In russian edition of "Filozofia przipadku" I found very strange statement about novel "The name of the rose" by U.Eco. When Lem analyses hero's reasoning he note, that it's similar with Wittgenshtein theory appeared
half of centure later.
But action take place in 14 century!
This mistake is repeated later.
Do you know is it Lem's mistake?May be, it's only misprint?
