Executive Overview
In the landscape of moral philosophy, few concepts capture the public imagination—or intensely divide academic ethicists—quite like the thought experiment. For decades, hypothetical scenarios involving runaway vehicles, impending doom, and agonizing split-second choices have served as the crucible for testing human moral intuitions. Now, the prominent philosophy blog PEA Soup has launched a brand-new, interactive series dedicated entirely to philosophical puzzles and thought experiments, inviting both seasoned academics and curious laypeople to stress-test their ethical frameworks.
The series, titled "PEA Soup Puzzles," is designed as an open forum for the informal yet rigorous exploration of complex dilemmas in moral and political philosophy. According to the blog’s organizers, the overarching goal is to create a dynamic testing ground where philosophers can "try out ideas" and debate thorny questions without the immediate constraints of formal academic publishing. More importantly, the organizers have flung the doors wide open, encouraging the global philosophy community to submit their own custom puzzles for public dissection.
Kicking off this ambitious intellectual endeavor is a provocative inaugural entry by University of Warwick law and philosophy scholar Victor Tadros. Tadros zeroes in on a foundational tension in deontological and consequentialist ethics: the prohibition against using other human beings as mere means to an end, juxtaposed against our intuitive resistance to sacrificing our own well-being for the "greater good."

By introducing a nuanced twist on the classic trolley problem—dubbed "Jump Behind"—Tadros challenges readers to reevaluate the boundary lines between permissible self-defense and the impermissible instrumentalization of innocent bystanders. As PEA Soup rolls out this series, the philosophical community is once again thrust into the weeds of moral theory, where pulling a lever or jumping out of the way can mean the difference between philosophical consistency and moral hypocrisy.
Detailed Chronology: The Evolution of "PEA Soup Puzzles"
To understand the significance of the new series, one must examine the trajectory of PEA Soup as a cornerstone of digital philosophy. Founded as a collaborative blog and community hub for moral, political, and legal philosophy, PEA Soup has long served as a bridge between formal academic discourse and accessible online debate. The inception of the "Puzzles" series did not happen overnight; rather, it is the culmination of months of behind-the-scenes planning by the site’s proprietors.
The Buildup and Announcement
The conceptual groundwork for the series was laid in late September, when the blog’s editorial team published a cryptic "Coming Soon" teaser alerting readers to an upcoming deep dive into philosophical puzzles. The announcement promised a departure from standard peer-reviewed commentary, favoring instead an agile, conversational format centered on raw intuition and conceptual troubleshooting.
"All are welcome to join us in this discussion," the proprietors wrote in their introductory announcement. "Pero beyond that, we would like to invite people to propose their own puzzles for discussion." This crowdsourced element is expected to be a major drawing card for the series, democratizing the generation of philosophical thought experiments and giving early-career researchers and independent thinkers a platform to pitch original dilemmas.
The Launch: Victor Tadros Steps Up
The official rollout commenced with Victor Tadros taking the inaugural slot. Tadros, a distinguished scholar known for his extensive work on criminal law, punishment, and the ethics of self-defense, presented a carefully constructed triad of scenarios designed to interrogate how we think about self-preservation versus the instrumental use of others.
The centerpiece of Tadros’s post—and the focus of immediate online commentary—revolves around a clever modification of traditional track-diversion scenarios. By forcing participants to weigh the mechanics of how a life is saved, Tadros’s puzzles expose deep fissures in common-sense morality. The discussion quickly migrated from the introductory framing pages to the main comment threads on the PEA Soup platform, drawing responses from notable ethicists and graduate students alike.
Supporting Context & Metrics: The Anatomy of Moral Puzzles
To appreciate the weight of Tadros’s contribution to the PEA Soup series, one must contextualize the mechanics of philosophical thought experiments within contemporary moral philosophy.
The Terrain of Deontology vs. Consequentialism
In normative ethics, dilemmas generally fall along a spectrum between consequentialism (which judges actions solely by their outcomes, typically maximizing overall well-being) and deontology (which asserts that certain actions are inherently right or wrong, regardless of their consequences, often encapsulated in Kant’s injunction never to treat people merely as means to an end).
Classic thought experiments—most notably Philippa Foot’s original formulation of the trolley problem in 1967, later expanded by Judith Jarvis Thomson—are designed to test the limits of these theories.
- The Standard Bystander Case: A runaway trolley is hurtling toward five workers. You can pull a lever to divert it onto a side track, killing one worker instead of five. Most people (and most moral theories) find this permissible.
- The Loop Variant / The Fat Man: You can stop the trolley by pushing a heavy man off a footbridge. Even though one life is traded for five, most people deem this impermissible because it involves using the man’s body as a physical barrier.
Victor Tadros’s Triad: Dissecting Jump, Pull, and Jump Behind
Tadros’s contribution to the PEA Soup Puzzles series targets a specific, highly defended intuition: the idea that it is permissible to protect oneself from being sacrificed for the greater good, but impermissible to actively use someone else to achieve that protection.
