Callebaut WernerThe Werner Callebaut Prize is named in honor of Werner Callebaut (1952–2014), whose untimely death in 2014 inflicted a serious blow to the philosophy of biology community worldwide.

The award is intended to advance the careers of younger scholars working at the intersection of the fields represented by the ISHPSSB, and is awarded to the best manuscript utilizing an interdisciplinary approach based on a presentation at one of the two previous ISHPSSB meetings by someone who was, at the time of presentation, a graduate student.

Werner's mentorship and guidance has benefitted the intellectual and personal development of countless philosophers and scientists over the last twenty years, and contributed greatly to making sure that philosophical and scientific work evolve in constructive dialogue and reciprocal respect. His work reached creatively across fields of relevance to the philosophical understanding of biology (comprising areas as far removed as economics, evolutionary biology, history, sociology and cognitive science), as well as across national cultures, languages and traditions (most notably the ‘continental-analytic’ divide among philosophers of science), hence making a prize focused on interdisciplinarity most appropriate, especially for ISHPSSB.

The award consists of a certificate and US$500, as well as a permanent record of the award on a plaque which circulates every two years to the current winner(s). The prize has been made possible through the generosity of individual donors and of the Konrad Lorenz Institute for Evolution and Cognition Research (KLI) for financial support.


Submissions should be in the form of a paper prepared for submission to a professional journal, with an indication of the journal in question, along with a brief statement detailing the interdisciplinarity represented in the manuscript. An electronic copy, in Microsoft Word or PDF format, should be emailed to the Chair of the Callebaut Prize Committee. Submissions can be simultaneously considered for the Marjorie Grene and the Werner Callebaut prizes, but a paper may not be awarded both prizes. The committee reserves the right not to make an award, or to split the award.

Information on the next call for nominations will be circulated and available here. Links to the respective citations can be found in the table of recipients.
