In How to Think: The Liberal Arts and Their Enduring Value, Professor Michael D. C. Drout gives an impassioned defense and celebration of the value of the liberal arts. Charting the evolution of the liberal arts from their roots in the educational system of Ancient Rome through the Middle Ages and to the present day, Drout shows how the liberal arts have consistently been "the tools to rule", essential to the education of the leaders of society. Offering a reasoned defense of their continuing value, Drout also provides suggestions for improving the state of the liberal arts in contemporary society.
