3The study of cities: historical and structural approaches A critical analysis of the replacement of Christallerian ideas about central places by Taylorian ideas about global cities.Taylor has developed his ideas on the basis of a rejection of state-centric and afterwards territorial thinking.The background of my analysis is(i) the rejection of the so-called morphogenetic approach in the pre-positivist urban geography of the first half of the twentieth century(ii) the narrowing down of the field of application of central place theory.
4The study of cities: historical and structural approaches 3. Bobek-Christaller-Barton:rejection of the historial approach of explaining the location of urban settlements by site and situationBobek (1927): urban settlements are nodes in a network of flowsChristaller (1933): (spatial) structureBarton (1978): agency (entrepreneurs)2 kinds of centralityChristallerian analysis as structural approach4. From B.C.B. to P.J.T.Hall (2002): Christaller for a global age↔ Christaller’s theory, Taylor’s conception of the world city network
5The study of cities: historical and structural approaches 5. Pirenne-Jacobs-Taylorthe legitimacy of the concept ‘cities as transhistorical entities’Pirenne, Jacobs: city-based view of history with inter-city relations as the formative forcePirenne: historical approachJacobs, Taylor: structural approachJacobs: transubstantiationTaylor: abstraction6. The structural approach structures the historical approachDetermination of the unit of analysisExample of the archipelago of cities (Abu Lughod)
61. Historical and structural approaches a structural approach relates to the logic of systems,a historical approach relates to:(i) the examination of idiographic causal chains: chains of causes and human purposes and motives, and their intended or unintended results and the possible generalisations or general historical trends that can be deduced from the investigation of these chains,(ii) the actual formation, development and disintegration of systems,e.g.the analysis of the world system by Janet Abu-Lughod
72. The real methodological problem of historiography The use of knowledge of outcomes in the analysis of past eventsE.g. the economic and political hegemony of the West in modern timesexamining ex post factor of this outcome and then reasoning backward, to rationalize why this supremacy had to beconveys the impression that the rise of the West was an inherent historical necessity
82. The real methodological problem of historiography Strategies to avoid the pitfall of historical necessity1. Abu-Lughod:Investigation of a period in which the outcome is still undetermined2. Combination of historical approach and structural approach- Difference between existential necessity and necessary existence- Reasoning backward is a legitimate procedure (retroduction or abduction)- Difference between structural causality and efficient causality
92. The real methodological problem of historiography Strategies to avoid the pitfall of historical necessity2. Combination of structural and historical approachesIn Aristotelian terms:the structural approach should reveal formal causes,the historical approach should reveal efficient and final causes.In present-day language:structure is causally effective, it constrains and enables,agency is causally efficient,human agency is intentionally causally efficient.
10The study of cities: historical and structural approaches A critical analysis of the replacement of Christallerian ideas about central places by Taylorian ideas about global citiesto reveal the implications of the second strategy
113. Bobek – Christaller - Barton Grundfragen der Stadtgeographie (Basic questions of urban geography)“Um städtische Siedlungen hervorzurufen, ist die Zusammenraffung, die Konzentration, die Brechung dieser Verkehrsfäden an gewissen Punkten nötig”“The gathering, the concentration, the breaking of these threads of traffic in certain points is necessary to bring about urban settlements.”In present-day language:“Urban settlements come into being as nodes in networks of flows of traffic.”
123. Bobek – Christaller - Barton Bobek reacted against the morphogenetic approach in urban geography:the description of the site or topographic location of the urban settlement,the description of the situation or geographic location of the urban settlement,the historical development of the urban settlement insofar as it is connected to the site and situationthe urban settlement as part of the broader landscape and as a landscape in itself.Bobek argued that this approach only dealt with superficial characteristics of urban settlements. If geography wanted to say more interesting things about urban settlements, it should focus on their function “als lebendigen Wirtschafskörpers innerhalb des Wirtschaftsgetriebes der Landschaft” [“as living economic bodies within the economic machinery of the landscape”]. Further in the article Bobek extended the notion of traffic to political and cultural communication.
133. Bobek – Christaller - Barton “In dieser Ansichziehung aller früher ungeordeneten Verkehrsfäden, welche sich so wie durch die Wirkung eines Magnetpols zu einem radialen Netze um die städtische Siedlung anordnen, scheint uns das geographisches Faßbare und Wesentliche an städtischer Wirtschaft zu liegen. Den Namen Stadt können nur solche Orte verdienen, welche eine derartige beherrschende Stellung im wirtschaftlichen, kulturellen und politischen Verkehr eines Gebietes besitzen.”“It appears to us that the geographically explicable and essential aspects of the urban economy are to be found in this attraction of all formerly unordered threads of traffic that are organized into a radial network around the urban settlement as if the latter function like a magnetic pole. Only those places that hold such a controlling position in economic, cultural and political communications deserve the name of Stadt (town, city).”

153. Bobek – Christaller - Barton Bobek (1927): network of flowsChristaller (1933): spatial structureChristallers theory meets the requirements of a scientific explanation.Science explains a fact when it is able to establish that the factwas possible at time T1 and place P1, butimpossible at time T2 and place P1, and at time T1 and place P2.This definition of scientific explanation conveys the idea that a fact could not have happened in another way than it actually did, without being inevitable.The method of abstraction is at the origin of the methodological success of Christaller.
