Epistemology: Key Concepts and Definitions
What is Epistemology?
Epistemology is the branch of philosophy concerned with knowledge, belief, and justification. It explores the nature and scope of knowledge, the different kinds of knowledge, and how we come to acquire knowledge.
Key Concepts
Belief and Justification
Belief is the mental state of accepting something as true or real. Justification is the process of providing adequate reasons or evidence for a belief.
Types of Knowledge
Epistemologists distinguish between different kinds of knowledge, including propositional knowledge, procedural knowledge, and personal knowledge.
Skepticism
Skepticism is the philosophical position that we cannot have certain knowledge about the world. Different kinds of skepticism include global skepticism, local skepticism, and radical skepticism.
Empiricism and Rationalism
Empiricism is the theory that knowledge comes primarily from sensory experience. Rationalism is the theory that some knowledge comes from reason or intuition.
Justification and Truth
Epistemologists are interested in the relationship between justification and truth. A belief can be justified without being true, and a belief can be true without being justified.
Important Information
Descartes' Method of Doubt
Descartes famously employed a method of doubt to challenge what he believed to be certain knowledge. By doubting everything, he aimed to arrive at certain knowledge.
Gettier Cases
Edmund Gettier famously provided counterexamples to the traditional view that knowledge is justified true belief. Gettier cases involve beliefs that are true and justified, but not knowledge.
Science and Epistemology
Epistemology is closely related to science in that it examines the nature and scope of knowledge. Science provides us with many of our beliefs about the world, and epistemology helps us to understand how we justify those beliefs.
