The thirteen essays in this Modern Library edition comprise a complete survey of the golden age of English philosophy. The anthology begins in the early seventeenth century with Francis Bacon's comprehensive program for the total reorganization of all knowledge; it culminates, some two hundred and fifty years later, with John Stuart Mill. The thinkers represented here are the creators of the twentieth-century world. Indebted to them is a long line of economists, sociologists, and political leaders whose work has profoundly influenced the life and thought of our own time.
