I continue to believe contrary to the given wisdom that it's more interesting to have an album - or indeed an individual song - which has variety rather than homogeneity.

When I speak of 'cycles ' I am referring to lengthy intervals of relative homogeneity if not in the resolving of problems than at least with respect to the consistency of their capacity to productively irritate.

The more specific idea of Evolution now reached is - a change from an indefinite incoherent homogeneity to a definite coherent heterogeneity accompanying the dissipation of motion and integration of matter.
