What is a "paradox"?

A paradox is a statement that seems to contradict itself but often reveals a deeper truth. It challenges logic, common sense, or expectations by presenting two seemingly incompatible ideas that somehow coexist. For example, "Less is more" may appear contradictory, yet it suggests that simplicity can lead to greater effectiveness. Paradoxes are commonly used in literature and philosophy to provoke thought and encourage deeper analysis of complex ideas.
