If the closing price is greater than the opening price, it is called a positive entity, and if the closing price is less than the opening price, it is called a negative entity.

Entity

An important philosophical concept pioneered by the ancient Greek philosopher Aristotle, it is also an important philosophical category used by many philosophers in the history of Western philosophy. Also translated as ontology. Its meaning generally refers to something that can exist independently and is the basis of all attributes and the origin of all things.

The Origin of the Entity Category Ancient Greek philosophy began by exploring the origin of all things. The origin is something that exists independently, from which all existing things are composed, from which they first arise, and to which they finally return. It contains the germ of the category of substance. From Thales to Parmenides, people's understanding of the origin has experienced a process from perceptual concreteness to abstraction. At first, they regarded water as the origin of all things, and finally arrived at the most general and abstract concept of "existence". ". Aristotle summarized the achievements of his predecessors. In "Categories", Aristotle divided "existence" into existence as "this", and existence as quantity, quality, relationship, situation, time, place, etc. *** Category 10. The existence as "this" is called "entity". It is the basis for the existence of several other categories, and the other categories are just its "properties". In this way, starting from Aristotle, "substance" began to be used as a philosophical category.

Aristotle’s basic thoughts on entity Aristotle believes that entity is something that exists independently and is the bearer of all attributes. Linguistically and logically, it is in the position of subject, and other expressions Categories of quantity and quality are attached to entities and are in the position of predicates, and can only be used to explain the subject. He believes that the main characteristics of an entity are: it is "this" rather than "such", it is independent and can exist separately; while maintaining itself unchanged, the entity allows different properties "due to its own changes", such as , the same person can be healthy sometimes and sick sometimes, but still the same person; entity is something that remains unchanged in change and is the basis for change. In this regard, Aristotle clearly stated: "This is the most outstanding sign of substance."

According to these standards, Aristotle believes that individuals, such as this person and this horse, are the most real, primary, and most precise "entities". They are The foundation and main body of everything else. General "genus" and "species" such as "people" and "animals" are second entities. This reflects Aristotle's materialist thought.

However, there are contradictions and confusions in Aristotle's substantive issues. In Volume 7 of "Metaphysics", he decomposes individuals into combinations of matter and form. He believes that matter, form and the individual combination of the two are all called entities in a sense. Strictly speaking, only form, that is, essence, is It is an entity, and the individual composed of form and matter constitutes the second entity.
