Samenvatting van de aflevering

This episode explores the life and scientific theories of Jean-Baptiste Lamarck, focusing on his revolutionary idea that living organisms possess an 'active mechanism' to shape themselves through their environment. Through an interview with historian Jessica Riskin, the discussion contrasts Lamarck's concept of biological agency with the later neo-Darwinist view of organisms as passive machines. The conversation further examines modern scientific evidence for epigenetic inheritance in species like giraffes and mice, noting how these findings may validate some of Lamarck's core intuitions. The episode concludes by reflecting on the political implications of viewing life as passive versus agentic, and the historical rupture between science and the humanities.

00:35:57 · This describes a key experiment demonstrating how traumatic experiences can be passed down through generations in mice.

I take hope from Lamarck's science, from the idea that creative power can't ultimately be controlled or monopolized. It is distributed throughout the living world.

00:53:22 · The speaker explains how the concept of distributed creative agency in biology provides a sense of hope during difficult times.
