When DC Comics reissued Alan Moore's Saga of the Swamp Thing in 2009, reviewers hailed the series as "an undeniable classic of modern comics." Swamp Thing introduced Moore to US readers two years before his most highly regarded and influential work, Watchmen, which critics have argued precipitated the comic book industry's creative shift from the so-called Bronze Age to what readers variously term the Dark or Modern Age. Given the parallels in their works, Moore's readership may have included Donald Davidson, one of the most influential philosophers of the last fifty years. Though it is impossible to determine influence, Davidson's thought experiment appears at least as pop-cultural as philosophical.
