Civilization is a progress from an indefinite, incoherent homogeneity toward a definite, coherent heterogeneity.

This survival of the fittest, which I have here sought to express in mechanical terms, is that which Mr. Darwin has called "natural selection, or the preservation of favoured races in the struggle for life."

Evolution is an integration of matter and concomitant dissipation of motion during which the matter passes from an indefinite incoherent homogeneity to a definite coherent heterogeneity, and during which the retained motion undergoes a parallel transformation.

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.

A fire-mist and a planet, A crystal and a cell, A jellyfish and a saurian, And caves where the cavemen dwell; Then a sense of law and beauty, And a face turned from the clod-- Some call it Evolution, And others call it God.

Music must take rank as the highest of the fine arts - as the one which, more than any other, ministers to the human spirit.
