Excess Learning without understanding may induce brain farts.
Of knowledge within bounds; beyond abstain [ 120 ]
Anough is left besides to search and know. [ 125 ]
But Knowledge is as food, and needs no less
Her Temperance over Appetite, to know
In measure what the mind may well contain,
Oppresses else with Surfet, and soon turns
Wisdom to Folly, as Nourishment to Winde. [ 130 ]
(Paradise Lost, John Milton, Book VII)
(It seams even John Milton has a sense of humour.)
Surfet > Surfeit;
Excess; specifically (and now usually), excess in eating and drinking; a gluttonous meal by which the stomach is overloaded and the digestion deranged.
