Ivan Soll

Soll completed an essay on Charles Darwin's influence on German philosophy for a volume on Darwin to be published in Turkey, and an essay on Nietzsche's anti-moralism for a conference in Britain in 2010. For the 2010 Summer he taught in Istanbul.

In 2010 he gave the lead-off lecture at a conference in England on Nietzsche's Postmoralism and the keynote address in German, titled Lob der Illusion (In Praise of Illusion), at a conference in Germany.

Soll was a participant in the Peter Sloterdijk lecture series seminar and conference workshop, May 19 to 23, 2008 at the University of Warwick where he discussed the relationship between the philosophies of Sloterdijk and Nietzsche.

Soll contributed three introductions to Walter Kaufmann's Discovering the Mind series of books which were some of the last published works from Kaufmann. Soll has also authored several encyclopedia entries on different topics of philosophy. He continues to be discussed by younger Nietzsche scholars like Bernard Reginster who engaged with his ideas in the 2006 book The Affirmation of Life: Nietzsche on Overcoming Nihilism.

Soll established his reputation among Nietzsche scholars with his 1973 essay "Reflections on Recurrence: A Re-Examination of Nietzsche's Doctrine" which puts forth a novel interpretation of Nietzsche's idea of the eternal recurrence. Soll's interpretation states that the literal possibility of the eternal recurrence is not as important as taking on the idea for what its consequences imply. He argues that the implications of this idea force the individual to evaluate past, current, and future life choices.

Soll taught the majority of his academic career at the University of Wisconsin–Madison. He came to UW-Madison as an instructor in philosophy in 1964, and taught there until his retirement in May 2011. He was promoted to assistant professor in 1966, promoted again to associate professor with tenure in 1969, and to full professor in 1973. He has also held visiting professorships at Justus-Liebig University (Germany), the University of Auckland, and the Boğaziçi University, Istanbul. His philosophical interests include continental philosophy - especially German philosophy, Friedrich Nietzsche, Georg Wilhelm Friedrich Hegel, Arthur Schopenhauer, Jean-Paul Sartre, Albert Camus, and existentialism generally. He also focused on the intersections of philosophy and literature, the history of philosophy, aesthetics, philosophical psychology, and philosophy of life.

Soll was a student of Nietzsche scholar and translator Walter Kaufmann while at Princeton University. Soll completed his A.B. at Princeton University in 1960 with a senior thesis titled "Futility, Freedom and Freud: A Critical Triptych on the Philosophy of Jean-Paul Sartre". He then pursued graduate studies in philosophy at Harvard University, the University of Munich, and Princeton University, where he received his Ph.D. in 1966 with a dissertation titled "Hegel’s Search For Absolute Knowledge".
