Yesterday's senseless killing has been overtaken by a far more significant one.
Many years ago I read a prizewinning novel, and amongst the opening rambles before the story really got going was a general discussion about the ethics of keeping large animals in zoos. As the child of a zookeeper the narrator was obviously on the positive side, and the main point of that little justification is worth trying to remember...
If the gates of an enclosure are left open, the animal may go for a quick wander outside, but will invariably wander back. Why? Because the enclosure is its territory. It has well defended boundaries, plentiful food, shelter and protection. Unless searching for a mate, most animals could not ask for more.
Those are my recollections, but that was recalling a work of fiction that I last looked at many years ago. The narrator Pi might have been deluded anyway, he claimed to have been stuck on a small boat with a fully grown tiger. Was there any evidence for his story? And if there is none, what can we learn from his delusion? Could a delusion justify the killing?
