The man who restraineth his active faculties, and sitteth down with his mind attentive to the objects of his senses, is called one of an astrayed soul, and the practiser of deceit. So the man is praised, who, having subdued all his passions, performeth with his active faculties all the functions of life, unconcerned about the event.
 Henry David Thoreau, A Week on the Concord and Merrimack Rivers (1849). copy citation

Every man is involuntarily urged to act by those principles which are inherent in his nature.

So the man is praised, who, having subdued all his passions, performeth with his active faculties all the functions of life, unconcerned about the event.” “Let the motive be in the deed and not in the event. Be not one whose motive for action is the hope of reward. Let not thy life be spent in inaction.” “For the man who doeth that which he hath to do, without affection, obtaineth the Supreme.”” source
