at the back of the mind

Muse poetry is composed at the back of the mind: an unaccountable product of a trance in which the emotions of love, fear, anger, or grief are profoundly engaged, though at the same time powerfully disciplined; in which intuitive thought reigns supralogically, and personal rhythm subdues metre to its purposes. The effect on the readers of Muse poetry, which its opposite poles of ecstasy and melancholia, is what the French call a frisson, and the Scots call a ‘grue’—meaning the shudder provoked by fearful or supernatural experiences.
