One thing that gets talked about often when people talk about philosophy (perhaps a stereotype of what philosophers do) is the question of the meaning of life, "what is the meaning of life?"
One concern I have with this question is that it's not entirely clear to me what the question means or whether it makes sense, since meaning comes after life. You first have life, and then develop a conception of "meaning". So perhaps it doesn't make sense to ask for what life means because the idea of "meaning" is something we have just created while living.
I don't really know if my point is clear, but I was wondering if any philosophers have written about something like this, perhaps challenging the premise of the question of the meaning of life. I'm very interested to read about how philosophers either defend the validity of this question or criticize it.
