A fundamental goal in many of Foucault's works is to show how that which has traditionally been considered as absolute, universal and true in fact is historically contingent.
This does not, however, lead to epistemological nihilism; rather, Foucault argues that people "always begin anew" when it comes to knowledge.
[4] Foucault incorporated mutuality into his neologism power-knowledge, the most important part of which is the hyphen that links the two aspects of the integrated concept together (and alludes to their inherent inextricability).
In his later works, Foucault suggests that power-knowledge was later replaced in the modern world, with the term governmentality which points to a specific mentality of governance.
One example of the implications of power-knowledge is Google’s monopoly of knowledge, its PageRank algorithm, and its inevitable commercial and cultural biases around the world, which are based on the volume and control principles.
