Secondly there is thought proper, when the power of the will is directing the activity of the mind. This explains the words "thoughtful" and "thoughtless." The thoughtful person is he whose will directs his mind, whether he is doing something or speaking or thinking. It is he whom people will call a thinker. But the one who does not control his action, speech, and thoughts by his will is thoughtless; his thought is really imagination, his speech does not make sense, his actions become thoughtless and inconsiderate. In brief, these three things--thought, speech, and action--reveal the character of the thought. If they are controlled by the will they show thoughtfulness, but if they are not so controlled the person is called thoughtless.
