Michel Foucault's Force of Light offers a comprehensive, chronological reading of Foucault's published, and many unpublished, writings. James Bernauer claims that Foucault's achievement was to have fashioned a series of inquiries that makes it possible to question the activity of thought itself as an ethical practice. Foucault's ethic historicizes Kant's great questions on knowledge, obligation, and hope. He asks not "What can I know?" but rather "How have my questions been produced? How has the path of my knowing been determined?" Not "What ought I to know?" or "What may I hope for?" by "How have the parameters of my aspirations been defined?"
