Who defines what an animal is? Is an animal rational or irrational? Are the animals inside of us or outside? Descartes wondered how they were different from machines.
In what way are we different from animals? We are reproducing and consuming our way into overshoot, just like any animal. Do they know about overshoot as well but, like us, cannot help themselves?
I look outside and I see the landscape reasoning with itself. How to handle water, how to manage grass.
Reason (if it ever existed at all) is possibly the most delicate thing in the world – a dream before dawn, a fleeting glimpse. Something we thought we saw, for a moment, like God.
Reason, which the Founding Fathers invoked, is rooted in that strange medieval hierarchy, with God (pure Reason) at the top, certain kinds of men in the middle, and animals below. Animals therefore have no Reason because they are the opposite of God. Or something like that.
(Not everyone threw the animals out, for instance, Montaigne.)
The reason we build, we build together – men with women, tribe with tribe, human with animal. Pure Reason is delicate and distant, like God. Every other kind of reason we will have to keep working on.
