Although I disagree with Percy about there being a higher purpose, I will note that he didn’t say we had individual higher purposes. It could be that we: the human race, or we: all life on Earth, have a common purpose. Even if we have individual purposes, he didn’t say that we all eventually fulfill them, or that all our actions move us closer to the end goal.
Maybe only a subset of us have a Purpose, while the rest of use serve as context. Not a comforting thought, but why not?
