Urban knowledge is strongest when the city is allowed to act inside the method. A street, plot, park, route, threshold, darkness, conversation, map or bodily hesitation is not merely the location at which research happens; it is part of the apparatus through which urban reality becomes perceptible. Situated urban knowledge names this epistemic condition. It replaces the image of an observer standing outside the city with a field of transactions in which bodies, forms, instruments, histories and representational technologies continuously modify what can be known. Moudon’s morphology provides one foundation for this position because urban form is understood through buildings, plots, streets and open spaces as historically transformed and mutually dependent elements rather than static geometries.
