How science and philosophy differ – and why they need each otherS

Dorion Sagan, son of Carl Sagan and Lynn Margulis, weighs in on the dialectical relationship between science and philosophy.

The quote appears in the introduction to Sagan's recently published book, Cosmic Apprentice: Dispatches from the Edges of Science, wherein he examines the balance between science and philosophy, while lambasting the authoritarianism of the former and the obscurantism of the latter as "equally formidable obstacles to discovery."
