"We are using philosophical criteria in choosing our models. A lot of cosmology tries to hide that."

George Ellis is a South African cosmologist and philosopher of science renowned for bridging the gap between physics and metaphysics. Collaborator of Stephen Hawking on The Large Scale Structure of Space-Time, Ellis later turned his attention to the limits of scientific reductionism—arguing that human consciousness, meaning, and morality cannot be explained by physics alone.

He has authored several books and more than 500 articles, including his 2016 book How Can Physics Underlie the Mind?, in which he calls for a major conceptual shift in biology and physics to grapple with the mysteries of consiousness. His research spans cosmology, complexity, and the philosophy of science, making him a leading voice in debates over the relationship between science and human values.
