Building a foundational understanding of the digital, Logic of the Digital reveals a unique digital ontology. Beginning from formal and technical characteristics, especially the binary code at the core of all digital technologies, Aden Evens traces the pathways along which the digital domain of abstract logic encounters the material, human world. How does a code using only 0s and 1s give rise to the vast range of applications and information that constitutes a great and growing portion of our world?Evens' analysis shows how any encounter between the actual and the digital must cross an ontological divide, a gap between the productive materiality of the human world and the reductive abstraction of the binary code.
