Men who have flattered themselves into this opinion of their own abilities, look down on all who waste their lives over books, as a race of inferior beings condemned by nature to perpetual pupilage, and fruitlessly endeavouring to remedy their barrenness by incessant cultivation, or succour their feebleness by subsidiary strength. They presume that none would be more industrious than they, if they were not more sensible of deficiences; and readily conclude, that he who places no confidence in his own powers owes his modesty only to his weakness.
Samuel JohnsonIt is not often that any man can have so much knowledge of another, as is necessary to make instruction useful.
Samuel Johnson
