Hume and Empiricism: A Shift in Modern Philosophy
Hume and the Rise of British Empiricism
David Hume, like Immanuel Kant, is considered a key figure in modern philosophy, although he belongs to the 18th century, specifically to the Enlightenment. Hume represents a significant philosophical current of the modern age called British Empiricism, a trend opposed to Rationalism. While these two schools of thought have opposing viewpoints, they share some common ground, such as subjectivism.
Descartes and the Foundation of Modern Philosophy
René Descartes, a rationalist, initiated a radical shift compared to the prevailing trends of his time. Before Descartes, faith was considered the primary instrument of knowledge, while science and technology remained in the background. The texts of Plato and Aristotle were treated as sacred, and the dominant philosophy was a reworking of these texts. Descartes was the first to question Christianity, earning him the title of the founder of modern philosophy. He challenged the old religious and objectivist assumptions, establishing a metaphysical system based on reason.
Locke and the Introduction of Empiricism
John Locke later introduced empiricism, asserting that the ultimate foundation of philosophy was not reason but experience. Empiricism, similar to Locke’s, had appeared throughout the history of philosophy. For instance, Aristotle proposed it as a method of knowledge. However, when we speak of empiricism today, we primarily refer to the second major philosophical movement of the Modern Age: English empiricism, represented by Hume and Locke.
Key Tenets of Empiricism
This trend stands in opposition to philosophical rationalism. It is based on the following principles:
- The senses are the primary instrument of knowledge.
- Innate ideas are denied because they are not acquired through sensory experience.
- Human knowledge is limited by sensory experience.
Empiricism’s View on Reason and God
Empiricism proposes a new concept of reason, entirely different from that of rationalism. Reason becomes dependent on and limited by experience. However, reason remains the only tool humans have for acquiring knowledge. Empiricists advocate for a practical reason focused on morality, ethics, and politics, rather than a speculative reason engaged in metaphysics, as the latter is not grounded in experience.
Hume’s Denial of God’s Existence
Hume also disagrees with preceding philosophers regarding the existence of God. While both Descartes and other rationalist and empiricist thinkers had affirmed God’s existence, arguing that God must be the cause of our ideas about Him, Hume refutes this. He believes that this “causal relationship” is invalid since we have no direct impressions of God. According to Hume, causal relationships are only valid between ideas and the impressions from which they originate. Therefore, since our idea of God is not derived from any impression, God’s existence is denied.
Kant’s Synthesis
Later, Immanuel Kant developed a theory that synthesized rationalism and empiricism. He believed that both philosophical movements have validity in explaining reality.
