The guy who wrote this is an expert in evolution (as in neodarwinism). When he says We are the pilots of ultra-violent ancestry, he probably refers to our ancestors' behaviour, which is part of us, part of our genes. We are not alone, inside each living being there's a ton of ancestors, a genetic heritage, things such as practical instincts like being afraid of lightning and/or a basic set of instructions for everyday life (look for food when you're hungry, sleep when you're tired, etc.). And of course our ancestors are also in our culture, which is also inside of us, the things you learned (and cared about) in school, the books you read with attention (it's like the author is in some part of your mind), the deep values your parents (hopefully) gave you.

I guess the message is we can be ourselves, despite such influences, such intruders (ghosts), by zest (courage, will) and artistry (skill). We can overcome what's bad, we don't have to act like animals, or like our ancestors, we can be better than that. We don't need exorcism to get rid of this bad influence, we just need a key to our own freedom.
