Context

“The goods of fortune we would possess and would enjoy; those of virtue we long to practice and exercise; we are content to receive the former from others, the latter we wish others to experience from us. Moral good is a practical stimulus; it is no sooner seen, than it inspires an impulse to practice; and influences the mind and character not by a mere imitation which we look at, but, by the statement of the fact, creates a moral purpose which we form. And so we have thought fit to spend our time and pains in writing of the lives of famous persons;” source
