The secret of poetry is never explained - is always new. We have not got farther than mere wonder at the delicacy of the touch, & the eternity it inherits. In every house a child that in mere play utters oracles, & knows not that they are such. 'Tis as easy as breath. 'Tis like this gravity, which holds the Universe together, & none knows what it is.
