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.


Alfred North Whitehead (1941)
… I venture upon one remark which applies to all philosophic work: – Philosophy is an attempt to express the infinity of the universe in terms of the limitations of language.
… Dovolím si jednu poznámku, jež se týká veškeré filosofické práce: – Filosofie je pokus vyjádřit nekonečnost vesmíru omezenými výrazy jazyka.
