At a certain occasion when somebody asked him if he believed in God, Einstein would have answered "yes, the God in which I believe is the God of Spinoza ". As a matter of fact, Einstein noticed as nobody before that the "God, in other words, the Nature" of Spinoza was reflected from the tiniest electronic spin to the most extensive galaxies of the universe. For Einstein, the science could not just be an useful calculation for the technological applications, but it would have an almost religious dimension. For both, God is the intelligent and self-conscious Nature always much wider than any thing just described by numbers or words. God is the Garden that does not need a gardener, because it is made by Himself. The human being is so-only a teeny thinking bush of limited existence planted in this limitless Garden which shimmers with mystery and fright.
