The Marriage of Heaven and Hell (1790-3) 'Proverbs of Hell'

William Blake

He who desires but acts not, breeds pestilence.

Behind the line

What it means

Our interpretation.

The proverb compares desire without action to the breeding of disease. That severe metaphor makes passivity sound corrosive rather than harmless. Read as a challenge to frustrated longing, it urges a connection between wanting and doing, without specifying what action would be appropriate.
