Self-Defense: Judith Jarvis Thomson
I. Introduction to Self-Defense
Initial Reflection:
Self-defense is often seen as morally clear-cut, allowing individuals to protect their lives from threats. However, the morality becomes complex when self-defense involves killing another person.
Argumentative Structure: Thomson begins by acknowledging a common, intuitive understanding of self-defense, then immediately highlights its complexity to set up her deeper inquiry, challenging the simplistic view.
Example Case - Villainous Aggressor:
Scenario involves the audience standing in a meadow when a truck (driven by someone who harbors hatred towards them) heads towards them.
The audience is unable to run away or sidestep.
They possess an anti-tank gun, which could destroy the truck and kill the driver.
Moral Permissibility: It is permissible for the individual to blow up the truck as an act of self-defense, as it is necessary to save their life.
Important Distinction: More than just an excuse for killing the driver, it is a moral permit.
Logical Move: Thomson uses this clear-cut scenario to establish a foundational premise: that killing in self-defense, when faced with a malicious, life-threatening aggressor, is not merely excusable but morally permissible. This sets a baseline for later comparisons where the aggressor's fault is absent. She implicitly assumes that the right to self-preservation in such extreme circumstances takes precedence over the aggressor's life, especially when the aggressor is at fault.
II. The Nature of Moral Permission in Self-Defense
Distinctions in Moral Responsibility:
To merely have an excuse means to act wrongly but be less at fault due to extenuating circumstances.
Moral Permit vs. Excuse: Acting in self-defense is deemed permissible in Villainous Aggressor, cannot be considered merely excusable.
A person is morally permitted to kill in clear cases of self-defense.
Logical Move: Thomson emphasizes the distinction between an excuse (acting wrongly but being not entirely blameworthy) and a moral permit (acting rightly). Her argument is that in self-defense scenarios like 'Villainous Aggressor', the act of killing is not simply forgiven; it is morally justified. This strong claim is crucial for her subsequent arguments, as it moves the discussion beyond merely mitigating blame to establishing a positive right to act.
Consequences of the Aggressor's Nature:
Examination of whether the nature of the aggressor (villainous vs. faultless) affects moral permissibility.
Hypothetical - Innocent Aggressor:
In a variant case where the driver is not at fault due to a drug-induced episode, self-defense remains permissible.
Moral Evaluation: Killing the truck driver in Innocent Aggressor is considered morally acceptable just like in Villainous Aggressor.
The absence of fault does not render the aggressor morally above reproach if they pose a lethal threat.
Logical Move: This is a crucial step in Thomson's argument. She introduces the 'Innocent Aggressor' hypothetical to test the widely held intuition that an aggressor's fault matters morally. By demonstrating that self-defense is still permissible even when the aggressor is not morally at fault, she argues that the moral status of the aggressor, specifically their culpability, is irrelevant to the permissibility of self-defense in life-threatening situations.
Implicit Assumption: She assumes that the right to self-defense is fundamentally about averting a lethal threat to one's life, rather than about punishing or rectifying a wrong done by the aggressor. The aggressor's innocence (lack of fault) does not negate the threat they pose or the victim's right to life.
III. Addressing Opposing Views on Self-Defense
Debate on Moral Worthiness:
Some argue that morally, self-defense is merely excusable in cases involving innocent aggressors.
Thomson counters that the distinction between fault and permission is too simplistic and neglects the complexity of moral obligations.
Logical Move: Thomson directly addresses a common counter-argument: that while one might be excused for killing an innocent aggressor, it's not truly permissible. She refutes this by arguing the underlying moral framework that relies so heavily on fault is overly simplistic. She asserts that a more nuanced understanding of rights and threats is necessary, pushing back against a blame-centric view of morality in these extreme cases.
Implications of Fault in Aggressors:
Fault may not be relevant when self-defense involves life-threatening scenarios, regardless of the aggressor's moral standing.
Argumentative Structure: This re-emphasizes her core contention from the 'Innocent Aggressor' case, solidifying the idea that the lethality of the threat, not the moral status of the threat-poser, is paramount in determining the permissibility of self-defense.
Gradation of Harm:
Fault may become relevant when considering less severe forms of aggression (such as theft)
Example Cases: Killing is not permissible to defend against situations involving loss of property (like a hat). Complexity arises in ambiguous cases of harm.
Greater aggression merits a more significant moral response.
Logical Move: Thomson introduces a crucial qualification. While fault may be irrelevant in life-threatening self-defense, she concedes it can be relevant in less severe cases, or when the harm is not lethal (e.g., defending property). This shows she is not arguing for carte blanche self-defense, but rather drawing a specific line where the stakes are life and death. This move preempts criticisms that her argument would justify excessive force in minor aggressions.
Implicit Assumption: She assumes a proportionality principle: the response in self-defense must be proportionate to the harm threatened.Moral Assumptions in Self-Defense:
The reasoning around innocent aggressors (and whether the aggressor's fault matters) may be flawed if it relies entirely on ethical standards within moral theory.
Argumentative Structure: Thomson critiques the foundational assumptions of opposing views, suggesting that if their reasoning hinges solely on abstract ethical standards without correctly accounting for intuitive moral judgments in specific cases, their framework might be flawed. She implicitly advocates for an approach that is more attuned to the specific moral realities of self-defense scenarios rather than rigid theoretical constructs.
IV. Examination of Different Hypothetical Cases
Hypothetical Case - Innocent Threat:
In this situation, a fat man falls toward you due to another's action. Shifting an awning to deflect the fat man is considered morally permissible.
