The human soul yearns for discovery. By unlocking the mysteries of the universe, we unlock truths within ourselves. That's true. Our journey into space will not only make us stronger and more prosperous, but will unite us behind grand ambitions and bring us all closer together. Wouldn't that be nice? Can you believe that space is going to do that? I thought politics would do that. (Laughter.) Well, we'll have to rely on space instead.

I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.

Almost the chief mystery of life is what makes one do things.

That's the problem with a lot of things these days. Everything is too full now; we are spoon-fed everything. All songs are about one thing and one thing specifically, there is no shading, no nuance, no mystery. Perhaps this is why music is not a place where people put their dreams at the moment; dreams suffocate in these airless environs.

Love is an endless mystery, for it has nothing else to explain it.

Love's over brimming mystery joins death and life. It has filled my cup of pain with joy.
