Desire-satisfaction and Welfare as Temporal

Welfare is at least occasionally a temporal phenomenon: welfare benefits befall me at certain times. But this fact seems to present a problem for a desire-satisfaction view. Assume that I desire, at 10am, January 12th, 2010, to climb Mount Everest sometime during 2012. Also assume, however, that during 2011, my desires undergo a shift: I no longer desire to climb Mount Everest during 2012. In fact, I develop an aversion to so doing. Imagine, however, that despite my aversion, I am forced to climb Mount Everest. Does climbing Mount Everest benefit me? If so, when? A natural answer seems to be that if in fact it does benefit me, it benefits me at no particular time, and hence the desire-satisfaction view cannot accommodate the phenomenon of temporal welfare. In this paper, I argue, first, that a desire-satisfaction view can accommodate the phenomenon of temporal welfare only by accepting what I call the time-of-desire view: that p benefits x at t only if x desires p at t. Second, I argue that this view can be defended from important objections.
