Hence nearly all vices are rooted in the future. Gratitude looks to the past and love to the present; fear, avarice, lust, and ambition look ahead. Do not think lust an exception. When the present pleasure arrives, the sin (which alone interests us) is already over. The pleasure is just the part of the process which we regret and would exclude if we could do so without losing the sin; it is the part contributed by the Enemy, and therefore experienced in a Present. The sin, which is our contribution, looked forward.
