Last week I talked about the rock/plant/animal/human implicit categorization.

First of all, remember the rock/plant/animal/people distinction is just a made-up bucketing over a continuous phenomena.

But also, I think the model is missing an extra layer: 'god'.

A god is an entity that can think multiple plys beyond you; they will be powerful and inscrutable.

When you're playing against a god, the best you can do is hope they're not an evil god, and worship them so they are unlikely to want to squash you.
