Syn. -- Decision, Determination, Resolution. Each of these words has two meanings, one implying the act of deciding, determining, or resolving; and the other a habit of mind as to doing. It is in the last sense that the words are here compared. Decision is a cutting short. It implies that several courses of action have been presented to the mind, and that the choice is now finally made. It supposes, therefore, a union of promptitude and energy. Determination is the natural consequence of decision. It is the settling of a thing with a fixed purpose to adhere. Resolution is the necessary result in a mind which is characterized by firmness. It is a spirit which scatters (resolves) all doubt, and is ready to face danger or suffering in carrying out one's determinations. Martin Luther was equally distinguished for his prompt decision, his steadfast determination, and his inflexible resolution. [ 1913 Webster ]
