“For it is feeling and force of imagination that makes us eloquent.”

"G. B. S. — Mark V", in I Sing the Body Electric: And Other Stories (1998)
Context: We are the miracle of force and matter making itself over into imagination and will. Incredible. The Life Force experimenting with forms. You for one. Me for another. The Universe has shouted itself alive. We are one of the shouts.

Second Sestiad
Hero and Leander (published 1598)

1 September 1875, page 226
John of the Mountains, 1938
Context: How infinitely superior to our physical senses are those of the mind! The spiritual eye sees not only rivers of water but of air. It sees the crystals of the rock in rapid sympathetic motion, giving enthusiastic obedience to the sun's rays, then sinking back to rest in the night. The whole world is in motion to the center. So also sounds. We hear only woodpeckers and squirrels and the rush of turbulent streams. But imagination gives us the sweet music of tiniest insect wings, enables us to hear, all round the world, the vibration of every needle, the waving of every bole and branch, the sound of stars in circulation like particles in the blood. The Sierra canyons are full of avalanche debris — we hear them boom again, for we read past sounds from present conditions. Again we hear the earthquake rock-falls. Imagination is usually regarded as a synonym for the unreal. Yet is true imagination healthful and real, no more likely to mislead than the coarser senses. Indeed, the power of imagination makes us infinite.

Unsourced variant : Government is not reason, it is not eloquence, it is force; like fire, a troublesome servant and a fearful master. Never for a moment should it be left to irresponsible action.

Music For All Of Us (1943); also quoted as "...Music can be all things to all persons... "
Context: I believe that music can be an inspirational force in all our lives — that its eloquence and the depth of its meaning are all-important, and that all personal considerations concerning musicians and the public are relatively unimportant — that music come from the heart and returns to the heart — that music is spontaneous, impulsive expression — that its range is without limit — that music is forever growing — that music can be one element to help us build a new conception of life in which the madness and cruelty of wars will be replaced by a simple understanding of the brotherhood of man.
Music can be all things to all men. It is like a great dynamic sun in the center of a solar system which sends out its rays and inspiration in every direction. … It is as if the heavens open and a divine voice calls. Something in our souls responds and understands. We are speaking here of the most inspired music.
