Unlock the foundations of human knowledge with a classic work on how we come to know what is real.
The final volume of John Locke’s groundbreaking examination asks what knowledge can truly be trusted, how ideas connect to the world, and where certainty ends. It surveys intuition, demonstration, sense, memory, and language to map the boundaries between belief and evidence.
From analyzing the limits of universal propositions to the practical methods that sharpen understanding, this edition guides readers through Locke’s clear-eyed exploration of truth, judgment, and the growth of knowledge. It balances philosophical rigor with accessibility, offering both foundational theories and implications for everyday reasoning and science.
- Discover how different kinds of knowledge are evaluated—intuitive, demonstrative, and sensory.
- See how words and ideas interplay to form meaningful propositions and why some propositions are merely verbal.
- Understand Locke’s view on the improvement of knowledge through comparison of clear ideas and disciplined reasoning.
- Learn how concepts of existence, God, and judgment fit into a broader theory of human understanding.
Ideal for readers of philosophy, logic, and the history of ideas, this edition offers a concise, readable path through a pivotal work on how we know what we know.
