The gap between 'the State' and 'a machine' is not so wide. - Charles Scott Sherrington

Natural science is a branch of knowledge by general consent not primarily based on the a priori. It […] observes and endeavours by observation to follow and trace the 'how' of what happens in Nature. It proceeds further to generalize about this 'how'. It tries to decipher something of it in the past and to forecast something of it in the future. Above all it expends its utmost pains on attempting to describe the 'how' fully and accurately by first-hand observation at this present.

Mind, for anything perception can compass, goes therefore in our spatial world more ghostly than a ghost. Invisible, intangible, it is a thing not even of outline; it is not a 'thing'. It remains without sensual confirmation, and remains without it for ever. All that counts in life. Desire, zest, truth, love, knowledge, 'values', and, seeking metaphor to eke out expression, hell's depth and heaven's utmost height. Naked mind.

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.
