Unlike his 2000 volume, Dream of Reason, I don’t have an easy reference for this book. Peter Adamson‘s Without Any Gaps podcast hasn’t got this far yet. AC Grayling’s Age of Genius was structured and focused differently. That’s not to say I’m completely unfamiliar or it’s a completely novel arrangement; but other reviews suggest that this is part of an ongoing debate – defending the value and relevance of older philosophers. Along with this he goes about some mythbusting – showing the commonality between different camps of the enlightenment (although many would disagree, both now and then).
As with his first volume, Gottlieb sees most of these thinkers as rational (at least in part); but he is at his best with the down to earth, practical reasoning of John Locke and Thomas Hobbes. In comparison, the rather more abstract parts of Leibniz or Spinoza feel … well, a bit abstract. Gottlieb seems more comfortable putting them in their social and political situations than he does on their actual writing. Talking of social and political situations – the chapter of Voltaire and Rousseau feels like nothing but that – but Gottlieb seems happy to present them as bickering socialites in the wake of greater thinkers.
Gottlieb presents, chapter by chapter, biographies of a number of the major figures of the enlightenment from Descartes to Hume. The writing is accessible and well judged with a mix of biography, philosophy and occasional dry wit. The topics that run through the enlightenment run through the book: reason, geometry and of course religion. Gottlieb feels more generous than Grayling on the final regard (not too hard). In fact, he seems to have genuine affection for each of these philosophers throughout the book. It’s a solid and well balanced introduction to the context around enlightenment and some of the better known thinkers.
