In 1932 Albert Einstein wrote and recorded a few short paragraphs that he called ‘My Credo’ that summarize quite beautifully and succinctly his thoughts on “the contemplation and exploration of objective and timeless things”, his “passion for social justice”, and the role of mystery in the pursuit of art and science.
The most beautiful and deepest experience a man can have is the sense of the mysterious. It is the underlying principle of religion as well as of all serious endeavour in art and science. He who never had this experience seems to me, if not dead, then at least blind. To sense that behind anything that can be experienced there is a something that our minds cannot grasp, whose beauty and sublimity reaches us only indirectly: this is religiousness. In this sense I am religious. To me it suffices to wonder at these secrets and to attempt humbly to grasp with my mind a mere image of the lofty structure of all there is.
