A paradigm is offered for understanding the interlocking modes of doto analysis that have come to characterize geography as a result of its recent "quontitotive revolution." Among the most serious new problems to emerge have been those related to autocorrelation in spatial series. Two cases are discussed: spatial point processes in the plane, and generalized contiguity in continuous spatial series. In both cases the stationarity assumption is questioned, and on alternalive formulation using diffusion theory is proposed.
