A "philosopher" and quite possibly the father of the current regressive "Social Justice" movement.

You might (rightly) blame Marx for their communism, or some early Feminists for that part of the cancer. But if you talk to a woke academic who thinks that you're "one of them," you'll discover that they're far far more likely to talk about Foucault. He brought a lot of these ideas together and packaged them up under a lens of power and control.

I'll borrow an insightful snippet from Wikipedia:

Foucault's theories primarily address the relationship between power and knowledge [and how the former is used to control and define the latter], and how they are used as a form of social control through societal institutions.
