For there exists a great chasm between those, on one side, who relate everything to a single central vision, one system, less or more coherent or articulate, in terms of which they understand, think and feel - a single, universal, organising principle in terms of which alone all that they are and say has significance - and, on the other side, those who pursue many ends, often unrelated and even contradictory, connected, if at all, only in de facto way for some psychological or physiological cause, related to no moral or aesthetic principle. This last lead lives, perform acts and entertain ideas that are centrifugal rather than centripetal; their thought is scattered or diffused, moving on many levels, seizing upon the essence of a vast variety of experiences and objects; for they are themselves, consciously or unconsciously seeking to fit them into or exclude them from any one unchanging, all-embracing, sometimes self-contradictory and incomplete at times fanatical, military inner vision. The first kind of intellectual and artistic personality belongs to the hedgehogs, the second to the foxes.
