At its core, epistemology is concerned with defining what it means to "know" something. Historically, philosophers have often defined knowledge as "justified true belief." This classic view holds that for someone to know a proposition, it must be true, they must believe it, and they must have sufficient justification for that belief. However, challenges to this definition have led to new theories about knowledge, suggesting that there may be more to understanding than simply having belief grounded in truth.
The importance of epistemology extends beyond abstract theory. In daily life, we rely on knowledge to make decisions, solve problems, and navigate our understanding of the world. Whether it is scientific research, moral reasoning, or even personal belief systems, the way we define and assess knowledge influences how we engage with reality. Epistemological questions therefore shape not only philosophical discussions but also practical outcomes in various fields such as education, science, and politics.
