In lieu of an abstract, here is a brief excerpt of the content:Why Maturana?Hans Ulrich GumbrechtWhy would a German scholar specializing in pedagogical thought travel thousands of miles to Santiago de Chile for an interview with a aging scientist who, it seems, has created for himself a solid reputation in the field of "biology of vision" without being hailed by his peers as a path-breaking innovator? In the German intellectual context, the answer to this question could be as laconic as (...) it would be superfluous: it consists in a deictic reference to the name and, implicitly, to the work of Niklas Luhmann. American readers, in contrast, may need some introductory explanation in order to understand the epistemological triangle between contemporary pedagogical thought, Maturana's biology, and Luhmann's philosophy—and, above all, in order to assess and even to appreciate its intellectual potential.Niklas Luhmann is certainly difficult to read, at least for starters, and to those who met him during his lifetime he invariably appeared to be a dead-serious person. But today, more than five years after Luhmann's death, we begin to discover traces of a sometimes uncanny irony—one may want to call it a "practical irony"—in his writing. One of the discursive gestures that characterized Luhmann's texts were references to academic authors who nobody had ever heard of (let alone read), presented with the same seriousness and with the same attitude of intellectual reverence that we normally reserve for the classics: for example, to the logician Gotthart Guenter, the philosopher Fritz Heider, the biologist Humberto Maturana, or the mathematician George Spencer Brown. There is no doubt that, in each case, a specific concept or a specific thought developed by one of these authors had turned out to be truly important within Luhmann's own work, and yet the "effects of authority" that his very serious quotes produced were nothing short of hilarious. For Luhmann's readers, with that self-flagellating attitude in which we academics so like to indulge, quite regularly attributed the experience that they had never heard of those seeming "authorities" to their own lack of intellectual cosmopolitanism. This is why, until the present day, some departments of sociology or philosophy in Germany have Spencer Brown or Guenter specialists on their payrolls, and this also explains why some of those authors have had moments of intense reception [End Page 22] in the world of the humanities and social sciences at German universities. Among them, Humberto Maturana, together with his co-author the late Francisco Varela, seem to be the exception confirming the rule that none of those Luhmann references had the intellectual power to survive Luhmann himself.Now why should one trust Luhmann's trust in Maturana? The debate about the importance of Luhmann's thought (he labeled it a "theory of social systems") in the larger context of contemporary Western philosophy has barely begun to become serious, and we are certainly many years away from a definitive consensual evaluation. But there are two—very different—features about Luhmann's work that make him fascinating at first glance. One lies in the simple fact that, probably, no other thinker since Hegel has managed to develop a restrained set of basic concepts and premises into a systematically coherent philosophical edifice of similar proportions. In this sense, entering the dimension of Luhmann's thought offers the patient reader a possibility to view many familiar positions and questions from sometimes radically different innovative angles. Less obvious, however, and more intriguing is Luhmann's intellectual bet to develop his systemic thought under strict avoidance of notions such as "subject," "subjecthood," or "agency." It was this very bet (about whose existential and political motivations he only left some rather vague remarks) that explains Luhmann's fascination for much theoretical thinking emerging from biological research, above all for Humberto Maturana's work. For from a biological perspective, subjecthood and agency are highly marginal attributes in the realm of living organisms. I believe that this (almost hidden) component in Luhmann's thinking can explain the particularly strong affinity of contemporary pedagogical thought in Germany with his work. Of course, such an affinity will not necessarily lead to a pedagogical theory that, in orthodox reliance on Luhmann, will... (shrink)
