In the (3) I gave, you're indexed so that the thermal fluctuation doesn't dissolve until November 1, so your actions still have consequences. > I will throw a fair coin.

This is one of a larger class of problems related to volition, and the coupling of my qualia to an external reality, that I don't currently have an answer for. I want to live on in the current Universe, I don't to die and have a duplicate of myself created in a different Universe. I want to eat a real ice cream cone, I don't want you to stimulate my neurons to make me imagine I'm eating an ice cream cone. I would argue that a world where I can interact with real people is, in some sense, better than a world where I interact with imaginary people who I believe are real. > Well, let's consider an agent who happens to have preferences of a special > form.

You have a general model, which can encompass classical decision theory, but can also encompass other models as well. It's not immediately clear to me what benefit, if any, we get from such a general model. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
