Important Philosophers | – Aristotle – René Descartes – Immanuel Kant – G.W.F. Hegel – Martin Heidegger – Bertrand Russell – David Lewis – Alfred North Whitehead – Willard Van Orman Quine |
Key Concepts | – Ontology: The study of being and existence. – Identity and Change: Questions about what it means for something to remain the same over time. – Causality: Examining cause and effect relationships. – Possibility and Necessity: Exploring what could exist versus what must exist. |

Category | About Epistemology |
Definition | The study of knowledge—how we know what we know, including questions about its acquisition, justification, and truth. |
Key Questions | – What is knowledge? – How do we acquire knowledge? – What are the limits of our knowledge? – How can we distinguish between true knowledge and mere belief? – Is certainty possible? |
Important Philosophers | – Plato – Aristotle – René Descartes – John Locke – David Hume – Immanuel Kant – G.W.F. Hegel – Edmund Husserl – Martin Heidegger – W.V.O. Quine |
Key Concepts | – Knowledge vs. Belief: Differentiates justified true belief from mere belief. – A Priori vs. A Posteriori: Knowledge independent of experience vs. knowledge derived from experience. – Skepticism: Challenges assumptions about what we can know. – Justification: How we justify beliefs through foundationalism, coherentism, or reliabilism. |
Relevance Today | – Science: Understanding how we validate scientific theories. – Education: Best practices for teaching and learning. – Artificial Intelligence: Examining if machines can possess knowledge. —Ethics: How knowledge shapes moral decision-making. |
Example | The impact of misinformation on knowledge. In an age of rapid information sharing, philosophers explore how we can distinguish credible sources from unreliable ones and whether true knowledge can be attained amidst widespread skepticism. |
