Liberty's Grid: A Founding Father, a Mathematical Dreamland, and the Shaping of America
A birdās eye view of the U.S. reveals perpendicular streets, rectangular fields, and uniformity in both urban and rural landscapes. "Libertyās Grid" examines how this gridded landscape came to exist. It explores how the work of Isaac Newton and RenĆ© Descartes shaped Thomas Jeffersonās ideas. It also shows how grids produced a backlash in favor of non-gridded landscapes. This book is well suited for both scholars and students and is highly recommended.
Amir Alexander begins Libertyās Grid by considering the view of the San Fernando Valley from Castle Peak, a hill near his home. Although the Valley is peculiar in many respects, when viewed from the top of a 600-foot hill, it is easy to see the gridded landscape that matches other U.S. urban areas. āThe street plan of the Valley, Alexander asserts, is āthe street plan of Americaā (3). By this, he means that streets in cities across the U.S. offer rectilinear uniformity: ābroad, arrow-straight avenues, regularly spaced and perfectly parallel to one another, are met at fixed intervals by equally straight and parallel streets that intersect them at precise right anglesā (3). Rectilinear streets were not a U.S. invention, but they have become so prevalent that they āseem like components of a single, all-encompassing urban grid stretching from New York City to Chicago to Los Angelesā (3). Grids are not particularly practical or utilitarian, Alexander contends, and they generated significant resistance. However, Jefferson championed the grid, which embodied āan ideal of America as a land of unconstrained freedom and infinite opportunityā (8).
Alexander begins long before the Sage of Monticello was born and explores how RenĆ© Descartes and Isaac Newton influenced Jeffersonās thinking. In November 1619, Descartes spent a consequential day and night in an inn near Ulm, where he transformed himself āfrom a restless young man into a systematic philosopherā (21). Descartesās conclusions led to the idea that āspace is mathematical, and everything within itāevery location, every object, every shape, and every movementācan be precisely described through mathematicsā (22). Descartes revised the Aristotelian cosmos, and his universe matched the one we know today, but with one difference: āits space was completely full, allowing no gaps of emptiness to exist between different bodiesā (25). As Descartes revised Aristotle, Newton revised Descartes. Newtonās mathematics assumed that āgeometrical objects exist in an absolute mathematical spaceāuniform, universal, and infiniteā (43).
Jefferson embraced the concept of absolute space and applied it to the land. He frequently āinsisted that America was a vast and empty virgin territoryā (84) and that the American West was a āvast and all but limitless spaceā (85). Scholars have noted the problematic tendency among people throughout American history, including Jefferson, to see the land as empty space, a perspective that erases Indigenous people. Nevertheless, Jefferson saw America as a blank slate and the embodiment of the Newtonian absolute space. Jefferson also formulated a simple yet audacious rectilinear grid plan as he thought about how to survey, divide, and settle this allegedly empty land. The Confederation Congress accepted Jeffersonās vision when they passed the Land Ordinance of 1784 and imposed āa vast mathematical grid on western landsā (126). Jefferson seemingly won this debate because, as Alexander notes, āto a stunning degree, the western United States had become precisely what Jefferson had dreamed it would be: a vast uniform and undifferentiated space, marked by a vast uniform mathematical gridā (153).
Jeffersonās plan, although it triumphed in some ways, attracted scorn and criticism in others. Jefferson and Pierre Charles LāEnfant had very different visions for Washington, D.C. LāEnfant wanted a Euclidean landscape like Versailles. Jefferson, unsurprisingly, preferred a rectilinear grid. LāEnfant denounced Jeffersonās plans as ādefective,ā ātiresome and insipid,ā and the product of āsome cool imagination wanting a sense of the really grand and truly beautifulā (173). Jefferson lost that battle. He seemed to win in New York City, until, of course, one arrives at Central Park, the ultimate rebellion against the grid. Urban parks, suburbs, campuses, and national parks all, in their way, rebuke the grid.
This is a fascinating book about mathematics, space, and place, as well as how grids both order and disrupt the lives of many people in the modern U.S. It will work well in upper-level undergraduate courses and graduate seminars.
