So it seems to me that Absurdism is very much coming out a feeling of an absence of meaning.
I recall that Joshua said both on a podcast and somewhere on the forum, that trying to find meaning was actually a very recent occurrence...was it not until sometime in the 1800's ? (I need to find that thread, or Joshua can you remind me what you said about the history of the question of the meaning of life?)
And I wonder if it comes from western civilization's paradigm of passing through Christianity. Christianity has us live this life only as a kind of preparation for an eternity in heaven. But when you question and reject the existence of God and heaven, you can be left with a kind of "now what?" It's like telling someone "Don't think of elephants" and all you can do is think of elephants. So then we need a new paradigm, and perhaps a modern Epicureanism is exactly what is needed.
