There is no such thing as a spiritual belief.
There is only spiritual experience.
To marvel at the Universe, feeling awe at its magnificence, admiring the beauty of the butterfly and the serenity of a snow-capped mountain, being lost in a symphony and beiing reverential to the complex biochemistry that sustains me: These are spiritual experiences that I have as a human being and as a scientist too.
They have nothing to do with any belief about or understanding of the world.
