I can only look from the outside (or cut into the inside, but flesh and genes do not reveal organic totality). I am stuck with a panoply of ineluctably indirect methods - some very sophisticated to be sure. I can atomize, experiment, and infer. I can record reams of data about behaviors and responses. But if I could be a beetle or a bacillus for that one precious minute - and live to tell the tale in perfect memory - then I might truly fulfill Darwin's dictum penned into an early notebook containing the first full flowering of his evolutionary ideas during the late 1830's: "He who understands the baboon would do more towards metaphysics than Locke."
