What’s the probability that there really isn’t a chair under my butt right now and that all my sense are fooling me? meh, I don’t know, low enough that I expect the time it takes me to think through an actual probability to have negative expected utility for my life, hence, epsilon = low enough that it’s not worth thinking about. Good bayesians don’t assign explicit mental probabilities to every proposition encountered in daily life, they balance the expected reward of doing the calculation against the cost of doing so.
