Division into two principles or kinds Dualism is a family of views that propose a fundamental division into two separate principles or kinds. It typically emphasizes a sharp distinction between independent or antagonistic sides, but in a broader sense, it also includes theories in which the two sides are correlated or complementary. Dualism contrasts with monism, which rejects any fundamental division, and with forms of pluralism that posit more than two basic principles. 572,924 views on April 15, 2016 — Wikipedia's most-read article that day.
