Question 1Unit 1
Which branch of philosophy is primarily concerned with questions about what exists and what is real?
- Aesthetics
- Metaphysics Correct answer.
- Ethics
- Epistemology
Explanation
Metaphysics investigates the fundamental nature of reality, including existence, identity, causation and what kinds of things there are. The other branches each take up a different central question, so only metaphysics has reality as its primary subject matter.
Question 2Unit 1
A student argues that a statement is meaningful only if it can be verified by sensory experience. Which position is the student expressing?
- Relativism
- Rationalism
- Empiricism Correct answer.
- Scepticism
Explanation
Empiricism holds that sensory experience is the source and test of knowledge, so a claim is meaningful only if experience can confirm it. Rationalism instead grants reason an independent role, while scepticism and relativism concern doubt and standpoint-dependence rather than the verification of meaning.
Question 3Unit 1
In Plato's allegory of the cave, what does the journey out of the cave and into sunlight symbolise?
- The body's release from physical illness
- The rejection of all mathematical reasoning
- The soul's ascent from illusion to genuine knowledge Correct answer.
- The political rise of a citizen to power
Explanation
The allegory depicts prisoners mistaking shadows for reality, and the ascent represents the mind moving from appearances to the intelligible forms, culminating in knowledge of the good. The imagery is epistemic and educational, not medical or narrowly political.
Question 4Unit 1
Descartes' method of doubt leads him to conclude that he cannot doubt that he is thinking. What is the point of this conclusion?
- It demonstrates that reason is inferior to experience
- It proves the senses are always reliable
- It provides an indubitable foundation for knowledge Correct answer.
- It shows that the external world does not exist
Explanation
Descartes seeks a foundation that survives even the most extreme doubt, and the certainty of his own thinking serves as that starting point. From this he attempts to rebuild knowledge, rather than to deny the external world outright.
Question 5Unit 1
Which of the following best states the difference between a valid argument and a sound argument?
- A valid argument persuades its audience; a sound argument is written formally
- A valid argument is deductive; a sound argument is inductive
- A valid argument has true premises; a sound argument has a true conclusion
- A valid argument has a correct form; a sound argument is valid with all true premises Correct answer.
Explanation
Validity concerns form alone: if the premises were true, the conclusion could not be false. Soundness adds the further requirement that the premises actually are true, so every sound argument is valid but not every valid argument is sound.
Question 6Unit 1
All mammals are warm-blooded. All whales are mammals. Therefore all whales are warm-blooded. How is this argument best classified?
- Deductively valid and sound Correct answer.
- Deductively valid but unsound
- Inductively weak and unsound
- Inductively strong but deductively invalid
Explanation
The argument has a valid categorical form, and both premises are in fact true, so the conclusion follows with certainty and the argument is sound. Because the conclusion is guaranteed by the premises, it is deductive rather than inductive.
Question 7Unit 1
Which question is most distinctively ethical rather than metaphysical or epistemological?
- What is the nature of causation?
- What makes a person the same individual over time?
- Under what conditions is it right to break a promise? Correct answer.
- How can we know anything about the past?
Explanation
Ethics concerns norms of right and wrong action, so asking when promise-breaking is permissible is a moral question. The other options concern personal identity, knowledge of the past and causal structure, which belong to metaphysics and epistemology.
Question 8Unit 1
A person claims that an action is morally right because it produces the greatest overall happiness. Which theory does this reflect?
- Divine command theory
- Virtue ethics
- Deontology
- Utilitarianism Correct answer.
Explanation
Utilitarianism assesses actions by their consequences, specifically by whether they maximise overall welfare or happiness. Deontology focuses on duties and rules, virtue ethics on character, and divine command theory on God's will.
Question 9Unit 1
A philosopher argues that we cannot step outside our own conceptual schemes to compare them with reality, so no scheme is privileged. Which challenge does this raise?
- The mind-body problem
- The problem of other minds
- The problem of relativism Correct answer.
