Screwtape advises Wormwood /on using time to wear down a soul:
The Enemy has guarded him /from you /through the first great wave of temptations.
But, if only he can be kept alive, you have time itself for your ally.
[The long, dull, monotonous years of middle-aged prosperity or middle-aged adversity are excellent campaigning weather.
You see, it is so hard [for these creatures to persevere].
[The routine of adversity, the gradual decay of youthful loves and youthful hopes],
[the quiet despair (hardly felt as pain) of ever overcoming the chronic temptations
//with which we have again and again defeated them],
[the drabness //which we create in their lives and the inarticulate resentment //with which we teach them to respond to it]
—[all this] provides admirable opportunities of wearing out a soul by attrition.
* [all this] = [The routine...], [the quiet despair...], [the drabness... and the inarticulate...]
If, on the other hand, the middle years prove prosperous, our position is even stronger.
Prosperity knits a man to the World.
He feels that he is ‘finding his place in it’, while really it is finding its place in him.
* it = the World
His increasing reputation, his widening circle of acquaintances, his sense of importance,
the growing pressure of absorbing and agreeable work,
build up/ in him [a sense of being really at home in earth], which is just [what we want].
You will notice that the young are generally less unwilling /to die /than the middle- aged and the old.
