Shape's about reason, logic, mathematics & much more...
I love the scope of this book; from explaining the rigor of Abraham Lincoln immersing himself "till I could give any propositions in the six books of Euclid at sight" to applying the inherent reasoning and logic of demonstrating proof to far-flung human undertakings.
Ellenberg is a math professor who can write. His speaking style, while forthright, cannot fully contain his enthusiasm for his subject matter. His narration is conversational and reminds me of the best of the Great Lectures books I've enjoyed.
Rational thought and reasoning can be applied to everything from geometry to maps to politics, artificial intelligence to genealogy and biology. The best arguments are "self-evident," and Ellenberg weaves mathematical, cultural and political history into Shape, elucidating great advances in math and other endeavors, from Ancient Greece to the American Revolution; from the thinking of Abraham Lincoln, to gerrymandering today.
Shape will make you think...without making your head hurt too much in the process. What a treat! I'll be up for a second, and perhaps a third listen. And based on Shape, I'm up for trying Ellenberg's other work as well.
