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.

To mortify and even to injure an opponent, reproach him with the very defect or vice … you feel … in yourself.

Slova - význam

Alfred North Whitehead (19)
… Of course a discussion as to the mere application of a word easily degenerates into the most fruitless logomachy. It is open to any one to use any word in any sense. But …

Aristotelés o matematice | Matematika dle Aristotela | Fysika dle Aristotela | Metafyzika dle Aristotela | Aristotelés o metafyzice | Aristotelés o fysice

Jean Brun (1961)
Les mathématiques traitent des êtres immuables mais non séparés (les figures des êtres immuables par leur essence, mais ils ne sont pas séparés car il n´y a pas de figures séparés de ce dont il y a figure, ni de nombres séparés des choses nombrées; cf. Phys. II 2 193 b 22 sq.); la physique traite des êtres qui on en eux-mêmes un principe de mouvement et qui sont par conséquent des êtres mobiles et séparés les uns des autres; quant à la métaphysique, elle s´occupe de l´Etre immobile et séparé (cf. Méta. E 1 1026 a 13; K 7 1064 a 28).

Protivenství | Resistence

Lucius Annaeus Seneca (-5 - +65)
Epistula LXXVIII.
Toto contra ille pugnet animo; vincetur, si cesserit, vincet, si se contra dolorem suum intenderit. Nunc hoc plerique faciunt, adtrahunt in se ruinam, cui obstandum est. Istud quod premit, quod inpendet, quod urget, si subducere te coeperis, sequetur et gravius incumbet; si contra steteris et obniti volueris, repelletur. …
[Let such a man fight against them with all his might: if he once gives way, he will be vanquished; but if he strives against his sufferings, he will conquer. As it is, however, what most men do is to drag down upon their own heads a falling ruin which they ought to try to support. If you begin to withdraw your support from that which thrusts toward you and totters and is ready to plunge, it will follow you and lean more heavily upon you; but if you hold your ground and make up your mind to push against it, it will be forced back. …]

Vědění (věda) | Pohyb

Aristotelés ()
„If, then, there are any entities or substances such as the dialecticians say the Ideas are, there must be something much more scientific than science-itself and something more mobile than movement-itself; for these will be more of the nature of actualities, while science-itself and movement-itself are potencies for these. „Obviously, then, actuality is prior both to potency and to every principle of change.
(tr. Ross)
Jsou-li tedy určitá jsoucna nebo podstaty toho druhu, jak tvrdí dialektikové o ideách, bylo by něco, co by bylo vědoucí v mnohem větší míře než věda o sobě a co by bylo v mnohem větší míře pohybováno než pohyb o sobě. Neboť toto, vědoucí i pohybované, jsou skutečnosti, ono však, věda a pohyby, jsou jejich možnosti.
Je tedy zřejmo, že skutečnost jest dříve než možnost a každý počátek změny.
