ABSTRACT
This chapter explains that Keynes enjoys two broad categories of readers: policy makers and academics. Academics favor Keynes's work for its 'density', that is, the fact that his work lends itself to many different readings, interpretations, and theoretical extensions. And in academics the most radical Keynesian projects are found, in the political and theoretical senses. The most far-reaching interpretations focus on Keynes's concept of uncertainty and undermine more traditional 'hydraulic' interpretations of his work. The hydraulic interpretations of Keynes offer the most direct fiscal and monetary policy options. Keynes's pragmatism is also daring. Keynes's General Theory was, then, a tool for coordinating beliefs in the interest of making beneficial policies and intended to be a rallying point for those who sought to combat unemployment and spur economic growth. Academic and pragmatic Keynesian approaches to macroeconomics both require creativity and commitment. Keynes's insights offer solutions to the crises of own time.
