Arguing is not just about winning or losing, but about learning, respecting others, and finding common ground.

In a world increasingly divided by polarization and toxic discourse, Walter Sinnott-Armstrong’s Think Again: How to Reason and Argue emerges as a beacon of hope. Published by Oxford University Press, this insightful book isn’t just a guide to winning debates—it’s a heartfelt plea to rediscover the art of constructive disagreement. As a professor at Duke University with over 35 years of teaching experience, Sinnott-Armstrong draws from his popular MOOC and classroom insights to craft a narrative that’s both academic and deeply personal. His mission? To remind us that arguments are tools for growth, not weapons for destruction. Through a blend of cultural critique and practical advice, Think Again challenges readers to step out of echo chambers and engage with opposing views in a way that fosters understanding and respect. If you’ve ever felt stuck in a rut of endless disagreements, this book offers a roadmap to meaningful dialogue.

Polarization: The Divide That Defines Us

Polarization isn’t just a buzzword—it’s the cultural rut we’re all trapped in. Sinnott-Armstrong defines it as the widening gap between groups who see the world through opposing lenses, often refusing to even acknowledge each other’s perspectives. In the U.S., for instance, the partisan gap on key issues has ballooned over decades. Take the belief that “government regulation of business usually does more harm than good”: in 1994, the gap between Republicans (64%) and Democrats (46%) was 18%; by 2014, it surged to 39% (68% vs. 29%). This isn’t just about politics—it spills into religion, science, and even basic facts like climate change.

Partisan Gap on Key Issues

Highlighted Insight: Polarization turns differences into divisions, creating echo chambers where animosity replaces reason.
This growing divide isn’t just a statistic; it’s personal. People increasingly live in communities and social circles that mirror their views—50% of consistent conservatives and 35% of consistent liberals in 2014 prioritized living where most share their politics. The result? We’re not just far apart; we’re hostile, with 58% of Republicans and 55% of Democrats holding very unfavorable views of the opposing party by 2016. Sinnott-Armstrong’s analysis here is a wake-up call: if we don’t bridge this gap, cooperation on global crises like climate change or inequality becomes impossible.

Toxic Talk: When Words Become Weapons

Why are we so antagonistic? Sinnott-Armstrong points to toxic talk as a key culprit. Instead of listening, we interrupt, caricature, and insult. Civil discourse—where we express opposing views fairly and seek points of agreement—is rare. Consider the Brexit debate: Boris Johnson labeled opponents “mad,” while anti-Brexit voices dismissed supporters as xenophobic or racist. Such incivility, amplified by the anonymity of the internet, doesn’t just hurt feelings—it polarizes further by energizing supporters and alienating opponents.

  1. The Cycle of Incivility

Incivility attracts attention and energizes groups but breeds anger and retaliation.

  1. Caricatures Over Understanding

Exaggerating opponents’ views (e.g., calling liberals “communists” or conservatives “greedy”) prevents real engagement.

  1. Internet Amplification

Anonymous trolling and personal attacks, like those faced by philosopher George Yancy, shut down dialogue.

  1. Global Spread

From the U.S. to Europe, toxic talk undermines cooperation on critical issues.

Highlighted Insight: Incivility fuels antagonism and shuts down dialogue, turning potential allies into enemies.
Sinnott-Armstrong’s take on toxic talk is both a diagnosis and a warning. He cites examples like fake psychiatric diagnoses in book titles (Liberalism is a Mental Disorder) that aim for laughs but cut off conversation. The cost is clear: without civil exchange, we can’t understand each other, let alone solve shared problems. His call to tailor speech for constructive exchange, inspired by Anatol Rapoport’s model of civility, feels like a practical antidote to this poison.

The Sound of Silencing: Choosing Ignorance Over Conflict

If toxic talk is loud, silencing is its quiet counterpart. Many avoid arguments altogether, fearing stress or futility. Pew Research shows that majorities of both Republicans (65%) and Democrats (63%) find political discussions with opponents “stressful and frustrating.” The result? People retreat to news sources and social media algorithms that reinforce their views—by 2008, Democrats watched MSNBC 20% more than Republicans, while Republicans favored Fox News 30% more. Curiosity dies when we stop asking “why” and silence dissent.

Highlighted Insight: Silence may seem like peace, but it hides unresolved tensions, preventing growth and understanding.
Sinnott-Armstrong echoes John Stuart Mill’s On Liberty, arguing that silencing opponents—or ourselves—makes us overconfident and prone to error. Without exposure to diverse views, we can’t correct mistakes or deepen our own understanding. His critique of echo chambers, fueled by selective news consumption and cultural norms against questioning (e.g., avoiding religious debates), is a compelling reminder that true peace isn’t avoidance—it’s engagement.

Power of Arguments: Rebuilding Trust and Connection

Amidst the gloom of polarization and toxic talk, Sinnott-Armstrong offers hope: arguments, when done right, can heal. They’re not about winning but about learning new insights, showing respect by asking for reasons, fostering humility by recognizing our limits, and enabling compromise. He challenges the cynics who see emotion as the sole driver (misquoting Hume’s “reason is the slave of the passions”) by showing how reason and emotion work together—fear can signal danger, anger can reflect justified outrage.

Highlighted Insight: Arguments build bridges, not walls, turning conflict into collaboration.
The benefits are tangible: arguments reduce polarization by encouraging abstract thinking (e.g., identifying with a shared national identity) and humility, making us less likely to demonize opponents. Sinnott-Armstrong shares personal anecdotes, like changing his belief about mammals laying eggs after reading evidence, to illustrate that even entrenched views can shift with reason. His vision of argumentation as a path to clarity, connection, and compromise is inspiring—imagine negotiations on global issues like North Korea sanctions succeeding because both sides listened to each other’s reasons. This chapter isn’t just theory; it’s a blueprint for rebuilding trust in a fractured world.