- The problem of induction
Explanation
If every judgement is made from within some scheme, then cross-scheme standards of truth become hard to justify, which is the relativist challenge. The other problems concern knowledge of other people's minds, justification of induction and the relation of mind to body.
Question 10Unit 1
What does the principle of charity require when interpreting another person's argument?
- Reconstructing the argument in its strongest reasonable form Correct answer.
- Accepting the conclusion as true without scrutiny
- Ignoring any premises that seem unusual
- Replacing the argument with one you find persuasive
Explanation
The principle of charity directs interpreters to attribute the most coherent and plausible reading to an argument before criticising it. This guards against refuting a weakened version of someone's position rather than the position itself.
Question 11Unit 1
Which of the following is an example of an a priori claim?
- Most swans are white
- Sydney is the capital of Australia
- Water boils at 100 degrees Celsius at sea level
- Every bachelor is unmarried Correct answer.
Explanation
An a priori claim can be known through reason alone without empirical investigation, and the connection between bachelorhood and being unmarried follows from the meanings of the terms. The others require observation or factual checking.
Question 12Unit 1
What is the central claim of dualism in the philosophy of mind?
- The mind and the body are distinct kinds of thing Correct answer.
- Only observable behaviour constitutes the mind
- Mental states do not exist
- Mental states are identical with brain states
Explanation
Dualism holds that mind and body are fundamentally different in kind, whether as separate substances or distinct properties. Identity theory, behaviourism and eliminativism each deny this basic separation in different ways.
Question 13Unit 1
A student says: 'If determinism is true, then no one is responsible for anything. But people are clearly responsible, so determinism is false.' Which response best matches compatibilism?
- The conclusion is true because determinism is well supported by physics
- The first premise is false because responsibility is compatible with being caused to act Correct answer.
- Responsibility is an illusion, so the argument proves too much
- The argument is invalid because it denies the antecedent
Explanation
Compatibilists deny that being causally determined rules out moral responsibility, so they reject the first premise rather than the conclusion. They typically argue that responsibility requires acting from one's own desires without coercion, which determinism need not undermine.
Question 14Unit 1
Which question belongs to epistemology rather than metaphysics?
- Are mental events identical with brain events?
- Do numbers exist independently of human minds?
- What is the difference between knowing and merely believing something true? Correct answer.
- Does every event have a cause?
Explanation
Epistemology studies knowledge, belief and justification, so distinguishing knowledge from true belief is a core epistemological question. The other options concern the existence of abstract objects, the mind-body relation and causal necessity, all metaphysical.
Question 15Unit 1
What role does the 'veil of ignorance' play in Rawls' theory of justice?
- It justifies punishing people who break the social contract
- It ensures principles are chosen without knowledge of one's own social position Correct answer.
- It proves that inequality always benefits the worst off
- It shows that moral truths are relative to culture
Explanation
Rawls asks what principles rational people would choose if they did not know their own talents, wealth or social standing. Removing that information is meant to prevent principles being tailored to personal advantage, yielding fair terms of cooperation.
Question 16Unit 1
Which statement best captures the difference between descriptive and normative claims?
- Descriptive claims are true; normative claims are false
- Descriptive claims describe how things are; normative claims prescribe how things ought to be Correct answer.
- Descriptive claims are scientific; normative claims are religious
- Descriptive claims concern facts; normative claims concern only emotions
Explanation
Descriptive claims state how the world is, while normative claims state how it ought to be, including moral and evaluative standards. The distinction concerns the type of claim made, not whether either kind can be true or false.
Question 17Unit 1
An argument states: 'Most philosophers who have studied the issue accept this view; therefore the view is true.' Which fallacy does this most closely resemble?
- Appeal to authority Correct answer.
- Begging the question
- Ad hominem
- Straw man
Explanation
The argument treats the fact that experts accept a view as sufficient evidence for its truth, which is an appeal to authority. Expert opinion can be relevant evidence, but it does not by itself establish the truth of the claim.
Question 18Unit 1
What is a thought experiment primarily used for in philosophy?
