 In contrast to Poincaré, Russell 1906 did not consider the actual infinite as an essential component of the foundational malaise, and he stressed that contradictions arise even if the infinite is not involved. This is clearly shown by the Liar paradox in the form ‘I am lying’. As far as we know, it is exactly at this point in time that the (probably) most cited semantical puzzle in the history of logic regains a conspicuous position in logical analysis.
