Abstract
The idea of taiji as the supreme ultimate of the universe has been largely avoided by Chinese philosophers over the past several hundred years, and the same is true of the notions of yin, yang, and qi. The main objection seems to be that these notions operate in a way inconsistent with modern science, but the present essay argues that when we view yin and yang as complements rather than opposites, they can be applied consistently with modern science and in a way that takes in both mental and physical instances. This can lead us to recognize the similarity between the mental and the physical along lines that permit us to revive the notion of qi and treat it as not only in keeping with modern ideas but as also allowing a new kind of validity to the ancient notion of taiji. The West has a lot to learn from a proper modernized account of these concepts, but these are lessons that Westernizing Chinese thinkers also need to learn.
