20th century philosopher Michel Foucault was particularly unusual in his methodology. Rather than concentrate on one subject he sought to gather wisdom from the study of, well, everything. History and more specifically Genealogy were his means to find answers to the concept of the self and the direction of knowledge, which can be structured by the diversification of themes: "... [Genealogy examines] the constitution of the subject across history which has led us up to the modern concept of the self." He viewed genealogy as an inquiry into the seemingly not important, but eventually crucial, parts that constitute a subject and not into the timeless condition of being. Each of these elements are indivisible from the fabric weaved into the current self.
