A "Caesarian," "Augustan," or "Justinian" worldview of theoretical and quantitative geography?

An evolving world view of theoretical and quantitative geography is presented using an analogy from the development of the ancient Roman and Byzantine Empires between Julius Caesar in the first century BC to Justinian in the sixth century AD. This is used to set the discussion platform for a series of papers presented by participants from the early days of quantitative revolution in geography and its transformation into a robust and relevant spatial science. Current theoretical and quantitative geography needs to be, first, active in developing new ideas and applications, second, to continue to transform its methodology to be more societally relevant and scientifically robust and, third, to actively engage cultural critiques of these processes.
