Abstract

In the universe, there are countless pairs of opposites. In Chinese philosophy, there are general names for these opposites, i.e., yin and yang. In this paper I argue that the unity of opposites is a theme common to Heraclitus, a pre-Socratic philosopher, and Laozi, the best known Daoist. More specifically, I argue that both Heraclitus and Laozi believe the following: 1) opposites produce and depend on each other, without one there can’t be another; 2) each thing in the universe consists of opposites and is a unity of opposites, there is nothing that is absolutely one-sided; 3) the conflict between opposites changes everything and makes new things possible. Nothing is at rest and new beings constantly come to exist, since there is constant struggle between opposites. As far as their views on the unity of opposites are concerned, Heraclitus’s and Laozi’s philosophies are extremely similar.
