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, organizing principle in terms of which all that they are and say has signficance - and, on the other side, those who pursue many ends, often unrelated and even contradictory (...) ; these last lead lives, perform acts, and entertain ideas that are centrifugal rather than centripetal, their thought is scattered or diffused, moving on many levels, (...) without conciously or unconciously seeking to fit them into or exclude them from any one unchanging... at times fanatical, unitary inner vision.
