Ethical formalism is a type of ethical theory which efines moral judgements in terms of their logical form (e.g., as "laws" or "universal prescriptions") rather than their content (e.g., as judgements about what actions will best promote human well-being). The term also often carries critical connotations. Kant, for example, has been criticized for defining morality in terms of the formal feature of being a "universal law", and then attempting to derive from this formal feature various concrete moral duties.
