The author of the text (found via google books) seems to be summarizing Epicurus in contrast to Democritus, rather than directly quoting. Certainly the block formatting makes it look like a quotation, but I don't think that's the case. He's correct that Epicurus disagrees with Democritus on the subject of Determinism.
