Self referential statements can be paradoxical as known since ancient times. (Some of this basic paradoxes had immense impact on my own field -mathematics.) Of course, paradoxical self-referential statement plays a role also in humor. The following conversation artually took part in a department meeting two decades ago.
L: Some people in the department think that they are wiser than what they really are
J: I am really wiser than what I think I am.
J's statement seems paradoxical, and it looks different than the common ones known to me. Is it?
