Over the past twenty-five years, Bruno Latour has developed a research protocol different from the actor-network theory with which his name is now associated-a research protocol that follows the different types of connectors that provide specific truth conditions. These are the connectors that prompt a climate scientist challenged by a captain of industry to appeal to the institution of science, with its army of researchers and mountains of data, rather than to "capital-S Science" as a higher authority. Such modes of extension-or modes of existence, Latour argues here-account for the many differences between law, science, politics, and other domains of knowledge.

"Magnificent... An Inquiry into Modes of Existence shows that [Latour] has lost none of his astonishing fertility as a thinker, or his skill and wit as a writer... Latour's main message-that rationality is `woven from more than one thread'-is intended not just for the academic seminar, but for the public square-and the public square today is global as never before.
-Jonathan Ree, Times Literary Supplement

"Latour's work makes the world-sorry, worlds-interesting again."
-Stephen Muecke, Los Angeles Review of Books
