No Celine would have seen gusto in everything, meaning if you are going to engage in any of these activities do so with full fervor. He did view life as absurd because he saw it in the actions of others which he takes much time to describe. And no he was not a nihilist, he was quite political if you will and was jailed in France for treason, he was an anti-semite and sympathized with the nazi's though to what degree is debatable as far as their ultra nationalism which I believe he would have found 'absurd'. Celine would not have found life without value or meaning afterall he was a physician and worked hard in the poorest of areas offering his services. Tis funny. He would have found this discussion absurd really. He would have asked what could be more absurd than to try and box or label the entire canon of literature. And even more worth hilarity would be to have a discussion when one of them hasn't read his work which I am sure would have bruised his French ego. He would have also found a discussion of this sort in a medium like this crazy as 'all life is awaiting us'. But on we go. Moving away from any particular work for a moment I would like to ask you what significance do you think your assertion has? Meaning what would it mean to you if this turned out not to be true in every single work of literature? What does it mean to you if it turned out to be true? Or a better question even is what do you think is the purpose of literature? I think it would broaden the discussion a little and perhaps further emphasize all that you think is 'spirituality' a definition we haven't yet come to any consensus on in terms of literature in general.
