Умные мысли

[KD]

The self-taught man seldom knows anything accurately, and he does not know a tenth as much as he could have known if he had worked under teachers; and, besides, he brags, and is the means of fooling other thoughtless people into going and doing as he himself has done.

Самоучка редко знает что-нибудь как следует и обычно в десять раз меньше, чем узнал бы с учителем; кроме того, он любит хвастаться и вводить в соблазн других легкомысленных людей.

Марк Твен "Укрощение велосипеда".
