Tao Te Ching

“Almost the only important work of metaphysics in its literature is the strange document with which the recorded history of Chinese thought begins—the I Ching, or 'Book of Changes.' All science and history were contained in the changeful interplay of the combinations; all wisdom lay hidden in the 64 hsiangs... all reality could be reduced to the opposition and union of these two basic factors—the male and female principles, the yang and the yin.”
