On enemy ground
Screwtape twists the gift of pleasure :
Never forget that when we are dealing with any pleasure in it’s healthy and normal and satisfying form, we are, in a sense, on the Enemy’s ground. I know we have one many a soul through pleasure. All the same, it is His invention, not ours. He made all of the pleasures: all our research so far has not been able us to produce one. All we can do is to encourage the humans to take the pleasures which our enemy has produced, at times, or in ways, or in degrees, which he has for bidden. Hence we always try to work away from the natural condition of any pleasure to that and which it is at least natural, least redolent of its Maker, and least pleasurable. An ever increasing craving forever diminishing a pleasure is the formula. It is more certain; and it’s better style. To get the man’s soul and give him nothing in return – that is what really gladdens our father’s heart. And the troughs are the time for beginning the process.
