Constrained

Human madness is oftentimes a cunning and most feline thing. When you think it fled, it may have but become transfigured into some still subtler form. Ahab’s full lunacy subsided not, but deepeningly contracted; like the unabated Hudson, when that noble Northman flows narrowly, but unfathomably through the Highland gorge. But, as in his narrow-flowing monomania, not one jot of Ahab’s broad madness had been left behind; so in that broad madness, not one jot of his great natural intellect had perished.
