"A creature can never be a perfect being, but may be a perfect creature — e.g. a good angel or a good apple-tree. Gaiety at its highest may be an (intellectual) creature’s delighted recognition that its imperfection as a being may constitute part of its perfection as an element in the whole hierarchical order of creation. I mean, while it is a pity there should be bad men or bad dogs, part of the excellence of a good man is that he is not an angel, and of a good dog that it is not a man. This is the extension of what St. Paul says about the body & the members. A good toe-nail is not an unsuccessful attempt at a hair; and if it were conscious it would delight in being simply a good toe-nail."
- CS Lewis
