Action always involves choice. Man may choose to work, or while away his time in idleness. If man chooses to be idle, he acts, even though his choice results in non-action. The period of non-action will end when another choice is made. When man chooses, he has a goal in mind. He imagines future circumstances. From amongst the imagined futures, he chooses one and acts accordingly. When man acts, he aims at an uncertain future and attempts to achieve circumstances which best suit his desires. The future may be a mere instant from the time of the decision, or many years, decades or even centuries distant. His choice and his action is always aimed at his preferred option. When man acts he may fail to achieve his goal. He may not understand the consequences of his actions. His logic may be flawed. His assumptions may be unsound, but his choice and his action always aims at his preferred future from the possibilities he imagines. Man never acts to deliberately achieve a less palatable option than his most preferred option. If a man chooses to jump off a cliff without a parachute for the sheer thrill of the experience, his choice is not necessarily irrational. He may have some plan for avoiding his death. His goal may be to have a unique thrill and he may be willing to risk his life to achieve this goal. His desire to experience a unique adrenaline rush, fear and exhilaration may be worth more to him than life itself. If he achieves his goal, his future beyond the attainment of the goal may be bleak. Man's actions are only irrational if he knows that his goal cannot be achieved by the methods employed. When man thinks and plans his actions, he may be mistaken. He may mistakenly believe that a certain action will achieve a definite goal. Man does not act in an irrational fashion. When man acts inappropriately, he does so from ignorance or error. An adulterer may choose the momentary satisfaction of his affair over the risk of lengthy costs of divorce and alimony to his spouse. At the moment of the choice, he preferred his mistress to his wife. He preferred to be unfaithful over his solemn vow of fidelity. Prior to the action, he took stock of his circumstances, imagined a future instant and chose the preferred option over a less preferred option. Man’s actions may aim at long or short term goals. His actions may succeed or fail. Action always involves a choice between different, imagined, uncertain, futures. He may regret the choice subsequently, but his action is never irrational. His choice is always to act in such a way, so as to remove some uneasiness in his imagined future. The conclusions which result from the application of observation, reason, logic and passion may be flawed. Even the individual who commits suicide must, at the moment of his action, prefer his death, to an imagined future life. His action is rational, even if his analysis of his life is flawed. It may be argued that the person who commits suicide has erred in his conclusions, but it cannot be argued that his action was irrational. Action defines the individual. It is only when man acts that his true beliefs, preferences and values are demonstrated. Thoughts and statements do not illustrate an individual's value system.
