A fisherman, putting his hand hastily into his net, was wounded by the thorns on the backs of some of the fish; being thus caught, he said, I shall now become wiser: which is said to have given rise to the adage. "Bought wit," we say," is best;" it will certainly be more likely to be remembered, than that which is obtained without suffering some kind of loss or inconvenience. Hence also we say, "wit once bought, is worth twice taught." "El hombre mancebo, perdiendo gana seso," by losses and disappointment young men acquire knowledge.
