Vertiginous question
The vertiginous question, as presented by Benj Hellie, asks why, of all the subjects of experience, it is this one—the one corresponding to the person named Benj Hellie—whose experiences are lived (one is supposed to insert one's own case for Hellie's). In other words: Why am I me and not someone else?
A simple response is that this question reduces to "Why are Hellie's experiences lived from Hellie's perspective", which is trivial to answer. But Hellie argues, through a parable, that this response leaves something out. His parable describes two situations, one reflecting a broad global constellation view of the world and everyone's phenomenal features, and one describing an embedded view from the perspective of a single subject. The former seems to align better with the simple response above, but the latter seems to be a better description of consciousness.
