Dualistic cosmology
Moral dualism is the belief of the great complement of, or conflict between, the benevolent and the malevolent. It simply implies that there are two moral opposites at work, independent of any interpretation of what might be "moral" and independent of how these may be represented. Moral opposites might, for example, exist in a worldview which has one god, more than one god, or none. By contrast, duotheism, bitheism or ditheism implies (at least) two gods. While bitheism implies harmony, ditheism implies rivalry and opposition, such as between good and evil, or light and dark, or summer and winter. For example, a ditheistic system could be one in which one god is a creator, and the other a destroyer. In theology, dualism can also refer to the relationship between the deity and creation or the deity and the universe (see theistic dualism). This form of dualism is a belief shared in certain traditions of Christianity and Hinduism. Alternatively, in ontological dualism, the world is divided into two overarching categories. The opposition and combination of the universe's two basic principles of yin and yang is a large part of Chinese philosophy, and is an important feature of Taoism. It is also discussed in Confucianism.
Hundred Schools of Thought
Philosophical Taoism or Daoism (道家; "Dàojiā"; "Tao-chia"; "School of the Way") developed into the second most significant stream of Chinese thought. Its formulation is often attributed to the legendary sage Laozi ("Old Master"), who is said to predate Confucius, and Zhuangzi (369–286 BC). The focus of Taoism is on the individual within the natural realm rather than the individual within society; accordingly, the goal of life for each individual is seeking to adjust oneself and adapting to the rhythm of the natural (and the supernatural) world, to follow the Way (tao) of the universe, and to live in harmony. In many ways the opposite of rigid Confucian morality, Taoism was for many of its adherents a complement to their ordered daily lives. A scholar serving as an official would usually follow Confucian teachings, but at leisure or in retirement might seek harmony with nature as a Taoist recluse. Politically, Taoism advocates for rule through inaction, and avoiding excessive interference.
