The books gathered here range from classical works such as Ibn Khaldun's The Muqaddimah and Thucydides' account of the Peloponnesian War to modern studies of strategy, information networks, manipulation and the forces that shape nations. With these ideas, readers can spot flawed reasoning, make sounder decisions at work and at home, and read events around them with greater clarity and independence.
