I recently came across the work of Gotthard Gunther while at the archives of the Biological Computer Lab. at University of Illionois, formerly run by von Foerster.
Two papers of interest in english... http://www.vordenker.de/ggphilosophy/gg_new_approach.pdf http://www.thinkartlab.com/pkl/archive/Cyberphilosophy.pdf Most of his texts are in German but I am still researching: Precursors – Biological Computing Lab “M-valued Logic” – Gotthard Gunther Proposal For a Basic Study of the Semantic and Syntactic Properties of Many-Valued and Morphogrammatic Systems of Logic. 1962 Morphogrammatic Logic “Logic which uses morphograms instead of values as basic operational units might be able to cope with the specific properties of self coding systems of mind-like or mental character.” “The ultimate aim of the cybernetical systems-approach is to design computers as fully self-reflective systems. The theory of resolvable functions suggests that logical relations between individual values do not properly represent the complex characteristics of reflection…This indicates that in order to represent reflection we have to look for a different (and more complex) logical unit. This seems to be the morphogram.” See also http://vordenker.de/contribs.htm - under Gotthard Gunther rudolf kaehr - special non two value logic: http://works.bepress.com/cgi/viewcontent.cgi?article=1015&context=thinkartlab&sei-redir=1&referer=http%3A%2F%2Fwww.google.com%2Furl%3Fsa%3Dt%26rct%3Dj%26q%3Drudolf%2520kaehr%2520-%2520special%2520non%2520two%2520value%2520logic%26source%3Dweb%26cd%3D1%26ved%3D0CCIQFjAA%26url%3Dhttp%253A%252F%252Fworks.bepress.com%252Fcgi%252Fviewcontent.cgi%253Farticle%253D1015%2526context%253Dthinkartlab%26ei%3D-TqHT4feOK2I8gH51NW-CA%26usg%3DAFQjCNGu_-JW00NR_5TIw8X8Qa9GlG3ZRA#search=%22rudolf%20kaehr%20-%20special%20non%20two%20value%20logic%22 Best Bill Bill Seaman Professor, Department of Art, Art History & Visual Studies DUKE UNIVERSITY 114 b East Duke Building Box 90764 Durham, NC 27708, USA +1-919-684-2499 http://billseaman.com/ http://fds.duke.edu/db/aas/AAH/faculty/william.seaman http://www.dibs.duke.edu/research/profiles/98-william-seaman RadioSeaman Paste into itunes (Advanced/open audio streams) for internet radio: http://smw-aux.trinity.duke.edu:8000/radioseaman On Apr 12, 2012, at 8:25 PM, joe.bren...@bluewin.ch wrote: > Dear Pedro, > > Thank you, Pedro, for bringing up the question of logics.
