Model Answer
0 min readIntroduction
Empiricism, as a philosophical tradition, asserts that knowledge originates primarily from sensory experience. Rejecting the rationalist emphasis on innate ideas, Empiricists like John Locke, George Berkeley, and David Hume sought to understand the world through observation and experimentation. Central to their investigations was the concept of ‘Substance’ – a fundamental underlying reality believed to support qualities we perceive. However, Empiricists grappled with the notion of Substance, questioning its knowability and ultimately offering radically different interpretations, challenging the traditional metaphysical understanding of it as an independent, enduring entity. This answer will explore these varying perspectives.
Locke’s Conception of Substance
John Locke, in his *Essay Concerning Human Understanding* (1689), distinguished between ‘primary’ and ‘secondary’ qualities. Primary qualities (e.g., solidity, extension, shape) are inherent in objects themselves and are perceivable. Secondary qualities (e.g., color, taste, smell) are powers in objects to produce sensations in us. Locke argued that we perceive these qualities, but the ‘substratum’ or ‘Substance’ *supporting* these qualities remains unknown. We assume a Substance exists to explain the coherence of these qualities, but we cannot directly perceive it. This Substance is a necessary, but ultimately unknowable, entity.
Berkeley’s Idealistic Revision
George Berkeley, a staunch Empiricist, took a radical step in his *A Treatise Concerning the Principles of Knowledge* (1710). He rejected Locke’s notion of an unknowable Substance. Berkeley famously argued “*esse est percipi*” – to be is to be perceived. For Berkeley, there is no material Substance existing independently of perception. Objects exist only as ideas in the minds of perceivers, and these ideas are caused by God. Thus, Substance, for Berkeley, is not an independent entity but God himself, the ultimate perceiver who ensures the continued existence of things even when no finite mind is perceiving them.
Hume’s Skeptical Demolition
David Hume, in his *A Treatise of Human Nature* (1739-1740), pushed Empiricism to its skeptical limits. He questioned the very notion of causation and the existence of an external world. Hume argued that we only experience a constant conjunction of qualities, not a necessary connection between them. The idea of Substance, he claimed, is a product of custom and habit. We are accustomed to seeing certain qualities together, so we infer the existence of an underlying Substance, but this inference is not justified by experience. Hume concluded that Substance is nothing more than a bundle of perceptions, and the belief in its existence is a natural, but ultimately unfounded, illusion.
Comparative Analysis
The Empiricists’ treatment of Substance reveals a progression from a cautious agnosticism (Locke) to a subjective idealism (Berkeley) and finally to a radical skepticism (Hume). Locke retained a belief in an external reality, albeit an unknowable one. Berkeley eliminated the unknowable aspect by identifying Substance with God. Hume, however, dismantled the concept altogether, reducing it to a psychological habit.
| Empiricist | Concept of Substance | Key Argument |
|---|---|---|
| John Locke | Unknowable substratum of qualities | We perceive qualities, but not the underlying Substance. |
| George Berkeley | God as the ultimate Substance | To be is to be perceived; Substance is the perceiver (God). |
| David Hume | Bundle of perceptions | Substance is a product of custom and habit, not justified by experience. |
Implications and Challenges
The Empiricists’ critique of Substance had profound implications for metaphysics and epistemology. It challenged the traditional view of a stable, enduring reality and paved the way for more subjective and relativistic accounts of knowledge. However, their views also faced challenges. Critics argued that Hume’s skepticism was self-refuting and that Berkeley’s idealism relied on an unproven assumption about God. Locke’s unknowable Substance, while avoiding the pitfalls of idealism and skepticism, was accused of being an empty concept.
Conclusion
In conclusion, the Empiricists’ exploration of Substance represents a pivotal moment in the history of philosophy. While each – Locke, Berkeley, and Hume – offered a distinct interpretation, they all shared a commitment to grounding knowledge in experience and a skepticism towards metaphysical speculation. Their critiques of the traditional concept of Substance forced a re-evaluation of fundamental assumptions about reality, knowledge, and the limits of human understanding, leaving a lasting legacy on subsequent philosophical thought.
