This article reviews two masterpieces of intellectual history: From Dawn to Decadence: 500 Years of Western Cultural Life (by Jacques Barzun) and The Modern Mind: An Intellectual History of the 20th Century (by Peter Watson)
Reading intellectual history is like looking out at the window when the plane takes off. The colossal buildings become smaller and smaller until they are no more than little blocks of lego. It is then you realize how those distinct and individual blocks are connected through streets and roads, so that a coherent image of cityscape begins to emerge. Intellectual history is such a bird’s eye view of the whole intellectual landscape.
