Final answer:
Screwtape advises Wormwood to keep the patient in contact with superficially successful individuals to divert him from spiritual growth, leading to worldly success but spiritual ruin.
Step-by-step explanation:
In chapter 10 of The Screwtape Letters, Screwtape encourages Wormwood to persuade the patient to maintain his new acquaintances on the grounds of D. Worldly success. Screwtape, the senior demon, believes that by fostering relationships with materialistically successful individuals who lack humility and spiritual depth, the patient may eventually adopt a superficial and cynically smart outlook detached from any true spiritual or moral foundation. He implies that the spiritually shallow yet socially successful crowd will influence the patient to embrace the same values, leading to his eventual spiritual downfall.
