the dualistic relationship between the sith' and the jedi' concepts of "purity" mirrors the philosophical and literary concept of "apollonian and dionysian": the jedi are portrayed as embracing purity, reason, temperance, altruism and other humanistic virtues; the sith, by contrast, embrace curiosity, emotion, conflict, power, instincts, unfettered self-interest and other hedonistic vices. however, whereas the classic greek concept did not necessarily view the apollonian and dyonisian principles as opposed, "star wars" frames the jedi and sith as opponents in a dire moral struggle, with the sith cast as corrupted villains apparently destined to defeat or self-destruction in the end. although a path to temporary power, the sith way inevitably leads to ruin.
