- An objector argues that causality is a fundamental principle of science and reason, and that this skeptical conclusion must be wrong. They propose that we should treat the causal principle not as a description of the world we discover, but as a presupposition we must make in order to investigate the world at all. This response is best understood as a revision of which part of the argument?
Answer: It refines premise (1) by introducing a third category: 'transcendental' claims that are preconditions for experience.
This is a classic Kantian response to Humean skepticism. The original argument forces a choice between a priori and a posteriori knowledge. The objection, following Kant, revises the initial premise (1) by rejecting this dichotomy as exhaustive. It introduces a new category of knowledge—transcendental or synthetic a priori—for principles like causality. These are not learned from experience but are necessary structures the mind imposes to make sense of experience. Thus, causality is not a claim to be proven but a necessary presupposition for knowledge. (B) and (C) are rationalist responses, not the specific transcendental move described. (D) is a fallibilist or probabilistic response, which accepts the basic framework of the argument but weakens the conclusion, whereas the objection challenges the framework itself.
- A philosopher of science objects that 'explanation' in science requires making testable predictions, not just positing an entity (a designer) that could account for anything. The 'explanations' offered by intelligent design are untestable. How should premise (1) of the argument be strengthened to rule out such pseudo-explanations?
Answer: Revise (1) to: A scientific theory is superior if it explains more phenomena and makes novel, falsifiable predictions.
The objection targets the vague notion of 'explanation'. The most effective way to strengthen the criterion for a good scientific theory is to incorporate the principles of falsifiability and predictive power, as stated in (C). This is a core concept from the philosophy of Karl Popper and others. It directly addresses the objection by providing a standard that intelligent design fails to meet, as its claims are generally not structured to be testable or falsifiable. (A) appeals to authority, which is a weak philosophical criterion for theory choice. (B) invokes Occam's Razor (parsimony), which is a relevant scientific virtue, but it doesn't address the core problem of testability raised by the objection. (D) brings in consistency, which is important, but a revolutionary theory might overturn background knowledge, so this is not as fundamental as testability.
- An objector argues that a society also has a primary duty to protect the well-being and established way of life of its own citizens, and that unrestricted immigration could strain social services and erode cultural cohesion, thus violating this duty. How could the utilitarian proponent of the argument best revise it to address this concern?
Answer: Refine the conclusion (4) to state that a just society must implement a controlled immigration policy that maximizes happiness without creating significant social instability.
The correct answer (A) is a classic revision strategy: refining the claim. It acknowledges the force of the objection by qualifying the conclusion. Instead of advocating for completely open borders, it proposes a more nuanced policy that still aims to maximize happiness but takes into account the potential negative consequences raised by the objector. This makes the argument more robust and plausible. (B) does not revise the argument but rather dismisses the objection by attacking the motives of those who might be unhappy, which is an aggressive and often ineffective strategy. (C) abandons the utilitarian framework of the original argument in favor of a rights-based one. (D) attempts to strengthen a premise with a very strong empirical claim that may be false and is certainly contestable, potentially making the argument weaker, not stronger.
- An objector argues that this conclusion is too strong. While 'murder is wrong' may not be a factual statement, it certainly isn't meaningless; it serves to express disapproval and influence behavior. In light of this, how could a proponent of the original argument's verificationist principle revise the conclusion (3) to be more nuanced and defensible?
Answer: Revise (3) to: Therefore, ethical statements lack cognitive meaning (i.e., they are not truth-apt), but they possess emotive or prescriptive meaning.
This argument reflects the logical positivist view. The objection pushes for a more sophisticated account of meaning. The best revision is (B), which represents the shift from early positivism to later non-cognitivist theories like emotivism (A.J. Ayer) or prescriptivism (R.M. Hare). This revision refines the conclusion by distinguishing between types of meaning. It concedes the objector's point that ethical statements have a function (expressing emotion, commanding) while still denying them factual, truth-functional content, thus preserving the spirit of the verificationist principle. (A) is a different view (error theory), not a direct refinement of the meaninglessness claim. (C) rejects the core of verificationism by introducing non-empirical truths. (D) attempts to make ethics empirical, a form of naturalism, which is a different approach and contradicts the spirit of premise (2).
