Public morality refers to moral and ethical standards enforced in a society, by law or police work or social pressure, and applied to public life, to the content of the media, and to conduct in public places. A famous remark of Mrs Patrick Campbell, that she did not care what people did as long as they "didn't frighten the horses", shows that in some sense even high tolerance expects a public limitation on behaviour. At the opposite extreme a theocracy may equate public morality with religious instruction, and give both the equal force of law.
