1. I read this a long time ago and was not impressed, but that was so long ago I may well have failed to appreciate its significance. Seems like this has come up a number of times and we need to find a good source for the text and start a new thread on it. If I recall correctly I saw it originally on a Marxism page, but that page seems to be gone.
PPS Also, I recently read that Karl Marx's doctoral dissertation some time in the 1840s was a comparison of Democritus' and Epicurus' atomism, finding Epicurus' teaching was consistent with the Young Hegalians philosophical views which he favored.

Can I conclude that Prof Nail's essay under consideration here is not relevant to whether Lucretius ignored Epicurus' atomism? I think the answer is that it is not.
I may be losing the thread of the discussion in my mind but if what you mean is that the Nail essay does not provide a good argument that Lucretius was deviating from Epicurus, I think you're correct that in my mind it doesn't.
