all of this development there had to be close attention to detail; it is the detail which eventually individualizes people. Later in his life, Foucault explained that his work was less about analyzing power as a phenomenon than about trying to characterize the different ways in which contemporary society has expressed the use of power to "objectivise subjects". These have taken three broad forms: one involving scientific authority to classify and 'order' knowledge about human populations; the second has been to categorize and 'normalise' human subjects (by identifying madness, illness, physical features, and so on); and the third relates to the manner in which the impulse to fashion sexual identities and train one's own body to engage in routines and practices ends up reproducing certain patterns within a given society. Literature In addition to his philosophical work, Foucault also wrote on literature. Death and the Labyrinth: The World of Raymond Roussel, published in 1963 and translated in English in 1986, is Foucault's only book-length work on literature. He described it as "by far the book I wrote most easily, with the greatest pleasure, and most rapidly". Foucault explores theory, criticism, and psychology with reference to the texts of Raymond Roussel, one of the first notable experimental writers. Foucault also gave a lecture responding to Roland Barthes' famous essay "The Death of the Author" titled "What Is an Author?" in 1969, later published in full. According to literary theoretician Kornelije Kvas, for Foucault, "denying the existence of a historical author on account of his/her irrelevance for interpretation is absurd, for the author is a function of the text that organizes its sense". Power Foucault's analysis of power comes in two forms: empirical and theoretical. The empirical analyses concern themselves with historical (and modern) forms of power and how these emerged from previous forms of power. Foucault describes three types of power in his empirical analyses: sovereign power, disciplinary power, and biopower. Foucault is generally critical of "theories" that try to give absolute answers to "everything". Therefore, he considered his own "theory" of power to be closer to a method than a typical "theory". According to Foucault, most people misunderstand power. For this reason, he makes clear that power cannot be completely described as: A group of institutions and/or mechanisms whose aim it is for a citizen to obey and yield to the state (a typical liberal definition of power); Yielding to