163. Bobek – Christaller - Barton Bobek (1927): network of flowsChristaller (1933): spatial structureBarton (1978): agencyThe creation of centrality, AAAGBarton rejects the neoclassical framework in which the received theory of central places is formulated and defends an entrepreneurial/exchange framework based on classical economics.Centrality arises from the activities of the entrepreneur, which can be a merchant, a trader, a retailer, a wholesaler, a banker.
183. Bobek – Christaller - Barton Two kinds of centralitycentrality generated by central functions that serve households (including consumer services, education, administration, and so on) (Christaller)= process of town formation (Taylor)centrality generated by producer services (Barton)= process of city formation (Taylor)
193. Bobek – Christaller - Barton Christaller’s theory as structural approachDistinction between spatial system and system of agents = figurationLogic of a system: the functioning of the system according to the rules of figuration when the agents act completely according to these rulesRules of figuration resulting in the spatial arrangement of central places:- suppliers locate either as closely as possible to each other or as far away as possible from each otherconsumers patronize the nearest central placeRules of figuration to maintain the system of suppliers and consumers(the entire body of rules without which the society concerned would disintegrate)
204. From B.C.B to P.J.T. ↔ Christaller’s theory Hall (2002): Christaller for a global ageDrops the three lowest levels because the settlements concerned have ceased to perform any significant role as central placesAdds two new levels above the L-centres: the global cities and the sub-global cities, which he identifies with the alpha global cities and beta or gamma global cities from the GaWC-classification of global cities.↔ Christaller’s theory↔ Taylor’s conception of the world city network

22Connectivity of cities replaces hierarchy of towns 4. From B.C.B to P.J.T.Connectivity of cities replaces hierarchy of townsChristaller: towns servicing households in a hinterlandTaylor: cities as locations of producer services servicing a hinterworldNevertheless: central placesQuestions about the relation between central places and economic development (growth pole mechanisms and state intervention)To what degree does the key position of producer services entail a coordinating or even organizing role of these services in capital accumulation (global cities and commodity chains)?Question about the legitimacy of the notion of cities as transhistorical entities
235. Pirenne-Jacobs-Taylor TransubstantiationProcedures to neutralize the importance of social classes:Abstraction: Man appears in the shape of Economic ManBanalization: no particular role of social classesTransubstatiation: Man appears in the shape of (Wagnerian) Ecological ManConception of cities as transhistorical entities= variant of transubstantiation (Man appears in the shape of Jacobsian Innovative City Man) ?
245. Pirenne-Jacobs-Taylor Pirenne: Medieval Cities“History is obliged to recognize that, however briljant it seems in other respects, the cycle of Charlemagne, considered from an economic viewpoint, is a cycle of regression. […] The ninth century is the golden age of what we have called the closed domestic economy and which we might call, with more exactidude, the economic of no markets … [T]e period which opened with the Carolingian era knew cities neither in the social sense, nor in the economic sense, nor in the legal sense of the word.”“[T]he ‘abbey-merchants’ were […] not free agents, but employees exclusively in the service of their masters. It is not apparent that any of them ever carried on business on his own account.”European history:Development of commerce by a strong independent middle classCreation of cities with a strong middle class
255. Pirenne-Jacobs-Taylor Jacobs: The economy of cities, The nature of economicsWorld history: Development of networks of cities, economic parentageThe development of forces of production is:not alternately promoted and hindered by the relations of production (Marx)not caused by the development of Man’s creative capacities through his exploitation of the physical environment (Ratzel, Ecological Man)not caused by applying best practices of allocation (Economic Man)but caused by the victory of the innovators in a permanent economic conflict between innovators and conservatives (Innovative City Man)= transubstantitiation
265. Pirenne-Jacobs-Taylor Taylor: Cities within spaces of flows, Cities and statesAbstraction 1: Creating a fiction (Economic Man)Abstraction 2: Focusing on a selected number of qualities of the study object, defined at a certain spatiotemporal levelTranshistorical entitiesPirenne: historical approach, same causes same effectsTaylor: structural approach, moral syndromes = rules of figuration
276. The structural approach structures the historical approach Determination of the unit of analysisWorld city network as interlocking network:Level of the network: world-economyNodal level: cities (local networks of institutions)Sub-nodal level: producer service firmsAgency:Firms, cities, sectors, nation-statesInteraction: causal nexuses, identity assignments
286. The structural approach structures the historical approach Determination of the unit of analysisWorld city network:System of agents: a complex of internally related elements defined at the appropriate level of spatiotemporal abstraction, Wallersteins modern world-system in the ongoing phase of intensified globalizationLogic: the functioning of the network according to the rules of the causal nexuses and identity assignments when the four agents act completely according to these rules Structural approach determines the causal chains to be investigated by the historical approach
296. The structural approach structures the historical approach Determination of the unit of analysisAbu-Lughod: World system in formation (archipelago of cities):Transformation into an integrated world system has not been realized because the subsystems followed their own path of development to such a degree that the trade network was not able to integrate them and fragmentedIn structural terms:The creation of a world-system failed because the systems to be integrated followed their own logic to such a degree that the trade network was not able to develop a logic of its own No system, no subsystems, no unit of analysis, no investigation of commodity chains
306. The structural approach structures the historical approach Determination of the unit of analysisMisleading use of terms:“The term ‘world system’, as it is currently used, has unfortunately been conflated with the particular hierarchical structure of organization that developed from the sixteenth century onward. This makes debates over world systems less than fruitful. It is important to remember that a system is simply ‘a whole composed of parts in orderly arrangement according to some scheme (Oxford Dictionary).”Issue is not similarity to the modern world-system, butexistence of complexes of internal relations between agents exhibiting a logic of their own
