Through collective reasoning the polis has recognised that reliance on pure deduction is dangerous. Such citizens are free to explore the Truth Mines containing not just the records of human experience, but the mathematical implications of that experience ‘experienced’ by its fellow-citizens. Moving from the self-referential algorithms necessary to produce consciousness, to the algorithms of transformational topology necessary to impose that consciousness on the world coherently, he provides step by step instructions for the evolution of primitive pyschoblasts, embryonic minds as pure bits of energy, into citizens of the polis, an entirely electronic civilisation. One of those flaws, perhaps the most destructive, is the vulnerability of the universe to arbitrary and uninformed divine intervention.Įgan lays out a blueprint for how a very different form of life than has been previously known comes into existence. In fact, this is a history of how the defects and design flaws of the original creation story are corrected by hard experience. Only one comparison seems even remotely appropriate - to the biblical Book of Genesis.ĭiaspora is a history of the re-creation of the universe, one in which there is no need for divine power to either start it off or continue its development.
