What Foucault formally describes as arrays, trees, and networks, already existed in geography as spatial analysis (Chorley, 1962; Hagett, 1965) and systems geography (NAS / NCR11 Report, 1965; Harvey, 1969). Also, just as Foucault’s exploration of space should not be understood as an attempt to search for totality or a unique theory of history or society, so in modern attempts of geographers to identify certain ”Foucault” themes should not look for certain universals.
