Discussing the relationship between the Chinese philosophy (Yin and Yang), and the English literature is rare. The paper introduces John Keats poetry to depict the two poles of the world which are Yin (translated as black). Yang (translated as light or white). But is the world that Keats depicts in his poetry full of gloomy, dull and darkness? Or is it full of happiness, mirth and tranquility? Or is there a balance and equilibrium between the two contrasted worlds?! Just like the depiction of William Blake in Songs Innocence and of Experience. Which are inseparable as Blake says "The Two Contrary States of Human Soul". Where we can clearly see the two forces of (Black and White).