To test this, Tadros asks readers to consider three distinct scenarios:
-
Jump:
A trolley is heading towards Archie. If it hits him, he will be killed. If he jumps out of the way, it will head on down the track and run over Bella. Those are his only sensible options.
Analysis: Although Archie acts, and his action results in Bella’s death, moral consensus overwhelmingly deems Archie’s action permissible. He is merely exercising a right to self-defense by removing himself from the path of lethal, unprovoked harm.
-
Pull:
A trolley is heading towards Archie. If it hits him, he will be killed. Bella is on the side of the tracks, and Archie can save his life only by pulling Bella in front of him.
Analysis: Here, Archie uses Bella as an instrument to absorb the impact. This is widely viewed as clearly wrong. Archie violates Bella’s bodily autonomy by instrumentalizing her to save his own skin.
-
Jump Behind:
As Jump, except that Archie is only able to jump behind Bella. Doing this will save his life only because the trolley will hit Bella. Had she not been there he would have been unable to save himself.
Analysis: This is where Tadros sets the trap. In Jump Behind, Archie is essentially jumping out of the way (as in the first case), but his survival is causally dependent on the fact that Bella is now in the trolley’s path. If Bella were not standing there, Archie could not save himself via this maneuver. Does this make Bella a "tool" used by Archie, rendering the act morally equivalent to Pull? Or is it merely an instance of self-preservation where a bystander happens to be caught in the collateral fallout?
Quantitative and Qualitative Impact
While formal metrics for blog-based philosophical series are traditionally measured in engagement—such as comment volume, cross-blog citations, and syllabus integration—PEA Soup historically commands a high-impact readership among professional philosophers. Previous discussion series hosted on the platform have frequently sparked peer-reviewed response papers, workshop themes at major American Philosophical Association (APA) divisions, and foundational reading material for graduate-level seminars in moral philosophy.
Official Statements & Academic Perspectives
The philosophy blogging community and the academic wing surrounding PEA Soup have greeted the new series with palpable enthusiasm. Although formal statements from institutional bodies are rare for online blog series, the academic discourse generated by participants provides a clear window into the professional reception of the project.
In his initial framing of the puzzle series, Victor Tadros emphasized the necessity of returning to foundational cases to test the structural integrity of modern legal and moral frameworks. While Tadros’s written work—such as his seminal book The Ends of Harm: The Moral Foundations of Criminal Law—often deals with the weighty architecture of state punishment and defensive force, his contribution to PEA Soup demonstrates a commitment to making these high-level abstractions accessible and digestible for sharp, informal debate.
Commentators on the PEA Soup platform have already begun dissecting the fine lines of Jump Behind. Several graduate students and early-career researchers have pointed out that Jump Behind forces ethicists to choose between two unpalatable interpretations:
- The Causal Dependence View: If your self-preservation causally relies on another person absorbing the blow in a way that you exploit (even passively), your act crosses the line from self-defense to prohibited exploitation.
- The Intentionality/Agency View: As long as Archie’s primary intention is simply exiting the danger zone (rather than positioning Bella as a shield), the moral quality of the act remains aligned with Jump rather than Pull.
The editors of PEA Soup have reiterated their open-door policy, noting that subsequent entries in the series will tackle entirely different domains of philosophy, ranging from distributive justice and political legitimacy to bioethics and epistemology.
Future Outlook: Where Do We Go From Here?
As "PEA Soup Puzzles" gains momentum, its long-term impact on the philosophical ecosystem is expected to be multifaceted. By lowering the barrier to entry for proposing and debating complex moral dilemmas, the series fills a unique niche that bridges the gap between the sluggish pace of traditional academic publishing and the hyper-fast, often superficial nature of mainstream social media commentary.
What Lies Ahead for the Series?
- Diverse Philosophical Domains: While the launch focuses heavily on normative ethics and the metaphysics of action (via Tadros), upcoming posts are slated to explore puzzles from distinct subfields, ensuring broad appeal across the philosophical spectrum.
- Crowdsourced Submissions: With the call for external puzzle proposals now active, the editorial board anticipates a surge of submissions from graduate programs and independent researchers globally. This democratized curation model could elevate previously overlooked theoretical frameworks or novel hybrid dilemmas.
- Classroom Integration: Given the innate pedagogical utility of thought experiments, professors of philosophy and law are expected to incorporate PEA Soup puzzle entries into their syllabi. The bite-sized, highly controversial nature of scenarios like Jump Behind makes them ideal catalysts for undergraduate seminar debates.
Conclusion
The eternal appeal of the trolley problem lies in its frustrating resistance to easy answers. Just when philosophers believe they have mapped the boundary between permissible self-defense and impermissible instrumentalization, thinkers like Victor Tadros construct a hybrid scenario—such as Jump Behind—that forces everyone back to the drawing board.
With the launch of PEA Soup Puzzles, the philosophical community has secured a vibrant, collaborative sandbox to test the limits of human reason. As readers continue to debate the finer points of Archie’s fateful leap in the comment sections, one thing remains certain: the tracks may be hypothetical, but the intellectual friction they generate is entirely real.
