Bruno Latour (French: [latuR]; born 22 June 1947) is a French philosopher, anthropologist and sociologist. He is especially known for his work in the field of science and technology studies (STS). After teaching at the Ecole des Mines de Paris (Centre de Sociologie de l'Innovation) from 1982 to 2006, he became Professor at Sciences Po Paris (2006-2017), where he was the scientific director of the Sciences Po Medialab. He retired from several university activities in 2017.

Latour's work Nous n'avons jamais ete modernes : Essais d'anthropologie symetrique was first published in French in 1991, and then in English in 1993 as We Have Never Been Modern.  Latour encouraged the reader of this anthropology of science to re-think and re-evaluate our mental landscape. He evaluated the work of scientists and contemplated the contribution of the scientific method to knowledge and work, blurring the distinction across various fields and disciplines.  Latour argued that society has never really been modern and promoted nonmodernism (or amodernism) over postmodernism, modernism, or antimodernism. His stance was that we have never been modern and minor divisions alone separate Westerners now from other collectives. Latour viewed modernism as an era that believed it had annulled the entire past in its wake. He presented the antimodern reaction as defending such entities as spirit, rationality, liberty, society, God, or even the past. Postmoderns, according to Latour, also accepted the modernistic abstractions as if they were real. In contrast, the nonmodern approach reestablished symmetry between science and technology on the one hand and society on the other. Latour also referred to the impossibility of returning to premodernism because it precluded the large scale experimentation which was a benefit of modernism.  Latour attempted to prove through case studies the fallacy in the old object/subject and Nature/Society compacts of modernity, which can be traced back to Plato. He refused the concept of "out there" versus "in here". He rendered the object/subject distinction as simply unusable and charted a new approach towards knowledge, work, and circulating reference. Latour considered nonmoderns to be playing on a different field, one vastly different than that of post-moderns. He referred to it as much broader and much less polemical, a creation of an unknown territory, which he playfully referred to as the Middle Kingdom.  In 1998, historian of science Margaret C. Jacob argued that Latour's politicized account of the development of modernism in the 17th century is "a fanciful escape from modern Western history".
