More on the relating self...
More generally, I think that the term "self" when we apply it to other people is a completely different concept from the term "self" we must use to define ourselves. My definition of myself is not something separate from me but a constantly updated set of conscious and tacit knowledge and “memories” that exist inseparably from my body/mind. How I define other people and conceptualize their "selves" is secondary however, because I can never know/experience how they actually relate to the world, but rather can only understand how they relate to the world through the lens of my own relationship to the world. Trying to conceive of ourselves in the same way we conceive of others - similarly to what I was saying above - could also provide conflict, because conclusively it is an impossible goal!
