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 richer we have become materially, the poorer we have become morally and spiritually.

Unless you have found God in your own soul, the whole world will seem meaningless to you.

I don't think I've ever been an agnostic. I've always thought there's a superior power, that this is not the real world and that there's a world to come.

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.

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.
