 Yablo calls this paradox the \(\omega\)-liar, but others usually refer to it as Yablo’s paradox. Note that none of the sentences \(S_i\) refer to themselves (not even indirectly), but only to the ones that occur later in the sequence. Yablo’s paradox is semantic, but as shown by Yablo (2006), similar set-theoretic paradoxes involving no self-reference can be formulated in certain set theories.