- An objector argues that a state completely devoid of any cultural or aesthetic stance would be impoverished and that promoting a rich cultural life is a legitimate state function. This requires making value judgments. How could the original argument's proponent refine premise (1) to allow for some state support of culture while maintaining a core commitment to neutrality?
Answer: Revise (1) to: The state must be neutral about ultimate religious or moral ends, but it can promote 'primary goods' or capabilities that are useful for a wide variety of life plans.
This question tests your understanding of liberal political theory, particularly how neutrality principles can be refined to address practical objections. When you encounter arguments about state neutrality, look for ways the core principle might be preserved while accommodating legitimate concerns.
The objection highlights a real problem: strict neutrality could leave the state culturally impoverished and unable to fulfill legitimate functions. The key insight is distinguishing between different types of state purposes. Answer D resolves this tension by refining neutrality to apply specifically to "ultimate religious or moral ends" - the deepest philosophical questions about what makes life meaningful. However, it allows the state to promote "primary goods" or capabilities that serve multiple conceptions of the good life. Think of things like literacy, artistic skills, or cultural infrastructure that people with very different values can still use to pursue their own vision of flourishing.
Answer A fails because funding all conceptions equally is impossible and would still violate neutrality by endorsing the principle that all views deserve support. Answer B incorrectly shifts the neutrality requirement away from the state entirely, abandoning the core principle rather than refining it. Answer C makes neutrality contingent on democratic votes, but majority rule doesn't resolve the justice-based concern about neutrality - majorities can still impose their conception of the good on minorities.
Remember this distinction: liberal theorists often differentiate between the state taking positions on ultimate questions of value versus providing neutral resources that citizens can use for their own purposes. This allows robust state action while preserving principled neutrality.
- An art critic objects, insisting that Rothko's works are major achievements of 20th-century art. To defend Rothko's status as an artist, which is the most effective revision to the argument?
Answer: Refine the definition in premise (1) to state that art is a form of representation or expression of emotion.
The most effective revision is (B). The objection challenges the argument's conclusion by providing a strong counterexample. The weakest point in the argument is the narrow definition of art in premise (1). By refining this premise to include expression (the expressive theory of art), the argument can now accommodate abstract works like Rothko's, which are often interpreted as expressing profound emotions. (A) is a weak factual claim that is hard to support and misses the philosophical point. (C) is a very radical and unhelpful revision; it abandons the attempt to define art altogether, rather than improving the existing definition. (D) is a poor revision because it concedes that Rothko's work is art but then makes a contentious value judgment against it, which doesn't resolve the core definitional problem.
- David Hume objects that the analogy between the universe and a human-made machine is weak. The universe is a unique case, and we have no experience of other universes being designed to compare it to. We cannot generalize from parts (machines) to the whole (the universe). How could the proponent of the argument best strengthen it against this specific objection?
Answer: Refine premise (2) by shifting the argument from an analogy to an inference to the best explanation, claiming design is a better explanation for complexity than random chance.
Hume's objection powerfully targets the argument's form as a weak analogy. The best way to revise the argument is to change its logical structure. (D) accomplishes this by reframing it as an 'inference to the best explanation' (IBE). This revised argument no longer relies on a direct comparison between the universe and artifacts. Instead, it posits 'design' and 'chance' as competing hypotheses and argues that design provides a better explanation for the observed complexity. This structure is less vulnerable to Hume's specific critique about weak analogies. (A) strengthens a premise but doesn't fix the underlying logical problem of the analogy. (B) is a common move to weaken the conclusion to avoid other objections, but it doesn't address Hume's core problem with the reasoning. (C) is a very strong move that is difficult to defend; it's not clear how one could make such a deductive argument work.
- An objector claims that our intuition strongly suggests the resulting person is the same as the original, because that's where their consciousness and memories are. This challenges the bodily continuity theory. How could the proponent of the theory revise premise (2) to accommodate this intuition?
Answer: Revise (2) to specify that the relevant part of the body for continuity is the brain, as it is the seat of consciousness.
