 Foucault deploys genealogy to create what he calls a “counter-memory” or “a transformation of history into a totally different form of time” (Foucault 1977, 160). This entails dissolving identity for the subject in history by using the materials and techniques of modern historical research. Just as Nietzsche postulates that the religious will to truth in Christianity results in the destruction of Christianity by science (see Nietzsche 1974 [1882], 280–83), Foucault postulates that genealogical research will result in the disintegration of the epistemic subject, as the continuity of the subject is broken up by the gaps and accidents that historical research uncovers. The first example of this research is Histoire de la folie à l'age classique, published in 1961, the full version of which was published in English as History of Madness in 2006. Here, Foucault gives an account of the historical beginnings of modern reason as it comes to define itself against madness in the seventeenth century.  His thesis is that the practice of confining the mad is a transformation of the medieval practice of confining lepers in lazar houses. These institutions managed to survive long after the lepers disappeared, and thus an institutional structure of confinement was already in place when the modern concept of madness as a disease took shape. However, while institutions of confinement are held over from a previous time, the practice of confining the mad constitutes a break with the past.
