Some of these big words are just concepts that doesn’t really mean anything without a clearly defined context.
Back when Humanists like Camus where active the context was like:
“Ok, god probably doesn’t exist, so now we have to find new answers to all of these questions”
But today we know even more and should start asking if the concept of “meaning” is even applicable to a single human life but rather humanity as a group (or a processes).
