In their search for truth, contemporary religious believers and modern scientific investigators hold many values in common. But in their approaches, they express two fundamentally different conceptions of how to understand and represent the world. Michael E. Hobart looks for the origin of this difference in the work of Renaissance thinkers who invented a revolutionary mathematical system—relational numeracy. By creating meaning through numbers and abstract symbols rather than words, relational numeracy allowed inquisitive minds to vault beyond the constraints of language and explore the natural world with a fresh interpretive vision. The Great Rift is the first book to examine the religion-science divide through the history of information technology. Hobart follows numeracy as it emerged from the practical counting systems of merchants, the abstract notations of musicians, the linear perspective of artists, and the calendars and clocks of astronomers. As the technology of the alphabet and of mere counting gave way to abstract symbols, the earlier “thing-mathematics” metamorphosed into the relational mathematics of modern scientific investigation. Using these new information symbols, Galileo and his contemporaries mathematized motion and matter, separating the demonstrations of science from the linguistic logic of religious narration. Hobart locates the great rift between science and religion not in ideological disagreement but in advances in mathematics and symbolic representation that opened new windows onto nature. In so doing, he connects the cognitive breakthroughs of the past with intellectual debates ongoing in the twenty-first century.

Hobart demonstrates how Malebranche's theories of truth, ideas, and intelligible extension were formulated under the influence of mathematics and how these theories conflicted with the assumptions and patterns of thought needed for traditional substance philosophy and natural theology. The conflict produced inconsistencies in key concepts--necessity, infinity, being, faith, and reason--rendering any reconciliation between science and religion intellectually unattainable.

The late twentieth century is trumpeted as the Information Age by pundits and politicians alike, and on the face of it, the claim requires no justification. But in "Information Ages," Michael E. Hobart and Zachary S. Schiffman challenge this widespread assumption. In a sweeping and captivating history of information technology from the ancient Sumerians to the world of Alan Turing and John von Neumann, the authors show how revolutions in the technology of information storage--from the invention of writing approximately 5,000 years ago to the mathematical models for describing physical reality in the seventeenth and eighteenth centuries to the introduction of computers--profoundly transformed ways of thinking.
