"Present quantity" is an important category of China's classical aesthetics. As an aesthetic category, its mother lies in Buddhist philosophy. This category itself has experienced the evolution from Buddhism to aesthetics. Wang Fuzhi, a thinker and writer in the late Ming and early Qing Dynasties, formally put forward the aesthetic category of "present quantity". The theory of "present quantity" is a very important part of Wang Fuzhi's aesthetic thought system.

The word "present quantity" is a category in the Buddhist theory of only knowing and reasoning. To correctly understand Wang Fuzhi's theory of "present quantity", we must first clarify the concept of "present quantity".

The original meaning of "quantity" refers to measurement and is extended to measurement and estimation. Tang Kui Ji's "On the Thin Volume of Reformed Classics in Ming Dynasty" said: "Commentators. Quantity also. Also. " Accordingly, it can also be said: "those who measure, discuss, and discuss." In short, "quantity" involves people's understanding of things. "Quantity" refers to people's understanding of things or methods of understanding things. There are three common quantities, namely, present quantity, specific quantity and non-quantity. Mei Guangxi's Compendium of Xiangzong said: "Those who measure three things mean that today's quantity is not quantity. Measured by the heart of a king, there are three different appearances of the heart. Both the current quantity and the specific quantity are just quantitative knowledge, and the non-quantitative knowledge is the wrong quantitative knowledge. " According to Ding's Dictionary of Buddhism, proper "quantity" can be divided into "three quantities (present quantity, specific quantity and holy teaching quantity)", "four quantities", "five quantities" and "six quantities", but other "quantities" can be absorbed in and included in the present quantity and the specific quantity.

What is "cash flow"? According to the theory of "justness", "there is no difference in quantity. If there are different meanings, such as wisdom and color, they will not be reflected, so the name is now measured. " Mei Guangxi's "A Compendium of Xiangzong" has a good explanation for this:

If there is no difference, there are different kinds of famous sayings. When it comes to cyan, if it comes to cyan's famous sayings, their famous sayings can be applied to all cyan, that is, they cannot be attached to their own things. That is, the * * * stage of various laws has been opened. This is not the current quantity.

The same is true for all kinds of people, and they are also * * * phase changes, so they are not present quantities. If we say that the self is three degrees in mind, it is said that there is no difference, but there is no difference between ears.
