人类社会历史的长河不息地向未来奔流。每个时代有每个时代的文明,从简单到复杂,从低级到高级,不断地演进着。自从奴隶社会物质生产和精神生产有了明确的分工,便萌发了科学。人类为了认识与把握周围世界的种种关系,满足日益增长的需要,便分门别类的创建了各个学科,分工越来越细,几乎每一个学科,不同时代对其性质、研究对象都有再认识和重新界定。这是种学研究的深化。比如美学,自1750年德国哲学家鲍姆嘉通的专著《美学》第一卷问世直至现在,关于美学的性质和研究对象,仍然是众说纷纭,甚至还有人提出美学是否要作为一门独立学科存在的质疑。就是在争议中,人们从哲学、伦理学、心理学、艺术学等不同的侧面,深化了美学研究。再如美术,十七世纪在欧洲始用这一名词时,是泛指含有美学情味和美的价值的活动及其产物的。如绘画、雕塑、以及文学、音乐、舞蹈等,以有别于实用艺术。十八世纪后,美术的范围日益扩大,至今一般认为属于美术 The long history of human social history continues to flow to the future.
