Eric Barnes - while appreciating the benefits of taking one box - has harsh words for the "taking one box is rational" folk.

I go on to claim that although the ideal strategy is to adopt a necessitating disposition to take only one box, it is never rational to choose only one box. I defend my answer against the alternative analysis of the paradox provided by David Gauthier, and I conclude that his understanding of the orthodox theory of rationality is mistaken.
