"Their [pedants'] constant overstraining of the Mind / Distorts the Brain, as Horses break their Wind / Or rude Confusions of the Things they read / Get up, like noxious Vapours, in the Head, / Until they have their constant Wanes and Fulls, / And Changes in the Insides of their Skulls."

— Butler, Samuel (1613-1680)

"What fancied zone can circumscribe the Soul, / Who, conscious of the source from whence she springs, / By Reason's light on Resolution's wings, / Spite of her frail / companion, dauntless goes / O'er Libya's deserts and through Zembla's snows? "

— Gray, Thomas (1716-1771)
