The author of On Sublime

a bright pearl in the history of aesthetics

is Longinus in the 3rd century rather than Longinus in the 1st century. Instead of belonging to pure rhetoric or pure aesthetics

his Sublime implicates the transition from rhetoric to aesthetics and the unity of the two. The judgment of On Sublime is not the logical judgment of seeking truth or the rational development of the character in the text

but a judgment of value or emotional experience and understanding of the meaning in the text. Therefore

in an all-sided and systematic way

we should understand and judge the implication of the Sublime of Longinus from the angle of the whole text and development history in western aesthetics

especially the evolution history of the aesthetic scope and concept.
