Skepticism is an approach that involves questioning the validity of claims and beliefs. It encourages individuals to seek evidence and reason before accepting something as true. This critical thinking process is often applied in various fields, including science, philosophy, and everyday decision-making. In philosophy, skepticism challenges the certainty of knowledge, suggesting that what we believe may not always be accurate. This perspective can lead to deeper inquiry and understanding, as it promotes a careful examination of information rather than blind acceptance.
