Essays, or discourses, vol. 4 (of 4) — Background and Themes

Redefining Paradox and Challenging Common Sense

Feijoo begins by distinguishing his use of "paradox" from mere falsehood, insisting that the term describes propositions that are initially incredible but can be shown true or probable through careful reasoning. He immediately applies this method to elemental fire, arguing that it is not hot in the highest degree—a claim that contradicts the "vulgar physics" of his time. His evidence is concrete: the heat of the sun concentrated through a burning glass surpasses any effect of elemental fire. This opening move establishes a pattern of argument that recurs throughout the volume: identify a widely held belief, subject it to logical and empirical scrutiny, and propose a counterintuitive alternative.

The Rhetoric of Moral and Political Paradox

In the section on moral and political paradoxes, Feijoo turns his skeptical lens on acts commonly praised as magnanimous. He recounts an anecdote of a king who, upon hearing a subject wish for a sum of money, immediately gives it to him. Where others see generosity, Feijoo sees weakness and a want of reflection—a rash impulse driven by vanity rather than true virtue. He then poses a pointed question: if making one man happy is glorious, is it not far more glorious to make a whole nation so? This rhetorical strategy, moving from a specific example to a general principle, characterizes his method throughout the political essays.

The Ocean and the Treasury: A Sustained Analogy

Feijoo develops one of his most striking analogies when discussing royal finance: the treasury is like the ocean, receiving contributions from all the kingdom as the ocean receives waters from every stream. Just as the ocean must return that water in refreshing rains to fertilize the earth, so must the treasury redistribute wealth to benefit the whole nation, not merely a few individuals. The analogy is extended with precision—if the ocean only watered a few districts, the rest would become barren; similarly, if a prince hoards or squanders public money on favorites, the majority of subjects suffer. This image recurs as a touchstone for Feijoo's economic arguments.

Evidence from Missionary Reports and Historical Example

Feijoo supports his political arguments with specific sources, notably the letters of Father Contanein describing the emperor of China at the beginning of the eighteenth century. He cites the eighteenth volume of Edifying and Curious Letters of Foreign Missionaries and an extract in the Memoirs of Trevoux of 1728. This reliance on contemporary travel and missionary accounts is characteristic of Feijoo's method: he draws on a wide range of authorities, from classical philosophy to recent Jesuit reports, to ground his paradoxes in observable reality. The Chinese emperor is presented as a model of a ruler who labored incessantly to promote the good of his subjects—a contrast to the vain king of the earlier anecdote.

Readers approaching this volume should attend to Feijoo's habit of questioning not just received opinions but the very terms in which they are expressed. His paradoxes are not mere provocations; they are invitations to examine evidence and reasoning. The translator's preface and notes, if present, may clarify eighteenth-century references, but the essays themselves reward careful reading of their analogies and rhetorical structures.

There’s something about Feijoo’s paradoxes that stays with you—not as answers, but as quiet questions. I felt that same lingering weight reading The Works of Samuel Johnson, in Sixteen Volumes. Volume 04 — Reading Notes. His moral observations sit beside you like an old friend’s hand on your shoulder, unhurried, patient, and oddly comforting in their honesty.