- To record the historical development of an idea
- To collect statistical data about people's opinions
- To test a concept by imagining a carefully specified scenario Correct answer.
- To prove a theory by conducting a physical experiment
Explanation
Thought experiments isolate a concept by describing an imagined case and asking what we would say about it, which can reveal tensions in a theory. They are not empirical studies, physical experiments or historical surveys.
Question 19Unit 1
A philosopher claims that we never directly perceive the external world, only our own ideas. Which position is this?
- Naive realism
- Physicalism
- Idealism
- Indirect realism Correct answer.
Explanation
Indirect realism holds that perception is mediated by mental representations, so we infer external objects rather than perceiving them directly. Naive realism denies this mediation, idealism denies mind-independent objects, and physicalism is a broader metaphysical view.
Question 20Unit 1
What distinguishes a deductive argument from an inductive argument?
- Deductive arguments aim to guarantee the conclusion; inductive arguments aim to make it probable Correct answer.
- Deductive arguments concern science; inductive arguments concern ethics
- Deductive arguments are persuasive; inductive arguments are not
- Deductive arguments always have true premises; inductive arguments never do
Explanation
Deduction aims at a conclusion that must be true if the premises are true, while induction supports a conclusion without guaranteeing it. The difference lies in the strength of support claimed, not in the subject matter or persuasiveness.
Question 21Unit 1
Sartre's claim that 'existence precedes essence' means that for humans:
- Their nature is fixed before birth by a designer
- They have no capacity for free choice
- They first exist and then create their own nature through choices Correct answer.
- Their essence is identical with their physical body
Explanation
Sartre denies that humans have a predetermined purpose or nature; we exist first and define ourselves through free choices and actions. This grounds his account of radical freedom and the responsibility that accompanies it.
Question 22Unit 1
Which criticism is most commonly raised against the claim that a perfectly good, all-powerful God exists alongside evil?
- The problem of evil Correct answer.
- The problem of other minds
- The problem of induction
- The is-ought gap
Explanation
The problem of evil argues that the existence of suffering appears inconsistent with a being who is both all-powerful and perfectly good. The other options concern induction, the derivation of values from facts, and knowledge of other minds.
Question 23Unit 1
A theory is criticised because it cannot be shown to be false by any possible observation. Which principle is being applied?
- The categorical imperative
- The principle of sufficient reason
- Falsifiability Correct answer.
- Occam's razor
Explanation
Falsifiability is the requirement that a genuine empirical claim must specify what observations would count against it. Occam's razor concerns simplicity, the categorical imperative concerns moral duty, and sufficient reason concerns explanation.
Question 24Unit 1
What is the central difference between psychological egoism and ethical egoism?
- Psychological egoism is normative; ethical egoism is descriptive
- Both are descriptive claims about human motivation
- Psychological egoism is a descriptive claim about motivation; ethical egoism is a normative claim about how one ought to act Correct answer.
- Both are normative claims about moral duty
Explanation
Psychological egoism asserts that people in fact always act from self-interest, describing motivation. Ethical egoism prescribes that one ought to pursue one's own interest, making it a normative doctrine about right action.
Question 25Unit 1
In a valid syllogism, what is the role of the middle term?
- It guarantees that the premises are true
- It states the moral of the argument
- It appears in the conclusion as the subject
- It links the two premises and does not appear in the conclusion Correct answer.
Explanation
The middle term connects the subject and predicate terms across the premises, allowing the conclusion to relate them, and it is absent from the conclusion itself. Its role is structural, and it does not guarantee the truth of the premises.
Question 26Unit 1
Which branch of philosophy primarily investigates the nature of reality and existence?
- Ethics
- Epistemology
- Metaphysics Correct answer.
- Aesthetics
Explanation
Metaphysics asks what fundamentally exists, including questions about substance, identity, causation, and possibility. Epistemology instead concerns knowledge and justification, while ethics and aesthetics concern value. Thus the study of reality itself belongs to metaphysics.
