Machiavelli's "Effectual Truth" Seeds Modern Science and Conspiratorial Politics

Harvey Mansfield, a titan of political philosophy, challenges conventional wisdom on modernity, leadership, and the very nature of knowledge in his conversation with Tyler Cowen. This discussion, centered around Mansfield's book The Rise and Fall of Rational Control, reveals how Machiavelli’s radical idea of "effectual truth" not only seeded modern science but also laid the groundwork for a deeply conspiratorial view of politics. The implications are stark: our modern obsession with empirical fact, while seemingly objective, can obscure deeper truths and lead us astray. This conversation is essential for anyone seeking to understand the hidden currents shaping our political discourse and the enduring power of foundational ideas, offering a critical lens for leaders, strategists, and thinkers who wish to navigate the complexities of the modern world with greater foresight.

The Unseen Engine: Machiavelli's "Effectual Truth" and the Birth of Modern Politics

Harvey Mansfield, speaking from the vantage point of 61 years of teaching at Harvard, argues that Niccolò Machiavelli was not merely a political theorist but the architect of the modern world's intellectual machinery. At the heart of this revolution lies Machiavelli's concept of "effectual truth"--a notion that departed radically from the abstract ideals of Plato and Aristotle. Instead of focusing on intent or ideals, effectual truth, as Mansfield explains, concerns itself with "what comes out of the truth, or what is the effect." This is the seed of modern empiricism, shifting the focus from philosophical speculation to observable outcomes.

This shift, Mansfield contends, is the bedrock of modern science. Galileo, he notes, didn't poll philosophers about the Earth's movement; he sought the "effectual truth." This empirical approach, driven by fact rather than opinion, fundamentally altered how we understand the world and our place within it. However, this powerful engine of knowledge, while enabling technological advancement and national defense--gunpowder being a prime example driving military technology--also carries a hidden cost. The relentless pursuit of what is, rather than what ought to be, can lead to a worldview where politics is inherently conspiratorial.

Machiavelli, in his seminal works, dedicates significant space to the mechanics of conspiracy, detailing its stages and pitfalls. Mansfield observes that this focus on behind-the-scenes machinations, where "what is going on behind the scenes is more important" than public pronouncements, resonates disturbingly with contemporary political discourse, particularly on the right. This conspiratorial lens, he suggests, arises from the very nature of governance, where secrecy is often a prerequisite for action. As Mansfield puts it, "If you've ever been in charge of someone or something, you know that you can't say everything that you know." Even a babysitter, he wryly notes, must simplify for a child. This necessity for equivocation and planning, for executing actions before they are widely understood, inherently creates a space for what appears to be conspiracy.

"So the fact of a thing is what it is without any wish or intent attached to it. So that means you can go from cause to effect, and that, I think, is the fundamental notion behind modern science."

-- Harvey Mansfield

Yet, Mansfield’s American sensibilities rebel against a purely Machiavellian interpretation of modern politics. He points to the 20th century, particularly America's role in defending against major invasions, as evidence that politics can indeed be driven by defense and unintended good, not solely by conspiracy. This tension--between the inherent secrecy of governance and the ideal of open, principled action--is a critical dynamic that leaders must navigate. The immediate impressiveness of power, as demonstrated by a swift capture like that of Maduro, can overshadow principles, leading to a justification of actions based on their success rather than their rectitude.

The Shakespearean Mirror: Ambition, Vulgarity, and the Democratic Soul

Beyond Machiavelli, Mansfield finds profound insights into leadership and the human condition in Shakespeare. He highlights Macbeth as a powerful exploration of ambition, a force often overlooked in contemporary political science. Lady Macbeth’s urging of her husband underscores the potent, sometimes destructive, role of ambition, a force that shapes both individual actions and the very structure of political systems, like America's separation of powers.

When considering contemporary figures, Mansfield places President Trump within Shakespeare's landscape of "vulgarian" characters. Trump, he argues, is not a gentleman and operates through "discordant impulse," seeking to impress rather than persuade. This quality, paradoxically, makes him "more democratic than the rest of us" because he can connect with and influence those whose thinking is less refined. This is the "vulgarity of democracy," a concept Shakespeare explored through characters like those around Falstaff.

"President Trump is in his way more democratic than the rest of us, because he's able to understand and to impress people who are not refined in their thinking and in their ways."

-- Harvey Mansfield

This notion of "vulgarianism" and its connection to the edge of civilization also surfaces when discussing Bronze Age Pervert. Mansfield, having read his dissertation, sees him as deliberately exploring the "dirty necessities of politics and of founding," operating at the periphery of civilization where violence and foundational acts are most apparent. However, he firmly rejects the idea that this makes him a model for Straussianism, emphasizing that such figures operate outside the rigorous, context-aware reading methods championed by Leo Strauss.

The Enduring Power of Great Books: Straussianism and the Art of Reading

Mansfield expresses concern about the future of Straussianism, noting the passing of key figures and the potential for its methods to be misunderstood or misrepresented. He dismisses figures like Bronze Age Pervert as not representative of true Straussianism. Instead, he anchors the enduring relevance of Strauss in the "great books" themselves. These texts, he argues, possess a self-sustaining power that guarantees their continued study. The challenge, then, is not the availability of great texts, but the ability to read them with the depth and nuance that Strauss advocated.

He criticizes the limitations of analytic philosophy, which tends to isolate arguments from their context, as opposed to Strauss's approach of understanding arguments within the "dialogue or the implicit dialogue" of the text. This Straussian method, emphasizing "logographic necessity"--the idea that nothing in a great book is accidental--requires readers to engage with the author's intended audience and purpose. This often involves recognizing irony, where an argument presented might be deliberately inferior, designed for a specific interlocutor, requiring the reader to elevate it to the author's intended level.

"So to understand it, you don't want to go to some second-rate explanation that doesn't take account or departs from the text."

-- Harvey Mansfield

Mansfield also offers a critique of thinkers like John Rawls, suggesting that Rawls's "public reason" misses the vital Straussian insight that reason must always account for the audience, which is typically less reasonable than the author. He advocates for understanding the author's context first, as Machiavelli did with his concept of "ambitious idleness" as the context for Christian Europe. This approach, he believes, allows for a more accurate understanding of empirical propositions, where exaggeration, rather than being an enemy, can be a requirement for empirical analysis that aims to predict and manage outcomes.

The Eclipse of Manliness and the Wisdom of Age

Mansfield touches on a perceived "eclipse" rather than decline of manliness, suggesting that this aspect of human nature, when not expressed constructively, can manifest in destructive ways, such as the political assassinations he notes. He links this to a broader cultural shift, acknowledging the influence of feminism while asserting the enduring need to acknowledge and channel male distinctiveness constructively.

Finally, reflecting on aging, Mansfield draws on Aristotle to describe how the lengthening past and shortening future of old age sharpen concern for the present. While acknowledging that this perspective might become too short-term, he values the reflective wisdom it can bring. This perspective, he suggests, is not necessarily more correct than that of youth, but it offers a different, valuable lens through which to view the world and one's place within it.
