People must have renounced, it seems to me, all natural intelligence to dare to advance that animals are but animated machines.... It appears to me, besides, that such people can never have observed with attention the character of animals, not to have distinguished among them the different voices of need, of suffering, of joy, of pain, of love, of anger, and of all their affections. It would be very strange that they should express so well what they could not feel.
I got into an argument with a girlfriend inside of a tent. That's a bad place for an argument, because then I tried to walk out and slammed the flap. How are you supposed to express your anger in this situation? Zipper it up really quick?
