Abstract
This paper intends to improve and enrich the contents of the basic theory of appreciation-ology by means of reexamining the article, "The Act of Appreciation," written eighteen years ago by the same author. The introduction of this paper describes the context and motive in which appreciation-ology was conceived. After reconfirming the validity of the three aspects of an appreciative act, detailed analysis is made concerning these aspects, that is, "seeing", "knowing" and "thinking". After this reexamination, the distinctive features of appreciation-ology and the possibilities of appreciation-ology are described. In conclusion, some considerations about appreciation are made in a context broader than that of art education.
