Abstract

“Potentiality and actuality” is among the qualities of the absolute existent, which is the subject of First Philosophy. An existent is “potential” with respect to the actuality it can possess, though it is an “actual existent” by attention to the actuality it now possesses. It should be mentioned that potentiality is an existential thing, however a weak existence which is distinguished from nonexistence. The present essay initially deals with the question how ‘potentiality and actuality’ entered First Philosophy. Then it proceeds to analyze the relation between such an issue and the subject of first philosophy as well as the how of application of existence to it. And finally, the paper propounds some dubious things and then responds to them.
