In 1980, Michel Foucault began a vast project of research on the relationship between subjectivity and truth, an examination of conscience, confession, and truth-telling that would become a crucial feature of his life-long work on the relationship between knowledge, power, and the self.
These series of lectures here will give an insight to his lifelong work, and - into the idea of self. He argues that it's not about the self that we're discovering, but how to change it.
