The man who has performed no single action of importance, but whose whole conversation and deportment express the justest, the noblest, and most generous sentiments, can be entitled to demand no very high reward, even though his inutility should be owing to nothing but the want of an opportunity to serve.

Context

“He is made to know, that the praise of good intentions, without the merit of good offices, will be but of little avail to excite either the loudest acclamations of the world, or even the highest degree of self-applause. The man who has performed no single action of importance, but whose whole conversation and deportment express the justest, the noblest, and most generous sentiments, can be entitled to demand no very high reward, even though his inutility should be owing to nothing but the want of an opportunity to serve. We can still refuse it him without blame. We can still ask him, What have you done? What actual service can you produce, to entitle you to so great a recompense? We esteem you, and love you; but we owe you nothing.” source
