The problem of human evil has always occupied the mind of mankind. Even religious leaders have opined that it is inherent in human nature. Hindu cosmology states that it is cyclic & righteousness declines with the Yugas.
But the American writer Richard Bach wondered what if a culture grew up without evil? What would it do with all the energy that is now spent on destructive activities? A world where we choose our highest right & not our darkest wrong & where we lift each other up instead of always putting each other down? The result was a book called "Curious Lives" where these ideas are worked out by a society of ferrets.

Sadly this was the only work of Gaskell in these lines, her other novels dealing with ordinary humans in all their exasperating diversity.
