There may possibly be a difference of opinion about whether a particular institution is socially beneficial or harmful. But once it has been judged beneficial, one can no longer contend that, for some inexplicable reason, it must be condemned as immoral.
