This quote is new to me, but it appears well sourced. I say that because: (1) It is certainly a reasonable thing for an admirer of Lucretius, like Frederick the Great is known to have been, to say. I too am an admirer of Lucretius, and I think the same thing most every day! Further, (2) it comes quoted from what I understand to be a reputable text (Niall Ferguson's "Civilization, the West and the Rest"). If anyone has evidence that indicates that this quote is spurious, please post and I'll retract point (2).
Further, if anyone knows the exact source, please post that too. Obviously this is a translation so it would be good to know the name of the translator too. Presumably from wherever this comes, there is more of interest.
