Earth

Earth is both the changing habitat of human life and the setting in which its spiritual direction is tested. In the letters, Screwtape repeatedly describes the world as a place where people may be made to feel at home and where the Devils hope to loosen their attachment to Heaven. Yet the account’s central irony is that life on Earth, precisely because it is finite and changeable, can also teach people to choose good without the emotional rewards that once made it easy. The claims about this struggle come from a devilish correspondent whom the book’s prefatory warning explicitly identifies as a liar, so his explanations reveal infernal assumptions as much as they describe human life.

A Temporal and Embodied World

Humans inhabit Earth as creatures divided between spirit and animal nature. Their spirits belong to eternity, while their bodies, passions, and imaginations undergo continual change because they live in time. Screwtape describes this instability as an undulation: interests, affections, appetites, and emotional energy rise to peaks and sink into troughs. Earthly experience is therefore neither steadily pleasurable nor spiritually uniform; richness and liveliness alternate with numbness and dryness.

That fluctuation gives earthly life a particular spiritual significance. A period of emotional dryness is not necessarily evidence that the Devils have succeeded. Screwtape concedes that such troughs are a natural feature of human existence, and that God may use them more deeply than moments of spiritual sweetness. When sensible consolation recedes, a person may have to continue duties through the will alone. Earth is thus the arena in which attachment to the good can become more than a response to agreeable feeling: the choice to persist when virtue has lost its relish matters precisely because life remains uncertain and changeable.

Earth, Eternity, and the Present

Earthly life unfolds in time, but the letters distinguish attention to the present from absorption in an imagined future. The present moment is where human beings actually encounter freedom and action: they can answer conscience, bear a current burden, receive grace, or give thanks for pleasure as it arrives. The future, by contrast, is unknown, and fixating on it can turn hope and fear into preoccupation with unrealities. Screwtape’s strategy is to pull people away both from eternity and from the present, leaving them to live in anticipation.

This distinction does not condemn practical planning. A person may plan tomorrow’s work of justice or charity, but the planning itself is a duty performed today; the future need not become the object of the heart. The infernal preference is for a person haunted by promises of a transformed earthly future, willing to neglect present kindness or obedience in pursuit of a remote outcome. In that scheme, actual gifts in the present become fuel for an imagined future that may never arrive. Earth’s spiritual contest is therefore not a simple choice between worldly action and religious withdrawal: it concerns whether action is undertaken as a present duty or sacrificed to an attempt to possess what has not yet come.

Competing Ways of Belonging

Screwtape’s account of the infernal order casts existence itself as competition. On this view, one being’s gain must be another’s loss; a stronger self expands by displacing, absorbing, or controlling a weaker one. Earthly life supplies the Devils with opportunities to make that logic seem natural, and they understand human beings as potential food whose wills can be drawn into their own. Their ideal is absorption: the individual’s freedom diminishes as infernal selfhood grows.

The opposing account, which Screwtape presents with undisguised hostility, imagines unity without erasing distinct persons. God seeks beings whose wills freely conform to his, not creatures whose identities have been swallowed. The contrast is expressed as cattle destined to become food against servants who may become sons, and as an empty power that wants to be filled against a fullness that gives out. Earth matters within this opposition because human lives take place among distinct bodies and relationships, where the difference between controlling another and loving another can be enacted. Screwtape’s inability to make love intelligible within his competitive assumptions exposes the limits of his own explanation rather than disproving the love he insists cannot exist.

Attachment, Work, and the Risk of Feeling at Home

The Devils regard time as a strategic resource because an earthly life may give them years in which to encourage attachment to the world. Screwtape argues that seventy years would not be excessive for gradually loosening a person’s ties to Heaven. Youth, he says, is difficult for infernal purposes: imagination, music, poetry, a girl’s face, a bird’s song, or a horizon can turn attention away from cautious worldly advancement. Over time, however, worldly habits may be praised as maturity or experience, while the slow loss of spiritual responsiveness passes for good sense.

Middle age offers a different danger in either prosperity or adversity. In adversity, chronic temptation, drab routines, fading youthful hopes, and quiet resentment may wear down a person by attrition. In prosperity, reputation, a widening circle of acquaintances, and absorbing work can make the world feel like home. Screwtape’s image reverses the apparent direction of belonging: a person thinks he is finding his place in the world, while the world is finding its place in him. These are not claims that work, relationships, or earthly well-being are inherently evil; they describe how such goods can be made into instruments of attachment when they displace the person’s orientation toward Heaven.

The book also places this struggle within wartime Earth without treating the war’s history as its main subject. Its preface says that the European War matters to Screwtape only when it affects one human being’s spiritual condition. As the war approaches, the patient’s worldly hopes recede while defence work, love, service to neighbours, and conscious dependence on God occupy more of his life. Screwtape consequently wants him kept bodily safe: survival would leave time for the slower work of making Earth feel more securely like home. The contrast makes earthly safety morally complicated within the correspondence. Survival can extend the Devils’ opportunity, while the patient’s present service and dependence already threaten their hold.

The World as Provisional Home

Screwtape’s longest strategy is to make Earth seem sufficient. Since, in his account, most human beings die in infancy and many survivors die young, the Devils can work only on a minority long enough to attempt a gradual redirection of their lives. He complains that people are not naturally steady in worldly ambition and suggests that they may be persuaded to imagine Earth becoming a future heaven through politics, eugenics, science, or psychology. The promise of a perfected world can thus serve as a substitute for attention to eternity, especially when it makes the present merely preparatory.

The conclusion overturns the premise that earthly life is the final measure of a person’s good. In the patient’s death, Screwtape confronts the fact that what he calls an animal of Earth can enter the presence of God. The patient’s bodily life ends, but his earthly history is disclosed as having included a reality that exceeded his conscious understanding: he recognizes the spiritual companions who had been present through many earlier moments and sees God not as a terror but as clarity. Earth is consequently neither the Devils’ permanent home for their prey nor a self-sufficient destination. It is a temporary, embodied life whose changing circumstances can be exploited to foster attachment to the world, yet whose present acts and relationships can also prepare a person for a life beyond it.
