儒家宇宙起源学:易有太极,是生两仪 The Confucian Cosmogony: Supreme Ultimate Produces Two Forms

宇宙起源学是指有关宇宙如何形成或来源,或现实的形成的学说。当代的看法趋向于认为宇宙有个开始,而这个开始是宇宙演化的一个阶段。在中国,两千年前道家与儒家对宇宙的看法都与当代的观点相似。
可是,从古典经书中,我们却没法看到孔子对这个课题的明确观点。孔子死后,不少儒学者从《易经》的学习而发展出一套儒家的宇宙起源学说。《易经》一直被认为是儒家经典之一。周敦颐(1017-1073)就是其中的一个儒家学者。
《易经》里说,‘易有太极,是生二仪。’周敦颐由此而画出《太极图》并阐述他的宇宙起源《太极图说》:

无极而太极。太极动而生阳,动极而静,静而生阴,静极复动。一动一静,互为其根;分阴分阳,两仪立焉。
阳变阴合,而生水、火、木、金、土,五行顺布,四时行焉。
五行一阴阳也,阴阳一太极也,太极本无极也。五行之生也,各一其性。
无极之真,二五之精,妙合而凝。乾道成男,坤道成女。二气交感,化生万物,万物生生而变化无穷焉。’
.
Cosmogony refers to theory concerning the coming into existence or origin of the universe, or about how reality came to be. Contemporary opinion tends to consider that the universe had a beginning, and that this beginning was a stage in the evolution of the universe. Both Daoism and Confucianism in China seem to propose a similar view of the universe for the past two thousand years.
However, the Confucius position on this matter has never been not clearly articulated in any of the classical texts. It was only after the dearth of Confucius that a number of Confucian scholars studied and developed their cosmogonies based on the Book of Changes (Yijing), which is considered to be one of the classical texts of Confucianism. One of them was Zhou Dunyi (1017 – 1073).
In Yijing, it says, ‘In the Yi there is the Supreme Ultimate, which produces the Two Forms.’ Based on this, Zhou came out with a diagram called ‘Taiji Tu’, or the Diagram of the Supreme Ultimate and then he developed the Confucian theory of cosmogony (Taiji Tushuo):

‘The Ultimateless! And yet the Supreme Ultimate! The Supreme Ultimate through Movement produces the Yang. This Movement, having reached its limit, is followed by Quiescence, and by this Quiescence, it produces the Yin. When Quiescence has reached its limit, there is a return to Movement. Thus Movement and Quiescence, in alteration, become each the source of the other. The distinction between the Yin and Yang is determined and the Two Forms (ie Yin and Yang) stand revealed.
By the transformations of the Yang and the union therewith of the Yin, Water, Fire, Wood and Metal and Earth are produced. These Five Elements (wuxing) become diffused in harmonious order, and the four sessions produced in their course.
The Five Elements and the one Yin and Yang, the Yin and Yang are the one Supreme Ultimate, and the Supreme Ultimate is fundamentally the Ultuimateless. The Five Elements came into being each having its own particular nature.
The true substance of the Ultimateless and the essence of the Two (Forms) and Five (Elements), unite in mysterious union, so that that consolidation ensures. The principle of Qian (the trigram symbolising Yang) becomes the male element, and the principle of Kun (the trigram symbolising Yin) becomes female elements. The Two Forms (ethers, the Yin and Yang) by their interaction operate to produce all things, and these in their turn produce and reproduce, so that transformation and change continue without end.’
