George Orwell, "The Art of Donald McGill," Horizon
[T]wo principles, noble folly and base wisdom, exist side by side in nearly every human being. If you look into your own mind, which are you, Don Quixote or Sancho Panza? Almost certainly you are both. There is one part of you that wishes to be a hero or a saint, but another part of you is a little fat man who sees very clearly the advantages of staying alive with a whole skin. He is your unofficial self, the voice of the belly protesting against the soul. His tastes lie towards safety, soft beds, no work, pots of beer and women with 'voluptuous' figures. He it is who punctures your fine attitudes and urges you to look after Number One, to be unfaithful to your wife, to bilk your debts, and so on and so forth. Whether you allow yourself to be influenced by him is a different question. But it is simply a lie to say that he is not part of you, just as it is a lie to say that Don Quixote is not part of you either, though most of what is said and written consists of one lie or the other, usually the first.
