Did life's penurious length — Summary

Dickinson imagines what would happen if the shortness of life actually made us feel its sweetness more sharply. In her hands, this isn’t a sentimental thought; it’s a mechanical near-disaster. If we really stood “so deep in joy,” the pure intensity would gum up the works of reason. She pictures our rational mind as a kind of engine, with an odd, hidden belt that keeps us ticking over normally. Too much joy would stop those gears. The speaker isn’t exactly lamenting this — there’s a cool, almost teasing detachment in the way she warns that our sanity depends on not feeling life’s beauty too fully. The mood is paradoxical and lightly unsettling: it suggests that being utterly happy would undo us, and so we’re protected by a necessary dullness. It’s a strange comfort, and very Dickinson in its mix of abstract machinery and enormous feeling.
