The good parent: someone who doesn't mind, for a time, being hated by their children.
When I see someone like Richard Dawkins, I see my father. I grew up with that. I'm basically the child of Richard Dawkins.
The assumption is that life doesn't need to be navigated with lessons. You can just do it intuitively. After all, you only need to achieve autonomy from your parents, find a moderately satisfying job, form a relationship, perhaps raise some children, watch the onset of mortality in your parents' generation and eventually in your own, until one day a fatal illness starts gnawing at your innards and you calmly go to the grave, shut the coffin and are done with the self-evident business of life.
If the behaviour of babies and small children is any guide, we emerge into the world with our tendencies to imbalance already well entrenched. In our playpens and high chairs, we are rarely far from displaying either hysterical happiness or savage disappointment, love or rage, mania or exhaustion--and, despite the growth of a more temperate exterior in adulthood, we seldom succeed in laying claim to lasting equilibrium, traversing our lives like stubbornly listing ships on choppy seas.
