Indeed, without resorting to metaphysics, I don't know whether any other beings besides myself are self-aware or just pretending. I have good reasons to believe other humans are self-aware, but I can't prove it scientifically. It's too bad that scientists tend to be so dismissive of philosophy; I think some rigorous metaphysics would really help in this field.
