Abstract

In the arduous discussion of the principality of existence or the principality of essence, it is necessary first to examine the proposition which is the cornerstone of this discussion; second, it should be discussed how its conception can cause its acknowledgement; then we can clarify the significance of existential proposition; and finally, setting forth the meanings of the word “existence” and those of the word “essence” or “quiddity”, it would appear the signs of confused discussion of epistemology and ontology.
