It would unbalanced to call out a few gems--they're all here. Readers will find the expected heirlooms from Dobzhansky, Haldane, Einstein and Darwin, plus plenty of surprises from Shakespeare to Twain to Frank Lloyd Wright, as well as the inclusion of writers who haven't quite barged into the canon....Here the dross is minimal, and the riches are high-grade ore." -American Scientist.
