The Great Sin

Big idea

Summary

Lewis identifies pride, or self-conceit, as what he calls the 'essential vice' of Christian moral teaching — the sin from which every other sin ultimately grows, and traditionally the sin behind Satan's own fall. He notes a striking asymmetry: people readily confess to bad temper, cowardice, or a weakness for drink, but he has almost never heard anyone outside Christianity accuse themselves of pride, even though everyone instantly recognizes and resents it in other people. This blindness, he suggests, is itself evidence of how deeply pride operates, since the people most infected by it are the least able to see it in themselves.

The chapter's key analytical move is Lewis's claim that pride is uniquely competitive in a way other vices are not. Greed wants more resources, lust wants a particular person, but pride wants only to be above someone else, and is satisfied by nothing except relative superiority — a man already wealthy enough for every comfort may still crave more money purely to outrank a richer rival. Because pride's whole pleasure lies in comparison rather than possession, it can never be permanently satisfied and inevitably produces enmity: anyone who is richer, cleverer, or more powerful automatically becomes a rival.

Lewis then turns to pride's relationship with God, arguing that because God is by definition immeasurably above every person, pride functions as a direct barrier to knowing Him at all — a proud person is always looking down, and so cannot see what is genuinely above. This creates the disturbing possibility of religious pride, in which someone imagines they are humbling themselves before God while actually using that imagined relationship to feel superior to other people; Lewis connects this to Christ's warning that some who prophesied and cast out demons in His name would ultimately be told He never knew them.

The chapter ends with four careful qualifications meant to prevent misunderstanding: pleasure in being rightly praised is not itself pride, only the further step of admiring oneself for having earned it; being 'proud' of a family member or institution can be simple admiration rather than sin; God does not oppose pride out of wounded dignity but because pride blocks the very closeness with Him that He wants to give; and a genuinely humble person will not seem falsely self-deprecating but simply un-self-conscious and interested in others. Lewis closes with the pointed observation that the first and hardest step toward humility is honestly recognizing one's own pride.

Key points

• Pride is called the 'essential vice,' the sin from which Lewis says every other sin ultimately grows.
• Unlike other vices, pride thrives purely on comparison and can never be content, since it always needs someone to be above.
• Money, power, and admiration are often pursued not for their own sake but to outdo others; pride's true reward is power over people.
• Pride creates enmity with other people and, more seriously, with God, since God's superiority over us is absolute.
• Religious pride is possible: mistaking imagined divine approval for humility while quietly despising other people.
• Vanity, which craves others' approval, is a comparatively minor and even 'human' fault beside the cold self-sufficiency of true pride.

Illustrations & analogies

• Lewis describes a man earning ten thousand pounds a year who still wants twenty thousand, not from need but to outrank a wealthier rival, to show pride's true target is power, not comfort.
• He describes a pretty girl who collects admirers out of pride rather than genuine desire, sometimes even while being sexually indifferent to them.
• He compares the devil 'curing' a small vice like vanity by planting the far worse vice of pride to curing chilblains while secretly giving someone cancer.
• He uses the image of stripping off silly 'fancy dress' to describe the relief of losing the false, self-important self in real humility.

Notable lines

That is why I say that Pride is essentially competitive in a way the other vices are not.

For Pride is spiritual cancer: it eats up the very possibility of love, or contentment, or even common sense.

If you think you are not conceited, it means you are very conceited indeed.

For reflection and discussion

1. Lewis claims almost no one outside Christianity ever accuses themselves of pride — does that match your own experience, and why might this particular sin be so hard to see in oneself?
2. How convincing do you find Lewis's argument that pride is 'essentially competitive' in a way greed or lust is not?
3. Lewis warns about a kind of religious pride that hides behind apparent humility toward God — what might that look like in practice today?
