Abstract: In his “Letters of Aestheical Education”,Siller points out:Aesthetics i rooted in the depth of human nature,it is the object of game impulse which is the combination of perceptual impulse and rational impulse resulted from interraction of human character and human nature. these ideas have synthesized in a direct way the two aesthetic trends of continental rationalism and British empiricism,inherited Cante's aesthetic thought,and opened the way for Hegel to combine into one epistemolgical aesthetics,noumenon aesthetics and dialectial aesthetics.They are typical of Siller's aesthetical anthropology thought and are imbued with the same spirit of Marx's practical aesthetics.

Key words: Siller, aeshetics, perpetual impulse, rational impulse, game impulse
