I say that conceit is just as natural a thing to human minds as a centre is to a circle. But little-minded people’s thoughts move in such small circles that five minutes’ conversation gives you an arc long enough to determine their whole curve. An arc in the movement of a large intellect does not sensibly differ from a straight line. Even if it have the third vowel [‘I’, the first-person pronoun] as its centre, it does not soon betray it. The highest thought, that is, is the most seemingly impersonal; it does not obviously imply any individual centre.
