Abstract: As the representative of the transition period,Nietzsche did an excellent job in developing life aesthetics.He showed us his development to the life aesthetics in three aspects;to rescue life through two different aesthetic state dream and drunk;to reproduce life by the aesthetic standpoint of "for human themselves";to enlarge life with the aesthetic ideal of "Superman".The life aesthetics of Nietzsche indicated his respect to the human desire and also his regard to human's ability.Therefore,his thinking,due to the life connotation,has much more vitality.
