Transformation of Western Aesthetic Attitude and Criticism Criterion since the 18th Century

Throughout human history,transformation of aesthetic attitude always led to changes in art criticism criterion.To Kant and Greenberg,beauty means purity,order,and nobility.However,Grunge aesthetic in 1990s began to include things kitsch and ugly into the category of beauty.Past unilateral aesthetic criticism has been becoming more and more contemporary,multifarious,and comprehensive.Onone hand,such transformation displays the evolvement of human consciousness which underwent from unconsciousness to consciousness and then to an advanced development of unconsciousness and conscious-ness in a whole new and contemporary cultural context.On the other hand,such transformation is also a dialectic process of creating new art forms conforming to continually advancing consciousness.Why do human aesthetic attitudes change with time? Since beauty is not an objective thing,but it is an aesthetic feeling,so it is rather subjective.The truth of beauty lies in people's aesthetic judgment.Aesthetic consciousness,which guides people to find themselves,and it embodies freedom and life meaning,will continue to greatly impact people's daily life,behavior and attitude.
