The Concept of Substance
Overview
In philosophy, substance is a fundamental concept that has been debated and refined over centuries. A substance is primarily what cannot be predicated of or present in another thing without existing independently. This concept has undergone significant development, with various philosophers contributing to its understanding.
Context
The concept of substance emerged within the framework of ancient Greek philosophy, particularly in the works of Aristotle. The Aristotelian tradition emphasized the importance of distinguishing between substances and accidents, which are attributes that can be separated from a subject. This dichotomy laid the groundwork for later philosophers to explore the nature of substance.
Timeline
- Ancient Greece: Aristotle’s Metaphysics introduces the concept of substance as a primary entity.
- Medieval Period: Aristotle’s influence spreads throughout Europe, shaping the development of scholasticism and the understanding of substance.
- 17th Century: René Descartes’ Meditations on First Philosophy critiques Aristotelian metaphysics, introducing a new perspective on substance as a thinking, non-extended entity.
- 18th Century: Immanuel Kant’s Critique of Pure Reason redefines the concept of substance in terms of appearances and noumena.
- Late 19th-Early 20th Centuries: Analytic philosophers like Bertrand Russell and G.E. Moore challenge traditional notions of substance, introducing new theories on the nature of reality.
Key Terms and Concepts
- Substance: An individual thing or entity that exists independently.
- Predicable: A property or attribute that can be predicated of a subject without existing independently.
- Present in a subject: A property or attribute that is inherent to a subject, but not part of its essence.
Key Figures and Groups
- Aristotle: Developed the concept of substance as a primary entity in his Metaphysics.
- Scholasticism: A medieval philosophical movement influenced by Aristotle’s ideas on substance.
- Rene Descartes: Introduced the concept of thinking, non-extended substance in his Meditations on First Philosophy.
Mechanisms and Processes
The primary sense of substance implies that it is what cannot be predicated of or present in another thing without existing independently. This can be broken down into three steps:
- A subject (e.g., a piece of grammatical knowledge) has attributes that are inherent to its essence.
- These attributes are not predicable of the subject, meaning they do not exist independently.
- Therefore, the substance is what remains after separating these attributes from the subject.
Deep Background
The concept of substance is deeply connected to the development of Western philosophy, particularly in the areas of metaphysics and epistemology. The distinction between substances and accidents was a central concern for philosophers like Aristotle and his followers. This dichotomy led to debates about the nature of reality and how we can know it.
Explanation and Importance
The concept of substance is crucial for understanding various philosophical theories, including:
- Essentialism: The idea that objects have inherent properties or essences.
- Nominalism: The view that abstract entities like species and genera are mere labels.
- Materialism: The philosophy that matter is the fundamental reality.
Comparative Insight
The concept of substance can be compared to other philosophical ideas, such as:
- Kant’s Noumena: Kant argues that our understanding of substances is limited to appearances, which are influenced by our cognitive faculties.
- Hegel’s Absolute: Hegel introduces the idea of absolute spirit as a unified, all-encompassing substance.
Extended Analysis
The Relationship Between Substance and Predication
In the primary sense of substance, it is what cannot be predicated of another thing. This raises questions about the nature of predication itself. Can we truly separate substances from their attributes?
The Implications of Secondary Substance
The concept of secondary substance, where species or genera are considered substances, has been criticized for leading to bad metaphysics. However, this view can be seen as a way to understand how abstract entities relate to individual things.
Substance and the Nature of Reality
The concept of substance is deeply connected to our understanding of reality. If we consider substances as primary entities, what does this say about the nature of objects and their attributes?

- How does the secondary sense of substance impact our understanding of abstract entities like species and genera?
- In what ways can we reconcile the primary and secondary senses of substance?
Conclusion
The concept of substance is a fundamental idea in philosophy, with a rich history spanning centuries. From Aristotle’s development of the primary entity to modern philosophers’ critiques and redefinitions, substance has remained a central concern for thinkers seeking to understand reality and its nature.
