Jonathan Leighton

Executive Director

Jonathan founded OPIS in 2016 and brings a mixture of rationality and creativity to his passion of helping to prevent suffering in the world. A research molecular biologist by training, Jonathan holds an AB from Harvard University and a PhD from the University of Basel. He spent several years in industry before turning to writing and public speaking on ethics and compassion. He is the author of a new book titled The Tango of Ethics: Intuition, Rationality and the Prevention of Suffering (2023), which develops a more holistic approach to ethics based on phenomenological experience and the urgency of suffering, and The Battle for Compassion: Ethics in an Apathetic Universe (2011), which methodically addresses the question “What matters?” He also produced a short film to communicate some of the key ideas from his first book. @JonLeighton1

He wrote Naître est-il dans l’intérêt de l’enfant? Idéologie de reproduction versus non-souffrance (2011), the result of a decades-long historical exploration of the conflict between the ethic of non-suffering and the ideology of reproduction. In 2013 he co-founded the Algosphere Alliance, a network and direct democracy for the alleviation of suffering.
