A statement which appears self-contradictory or contrary to expectations, also known as an antinomy. Curry uses the term pseudoparadox to describe an apparent paradox for which, however, there is no underlying actual contradiction. Bertrand Russell classified known logical paradoxes into seven categories. Ball and Coxeter give several examples of geometrical paradoxes.
