Letters to Sir William Windham and Mr. Pope

You have begun your ethic epistles in a masterly manner. You have copied no other writer, nor will you, I think, be copied by any one. It is with genius as it is with beauty; there are a thousand pretty things that charm alike; but superior genius, like superior beauty, has always something particular, something that belongs to itself alone. It is always distinguishable, not only from those who have no claim to excellence, but even from those who excel, when any such there are.
