This depends upon there being a brain, an arrangement of cells in a particular part of the body which by reason of its peculiar coordination makes the given routing able to «know» in a distinctively human manner — quite different from, although certainly continuous with, the sort of «knowing» that is possible for the higher grades of animal life.

The building block electronic and protonic actual occasions are, in the case of human beings, swept into vastly more complex, Chinese box - like sets of containing societies within which there are social levels that can be identified with cells, others which answer to Aristotle's levels of tissues and organs, and which finally are presided over by what Whitehead refers to as the regnant nexus, a social thread of complex temporal inheritance which, Whitehead suggests, wanders from part to part of the brain, is the seat of conscious direction of the organism as a whole, and answers to what in Plato and Aristotle is called the soul.

No doubt it is true, scientifically speaking, that no distinct center of superhuman consciousness has yet appeared on earth (at least in the living world) for which it may be claimed or predicted that one day it will exercise a centralizing function, in relation to associated human thought, similar to the role of the individual «I» in relation to the cells of the brain.
