This title calls for an examination of political intervention in a certain field from the viewpoint of ethics. Social action can mean action by a social group or action for a social group or action both by and for a social group. Most frequently the term is used to designate action or activities for social groups which are in some kind of need. The need is not always physical nor does it always imply a degree of want equivalent to destitution. The needy social group may require education rather than physical sustenance and it may already be in possession of a decent minimum of living. “Political intervention” means activity by the state whether the intervention be legislative, administrative or judicial. “Ethics” means ethical principles rather than an ethical treatise. As a code of principles and rules ethics has quite as direct an application to political actions as to the actions of individuals. In other words, a given instance of political intervention in the field of social action is either right or wrong. And the test or criterion of right and wrong is found in man's rational nature, adequately considered; that is, in his constitution and essential relations. From this formulation it is possible to derive all the particular rules of right conduct and the appropriate judgments upon the moraliy of particular actions.
