Sample text

The division between matter and mind is absolute. In one crucial respect, Aristotle stood the system of his mentor, Plato, on its head. For him, change is not necessarily a falling away from intelligibility: it is the very means through which the intelligibility of the world around us is to be discerned. The paradigm for him was the living world, not the world of mathematical Form. He looked to behaviour – that is, change – to understand what a nature is, to what kind it belongs. Mathematical forms may be imperfectly realized by wooden triangles or copper squares, but living forms, in contrast, are ordinarily fully realized in the individual member of the species.

In any event, it appears rather strained to qualify it as ‘matter’. If that protean term is to be used at all in the cosmic context, it is best to say that the universe consists of matter and energy. And if one has to have a generic term to apply to the universe as a whole, then ‘energy’, rather than ‘mass–energy’, would seem (for the moment, at least) to be the proper one. The density term at the cosmic level would then simply be ‘energy density’. 3 Three What, then, of ‘materialism’? Ought that label to be replaced with ‘energeticism’?

In the Einstein field equations, the stress-energy tensor on the right-hand side describes the sources of the gravitational field, and these now include energy, both kinetic and potential, as well as rest mass. These can be summed together with the aid of the equivalence. So a photon, for example, despite having zero rest mass, will exert gravitational force in virtue of its kinetic energy. And a tightly wound watch will contribute slightly more to gravity in virtue of its potential energy than one that has run down.
