TY - JOUR T1 - Paradox Kréťana a metóda prípustných situácií A1 - Snoha, Ľubomír A1 - Snohová, Daniela JA - Obzory matematiky, fyziky a informatiky Y1 - 2003 VL - 32 IS - 2 SP - 1 EP - 10 SN - 1335-4981 N2 - A method is described which can successfully be used in a classroom to show that the so called paradox of the Cretan (Epimenides, the Cretan, declared: ”All the Cretans are liars.”) is not a logical paradox in fact. When compared with the usual short argument, the method needs some more time to get the result but seems to be more appropriate for pupils aged 12–15. The method is said to be the method of admissible situations. ER -
