Am I real? One would tend towards an answer of “Yeah, duh,” or perhaps an “Are you stupid?” Rolling one’s eyes would have the same effect as well, but hear me out! I am, admittedly, just a figment of my own perception. I can change my actions at will, and do so in a manner that depends on the person I am with. With Sally I act as is appropriate based on my past with Sally. This implies that the idea of “me” in the eyes of Sally as opposed to, say, “Pierre” would be different. Therefore, am I real?
