Reader's Guide
His epistemology was closely tied to his moral philosophy, which emphasized agency and self-control, reminiscent of Roman stoicism. Reid's work influenced later philosophers and, in his day, he was regarded as more important than Hume. His legacy includes a novel mixture of direct realism and ordinary language philosophy, as well as a theory of language distinguishing natural and artificial signs. His ideas remain relevant in discussions of perception, free will, and the foundations of knowledge.

Frequently Asked Questions
What is the Scottish School of Common Sense?
It is the philosophical tradition Reid founded, holding that ordinary human faculties—perception, memory, moral judgment—give us direct, reliable access to the external world without a skeptical intermediary. Reid argued these common-sense principles are foundational and cannot be doubted without self-contradiction.
What is Reid's agent-causal theory of free will?
Reid proposed that a rational agent is itself the efficient cause of its voluntary actions, rather than merely a passive link in a chain of prior events. In his view, genuine freedom requires the mind to be a primary initiator of action, not just a receiver of causal impulses.
How did Reid's rivalry with David Hume play out?
Reid was Hume's most persistent and philosophically serious critic, challenging Hume's skepticism about causation, personal identity, and the external world. Their disagreement became one of the defining intellectual rivalries of the eighteenth-century Scottish Enlightenment.
