Lambert Schmithausen

• 1. Introduction

  ›

  Lambert Schmithausen was born on the 17th of November 1939 in Cologne, Germany, and went on to become one of the most methodical voices in Buddhist scholarship. He earned his doctorate in philosophy from the University of Vienna in 1963, at an age when many of his peers had barely settled on a field. That early immersion in Viennese philosophical training shaped everything that followed.

  His career would stretch across two major German universities, accumulating a body of work so wide in scope that it touches ancient Sanskrit manuscripts, the question of whether plants can suffer, the ethics of war, and the origins of nonviolence as a concept. How does a scholar trained in European philosophy end up excavating the mental architecture of eighth-century Indian Buddhism? And what drove him, decade after decade, to return to questions about nature, sentience, and what living things owe each other?

• 2. Two Universities, One Career

  ›

  Schmithausen arrived at the University of Münster as an associate professor of Indology in 1970. The move placed him in Germany's academic mainstream at a time when Buddhist Studies was still finding its footing as a discipline separate from broader Indological inquiry.

  Three years later, in 1973, he transferred to the University of Hamburg, where he would remain for the rest of his active career. Hamburg gave him a platform for the long, slow work that defined his scholarship: close textual analysis of primary sources in Sanskrit, Tibetan, and Chinese, pursued across decades rather than a single productive burst. He retired from Hamburg in 2005, a span of thirty-two years at a single institution. In 1995, midway through that Hamburg tenure, the Austrian Academy of Sciences elected him a Corresponding Member, a recognition that crossed national lines to acknowledge his centrality to the field.

• 3. The Yogacara Project

  ›

  The Yogacara school of Indian Buddhism occupies a demanding corner of the field. Its texts probe how consciousness works, what perception actually delivers, and whether there is anything outside the mind at all. Schmithausen committed a significant portion of his career to untangling its history and vocabulary.

  His two-volume study "Alayavijñana: On the Origin and Early Development of a Central Concept of Yogācāra Philosophy" appeared in Tokyo in 1987, published by the International Institute for Buddhist Studies as part of the Studia Philologica Buddhica Monograph Series. The alayavijñana, or storehouse consciousness, is one of Yogacara's most contested ideas: a kind of subliminal current beneath ordinary awareness that carries the seeds of future experience. Tracing its origin and early development required reading across dozens of texts, identifying which ideas were borrowed, which were invented, and in which order they crystallized. That 1987 work remains a reference point for anyone working on the same territory.

  Earlier, in 1969, he had published a detailed study of the Nirvana section within the Yogācārabhūmi, one of the tradition's foundational compilations, also through the Austrian Academy of Sciences. A later essay, published in 2007 in the Journal of the International College for Postgraduate Buddhist Studies in Tokyo, examined aspects of spiritual practice in early Yogacara, showing that his engagement with the tradition never closed.

• 4. Plants, Animals, and the Ethics of Nature

  ›

  A strand running through Schmithausen's work that surprises many readers is his sustained attention to the status of plants in early Buddhist thought. Whether plants are sentient, whether they can suffer, and what moral weight that might carry are questions he returned to multiple times across his career.

  In 1991, he published two separate works on this theme. One was a full monograph, "The Problem of the Sentience of Plants in Earliest Buddhism," issued by the International Institute for Buddhist Studies in Tokyo. The other was a lecture he had delivered as the A.L. Basham Lecture for 1989 at the Australian National University in Canberra, published under the title "Plants as Sentient Beings in Earliest Buddhism." That the same subject warranted both a monograph and a named lecture series shows how seriously scholars were taking the question. A third contribution in 1994, "On the Status of Plants in Earliest Buddhism," appeared in the proceedings of an international conference in Bangkok and Los Angeles.

  His broader engagement with nature as an ethical category produced "Buddhism and Nature" in 1991, first as a lecture at EXPO 1990 in Japan and then as an enlarged version with notes. He also tackled the question of violence in Buddhist ethics, examining war, meat-eating, and the concept of ahimsa across several essays. A 1999 essay in a volume on violence in South Asian cultural history addressed Buddhist attitudes toward war. A 2000 essay in the same volume addressed the case for vegetarianism. The concept of ahimsa itself, the ethical commitment to nonharming, received dedicated attention in a 2000 essay tracing its origins, published in a volume honoring Professor Minoru Hara.

• 5. Languages, Manuscripts, and Philological Precision

  ›

  Schmithausen's essays frequently appear in German and Japanese as well as English, and several of his works exist in multiple translated versions, including a Japanese translation of his essay on equanimity and compassion, rendered by Naoki Saito and published in the journal Tetsugaku in 2002. A second Saito translation followed in 2003.

  His philological work included analyses of manuscript fragments, a painstaking form of scholarship that requires identifying fragmentary texts, establishing their relationship to known sources, and interpreting damaged or incomplete passages. Two notes on fragments from the Jñānaprasthāna, an Abhidharma text, appeared in festschrift volumes in 1997 and 1998. A 2002 contribution with Jens Braarvig and Lore Sander examined fragments held in the Schøyen Collection in Oslo. His earliest publications, from the 1960s, engaged with perception theory in Indian philosophy, examining figures such as Salikanatha and Prasastapada in the Wiener Zeitschrift für die Kunde Süd- und Ostasiens.

  The breadth of languages involved, Sanskrit, Tibetan, Chinese, Pali, German, Japanese, English, meant that Schmithausen's scholarship operated across traditions that most specialists treat as separate fields. His 1965 monograph on Mandanamirsa's Vibhramavivekah, a study in Indian error theory, was published by the Austrian Academy of Sciences when he was still in his mid-twenties, suggesting that the range was present from the beginning.

• 6. A Career's Reach

  ›

  By the time Schmithausen retired from Hamburg in 2005, his list of publications spanned more than four decades, ranging from short notes in specialist journals to book-length investigations of core Buddhist concepts. His final monograph in the list, a study of the external world in the Cheng wei shih lun, appeared in Tokyo that same retirement year.

  The audiences he addressed shifted across that period. Some of his essays appeared in festschrift volumes honoring individual scholars, contributions to the collegial exchange that holds academic fields together. Others were delivered at international conferences and then revised for publication. Still others were commissioned pieces for volumes bringing Buddhism into dialogue with Christian theology or with environmental philosophy. His contribution to Bron Taylor's Encyclopedia of Religion and Nature in 2005 placed Buddhist perspectives on nature within a reference work designed for readers far outside the specialist community.

  One thread that connects the end of his career to its beginning is the Austrian Academy of Sciences, which published his first monograph in 1965 and whose recognition as a Corresponding Member came in 1995. The academy's Sitzungsberichte series appears in his bibliography across three separate decades, a small institutional continuity running beneath the larger arc of his work. His 1997 study of maitri, the Buddhist concept of loving-kindness, and its relation to danger in nature was published in that same series, volume 652.
