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.

Universita – zralost

Alfred North Whitehead (1948)
About twenty-five years for a man and about three hundred years for a university are the periods required for the attainement of mature stature.
(Harvard: the Future, in: Essays in Science and Philosophy, New York 1948, page 153.)
