Don’t be misled. The liberalism that the author speaks of is the classical variety that undergirds both conservative and progressive liberal thought. The liberalism the author believes has failed is that of Mill and Locke, the latter a big influence on our Founding Fathers.
I heavily annotated my copy of Why Liberalism Failed because it is the kind of book that makes you think in fresh ways about old ideas.
Much ink has already been spilled debating the merits of this book. I won’t go into detail on those since this brief review is designed to say that I find Deneen’s thesis quite compelling. I plan to read more of Mill and Locke so my view could change some, but right now, I find myself aligning with Deneen’s concerns.
