Reasons aren't really things that make you do other things. Reasons are things that you make up, much later, to reassure everyone that we are all logical and that the world makes sense. We do unreasonable things, because we want to, at the time. No reason. Much later we sit in the wreckage, building reasons out of little bits of wreckage, so we'll have something to show the crash investigators. Look, this is what caused it. So the whole mess at least appears reasonable. So we can convince ourselves that at least there was a reason for the disaster, something we can prevent or avoid, so it'll never happen again. But a lot of the time there's no reason. We just flew it to the ground. Because we felt like it. And we're still dangerous. And it could happen again anytime. Its easier to live with each other afterwards if we give each other reasons.
