Extracts from the Wilhelm's I-Ching translation's introductory : ? The Book of Changes – I Ching in Chinese–is unquestionably one of the most important books in the world's literature. Its origin goes back to mythical antiquity, and it has occupied the attention of the most eminent scholars of China down to the present day [i. e. around 1920]. Nearly all that is greatest and most significant in the three thousand years of Chinese cultural history has either taken its inspiration from this book, or has exerted an influence on the interpretation of its text. Therefore it may safely be said that the seasoned wisdom of thousands of years has gone into the making of the I Ching. Small wonder then that both of the two branches of Chinese philosophy, Confucianism and Taoism, have their common roots here.
In the course of time, owing to the great repute for wisdom attaching to the Book of Changes, a large body of occult doctrines extraneous to it – some of them possibly not even Chinese in origin – have come to be connected with its teachings. The Ch'in and Han dynasties saw the beginning of a formalistic natural philosophy that sought to embrace the entire world of thought in a system of number symbols. Combining a rigorously consistent, dualistic yin-yang doctrine with the doctrine of the "five stages of change" taken from the Book of History, it forced Chinese philosophical thinking more and more into a rigid formalization. Thus increasingly hairsplitting cabalistic speculations came to envelop the Book of Changes in a cloud of mystery, and by forcing everything of the past and of the future into this system of numbers, created for the I Ching the reputation of being a book of unfathomable profundity.
These eight trigrams were conceived as images of all that happens in heaven and on earth. At the same time, they were held to he in a state of continual transition, one changing into another, just as transition from one phenomenon to another is continually taking place in the physical world. Here we have the fundamental concept of the Book of Changes. The eight trigrams are symbols standing for changing transitional states; they are images that are constantly undergoing change. Attention centers not on things in their state of being – as is chiefly the case in the Occident – but upon their movements in change. The eight trigrams therefore are not representations of things as such but of their tendencies in movement.
These eight images came to have manifold meanings. They represented certain processes in nature corresponding with their inherent character. Further, they represented a family consisting of father, mother, three sons, and three daughters, not in the mythological sense in which the Greek gods peopled Olympus, but in what might be called an abstract sense, that is, they represented not objective entities but functions.
