For evil in the open is but evil from within that has been let out. - Yann Martel

"I would have liked to say, "I'm a doctor," to those who asked me what I did, doctors being the current purveyors of magic and miracle. But I'm sure we would have had a bus accident around the next bend, and with all eyes fixed on me I would have to explain, amidst the crying and moaning of victims...I would have to confess that as a matter of fact it was a bachelor's in philosophy; next, to the shouts of what meaning such a bloody tragedy could have, I would have to admit that I had hardly touched kierkegaard; and so on."

I don't mean to defend zoos. Close them all down if you want (and let us hope that what wildlife remains can survive in what is left of the natural world). I know zoos are no longer in people's good graces. Religion faces the same problem. Certain illusion about freedom plague them both.

When your own life is threatened, your sense of empathy is blunted by a terrible, selfish hunger for survival.
