Political Principles of Sovereigns

While there are no specific comments from other philosophers or intellectuals on this work, its weight lies in Diderot's unwavering commitment to the ideals of justice, equality, and the common good. Written at the cusp of the American revolution and in sight of Rousseau's more famous works, Political Principles of Sovereigns (Principes politiques des souverains, 1774) is a concise political treatise articulating Enlightenment ideals of governance, justice, and the moral responsibilities of rulers. Drawing from Enlightenment thought, the treatise promotes a vision of enlightened absolutism, where monarchs should use their power rationally and benevolently, guided by philosophical and moral understanding rather than tradition or superstition. Written as a clandestine rebuttal to Catherine the Great's absolutist pretensions, the text argues that a ruler's legitimacy hinges on their service to collective welfare, justice, education, economic equity, not ceremonial pageantry or brute force.

Diderot grafts Enlightenment materialism onto governance: laws should be mutable organisms adapting to social needs, not holy writ. He strips sovereignty of mystique, likening kings to head gardeners entrusted with pruning a nation's growth, their authority withering if they confuse cultivation with domination. The essay smuggles radical ideas into pragmatic prose, advocating for press freedom, judicial transparency, and the right to revolt, a blueprint for revolution disguised as administrative advice.
