Civilization is never going to collapse. This is the beauty of the dialectic. Like a pot of boiling water, it is always heating up, but has a distinct point where it is no longer liquid. Civilization will always move forward, but it will have times where we can say it is qualitatively different from this other time, but like the steam and the water, it is still the same in substance. We become anxious because we see one particular enthralling spectacle of society and it consumes us. It becomes our passion and the subject of all our desires and worries. Breaking away from it is challenging, but in doing so you are able to see the whole of the world more freely and accept your role in history not as some great man who must bear the weight of the world on his shoulders, but as an individual molecule, sharing heat with all the other molecules until you just happen to float away into the sky.
