Probable Impossibilities: Musings on Beginnings and Endings

by Alan Lightman

Paradoxically, if we can give up the belief that our bodies and brains contain some transcendent, nonmaterial essence, if we can embrace the idea that we are completely material, then we arrive at a new kind of specialness—an alternative to the specialness of vitalism. We are special material. Not special because our atoms are different from atoms in rocks and water, and not special because we have a nonmaterial essence inside us, but special because our atoms are arranged in a special way as to create life, and consciousness. We humans living on our one planet wring our hands about the brevity of our lives and our mortal restraints, but we do not often think about how improbable it is to be alive at all. Of all the zillions of atoms and molecules in the universe, we have the privilege of being composed of those very, very few atoms that have joined together in the special arrangement to make living matter. We exist in that one-billionth of one-billionth. We are that one grain of sand in the desert.
