What can Montesquieu still teach us today? Montesquieu was the first political writer who first formulated the principles of separation of powers and the independence of justice. He was the first to scientifically study human institutions, both ancient and modern, Asiatic and European, African and American. Again, he was the first thinker to theorize Federal Democracy, systematically tracking down the root causes of human events in its environmental, cultural, historical, and geographical aspects. Analysing several aspects of Montesquieu’s philosophical and political thought, this volume highlights his stoicism, realism, anti-despotism as well as his staunch defence of human dignity. Introducing one of the sharpest thinkers of modernity, this book offers fundamental tools to understand the very ground of our contemporary times.
