No man, however enslaved to his appetites, or hurried by his passions, can, while he preserves his intellects unimpaired, please himself with promoting the corruption of others. He whose merit has enlarged his influence would surely wish to exert it for the benefit of mankind. Yet such will be the effect of his reputation, while he suffers himself to indulge in any favourite fault, that they who have no hope to reach his excellence will catch at his failings, and his virtues will be cited to justify the copiers of his vices.
Samuel Johnson
