1. A statement that, despite apparently valid reasoning from true premises, leads to a seemingly self-contradictory or logically unacceptable conclusion.
This definition emphasizes the logical contradiction that paradoxes create. They often involve seemingly true premises that, when combined, produce an absurd result. Examples include the classic liar's paradox ("This statement is false") or Zeno's paradox of motion.
2. A situation, person, or thing that combines contradictory features or qualities.
This definition highlights the paradoxical nature of the subject itself. It may have seemingly incompatible characteristics, making it difficult to understand or categorize. Examples include the "noble savage" concept, where a person is both primitive and virtuous, or a "sweet-sour" flavor.
Ultimately, the best definition depends on the specific situation. You might need to consider the context, the purpose of the definition, and the desired level of detail. However, both of these definitions capture the essence of a paradox: a seemingly illogical or contradictory element that challenges our understanding and makes us question our assumptions.
