Abstract

The morality of human actions consists in their reasonableness. An act is reasonable if doing that sort of thing under the circumstances is a reasonable application, in the particular circumstances, of general principles of action which are intelligible and obvious to virtually everyone. Such applications to particular events are conclusions, usually guided by derivative and subordinate principles of natural law and of human law, and do not, therefore, have the certitude of science; in fact, natural law principles occasionally have exceptions. The sphere of human law, narrower than the sphere of natural law which includes the whole field of morality, is the interpersonal actions of men which bear some relation to the common good. Much of human law is an expression of or an application of the moral law. A human law is just only insofar as it is reasonably related to the achievement of the common good, the law has been enacted by a competent legislator and the burdens it imposes are not unreasonably distributed. The system of laws is effective to regulate conduct within society as a whole, not because of the individual’s fear of punishment, but because the society regards the law as a standard for right action.
