Uncertain Authority.

The article reviews *Magisteria: The Entangled Histories of Science and Religion* by Nicholas Spencer, focusing on the complex and intertwined relationship between science and religion throughout history. Spencer challenges Stephen Jay Gould's concept of "non-overlapping magisteria" (NOMA), arguing that science and religion have been historically entangled rather than separate domains. The book explores diverse historical episodes, including the global spread of European science and the role of Georges Lemaître, a Catholic priest and physicist who proposed the Big Bang theory but cautioned against conflating scientific findings with theological conclusions. While the reviewer finds Spencer's treatment of evolution controversies less engaging and his chapter on artificial intelligence weaker, the work is praised for its nuanced approach to the ongoing dialogue between scientific and religious thought.
