Of course dogs are different; this is not an exaggeration based on my experience. :-) Nor is it limited to doggies.

Though the philosopher in me must insist that Planck's constant only applies if we assume angels are material. Also, that the real question is whether a single angel can dance simultaneously on the points of multiple pins. In any event, I think humanities people exhibit a much better class of smugness. I like us.
