Anyway, Foucault was basically of the opinion that every writer needs an “unspoken” tradition or interlocutor. And, of course, there is much resemblance between Spinoza’s Ethics and Foucault’s conception of power as immanent, diffuse, etc. probably in much the same way as his work resembles Weber’s social theory on values and beliefs shaping individual choices in a rational framework – and what constitutes the rational and true in the exercise of human freedom, the processes of subjectification, is the proper object of a political philosophy – such as Foucault’s.

Maybe Weber “stole” from Spinoza too…
