An act or action is a voluntary exercise of any power of body or mind. The character of an action, whether good or bad, depends on the intention of the agent. Thus, if I mean to do my neighbor a kindness by any particular act, the action is kind, and therefore good, on my part, even though he derive no benefit from it, or be injured by it. If I mean to do my neighbor an injury, the action is unkind, and therefore bad, though it do him no harm, or though it even result to his benefit. If I mean to perform an action, good or bad, and am prevented from performing it by some unforeseen hindrance, the act is as truly mine as if I had performed it. Words which have any meaning are actions. So are thoughts which we purposely call up, or retain in the mind.
