Homonym: Skeptic (Doubt)
A skeptic is someone who questions or doubts accepted beliefs, claims, or ideas. They often seek evidence and logical reasoning before accepting something as true. Skepticism can apply to various fields, including science, philosophy, and religion, where individuals critically evaluate information rather than accepting it at face value.
In philosophy, a skeptic may challenge the certainty of knowledge, as seen in the works of René Descartes or David Hume. In everyday life, skeptics might question popular trends, conspiracy theories, or unverified information, promoting a more analytical approach to understanding the world around them.
