8 Spatial Fixes, Temporal Fixes and Spatio-Temporal Fixes Bob Jessop It is especially productive to probe major thinkers on issues central to their work and widely regarded as their strong points. Accordingly, my contri- bution reviews Harvey’s concern with the spatialities and temporalities of capitalism and capitalist social formations. Harvey is famous for stressing the importance of spatiality for an adequate historical materialism. If one phrase symbolizes this, it is surely ‘spatial fix’. He has also shown how capi- talism rests on a political economy of time and has explored the dynamics of time-space compression in both modern and postmodern societies. More recently, he has introduced the term ‘spatio-temporal fix’ to decipher the dynamics of capitalist imperialism and its grounding in the interac- tion between capitalist and territorial logics of power. These interests are reflected in his successive but overlapping accounts of three interrelated fixes: spatial, temporal and spatio-temporal. Each works in its own way to defer and/or displace capitalism’s inherent crisis-tendencies but does so only by subsequently intensifying these tendencies and their effects. My chapter affirms Harvey’s key contributions on these themes but also suggests that they have significant ontological, epistemological, methodological and sub- stantive limitations. It also proposes a potentially more productive reading of the spatio-temporal fix that is none the less consistent with and, indeed, inspired by his approach. Harvey on Methodology, Dialectics and Internal Relations Harvey’s work on spatial fixes is obviously rooted in his long-standing interest in land-use patterns and locational dynamics, spatial forms, spatial justice and urbanism, and his later sustained engagement with Marx’s
