jim; I'd like to amplify last night's post. Early in his recommendable book; Tao, the Watercourse Way Alan Watts says; "At the very roots of Chinese thinking and feeling there lies the principle of polarity, which is not to be confused with the ideas of opposition or conflict. In the metaphors of other cultures, light is at war with darkness, life with death, good with evil and the positive with the negative, and thus an idealism to cultivate the former and be rid of the latter flourishes throughout much of the World.
To the Chinese way of thinking, this is as incomprehensible as an electric current without both positive and negative poles, for polarity is the principle that + and -, north and south, are different aspects of one and the same system, and the disappearance of either one of them would be the disappearance of the system."
