@ARTICLE{Bogusławski_Andrzej_Self-destruction_2019, author={Bogusławski, Andrzej}, number={No 1}, journal={Przegląd Filozoficzny. Nowa Seria}, pages={7-16}, howpublished={online}, year={2019}, publisher={Komitet Nauk Filozoficznych PAN}, publisher={Wydział Filozofii Uniwersytetu Warszawskiego}, abstract={The author argues in favor of a claim concerning a version of radical skepticism that he calls ‘dubitative’. Unlike the radical skepticism once described by Jan Woleński that consists in the skeptic’s total refraining from making any definite statements, ‘dubitative skepticism’ consists in the skeptic’s expression of his/her doubt as regards to whatever he/she is presented with, including his/her own putative statements. ‘Doubt’ equals ‘lack of having a justification’ for a given definitive statement. This attitude is incontrovertibly possible for both a relevant p and a not-p. But ‘doubt about having a justification for p’ is incompatible with ‘doubt about not having a justification for p’. Whatever choice is made in the end, it is contained in the skeptic’s actual statement to the effect that he/she has knowledge concerning something, i.e. a knowledge that concerns his/her state of mind plus the knowledge that he/she has expressed it in the statement itself (and so on, ad infinitum). This extirpates radicalism from the skepticism of a dubitative skeptic, who, as it appears, by no means denounces any commitment to making a statement or to having knowledge. The article closes with an appropriate formal argument expressed in standard terms.}, type={Artykuły / Articles}, title={Self-destruction of skepticism}, URL={http://rhis.czasopisma.pan.pl/Content/110515/PDF/P.Filoz.%201-19%201-A.Boguslawski.pdf}, doi={10.24425/pfns.2019.126631}, keywords={skepticism, contextualism, doubt, ‘he/she knows’}, }
