Re: [-empyre-] self-modification, emergence



Here is exactly the program of the conferences under the leadership of the
Biologist JJ Kupiec at Ecole normale Supérieure ( anglophone :
http://www.ens.fr/index_en.php ) , but with anglophone researchers, it is to
give you an idea of the net in matter of theses critical phylosophical
discussions as actual and active in the objective condition of current new
Sciences. Please once more: I apologize of my stupid writing French to
English (another way is a bit better:)

Center of research Jean Cavaillès (
http://www.cavailles.ens.fr/ )(Mathematics researcher from this School who
resisted as a heroe dying without telling a name of his fellows under the
torture by nazis ) in Paris, from october 2003 to June 2004 :

Textes fondateurs de la biologie (Texts founders of the biology)
Responsable : Jean-Jacques Kupiec.
http://www.cavailles.ens.fr/annonces.html

Because they are in a fight against reductionist viewes in Science... (they
are the object of hard attacks by education authorities in the power) but so
much researchers have signed the manifesto to renew the vision and method in
matter of Aids and Cancer, just this year, now (specially US/ CA) that
thanks to them it would become to emerge here and there. (But what of them
front of God at the power in USA right now?)...

Quote:

" Un groupe de travail a été constitué pour travailler sur des textes
fondateurs de la biologie datant du 20ème siècle. La participation est libre
mais puisqu'il convient de lire les textes pour prendre part à ce groupe de
travail, un contact avec Jean-Jacques Kupiec est nécessaire. Séances prévues
:
15 Octobre 2003, B. Chamak : sur Cybernetics (toujours à 13h30 au 29, rue
d'Ulm, 3ème étage droite)
19 Novembre, E. Witt : sur La Critique de la faculté de juger
17 Décembre, T. Heams sur : Qu'est-ce que la vie?
21 Janvier 2004, J .Segal:  sur la Théorie mathématique de la communication
11 Février, M. Morange sur : On growth and form
17 Mars, C. Imbert : sur Goldstein
28 Avril, C. Galperin sur : Problems of Embryology
26 Mai, A. Barberousse sur : Les principes de la systématique
16 Juin, A. Fagot Largeault, : Introduction à la médecine expériementale "
