 To be an individual power, Clarke tells us, a power must be truly unitary, and thus not composed of parts. Call this the Individual Power Principle. So, consciousness is an individual power, which belongs to an individual being, the soul. The soul, too, is so unified that it does not have parts. Magnitude, in contrast, satisfies the Composition Principle but is not an individual power. This is because the matter to which it belongs can always be divided, or more precisely, actually is divided.
