We owe a huge debt to Galileo for emancipating us all from the stupid belief in an Earth-centered or man-centered (let alone God-centered) system. He quite literally taught us our place and allowed us to go on to make extraordinary advances in knowledge.
You all know the argument from design: everything in the world is made just so that we can manage to live in the world, and if the world was ever so little different, we could not manage to live in it. That is the argument from design. It sometimes takes a rather curious form; for instance, it is argued that rabbits have white tails in order to be easy to shoot. I do not know how rabbits would view that application.
You cannot be truly humble, unless you truly believe that life can and will go on without you.
In the twentieth century nothing can better cure the anthropocentrism that is the author of all our ills than to cast ourselves into the physics of the infinitely large (or the infinitely small). By reading any text of popular science we quickly regain the sense of the absurd, but this time it is a sentiment that can be held in our hands, born of tangible, demonstrable, almost consoling things. We no longer believe because it is absurd: it is absurd because we must believe.
Humans are the most important entity in the universe … only to most people.