Question 27Unit 1
A valid argument is one where:
- The premises are all true
- The conclusion is widely believed
- If the premises are true, the conclusion must be true Correct answer.
- The conclusion is true
Explanation
Validity is a structural property: an argument is valid when it is impossible for all premises to be true while the conclusion is false. Truth of premises and conclusion is a separate matter. An argument can be valid even with false premises, as long as the form guarantees the conclusion.
Question 28Unit 1
Which of the following is a normative claim?
- Most people believe that lying is wrong
- Lying often causes distress
- Lying is wrong Correct answer.
- The word 'lying' has five letters
Explanation
A normative claim prescribes or evaluates how things ought to be, rather than describing how they are. 'Lying is wrong' expresses a moral evaluation. The other options are descriptive claims about beliefs, consequences, or language.
Question 29Unit 1
What is the principle of sufficient reason?
- Every effect is greater than its cause
- Everything that exists has a reason or explanation for its existence Correct answer.
- Every event has a cause
- Every claim must be proven before it is believed
Explanation
The principle of sufficient reason states that nothing is without a reason why it is so rather than otherwise. It is broader than causation because it applies to truths and existences, not only events. It is often invoked in cosmological arguments.
Question 30Unit 1
Which philosopher is most associated with the claim that 'man is condemned to be free'?
- Jean-Paul Sartre Correct answer.
- Immanuel Kant
- Thomas Hobbes
- John Stuart Mill
Explanation
Sartre's existentialism holds that humans have no fixed essence and must create themselves through choices, making freedom inescapable. He describes this as a condemnation because we cannot avoid responsibility. Kant, Mill, and Hobbes are associated with other ethical and political frameworks.
Question 31Unit 1
What is the Euthyphro dilemma?
- Is pleasure the highest good or is virtue the highest good?
- Is the soul immortal or is it mortal?
- Is piety loved by the gods because it is pious, or is it pious because it is loved by the gods? Correct answer.
- Is justice the advantage of the stronger or the good of the community?
Explanation
In Plato's Euthyphro, Socrates asks whether actions are loved by the gods because they are pious, or pious because loved. The dilemma challenges divine command theories of morality by asking whether goodness is independent of God's will or arbitrary. The other options refer to different dialogues and problems.
Question 32Unit 1
What is a counterexample in philosophy?
- A case that confirms a general claim
- An argument with true premises and a false conclusion
- A restatement of an argument in different words
- A case that shows a general claim is false Correct answer.
Explanation
A counterexample is a specific instance that conflicts with a proposed universal claim, thereby refuting it. For example, a single justified false belief challenges 'all knowledge is certain'. Confirming cases support a claim but do not refute it.
Question 33Unit 1
Which of the following best defines a fallacy?
- A valid argument with a true conclusion
- A common pattern of reasoning that is unreliable Correct answer.
- A conclusion that is unpopular
- A false premise
Explanation
A fallacy is a recurring type of reasoning error that tends to produce unreliable conclusions, such as begging the question or equivocation. It is about the form or pattern of inference, not merely the truth of a premise. Popularity and validity are separate matters.
Question 34Unit 1
What does it mean to say that an argument is sound?
- It contains no premises
- It is persuasive to most people
- It is valid and all its premises are true Correct answer.
- It is valid and its conclusion is true
Explanation
Soundness combines validity with true premises. Because a valid argument transmits truth from premises to conclusion, a sound argument guarantees a true conclusion. Validity alone does not ensure truth, and persuasiveness is irrelevant to soundness.
Question 35Unit 1
Which question is most distinctively epistemological?
- What is the nature of time?
- What is the good life?
- What makes a belief justified? Correct answer.
- What is beauty?
Explanation
Epistemology is the study of knowledge, belief, and justification, so asking what makes a belief justified is central to it. The nature of time is metaphysical, the good life is ethical, and beauty is aesthetic. Thus only the second option falls squarely within epistemology.
Question 36Unit 1
A student argues: 'Either the mind is the brain or it is a separate substance. The mind is not the brain. Therefore it is a separate substance.' Which logical form does this argument take?
