While this book centers around the Scientific Revolution, it truly surveys sets out to survey two thousand years of dominant epistemologies where the Scientific Revolution provides the greatest change. The author traces similarities in thoughts from the pre-socratics to Aristotle to Aquinas' scholasticism to the scientific process. If this sounds boring to you, trust me: the author's knack for lucid explanations and impassioned analysis on the concrete effects of these thoughts makes the story actually enjoyable to read.
Keep in mind, the book's audience is people desiring a better understanding of history, not in-depth philosophy. As any student of history would want, more attention is paid to the impacts of the scientific process rather than the precise interplay between induction and deduction, for instance. This ultimately pays off.
So does this book actually only take an hour to read? Well, it took me fifty minutes, but people read at different paces. No matter how long it takes, this book won't blaze by you. You'll be reminded of re-occurring themes as you continue the book and the individual stories of each scientist are articulated such that they can easily be referenced later and also are succinct enough to be remembered reasonably well. For students, there's also some neat information in the back of the book that basically translates into a study guide. Overall, it's hard to find a book better than this.