The brain transplant case is a classic counterexample to a simple 'whole body' continuity theory. The most effective revision for the theory is not to abandon it, but to refine it. Option (B) does this by specifying that the brain is the crucial part of the body for personal identity. This 'brain theory' is still a form of physical/bodily continuity, but it correctly locates identity with the source of psychological life, thus accommodating the objection's intuition. (A) weakens the theory to the point of being uninformative. (C) is arbitrary and would lead to strange conclusions (e.g., someone losing identity after massive cell replacement over years). (D) is not a revision but a complete abandonment of the original theory in favor of its main rival.
- This is a classic Gettier problem, which serves as a powerful objection to the JTB theory of knowledge. In response, how might a philosopher best strengthen premise (1) to rule out such cases of accidental justification?
Answer: Revise (1) to: Knowledge is justified true belief where the justification is not based on any false lemmas (false assumptions).
The correct response is (B), known as the 'no false lemmas' condition. The crucial flaw in Smith's justification is that it relies on a false belief—that Jones will get the job. By adding the condition that the justification cannot proceed through a false step, the definition of knowledge is strengthened to exclude Gettier cases like this one. (A) proposes a reliabilist condition; while this is another major response to Gettier, it doesn't address the specific logical structure of this problem as directly as (B) does. (C) sets the bar for justification far too high, making knowledge almost impossible to attain and leading to radical skepticism. (D) defines knowledge by consensus, which is problematic; experts can be wrong, and this makes knowledge relative to a community.
- A deontologist objects that some actions are intrinsically wrong regardless of their consequences. Lying is a classic example. The argument's conclusion violates a fundamental moral rule. To defend the conclusion, how could the consequentialist best revise premise (1) to account for the force of such moral rules?
Answer: Revise (1) to: The rightness of an action is determined by whether it conforms to a set of rules that, if generally followed, would produce the best consequences (Rule Consequentialism).
When you encounter questions about philosophical debates between ethical theories, focus on how each theory can adapt while maintaining its core commitments. This question tests whether you understand how consequentialism can respond to deontological objections without abandoning its fundamental principle that consequences matter most.
The key insight is that Rule Consequentialism (answer D) offers the most sophisticated defense. Instead of evaluating individual acts by their consequences, it evaluates moral rules by asking: "If everyone followed this rule, would the overall consequences be best?" This allows the consequentialist to say lying is generally wrong because widespread lying would produce terrible consequences, while still maintaining that consequences are what ultimately determine morality. The rule against lying becomes justified on consequentialist grounds, not because lying is intrinsically wrong.
Answer A focuses only on character consequences for the individual agent, which is too narrow and doesn't address the broader moral rules deontologists care about. Answer B essentially abandons pure consequentialism by accepting that some duties are intrinsically binding regardless of consequences—this concedes too much to the deontologist. Answer C shifts focus to intended versus actual consequences, but this doesn't resolve the fundamental disagreement about whether certain actions (like lying) are inherently wrong.
Remember that in ethics questions, look for responses that allow a theory to address objections while preserving its core principles. Rule Consequentialism is consequentialism's most powerful response to deontological challenges because it explains why moral rules matter without abandoning the primacy of consequences.
- The monk Gaunilo famously objected to this ontological argument with a parody: One can conceive of a 'perfect island,' than which no greater island can be conceived. By the same logic, this perfect island must exist in reality, which is absurd. What is the most effective way for a proponent of the ontological argument to revise their claim to counter Gaunilo's objection?
Answer: Refine the scope of premise (1) by arguing that the logic applies only to a being with necessary existence, a property which an island, by its nature, cannot have.
The most powerful response to Gaunilo is to distinguish between contingent beings (like islands) and necessary beings. The revision in (B) does this by refining the argument's scope. The claim is that necessary existence is part of the concept of a maximally great being, but not part of the concept of a maximally great island. An island is by definition a contingent thing, so it cannot have the property of necessary existence. This revision blocks Gaunilo's parody without undermining the original argument's logic for God. (A) is actually Kant's objection to the argument, which would destroy the argument, not revise it in its favor. (C) is a plausible response, but it's considered weaker because it gets into a debate about the coherence of 'perfect island' rather than the logical structure of the argument itself. (D) weakens the conclusion so much that it loses the entire point of the ontological argument, which is to prove necessary existence.
