Even a superficial look at the classical ideas and practices of government of populations makes it immediately apparent that there is a peculiarity in Foucault’s genealogy of western bio-politics and governmentality. According to Foucault, western governmental rationality can be traced back to the Judeo-Christian tradition in general and to the Christian ideology and practice of the pastorate in particular.

With the rise of Christianity, the majority of these classical practices, including negative eugenics and even family policies, either faded into the background or they were rejected outright.
