He who acts under an emotional impulse also acts. What distinguishes an emotional action from other actions is the valuation of input and output. Emotions disarrange valuations. Inflamed with passion, man sees the goal as more desirable and the price he has to pay for it as less burdensome than he would in cool deliberation.
Ludwig von MisesThe alcoholic and the drug addict harm only themselves by their behavior; the person who violates the rules of morality governing mans life in society harms not only himself, but everyone.
