" Now, ignorant and backward persons will occasionally demand that you show them this configurational space of yours, apparently unaware that electrons, whose existence no one in his right mind would question, also move exclusively in configurational space, their comings and goings fully dependent on curves of probability. Though it is easier not to believe in electrons than in dragons: electrons, at least taken singly, won't try to make a meal of you. "
