		現象⊃宇宙⊃性質	Phenomena⊃The Universe⊃Property
§ 1		性質，有利於認識論，非必要於宇宙之運作。	Properties are advantageous for epistemology, but are not necessary for the function of the universe.
§ 2	I	性質，在範疇外不存在，非透過觀察態射，不可描述之。	Any property is non-existent out of a category, and can be described only after observing morphisms.
	II	若干事物共有特定性質，若且唯若存在特定態射使該若干事物經該態射之映射相同。	Things share a certain property, if and only if there is a certain morphism, such that through said morphism the maps of said things are same.
	III	事物，係前項態射定義域之子集合。	A thing is a subset in a certain domain of the morphism in the preceding paragraph.
	IV	映射，係第二項態射陪域之子集合。	A map is a subset of a certain codomain of the morphism in the second paragraph.
§ 3		若干事物經特定性質互相類比。	Things are analogs to each other by properties.
§ 4		本質一詞，視為語言之誤用，在本文中不予考慮。	We shall deem the word "essence" a misuse in language, and shall not consider it in this article.
