Evolution: Its nature, its evidence, and its relation to religious thought. Joseph LeConte

the same apprehended by the imagination and æsthetic sense, we call Beauty, and its embodiment Art, music. Now, in music there are two kinds of harmony, simultaneous and consecutive—chordal harmony and melody. These must be combined to produce the grandest effect. So in cosmic order, too, there are two kinds of harmonic relation—the co-existent in space and the consecutive in time. The law of gravitation expresses the universal harmonic inter-relation of objects co-existent in space, the law of evolution, the universal harmonic relation of forms successive in time. Of the divine spheral music, the one is the chordal harmony, the other the consecutive harmony or melody. Combined they form the divine chorus which “the morning stars sang together.”
