Such accidents as these ought to admonish us not to be too prodigal of our virtue, nor inconsiderately to prostitute our perfections to the enjoyment of every little thing that pretends to be our humble admirer; rather let us reserve them for the worthy, for those who can love and share another’s joys and sorrows like ourselves. And truly, this alone renders it most unlikely that many men should remain friends, that real friendship has always its origin from likeness. For, we may observe, even brute and inanimate beings affect their like, very readily mixing and uniting with those of their own nature; while with great reluctance and a kind of indignation they shrink from and avoid whatever differs from themselves, and force can scarce oblige them to the loathed embraces. By what motive then can we imagine any league of amity can be kept inviolable amidst a multitude, where manners admit of so much variety, where desires and humors will be perpetually jarring, where the several courses of life must needs be almost as unlike as constitutions and faces? A musical concord consists of contrary sounds, and a due composition of flat and sharp notes makes a delightful tune; but as for friendship, that is a sort of harmony all of a piece, and admits not the least inequality, unlikeness, or discords of parts, but here all discourses, opinions, inclinations, and designs serve one common interest, as if several bodies were acted and informed by the same soul.
