In the history of Western thought, the philosophical study of man has been part of the philosopher's pursuits from the time of the ancient Greeks. But after a lapse of over two thousand years, the study in this field remains not much developed and its achievements are far from satisfactory. Already in 1928, Max Scheler in his Man's Place in Nature pointed out the troubled condition of the philosophical study of man: “Man is more a problem to himself at the present time than ever before in all recorded history… We do not have a unified idea of man. The increasing multiplicity of the special sciences, valuable as they are, tend to hide man's nature more than reveal it.” In more recent times, Paul Ricoeur, although approaching the issue from a somewhat different perspective, nevertheless came to a similar conclusion. In his essay The Antinomy of Human Reality and the Problem of Philosophical Anthropology, he stated: “The sciences of man are dispersed into separate disciplines and literally do not know what they are talking about.” It seems to me that part of the explanation for this Situation lies in the way of thinking of Western learning, with its peculiar segmentation of fields of inquiry. During this century, some branches of human sciences, such as psychology, sociology, ethnology, political science, economics and psychoanalysis, have developed rapidly. They deal with the study of man from different angles, and have really accumulated a rich wealth of data. But what man is as such is still not clear. Unless we succeed in forming a comprehensive view of man as a whole, we will not be able to have a real insight into human nature and will be lost in a mass of disconnected and isolated data which seem to lack conceptual unity. We must recognize that the sciences of man in the contemporary Western world belong exclusively to the Western cultural tradition which originated in the early Greek civilization with its own concepts of values. They are entirely divorced from the other great cultures of the world, for instance, the Indian and Chinese cultures, which are as important as the Greek culture in the history of civilization. In order to reach a deeper understanding of man, it is perhaps necessary to make cross-cultural comparative studies. Therefore a short survey of the studies of man in ancient Chinese philosophy may not be superfluous. I would like to confine my survey to the early Chinese philosophers of the pre-Qin period, not only because it is almost impossible to deal with the entire history of Chinese philosophical ideas spanning over two thousand years in an article, but also because the ancient time is the most creative and most important period in the development of Chinese thought.
