”Man’s sight, smell, hearing, sense of locality— how inferior they are. The condor sees a corpse at five miles; man has no telescope that can do it. The bloodhound follows a scent that is two days old. The robin hears the earthworm burrowing his course under the ground. The cat, deported in a closed basket, finds its way home again through twenty miles of country which it has never seen.

Mark Twain, The Damned Human Race (via squirmedstoic)