- Hypothetical syllogism
- Modus ponens
- Modus tollens
- Disjunctive syllogism Correct answer.
Explanation
The argument has the form 'P or Q; not P; therefore Q', which is a disjunctive syllogism. Modus ponens uses a conditional with affirmation of the antecedent, and modus tollens denies the consequent. Hypothetical syllogism chains conditionals.
Question 37Unit 1
Descartes' evil demon thought experiment is designed primarily to:
- Establish that the mind is the brain
- Demonstrate that God exists
- Show that sensory knowledge can be doubted Correct answer.
- Prove that the external world exists
Explanation
Descartes imagines an all-powerful deceiver to push scepticism to its extreme, showing that even sensory and mathematical beliefs could be false. This motivates his search for an indubitable foundation of knowledge. The demon does not prove the external world or God's existence by itself.
Question 38Unit 1
A compatibilist about free will and determinism would most likely claim that:
- Freedom is compatible with determinism when actions flow from one's own desires without external constraint Correct answer.
- Moral responsibility is an illusion
- Determinism is false because we experience freedom
- Freedom requires the ability to do otherwise in an absolute sense
Explanation
Compatibilists redefine freedom as acting according to one's own will without coercion, which can coexist with causal determinism. They deny that freedom requires contra-causal power. Thus they reject both libertarian freedom and the claim that responsibility is impossible.
Question 39Unit 1
What is the difference between act utilitarianism and rule utilitarianism?
- Act utilitarianism applies only to public actions, while rule utilitarianism applies only to private actions
- Act utilitarianism is concerned with intentions, while rule utilitarianism is concerned with outcomes
- Act utilitarianism assesses individual actions by their consequences, while rule utilitarianism assesses rules by their consequences Correct answer.
- Act utilitarianism is a form of deontology, while rule utilitarianism is a form of virtue ethics
Explanation
Act utilitarianism asks whether a particular action maximises overall happiness, whereas rule utilitarianism asks whether following a general rule would maximise happiness. Both are consequentialist, so they share a focus on outcomes. The distinction lies in the object of evaluation: act versus rule.
Question 40Unit 1
A person says: 'I know that Sydney is the capital of Australia, but I am only guessing.' What does this show about the standard analysis of knowledge?
- Knowledge requires justification in addition to true belief Correct answer.
- Knowledge does not require belief
- Knowledge requires truth but not justification
- Knowledge is impossible
Explanation
The standard analysis holds that knowledge is justified true belief. A true belief held merely by guesswork lacks justification, so it is not knowledge. The example illustrates why justification is a necessary condition alongside truth and belief.
Question 41Unit 1
Which criticism is most commonly directed at Descartes' ontological argument for God's existence?
- It contradicts the cosmological argument
- It proves too little because it only shows God is possible
- It assumes that existence is a property that can be included in a concept Correct answer.
- It relies on empirical evidence that is unavailable
Explanation
Kant's objection is that existence is not a real predicate that adds to the concept of a thing; a hundred real dollars do not contain more concept than a hundred possible ones. The ontological argument treats existence as a perfection that can be part of God's essence. Hence the standard criticism targets the assumption that existence is a property.
Question 42Unit 1
According to Aristotle, what is the highest human good, and how is it achieved?
- Eudaimonia, achieved through virtuous activity over a complete life Correct answer.
- Honour, achieved through public recognition
- Pleasure, achieved through sensory indulgence
- Wealth, achieved through accumulation of resources
Explanation
Aristotle identifies eudaimonia, often translated as flourishing or happiness, as the highest good. It is achieved through the exercise of virtue, especially rational activity, across a whole life. Pleasure, honour, and wealth are incomplete goods that are sought for the sake of something else.
Question 43Unit 1
What is the difference between a priori and a posteriori knowledge?
- A priori knowledge is independent of experience, while a posteriori knowledge depends on experience Correct answer.
