This lucid translation renders Montesquieu's problematic text newly accessible to a fresh generation of students, helping them to understand why Montesquieu was such an important figure in the early Enlightenment and why The Spirit of the Laws was such an influence on those who framed the American Constitution. Fully annotated, this edition focuses on Montesquieu's use of sources and his text as a whole, rather than on those opening passages toward which critical energies have traditionally been devoted. A select bibliography and chronology are also provided.
