Wuxing (Chinese philosophy)

Wuxing (Chinese: 五行; pinyin: wǔxíng; Jyutping: Ng⁵ Hang⁴), translated as Five Moving Ones, Five Circulations, Five Types of Energy, Five Elements, Five Transformations, Five Phases or Five Agents, is a fivefold conceptual scheme used in many traditional Chinese fields of study to explain a wide array of phenomena, including terrestrial and celestial relationships, influences, and cycles, that characterise the interactions and relationships within science, medicine, politics, religion and social relationships and education within Chinese culture.

The Five Moving Ones are traditionally associated with the classical planets: Mars, Mercury, Jupiter, Venus, and Saturn as depicted in the etymological section below. In ancient Chinese astronomy and astrology, that spread throughout East Asia, was a reflection of the seven-day planetary order of Fire, Water, Wood, Metal, Earth. When in their "heavenly stems" generative cycle as represented in the below cycles section and depicted in the diagram above running consecutively clockwise (Wood, Fire, Earth, Metal, Water). When in their overacting destructive arrangement of Wood, Earth, Water, Fire, Metal, natural disasters, calamity, illnesses and disease will ensue.

The wuxing system has been in use since the second or first century BCE during the Han dynasty. It appears in many seemingly disparate fields of early Chinese thought, including music, feng shui, alchemy, astrology, martial arts, military strategy, I Ching divination, religion and traditional medicine, serving as a metaphysics based on cosmic analogy.

Wuxing originally referred to the five classical planets (from brightest to dimmest: Venus, Jupiter, Mercury, Mars, Saturn), which were with the combination of the Sun and the Moon, conceived as creating the five forces of earthly life (including yang and yin). This is why the word is composed of Chinese characters meaning "five" (五; wǔ) and "moving" (行; xíng). "Moving" is shorthand for "planets", since the word for planets in Chinese has been translated as "moving stars" (行星; xíngxīng). Some of the Mawangdui Silk Texts (before 168 BC) also connect the wuxing to the wude (五德; wǔdé), the Five Virtues and Five Emotions . Scholars believe that various predecessors to the concept of wuxing were merged into one system of many interpretations in the Han dynasty.

Wuxing was first translated into English as "the Five Elements", drawing parallels with the Greek and Indian Vedic static, solid or formative arrangement of the four elements. This translation is still in common use among practitioners of Traditional Chinese medicine, such as in the name of Five Element acupuncture and Japanese meridian therapy. However, this analogy could be misleading as the four elements are concerned with form, substance and quantity, whereas the post-heaven arrangement of the wuxing are "primarily concerned with process, change, and quality". For example, the wuxing element "Wood" is more accurately thought of as the "vital essence" and growth of trees rather than the physical innate substance wood. This led sinologist Nathan Sivin to propose the alternative translation "five phases" in 1987. But "phase" also fails to capture the full meaning of wuxing. In some contexts, the wuxing are indeed associated with physical substances. Historian of Chinese medicine Manfred Porkert proposed the (somewhat unwieldy) term "Evolutive Phase". Perhaps the most widely accepted translation among modern scholars is the "five agents" or "five transformations".

In traditional doctrine, the five phases are connected in two cycles of interactions: a promoting or generative (生 shēng) cycle, also known as "mother-son"; and an overacting or destructive (克 kè) cycle, also known as "grandfather-grandson" (see diagram). Each of these cycles can be interpreted and analyzed in a forward or reversed direction. In addition to the aforementioned cycles there is also what is considered an "overacting" or excessively generating version of the destructive cycle.^{[citation needed]}
