LADISLAV HEJDÁNEK ARCHIVES | Cardfile

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.

Metafyzika dle Aristotela | Matematika dle Aristotela | Fysika dle Aristotela | Aristotelés o matematice | 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).

Mathematik Grundlegung

Ludwig Wittgenstein (1937-44)
16. Wozu braucht die Mathematik eine Grundlegung? Sie braucht sie, glaube ich, ebenso wenig, wie die Sätze, die von physikalischen Gegenständen – oder die, welche von Sinneseindrücken handeln, eine Analyse. Wohl aber bedürfen die mathematischen, sowie jene andern Sätze, eine Klarlegung ihrer Grammatik.
Die mathematischen Probleme der sogenannten Grundlagen liegen für uns der Mathematik so weing zu Grunde, wie der gemalte Fels die gemalte Burg trägt.

Kultivace ducha (duše)

Marcus Tullius Cicero (-149)
A. I fit is as you say, have we not mason to fear that you are tricking out philosophy in borrowed plumes? What stronger proof of its uselessness can there bet than to find instances of completely trained philosophers who lead disgraceful lives?
M. That is really no proof, for not all cultivated fields are productive, and the datum of Accius is false:
Though placed in poorer soil good seed can yet
Of its own nature bear a shining crop,
and in the same way not all educated minds bear fruit. Moreover, to continue the same comparison, just as a field, however good the grand, cannot be productive without cultivation, so the soul cannot be productive without teaching. So true it is that the one without the other is ineffective. Now the cultivation of the soul is philosophy; this pulls out vices by the roots and makes souls fit for the reception of seed, and commits to the soul and, as we may say, sows in it seed of a kind to bear the richest fruit /161/ when fully grown. Let us go on then as we have begun; tell me if you will, what subject you wish to have discussed.

Qui est-ce?
C'est une capitale
Avec une Tour Eiffel
Et un pont
C'est une grande capitale
Dans le pays Tchèque
Avec de belles forêts

Kultivace ducha (duše)

Marcus Tullius Cicero (-149)
A. Nonne verendum est igitur, si es ita, ut dicis, ne philosophiam falsa gloria exornes? Quod est enim malus argumentum nihil eam prodesse Guam quosdam perfectos philosophos turpiter vivere?
M. Nullum vero id quidem argumentum nihil est: nam ut agri non omnes frugiferi sunt, qui coluntur, falsumque blud Accii:
Probae etsi in segetem sunt deteriorem datae
Fruges, tamen ipsae suapte natura enitent,
Sic animi non omnes culti fructum ferunt. Atque, ut in eodem simili verser, ut ager quamvis fertilis sine kultura fructuosus esse non potest, sic sine doctrina animus. Ita est utraque res sine altera debilis. Cultura autem animi philosophia est: haec extrakt vitia radicitus et praeparat animos ad satus accipiendos eaque mandat iis et, ut ita dicam, serit, /160/ quae adulta fructus uberrimos ferant. Agamus igitur, ut coepimus. Dic, si vis, de quo disputari velis.