- A priori knowledge concerns universals, while a posteriori knowledge concerns particulars
- A priori knowledge depends on experience, while a posteriori knowledge is independent of experience
- A priori knowledge is certain, while a posteriori knowledge is uncertain
Explanation
The distinction concerns how knowledge is justified: a priori justification does not rely on sensory experience, as in mathematics, while a posteriori justification does, as in empirical observation. Certainty and universality are separate issues that do not define the distinction. Thus the second option correctly states the contrast.
Question 44Unit 1
Which statement best captures the difference between deontological and consequentialist ethics?
- Deontology focuses on the rightness of actions themselves, while consequentialism focuses on outcomes Correct answer.
- Deontology is religious, while consequentialism is secular
- Deontology is about character, while consequentialism is about rules
- Deontology applies only to individuals, while consequentialism applies only to governments
Explanation
Deontological theories hold that certain actions are right or wrong in themselves, regardless of consequences, whereas consequentialist theories evaluate actions by their outcomes. The other options misdescribe the distinction. Character ethics is a third category, virtue ethics, not deontology.
Question 45Unit 1
A philosopher claims that mental states are identical to brain states. Which position is this?
- Behaviourism
- Identity theory Correct answer.
- Substance dualism
- Property dualism
Explanation
The identity theory of mind holds that mental states are numerically identical with physical brain states. Substance dualism treats mind and body as distinct substances, and property dualism treats mental properties as non-physical. Behaviourism analyses mental talk in terms of observable behaviour.
Question 46Unit 1
What does the principle of double effect permit?
- Ignoring all consequences of an action
- Following rules only when they are convenient
- Doing evil so that good may come of it
- Performing an action with a good intended effect and a foreseen harmful side effect, under certain conditions Correct answer.
Explanation
The principle of double effect allows an action with a good intended outcome even if it has a foreseen bad side effect, provided the bad effect is not intended as a means and is proportionate. It is used in just war and medical ethics. It does not license doing evil for good ends.
Question 47Unit 1
Which of the following is an example of the naturalistic fallacy as identified by G.E. Moore?
- Arguing from a sample to a population
- Defining 'good' in terms of a natural property such as pleasure Correct answer.
- Assuming that what is natural is statistically common
- Deriving an 'ought' from an 'is'
Explanation
Moore argued that 'good' is a simple, indefinable property, and that identifying it with any natural property like pleasure commits the naturalistic fallacy. His open-question argument aims to show that such definitions fail. The is-ought gap is a related but distinct issue associated with Hume.
Question 48Unit 1
What does Rawls' original position require participants to do?
- Maximise total utility regardless of distribution
- Preserve traditional social hierarchies
- Choose principles of justice behind a veil of ignorance about their own social position Correct answer.
- Decide each case by appealing to natural law
Explanation
Rawls asks parties in the original position to select principles of justice without knowing their talents, wealth, or conception of the good, behind a veil of ignorance. This ensures impartiality and leads to his two principles of justice. It is not a utilitarian or traditionalist device.
Question 49Unit 1
Consider the claim: 'Every event has a cause. Therefore, the universe itself must have a cause.' Which criticism is most relevant?
- It is a valid deductive argument with no issues
- It commits the fallacy of composition by assuming what is true of parts is true of the whole Correct answer.
- It relies on a false premise about the universe
- It confuses necessary with sufficient conditions
Explanation
The argument moves from a principle about events within the universe to a conclusion about the universe as a whole, which is a compositional inference. Such inferences are not automatically valid, since wholes can have properties their parts lack. Hence the most relevant criticism is the fallacy of composition.
Question 50Unit 1
A neuroscientist claims that because a brain state is correlated with a conscious experience, the experience just is the brain state. Which objection is most pressing?
- Brain states are not physical
- Correlation does not entail identity, since two things can be correlated without being the same Correct answer.
- Neuroscience cannot measure anything
- Conscious experiences are private and cannot be studied
Explanation
The inference from correlation to identity is too quick: lightning is correlated with thunder but is not thunder. Similarly, mental states may correlate with brain states without being identical. The other objections misstate the scientific or metaphysical situation.
