There is no "I" in "You"

[quip]

Doesn't have to be.  What'd you come up with, when you were pondering it?

Well, the only rational thing I could come up with is that this sense...or temptation to ask myself, "why am I me and not anyone else" is just a physiological byproduct of existing as a conscious entity.  The very nature of consciousness lends its self to a feeling of separateness from the rest of what is going on "out there."  (Rob is gearing up to scratch his solipsistic itch [emoji6]).  The urge to ask, 'why aren't I experiencing reality from my husband's point of view, or someone else's?' is just a guilty philosophical indulgence.  I think the idea that there is a "reason" for it is just an illusion generated by our humanness.

Good response. Is the self itself such a generated illusion?  What exactly is the self..is it the body, mind or some odd commingling of both?

For me, it's very similar in nature to asking, "why is there something rather than nothing?"  Being human, I think we have all been tempted by this question at one time or another, but then we remind ourselves that rationality must always rule over the egocentric nature of human yearnings.

Problems persist when we conflate the two though.

Now, I must apologize because philosophy is NOT my bag, and I'm not sure any of what I just typed is coherent, lol.

Seems you're doing quite well....best answer thus far!
