Any book who's chapter titles begin with "On" is a must-read for me. This book certainly does not disappoint.
It reminds me, of course, of John Stuart Mill's On Liberty as I expect its meant to do. The first two chapters present opposing pairs: Liberty and Tyranny, Prudence and Progress; I think that from a philosophical perspective they're the best. The next four chapters discuss what America was meant to be about: the Founding, the Constitution, Federalism and the Free Market. This is all good reading and puts you in mind of the ideal of America.
Then Levin discusses the things happening currently that work against those ideals: the Welfare state, Enviro-Statism and immigration. We've been going wrong for a long time. The chapter on Self-Preservation is really pretty much about America's place in the world. The final chapter, A Conservative Manifesto, is fairly short and is actually titled "Epilogue." Having gone this far, one has a good idea of what needs to change in order to bring America back to the path the Founders put it on, but Levin summarizes some specific areas and actions that need to be taken.
A really good read: first on the best seller list for a long time and at this writing still #8 on Amazon's list, on it for almost six months. Highly recommended.