- An objector points out that this argument seems to have no logical stopping point. If one must give until the cost becomes 'morally significant,' that could mean giving until one is nearly as poor as those one is helping. This seems too demanding. How could the argument's proponent best refine premise (4) to make the conclusion less extreme while preserving its moral force?
Answer: Revise (4) to state that the obligation is to donate a modest, fixed percentage of one's income, such as a 10% tithe.
This question tests your understanding of how philosophical arguments can be refined to avoid problematic implications while preserving their core insight. The original argument follows a valid logical structure but leads to an extremely demanding conclusion that critics argue is unrealistic and potentially self-defeating.
Answer choice D correctly identifies the best refinement because it addresses the "no stopping point" problem by establishing a clear, reasonable limit while maintaining the argument's moral force. A fixed percentage like 10% provides a definitive boundary that prevents the obligation from expanding until donors become impoverished themselves. This modification preserves the key insight that affluent people have genuine moral obligations to help others, but makes those obligations manageable and sustainable.
Answer A is wrong because it completely abandons the argument's central claim about moral obligation, reducing it to mere permission. This eliminates rather than refines the argument's moral force. Answer B fails because basing obligations on subjective feelings ("done their part") rather than objective impact undermines the argument's logical foundation and could justify trivial contributions. Answer C is incorrect because it doesn't actually refine premise (4) at all—it simply reasserts the problematic conclusion while acknowledging its extreme nature.
When you encounter questions about refining philosophical arguments, look for solutions that address specific logical problems while preserving the argument's essential moral or logical insight. The best refinements typically involve adding reasonable constraints or qualifications rather than abandoning the core claim entirely.
- Judith Jarvis Thomson famously objects by analogy: Imagine you are kidnapped and surgically connected to a famous violinist who needs your kidneys to survive for nine months. Unplugging him would kill him. It seems permissible to unplug yourself. This suggests that the right to life does not entail the right to use another person's body against their will. How does this objection force a revision of the original argument?
Answer: It forces a refinement of premise (1) to specify that the right to life is the right not to be killed unjustly, which opens the question of what constitutes unjust killing.
Thomson's analogy is designed to show that even if we grant the fetus a full right to life (accepting premise 2), the conclusion doesn't follow. The objection's power comes from distinguishing between killing and letting die, or more precisely, between killing unjustly and withholding support one is not obligated to give. Therefore, the best way to revise the argument in response is to refine premise (1). By changing 'right not to be killed' to 'right not to be killed *unjustly*', the argument must now include a sub-argument about why abortion constitutes an unjust killing, directly engaging Thomson's point. (B) is a common way to argue against the conclusion, but it's not the revision forced by this specific objection, which grants personhood for the sake of argument. (C) and (D) miss the core of Thomson's analogy, which is about the limits of the right to life itself, not about weighing it against other factors.
- Immanuel Kant responded to this Humean skeptical argument. He agreed with premise (2) but wanted to save our knowledge of causality. Which of the following represents Kant's strategy of revising the philosophical framework in which the argument operates?
Answer: He refines premise (1), proposing that knowledge arises from sensory experience structured by innate categories of the mind, such as causality.
Kant's 'Copernican Revolution' in philosophy was to synthesize empiricism and rationalism. He did not reject empiricism outright but revised its foundational premise. (B) accurately captures this synthesis: he argued that the raw data of sensory experience is structured and made intelligible by a priori concepts of the understanding, one of which is causality. This way, causality is not found 'in' experience but is a precondition for having intelligible experience. (A) describes a form of classical rationalism (like Descartes), not Kant's synthesis. (C) is a different response to Hume, associated with philosophers like Thomas Reid, which posits a direct experience of causation. (D) is a skeptical or pragmatic move, whereas Kant's goal was to establish the objective validity of our knowledge of causality.
- An objector argues that this conclusion is absurd, as everyday commerce seems perfectly permissible. The argument must have gone wrong somewhere. To correct the argument's misapplication of the moral principle, which revision is most appropriate?
