The real problem is that through our scientific genius we've made of the world a neighborhood, but through our moral and spiritual genius we've failed to make of it a brotherhood.

The trouble isn't so much that our scientific genius lags behind, but our moral genius lags behind. The great problem facing modern man is that, that the means by which we live have outdistanced the spiritual ends for which we live.

Whenever racial discrimination exists it is a tragic expression of man's spiritual degeneracy and moral bankruptcy. Therefore, it must be removed not merely because it is diplomatically expedient, but because it is morally compelling.

The moral philosophy and spiritual conceptions of men and nations should hold their own amid these formidable scientific evolutions...No material progress, even though it takes shapes we cannot now conceive, or however it may expand the faculties of man, can bring comfort to his soul.

We cannot long survive spiritually separated in a world that is geographically together.

If our history can challenge the next wave of musicians to keep moving and changing, to keep spiritually hungry and horny, that's what it's all about.
