Experience as coherent engagement in a world proves nothing about the reality of that world outside of awareness since the evidence it would supply can only occur within awareness. This is like the argument from dreams in which the dreamers world makes perfect sense but only for the dreamer. In thought, action, intention, perception there is nothing that reaches out beyond the experiencing in spite of the fact that all of these phenomena seem to refer beyond themselves. There is an intention and the corresponding act follows, but you can't actually link the intention to the action, each is an arisal complete in itself. All of these phases, including the simple faith in learned and effectively unconscious actions, have no being apart from the awareness, apart from the simple coherent world that appears, moment by moment.
