Zollikon Seminars

The Zollikon Seminars were a series of philosophical seminars delivered between 1959 and 1969 by the German philosopher Martin Heidegger (1889–1976) at the home of Swiss psychiatrist Medard Boss (1903–1990). The topic of the seminars was Heidegger's ontology and phenomenology as it pertained to the theory and praxis of medicine, psychology, psychiatry and psychotherapy. The protocols of the seminars, along with correspondences between Heidegger and Boss, were published in German in 1987 under the title Zollikoner Seminare, Protokolle- Gersprache- Briefe Herausgegeben von Medard Boss (note 382 pages). The English version of the text was published in 2001 (360 pages). Note the later German publication of the HGA 89. Zollikoner Seminare, (2017) is 880 pages and more complete. The complete HGA 89 Table of Content is here.

Background

Boss was a psychoanalytic psychiatrist trained within the framework of natural scientific medicine. During active military duty as a field doctor during World War II (which "all Swiss men who were not psychologically impaired were required to do"), Boss read Heidegger's dense and often complicated text, Being and Time. He initially remarked that he "understood almost none of its content". Yet, as a psychiatrist, Boss was captivated by the ideas, which he evaluated as "fundamentally new, unheard of insights into the human being's way of existing in the world", and was intrigued by the author. Following World War II, Boss inquired about Heidegger, at which he was informed about Heidegger's participation in the Nazi Party and was discouraged from entertaining Heidegger's philosophy. However, Boss attempted to distinguish between Heidegger's philosophy and Heidegger's character, and, after evaluating the former, decided to write Heidegger a letter. In 1947, Boss wrote Heidegger, asking him to clarify some of his philosophical ideas. To Boss's surprise, Heidegger replied. For the next twelve years, Boss and Heidegger corresponded about by mail and personal visits. Boss, though, "did not feel it proper to be the only one benefitting from frequent meetings with a great thinker." With Heidegger's permission, Boss opened up their discussions with colleagues and students, beginning the Zollikon Seminars.

The Seminars

The Zollikon Seminars were conducted intermittently, "two to three times per semester", between 1959 and 1969. Boss noted that Heidegger dedicated three hours a night, two nights a week to the task, and typically spent the day before preparing the lectures. Typically, fifty to seventy of Boss's psychiatric colleagues and students were invited to the lectures.

The first seminar was on 8 September 1959 in the auditorium of the Burghölzli Clinic at University of Zurich. Heidegger included in his introductory lecture a brief explication of Da-sein, "the basic constitution of human being" as "being-in-the-world". He also offered to the students a radical diversion from conventional Cartesian epistemology, namely "all objectifying representations of a capsule-like psyche, subject, person, ego or consciousness in psychology and psychopathology must be abandoned in favor of a new understanding." Boss observed at this time that the modern, technological conveniences of the lecture hall were ill-fitting for Heidegger's thought, so the remainder of the seminars were held at Boss's home.

The first lecture was documented only as a result of Heidegger's notes. The lectures given between 1960 and 1964 do not appear to have been recorded; they are absent from the Zollikon Seminars text. The subsequent lectures, given between 24 January 1964 until the end were transcribed verbatim (though possibly not in their entirety) or condensed.

Boss observed that the initial sessions were extremely difficult. He likened Heidegger's attempt to discuss his philosophy with medically trained doctors and students "as if a man from Mars were visiting a group of earth-dwellers and trying to communicate with them." Boss also noted that many of Heidegger's questions about the human being (and the human kind of being), existence, space, time, and so on were answered with prolonged periods of silence, or worse, "shock or even outrage" that the questions were being asked in the first place. As late as 1964, even Heidegger still conceded difficulty. In the lecture dated 9 July 1964, Heidegger said, "The last seminar rather was a failure. However, the difficulty lies in the subject matter itself...which is being itself." Yet, Boss was consistently sympathetic to Heidegger's task, which he described as "Sisyphean, of "giving my friends, colleagues, and students a sound philosophical foundation for the medical practice." Neither Heidegger nor the seminar students "grew tired" of the material and worked to "achieve a common ground" in their thinking.

Afterword

The last of the Zollikon Seminars was held in July, 1969. Boss observed that with his "conscience as a doctor" he could no longer expect Heidegger, growing in age and declining in physical ability, to prepare and participate in the seminars. Boss and Heidegger agreed to continue corresponding via mail, and Boss visited Heidegger's home in Freiburg as both their schedules allowed. In one of his last documented letters (dated 21 February 1971), Heidegger congratulated Boss on an award granted him by the American Psychological Association. He also encouraged Boss to continue with many of the ideas discussed in the seminars and suggested several of his own texts, but also dissuaded Boss from reading any of "the literature on Heidegger". After that, Heidegger retired to his Black Forest cabin and "limited his visits and letters." Heidegger died in 1976, though before his death he contributed to and edited Boss's text Existential Foundations of Medicine and Psychology, published in 1979. Boss died in 1990.

But are the connections between psyche and soma something psychological, something somatic, or neither one or the other? We wind up in a dead end, which shows you better than anything else how essential the question of method is.

In Greek and medieval thought, the concept of an object and of objectivity did not yet exist. Objectivity is a definite modification of the presence of things...Modern science rests on the transformation of the experience of the presence of beings into objectivity.
