-- Constraint, Compulsion. Constraint implies strong binding force; as, the constraint of necessity; the constraint of fear. Compulsion implies the exertion of some urgent impelling force; as, driven by compulsion. The former prevents us from acting agreeably to our wishes; the latter forces us to act contrary to our will. Compulsion is always produced by some active agent; a constraint may be laid upon us by the forms of civil society, or by other outward circumstances. Crabb.
