Nachdem G. Spencer-Brown in der Konstruktivisten-Szene durch H. von Foersters Zitat zum Guru avancierte, wurde er wiederentdeckt und zu einem Lehrauftrag an die Uni Heidelberg eingeladen. 1998 war er als Gastredner am Complex-Change-Kongress der Fachstelle für Weiterbildung der Universität Zürich. "G. Spencer-Brown" ist eine komplexe Figur, die radikal für die "Philosophie" steht, die mit seinen verschiedenen Namen und Darstellungen verbunden ist. Er selbst beschreibt sich als erleuchtet (in: Dieses Spiel geht nur zu zweit). In der Anwendung seines Kalküls erscheint die Erleuchtung als re-entry auf einen Zustand, der zuvor als Geisteskrankheit konstruiert wird. G. Spencer Brown ist ein beautiful mind in der expliziten Form. Mich behandelte G. Spencer-Brown jedenfalls in gröbster Art, als ich anlässlich seines Besuches unserer Veranstaltung in Zürich für drei
Tage auf ihn aufpassen musste, weil er alleine in einer fremden Umgebung krankheitsbedingt nicht klar zu kommen schien. Das war allerdings nur meine Wahrnehmung. Er selbst hatte dazu eine ganz andere Interpretation: Er sagte mir ganz direkt ins Gesicht, ich sei ein ganz normaler Idiot, der seine
eigenen Wahrnehmungen für wirklich nehme.
Jetzt sehe ich in Ihrem mail, dass sich das Muster reproduziert. Wer Aussagen wie "ich habe die Enkelin von Russel vergewaltigt" auf eine Wirklichkeit bezieht, hat von LoF nicht die geringste Ahnung.

I loved you before Through all the Ages
I loved you when The Earth was steamy and damp And when the Earth finally froze I found you still In the ice crystals I loved you in the plains And in trees In the country And in cities In the Moon And under stars In the air And under the sea Through all Time I loved you And everywhere in Space My love created you Breathed life in you And made the deserts bloomSeine aktuelle Adresse ist (bitte in englisch schreiben):

George Spencer-Brown (Pseudonyme: Richard Leroy, James Keys) besuchte das London Hospital Medical College und die Universitäten von Oxford und Cambridge. Mit R.D. Laing erforschte er zehn Jahre lang neue Methoden der Kindererziehung und Therapie. Er ist Gastprofessor an verschiedenen amerikanischen und europäischen Universitäten, hält zwei Weltrekorde als Segelflieger und ist Tarati-Erfinder (das einzige Spiel, das von seiner Schönheit und Tiefe mit Schach vergleichbar ist). Er ist Schachmeister und außerdem Dichter und Songwriter. Gründer und Präsident des Sentinel-Trust, einer Stiftung zur Erforschung und zur Förderung kreativer Erziehung und außerordentlicher Talente. Zahlreiche wissenschaftliche Publikationen über Wahrscheinlichkeit und Logik.

"There can be no distinction without motive, and there can be no motive unless contents are seen to differ value.
"The success of authors such as J M Barrie and J K Rowling depends on the fact that all children know they are magic. No work can be successful unless it in some way confirms some sort of fundamental knowledge that everybody already knows. But to be wildly successful, as these authors are, they must also appear to uphold the popular opinion that magic does not 'really' exist, by making it appear so untrue to life that it obviously cannot happen like this. This fulfils people's common fantasies without upsetting their so-called 'scientific' rationality." (GSB's autobiography ("Volume 1, Infancy and Childhood").

1) New Scientist article (6 Jan. 1977) about proving the 4-color theorem (see p.6): http://books.google.co.uk/books?id=MYRlLL85NUAC&pg=PA1&source=gbs_toc&cad=2#v=onepage&q&f=false
"To apply [LOF] to the four colour theorem he defines two 'distinctions' for the area. If each can be on or off each area can be in one of four states - which can be taken to be four colours. He applies the distinctions to the borders of the areas rather than the areas themselves (which is sufficient for a four-colourable map) and then attempts to prove that any plane map can be composed by drawing two such sets of simple closed curves."
2) http://mywikibiz.com/Directory:Jon_Awbrey/Papers/Propositional_Equation_Reasoning_Systems "This article develops elementary facts about a family of formal calculi described as propositional equation reasoning systems (PERS). This work follows on the alpha graphs that Charles Sanders Peirce devised as a graphical syntax for propositional calculus and also on the calculus of indications that George Spencer Brown presented in his Laws of Form"
3) Peirce and Spencer-Brown: History and Synergies in Cybersemiotics (first two issues of Cybernetics and Human Knowing in 2001; published as a book in 2007) "This special double issue of Cybernetics and Human Knowing is comprised of a collection of papers devoted to the cybernetics and mathematics of Charles Sanders Peirce with a special focus on its synergies with George Spencer-Brown's thinking. Peirce was a truly original American philosopher and logician working in the late 1800s and early 1900s; Spencer-Brown is an English polymath, best known as the author of Laws of Form. The contributions reflect the extraordinary richness of Peirce's work and his relevance to present concerns in cybernetics. The similarities in the focus on some of the deep foundational subjects are astonishing, amongst those especially the concept of the void or Firstness and the continuity of mind and matter."

5) UNCOLORABLE TRIVALENT GRAPHS Author: George Spencer-Brown Cybernetics and Systems, Vol. 29, Issue 4 (June 1998), pp. 319-344
Abstract The text that follows is an extended write-up of the Ross Ashby Memorial Lecture of the International Federation for Systems Research, delivered by invitation to a plenary session of the Thirteenth European Meeting on Cybernetics and Systems Research at the University of Vienna on April 10, 1996. For ease of reading I have retained the informal style of the lecture theater, but without sacrificing accuracy and rigor in my theorems and proofs. Isaacs 1975 detailed a way to make uncolorable 3-graphs. The first part of this communication shows that it is, in principle, the only way and that all such graphs that can define maps must be nonplanar, thus proving the four-color map theorem by exclusion. The second part shows that the method is ineffectual for closed chains of units with a linkage of less or more than 3, so proving that Isaacs found all uncolorable 3-graphs. The associated proof of the map theorem in no way depends on this stronger result but on the fact that chains with a triple or greater linkage, whether colorable or not, cannot be planar. The third part simplifies the Isaacs dot product, proves that his Q class has no more members, and relates the 4-color proof in the first part to the proofs in Appendix 5 of Spencer-Brown 1997.
6) Problems of Form (1999 - 260 pp. - ISBN-10: 0804734232) Edited by Dirk Baecker Translated by Michael Irmscher, with Leah Edwards "Sociology has long sought to find out how acting in a situation and observing that situation may differ and nevertheless belong to a single kind of social operation. George Spencer-Brown's Laws of Form (1969) provides one way to conceive of such an operation. The present book is the first to make sociological use of his mathematical calculus of form, which has been extensively applied to cybernetics, systems theory, cognitive science, and mathematics."
7) The 2008 edition of Laws of Form contains a proof of the Riemann Hypothesis, and two proofs of the 4-Color Map Theorem, with a total of 10 appendices. "It was only on being told by my former student James Flagg, who is the best-informed scholar of mathematics in the world, that I had in effect proved Riemann's hypothesis in Appendix 7, and again in Appendix 8, that persuaded me to think I had better learn something about it."

9) GSB's own website: www.laws-of-form.net Some searching of old versions with archive.org found additional material here, such as a proof of the Riemann Hypothesis.
Of course there are a lot more, but these stood out because they seemed significant to me and were unfamiliar.
