Yin and Yang, woman and man, black and white etc., may have been useful classifications. But we should now be aware they are also simplified binary descriptions of the world. And the world is in fact a continuum. We should have a finer understanding and knowledge of this continuum: not only some rough categories, but also all the intermediate states, which may be the most interesting.
There is no precise frontier between Yin and Yang, there is no precise
frontier between you and me.
Il n'y a pas de frontière précise entre le Yin et le Yang. Il n'y a pas de frontière précise entre vous et moi.
