Skolem's paradox, a Common card

The card carries these facts from its Wikipedia article.

• The paradox arises from part of the Löwenheim–Skolem theorem, Thoralf Skolem was the first to discuss the seemingly contradictory aspects of the theorem, and to discover the relativity of set-theoretic notions now known as non-absoluteness.
• Although it is not an actual antinomy like Russell's paradox, the result is typically called a paradox and was described as a "paradoxical state of affairs" by Skolem.
• In model theory, a model corresponds to a specific interpretation of a formal language or theory.
