Here you will find a digitized image of Hejdánek's original filing cabinet. Its total volume is many thousand tickets. We publish them in parts as we handle them. At the moment we have worked out what prof. Hejdánek himself developed electronically. However, much work remains on paper cards. In addition to Hejdánek's extracts from reading, the filing cabinet also includes his own thought work from recent years, which cannot be found elsewhere.
Ludwig Wittgenstein
(1937-44)
21. Unser Verdacht sollte immer rege sein, wenn ein Bewis mehr beweist, als seine Mittel ihm erlauben. Man könnte so etwas ,einen prahlerischen Beweis‘ nennen.
