In the 1930s, the government paid writers to interview 80- and 90-year-old former slaves, and I read those accounts. I came away realizing - not surprisingly - that many slave masters were sadists who spent a lot of time thinking up creative ways of hurting people.
When it comes to how the slaves treat each other: If you've been brutalized all your life - if you have seen your children sold or your mother beaten and raped and you have been tortured yourself - you are not going to be up for your best behaviour. Even in the 21st century, 100 people in the midst of terrible suffering are not going to be their best people.
In keeping with my family's affection for doomed product lines and hexed formats, we purchased a Betamax. The year before, we'd bought a TRS-80 instead of an Apple II, and in due course we'd unbox Mattel's Intellivision, instead of Atari's legendary gizmo. This was good training for a writer, for the sooner you accept the fact that you are a deluded idiot who is always out of step with reality the better off you will be.
I'm not really up on what's new. I'm still listening to Run DMC twenty-five years later. In the same way that the baby-boomers in America were forcing '60s music and Motown down our throats, now people of my generation are forcing Tears For Fears and old Hip Hop upon others.
I can't say that you should extract this or that value from my books explicitly. They are up for interpretation. In terms of the obligation, I think we're all individuals on this planet, trying to scratch our way through the day, and if you're writing a book exposing atrocities in Rwanda or writing a murder mystery set in a mountain village, I think both ways of spending you time are valid and both books are probably fine to read.
