Here, we come upon what the dog knows: The scent of truth that eludes our inner handler and all his or her reasoning and overthinking. That truth is that there is both good and evil in the world, and thousands of years of human effort through religion, good works, social engineering, morality, ethics, and all the best of human love have failed to advance us in goodness or even in moral sophistication. There is nothing new under the sun.
The very, very best we can do is to reimagine the world as something it isn’t: to exchange the truth for a lie.
And that’s not doing anything at all, in reality. We never find out where the dead bodies really are.
