[A]s followers of natural science we know nothing of any relation between thoughts and the brain, except as a gross correlation in time and space. - Charles Scott Sherrington

In the great head-end which has been mostly darkness springs up myriads of twinkling stationary lights and myriads of trains of moving lights of many different directions. It is as though activity from one of those local places which continued restless in the darkened main-mass suddenly spread far and wide and invaded all. The great topmost sheet of the mass, that where hardly a light had twinkled or moved, becomes now a sparkling field of rhythmic flashing points with trains of traveling sparks hurrying hither and thither. The brain is waking and with it the mind is returning. It is as if the Milky Way entered upon some cosmic dance. Swiftly the head mass becomes an enchanted loom where millions of flashing shuttles weave a dissolving pattern, always a meaningful pattern though never an abiding one; a shifting harmony of subpatterns. Now as the waking body rouses, subpatterns of this great harmony of activity stretch down into the unlit tracks of the stalk-piece of the scheme. Strings of flashing and travelling sparks engage the lengths of it. This means that the body is up and rises to meet its waking day.

It is difficult to get a hearing from busy men for even a great new truth.

The 'motion' of an energy-system is its 'behaviour'. Various types of organization of system produce on that basis various types of behaviour. A grey rock, said Ruskin, is a good sitter. That is one type of behaviour. A darting dragon-fly is another type of behaviour. We call the one alive, the other not. But both are fundamentally balances of give and take of motion with their surround. To make 'life' a distinction between them is at root to treat them both artificially.
