Urbanization is one of the great trends in the history of homo-sapiens and planet Earth itself, and by the end of this century some three-quarters of all people are expected to be living in cities. This has potentially profound implications for the evolution of humans and the biosphere. As such, urbanization is a rich topic for integral inquiry. An early pioneer of urban planning, Sir Patrick Geddes (1854-1932), developed a school of thought that held striking similarities to integral theory, but he did not have the benefit of drawing upon the integral synthesis that would emerge roughly a century later. Drawing upon a paper published in mainstream scholarly literature, this presentation provides an introductory primer to some of Geddes’ noteworthy “thinking machines,” while assessing correspondence between his work and four important integral themes: Interdisciplinary Holism; Evolution, Development and Complex Systems; Human Agency and Ethics; and Spirituality. In so doing, this presentation hopes to revalorize the work of a somewhat forgotten urban thinker, while elevating urbanism as an important topic for integral inquiry.