Answer: Refine the interpretation of premise (2), arguing that as long as the transaction is consensual and respectful, the participants are treating each other as ends in themselves as well.
The key to resolving this apparent paradox lies in the subtlety of the phrase 'merely as a means'. The most accurate revision, (C), clarifies the application of the principle. In a normal, consensual transaction, both parties are respected as autonomous agents who agree to the exchange for their own reasons. Thus, they are not treated merely as means. This revision corrects the flawed reasoning in premise (2) without altering the core principle in (1). (A) incorrectly introduces a consequentialist element (harm) into a deontological principle. (B) strengthens the flawed premise, leading more strongly to the absurd conclusion. (D) revises the conclusion without explaining why the premises fail to support the original conclusion, which is the main task.
- This is a standard skeptical argument. A Moorean response seeks to reject the conclusion by insisting on the certainty of common sense. To do this, the Moorean must revise the argument's structure. Which of the following best represents the Moorean revision?
Answer: Reverse the argument's logic: I do know I am sitting here reading (accepting the negation of (3)), and since (1) is true, I must therefore know I am not a BIV (rejecting (2)).
G.E. Moore's famous response is not to find a flaw in one of the premises directly, but to insist that the argument's conclusion is less certain than its negation. The strategy in (C) is to flip the argument on its head. It takes the form of Modus Tollens. The argument is: If P then Q, Not Q, therefore Not P. The skeptic says P is 'I know I'm sitting' and Q is 'I know I'm not a BIV'. The argument is (P -> Q), ~Q, so ~P. The Moorean response says the argument is valid, but we should run it the other way: (P -> Q), P, so Q. Moore claims 'I know I have a hand' (P) is far more certain than 'I don't know I'm not a BIV' (~Q). This is a revision of the argument's application, insisting one premise is more foundational than another. (B) is another anti-skeptical strategy (relevant alternatives theory), but it's not the distinctly Moorean one. (A) and (D) are other possible philosophical moves but do not capture the specific 'reversal' tactic Moore employed.
- A compatibilist philosopher objects to this argument. They accept that all actions are determined (Premise 1) but want to preserve moral responsibility. To achieve this, which premise must they reinterpret or revise, and what is the most effective revision?
Answer: Revise premise (3) by redefining 'could have done otherwise' to mean that the agent would have done otherwise if they had chosen to, even if that choice itself was determined.
The core of compatibilism is to argue that determinism and free will (and thus moral responsibility) are compatible. The standard compatibilist strategy, represented by (A), is to challenge the incompatibilist's definition of freedom. They attack premise (3) by arguing that 'could have done otherwise' doesn't mean the ability to violate the laws of physics, but something like acting without coercion, in line with one's desires. (B) is a confused revision; it doesn't make sense to say an action is determined but the agent could have done otherwise in the libertarian sense. (C) rejects determinism (Premise 1), which is a libertarian strategy, not a compatibilist one. (D) is a form of consequentialist pragmatism about punishment, not a revision of the argument about whether responsibility actually exists.
- A physicalist wishes to rebut this 'knowledge argument'. They concede that an objective, third-person physical description does not seem to capture subjective experience. Which of the following is the most promising strategy for revising the physicalist position in response to this objection?
Answer: Refine the understanding of premise (1), arguing that qualia are physical facts, but they are accessible only from a first-person point of view.
The most sophisticated physicalist response is to argue that the knowledge argument conflates epistemology (how we know things) with metaphysics (what exists). Response (B) does this by refining the interpretation of premise (1). It maintains that there is only one kind of stuff (physical), but it can be known in two different ways (objectively/subjectively). This 'dual-aspect' theory allows the physicalist to agree that something is 'left out' of the objective description without conceding that what is left out is non-physical. (A) is a promissory note about future science; it doesn't solve the philosophical problem today. (C) is the radical strategy of eliminative materialism, which denies the very phenomenon the argument is about—a much stronger and less common revision. (D) abandons physicalism by positing a non-physical subjective world, conceding the argument rather than revising a defense against it.