The moral standing of the fat man does not preclude the need for self-defense against a life-threatening situation.
Logical Move: This 'Innocent Threat' scenario further refines her argument. Here, the threat isn't an aggressor per se but a body in motion. The permissibility of deflecting the fat man (an innocent threat) reinforces her point that the agent's culpability is secondary to the immediate threat to one's life. The 'fat man' is not an 'aggressor' with agency but a threat, blurring the lines further and focusing purely on the right to avert a lethal impact.
The Effect of Agency on Rights Violations:
Addressing the notion of whether rights can be violated without agency—suggesting that mere existence in life-threatening situations can violate rights.
Logical Move: Thomson explores the profound question of whether a person who poses a threat (even an innocent one) can, by their mere presence, be said to be violating another's rights, and if this violation justifies defensive action. She suggests that the concept of a 'rights violation' might not require intentional agency, particularly when one's life is at stake due to another's physical presence or action (intentional or not).
Different Scenarios:
Exploring the nuances between whether a threat is intentional or incidental (natural events or induced by another person).
Argumentative Structure: By differentiating between intentional and incidental threats, Thomson continues to dismantle the idea that moral fault or intention is a necessary condition for justifying self-defense. This reinforces her consistent logical move: the nature of the threat (life-threatening) is more important than the nature (or fault) of the threat-bearer.
V. The Role of By-Stander Cases
Substitution of a Bystander Cases:
Ethical dilemma arises in identifying when it is permissible to take actions that might harm innocent bystanders in order to protect oneself.
Example - Trolley Case:
A trolley is headed for you, and the only way to deflect it onto a track where an innocent bystander stands violates moral rights, creating a clear wrong.
Logical Move: This section introduces a critical distinction. Thomson argues that while it's permissible to harm an innocent aggressor/threat to save oneself, it is not permissible to harm an entirely innocent bystander who poses no threat to save oneself. The 'Trolley Case' here, where diverting a threat from oneself onto an innocent bystander, serves to highlight that there are limits to self-defense. One cannot transfer a threat from oneself to a non-threatening third party.
Use of a Bystander Cases:
Allows for actions using others to protect oneself, raising ethical questions about agency and intention.
Logical Move: Thomson delves into scenarios where an individual might actively use a bystander as a means of self-protection. She generally deems such actions impermissible, reinforcing the idea that bystanders, who are not part of the threatening situation, have a stronger claim to non-harm than innocent aggressors do to non-harm from the threatened individual.
Riding Roughshod Over a Bystander Cases:
Scenarios that do not directly use bystanders as equipment but involve risking them altogether are also impermissible.
Logical Move: This expands the impermissibility to situations where one does not 'use' a bystander but takes actions for self-defense that foreseeably endanger them. This further solidifies the moral boundary: the right to self-defense does not extend to sacrificing or unduly endangering non-threatening third parties.
Implicit Assumption: These cases demonstrate that while one has a strong right to defend against a direct threat, this right is constrained by the rights of non-involved parties not to be harmed or used as a shield by others. There's a distinction between being a source of threat (even innocently) and being an unrelated third party.
VI. Comparative Analysis of Moral Permissibility in Warfare
Doctrine of Double Effect:
Applies to differentiating self-defense within war contexts, such as in Strategic vs. Terror Bomber cases, emphasizing proportional good over anticipated bad consequences stemming from wrongful actions.
Logical Move: Thomson links her analysis of individual self-defense to broader ethical principles, specifically the Doctrine of Double Effect, which is often applied in warfare and medical ethics. This doctrine distinguishes between intended harm (terror bombing, which is wrong) and foreseen but unintended harm (strategic bombing of military targets, which may be permissible even if it causes civilian casualties). This comparison highlights how moral permissibility in life-and-death situations often hinges on intention and the directness of the harm.
Question of Habituation:
The intricacies of these defense scenarios highlight the implications of faulty moral reasoning especially in different life-threatening contexts.
Argumentative Structure: Thomson suggests that our moral intuitions and reasoning can become 'habitual' or rigid, leading to flawed conclusions if not rigorously tested against complex hypotheticals. She underscores the need for careful, nuanced ethical thinking in these areas, warning against relying on simplistic rules that don't capture the full moral landscape.
VII. Conclusion and Philosophical Implications
Reflecting on Moral Intuitions:
Engaging with self-defense necessitates a consideration of not only personal rights and life but understanding of intentions and moral gaps in reasoning regarding fault and permissible actions.
Argumentative Structure: Thomson brings the discussion full circle, emphasizing that a thorough understanding of self-defense requires moving beyond superficial intuitions. It demands a deep dive into the interplay of individual rights, intentions (or lack thereof), and the limitations of conventional moral frameworks that might overemphasize fault or blame.
Final Note on Agency and Bystanders:
The differentiation of moral standing should not be grounded solely on fault, rather depending on the broader context, rights violations, and the nature of the threat posed.
Logical Move & Conclusion: Thomson's ultimate conclusion reinforces her key argument: the permissibility of self-defense, particularly when lethal force is involved, is determined more by the nature of the threat (i.e., whether it directly violates one's right to life) and the context (e.g., aggressor vs. bystander) than by the moral fault or agency of the one posing the threat. She stresses that rights violations can occur and justify defense even without an aggressor's intent, and that the protection of bystanders' rights imposes crucial limits on the scope of self-defense.
