Blake’s speaker makes a startling claim: Pity and Mercy only exist because we ensure someone is poor or unhappy. Peace, too, is just a ceasefire born from mutual fear, and as selfish loves swell, Cruelty sets out snares with care. From this corrupted soil, a tree emerges—watered with holy tears, its root a Humility that lies crushed underfoot. Soon the dismal shade of Mystery spreads overhead, and caterpillars and flies feed on it. The tree’s fruit is Deceit, ruddy and sweet, and a raven nests in its thickest shade. The gods searched all of nature and found nothing—this tree grows solely in the human brain. The poem feels like a chillingly calm unmasking of how our virtues can hide selfishness and cruelty. Its mood is dark, claustrophobic, as if the speaker is leading you through a mental wilderness where familiar moral comforts turn eerie and untrustworthy.
The Human Abstract — Summary
Pity would be no more If we did not make somebody poor, And Mercy no more could be If all were as happy as we.
And mutual fear brings Peace, Till the selfish loves increase; Then Cruelty knits a snare, And spreads his baits with care.
He sits down with his holy fears, And waters the ground with tears; Then Humility takes its root Underneath his foot.
Soon spreads the dismal shade Of Mystery over his head, And the caterpillar and fly Feed on the Mystery.
And it bears the fruit of Deceit, Ruddy and sweet to eat, And the raven his nest has made In its thickest shade.
The gods of the earth and sea Sought through nature to find this tree, But their search was all in vain: There grows one in the human Brain.
