Assembly Theory and the Third Transition in Science
Before I describe Life as No One Knows It, I need to point out that Sara Imari Walker has achieved something extraordinarily difficult. Despite being a highly credentialed scientist with first class collaborators (including Lee Cronin, Paul Davies and her team at ASU), the task she’s undertaken is a scientific and cultural slalom run.
What she’s attempting in this book is almost impossible. But she does it anyway.
-Cultural and Institutional Resistance
Walker challenges a deeply entrenched narrative that “life is just physics and chemistry.” Media and journals endlessly repeat oversimplified origin-of-life theories. The topic is battle-scarred from debates over religion, philosophy, and meaning.
-Intellectual and Disciplinary Complexity
Physics, biology, information theory, and philosophy each have their own assumptions and gatekeepers. She has no safe camp — too philosophical for hard scientists, too scientific for philosophers.
-Scientific Isolation and Risk
There’s no consensus around life as an informational process. She’s building the plane while flying it. Aligning with any faction (like various evolution groups, ID or strong-AI) risks being pigeonholed or dismissed. In science, speculation outside accepted models risks being labeled fringe — yet explaining life without speculation is impossible. Read more »
