On Reading the Constitution [PDF ebook] 

Our Constitution speaks in general terms of “liberty” and “property, ” of the “privileges and immunities” of citizens, and of the “equal protection of the laws”—open-ended phrases that seem to invite readers to reflect in them their own visions and agendas. Yet, recognizing that the Constitution cannot be merely what its interpreters wish it to be, this volume’s authors draw on literary and mathematical analogies to explore how the fundamental charter of American government should be construed today.
