"Let’s assume that pleasure is a kind of feeling. So how can it be distinguished from desire? Desire is forever constructing a future out of the present. Desire that finds satisfaction is annhilated; yet it always seeks its own destruction by picturing a satisfied future in which it will no longer exist. Pleasure, on the other hand, is contained within the present, and would completely stop the movement of horizontal time, if it could. It may occur sponatneously, without first having been desired. It is a harmonious state, whereas desire is dissonant. In some cases pleasure ensues when desire is satsified, “all passion spent.” But desire just as often engenders nothing but more desire, unavoidably followed by one of two displeasures: satiety or frustration."
