An examination of the relation between war and politics, by one of the
twentieth century's most influential thinkers
From 1971 until 1984 at the Collège de France, Michel Foucault gave a
series of lectures ranging freely and conversationally over the range of
his research. In Society Must Be Defended, Foucault deals with the
emergence in the early seventeenth century of a new understanding of war
as the permanent basis of all institutions of power, a hidden presence
within society that could be deciphered by an historical analysis.
Tracing this development, Foucault outlines the genealogy of power and
knowledge that had become his dominant concern.
