The book examines whether Common Sense ideas about an external world can stand up to skeptical challenges.
It surveys Reid’s theory of immediate perception and the ways Hamilton’s influence shapes the debate, weighing them against Hume’s skepticism.
This edition presents a clear, accessible look at how early philosophers argued that we can know external objects directly, and where those arguments fall short. It traces how perceptions, sensations, and beliefs about substance fit together, and it discusses the Law of the Conditioned as a key idea in deciding what we can or cannot know.
- How Reid explains the immediacy of perception and the role of our mental constitution in recognizing external objects
- The critique of Kantian and Reidian influences on Hamilton’s philosophy
- How the debate treats substance versus phenomena and what counts as knowledge of reality
- What the reasoning implies for the idea of a world beyond our minds
Ideal for readers of philosophy and the history of epistemology, especially those interested in common-sense approaches to perception and their challengers.
