“A learned man is a sedentary, concentrated solitary enthusiast, who searches through books to discover some particular grain of truth upon which he has set his heart. If the passion for reading conquers him, his gains dwindle and vanish between his fingers. A reader, on the other hand, must check the desire for learning at the outset; if knowledge sticks to him well and good, but to go in pursuit of it, to read on a system, to become a specialist or an authority, is very apt to kill what suits us to consider the more humane passion for pure and disinterested reading.”
