Knowledge Theory, often referred to as Epistemology, is the branch of philosophy that explores the nature, origin, and limits of knowledge. It seeks to answer questions like "What is knowledge?" and "How do we acquire it?" By examining different sources of knowledge, such as perception, reason, and testimony, Knowledge Theory helps us understand how we come to know what we know. One key concept in Knowledge Theory is the distinction between justified belief and true belief. This idea, famously discussed by philosopher Plato, suggests that for a belief to be considered knowledge, it must not only be true but also justified by evidence or reasoning. This framework helps clarify the complexities of understanding and validating our beliefs.
