The very fact that we care about nature at all or are overwhelmed by its beauty, by the secrets of its operation, and by its unthinkable size is evidence of this truth. My dogs would not care in the slightest about a trip to the Grand Canyon and my appreciation of the wonder of that place is not simply the result of higher intelligence. If I am nothing more than a highly intelligent animal, than the Grand Canyon is nothing more than a hole in the ground.
