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.

Zdroje informací – tajné

Alfred North Whitehead (1948)
I do not like this habit among philosophers, of having recourse to secret stores of information, which are not allowed for in their system of philosophy. They are the ghost od Berkeley´s „God“, and are about as communicative.
(Uniformity and Contingency, in: Essays in Science and Philosoophy, New York 1948, p. 108.)

Nelíbí se mi u filosofů zvyk, že se uchylují k tajným zdrojům informací, kterým ve svém systému filosofie nepopřávají místa. Jsou to příznaky Berkeleyho „Boha“ a jsou asi stejně komunikativní.
(Uniformita a kontingence, přel.Fr. Marek, in: Matematika a dobro, Praha 1970, str. 74.)
