Abstract
Desires are natural inclinations, hard to change, to do certain actions or allow certain events to occur. Enjoyment consists in the believed satisfaction of present desire. We always act on our strongest desires, unless we have good reason for not doing so and then we have to choose between reason and desire. Weakness of will consists in yielding to desire when reason suggests that we should not do so. Modification of desire is distinguished from forming an intention for the future, which in turn is distinguished from having an intention in one's present actions.
