Primary substances are the fundamental entities in Aristotle's metaphysics, referring to individual things or particular objects that exist independently. They serve as the foundation for Aristotle's ontology, distinguishing between what is unique and concrete versus what is general or abstract, such as species or universals.

Review Questions

• How do primary substances differ from secondary substances in Aristotle's philosophy?
  • Primary substances are individual entities that exist independently, such as a specific horse or tree. In contrast, secondary substances are the species or genera that describe these individuals, like 'horse' or 'tree,' which do not exist on their own but rather categorize the primary substances. This distinction is crucial for understanding Aristotle’s overall metaphysical system and how he categorizes reality.
• Discuss the significance of primary substances in Aristotle's theory of categories and how they relate to his concept of essence.
  • Primary substances are central to Aristotle's theory of categories because they form the foundational building blocks of his ontology. They represent individual entities that have their own unique essences—qualities that define their identity. Understanding primary substances allows one to see how these individual entities interact with broader categories and how essence plays a role in determining what those entities are.
• Evaluate the role of primary substances in explaining change and permanence within Aristotle's metaphysics, particularly in relation to his views on substance.
  • In Aristotle’s metaphysics, primary substances play a critical role in explaining both change and permanence. While primary substances represent what exists concretely and can undergo change, their essence remains constant even as they experience various changes over time. This relationship helps Aristotle to account for how individual entities maintain their identity despite changing attributes, providing a coherent framework for understanding the dynamics of existence.
