As an expert in the field of philosophy and metaphysics, I would like to delve into the concept of primary substances as they are understood within the framework of Aristotelian thought. Aristotle, one of the most influential philosophers in history, made significant contributions to the understanding of being and essence, particularly through his concept of primary and secondary substances.
The primary substance, according to Aristotle, is the fundamental entity that exists independently and is not dependent on anything else for its existence. It is the most basic level of substance that underlies all other entities and forms the foundation of reality. In Aristotle's Categories, he discusses the categories of being, and among these, the category of substance is the most important. Within this category, he distinguishes between primary and secondary substances.
Primary substances are individual entities that can exist on their own. They are not predicated of anything else, meaning they do not depend on other entities to be what they are. For Aristotle, primary substances are the subjects of predication, and all other categories (such as quality, quantity, relation, place, time, state, action, and passion) are predicated upon them. They are the ultimate subjects of all categorical statements and are the entities to which all other attributes and properties are related.
In the context of Aristotle's philosophy, an example of a primary substance would be an individual living thing, such as Socrates. Socrates is a unique individual, distinct from all other individuals, and he exists in his own right. He is not a universal, but a particular, and his existence is not dependent on the existence of any other entity. This is why Aristotle refers to him as a primary substance.
Contrastingly, secondary substances are universals that are predicated of primary substances. They are general categories or types that can include many individuals within them. For instance, the term 'man' is a secondary substance because it is a general category that applies to all human beings, including Socrates. It is not an individual entity in itself but rather a classification that encompasses a group of primary substances.
Aristotle's distinction between primary and secondary substances is crucial for understanding his metaphysical system. It helps to clarify the way in which individuals and universals are related and how they contribute to the structure of reality. The primary substance, as the most basic and independent entity, is the starting point for understanding the nature of existence and the various ways in which entities can be categorized and described.
In summary, the primary substance in Aristotle's philosophy is an individual entity that exists independently and serves as the foundational subject of all other attributes and properties. It is the ultimate subject of predication and the basis upon which all other categories are predicated. Understanding the concept of primary substances is essential for grasping the broader Aristotelian framework of metaphysics and the nature of being.

Later in the text, Aristotle calls these particulars --primary substances--, to distinguish them from secondary substances, which are universals and can be predicated. Hence, Socrates is a primary substance, while man is a secondary substance.read more >>
