Interesting to consider:
(1) Is Lucretius appealing figuratively, or literally, to the goddess of pleasure to bring peace to his world?
(2) Is Lucretius also saying that it is true and appropriate BOTH that (a) his own mind cannot work on the poem unburdened by distress, AND (b) that Memmius cannot fail but to participate in the actions of his time?
