  This is a paper for a special issue of the journal "Studia Semiotyczne"
devoted to Stanislaw Krajewski's paper [30]. This paper gives some
supplementary notes to Krajewski's [30] on the Anti-Mechanist Arguments based
on G\"{o}del's incompleteness theorem. In Section 3, we give some additional
explanations to Section 4-6 in Krajewski's [30] and classify some
misunderstandings of G\"{o}del's incompleteness theorem related to
Anti-Mechanist Arguments. In Section 4 and 5, we give a more detailed
discussion of G\"{o}del's Disjunctive Thesis, G\"{o}del's Undemonstrability of
Consistency Thesis and the definability of natural numbers as in Section 7-8 in
Krajewski's [30], describing how recent advances bear on these issues.
