    A runaway trolley will kill five people unless you divert it to another track, where it will kill one person. No other action is possible. Someone argues, “Diverting it is justified because fewer people will die.” What does this argument give priority to?

    • The overall consequences of the available actions.
    • Whether everyone affected has consented to the action.
    • The duty never to intervene in an existing sequence of events.
    • Whether the person acting intends someone's death as a goal.

    Figyeld meg, mit számol össze a beszélő a két kimenetel összehasonlításakor.

    Show solution
    • The overall consequences of the available actions.

    A következményeken alapuló érvelés arra összpontosít, hogy mihez vezet egy cselekedet. Más etikai megközelítések a kötelességeket, a szándékokat vagy a beleegyezést is figyelembe veszik.

    Schrödinger imagines a cat sealed in a box with a device that releases poison if a radioactive atom decays. The atom is described as being in a superposition of decayed and undecayed states, and the device links those states to a dead and a living cat. What puzzle does this highlight?

    • Whether radioactive decay requires a conscious observer to begin.
    • Whether observation, rather than poison, physically causes the cat's death.
    • How a quantum superposition relates to the single definite outcome we observe.
    • Whether an initially hidden state must remain unknowable even after the box is opened.

    The setup connects an atomic state to an everyday object.

    Show solution
    • How a quantum superposition relates to the single definite outcome we observe.

    Schrödinger used the cat to expose the difficulty of extending quantum superposition to everyday objects. Ordinary uncertainty about a hidden animal is not, by itself, a quantum superposition.

    The Ship of Theseus has every plank replaced gradually while remaining in continuous use. Someone then assembles all the removed original planks into another ship. Why does this reconstruction make the identity puzzle sharper?

    • It settles the issue by proving that original material must determine identity.
    • It creates two candidates for the original ship, supported by different criteria of identity.
    • It removes the distinction between continuity through use and continuity of material.
    • It establishes that outward appearance alone determines which ship is original.

    Az egyik hajó története megszakítás nélkül folytatódott; a másik a korábbi anyagát tartalmazza.

    Show solution
    • It creates two candidates for the original ship, supported by different criteria of identity.

    A feladvány elkülöníti az időbeli folytonosságot az anyagi folytonosságtól. Ezek a szempontok különböző tárgyakra mutathatnak anélkül, hogy bármelyik tárgy története vitatott lenne.

    Galileo challenges the claim that heavier objects must fall faster. Assume a lighter, slower object would slow a heavier, faster object if they were tied together. Yet the joined pair would weigh more than the heavy object alone. What conflicting predictions follow?

    • The pair should fall at the same speed as each object falls on its own.
    • The lighter object should speed up while leaving the heavier object's speed unchanged.
    • The heavier object should fall at an unchanged speed regardless of the attached weight.
    • The pair should fall both more slowly and more quickly than the heavy object alone.

    Apply both assumptions to the same joined pair.

    Show solution
    • The pair should fall both more slowly and more quickly than the heavy object alone.

    This is a reductio argument: an assumption is challenged by showing that it produces incompatible conclusions. The imagined setup tests a claim without requiring an actual drop.

    Nozick imagines an experience machine that gives you convincing experiences of achievement, friendship, and happiness. While connected, you would believe those experiences were real, although the events would not actually occur. Someone refuses: “I want to accomplish things, not merely experience having accomplished them.” Which distinction motivates the refusal?

    • Actually achieving something versus having a convincing experience of achievement.
    • Pleasant experiences versus unpleasant experiences.
    • Convincing experiences versus experiences recognized as artificial.
    • Remembered achievements versus achievements that have been forgotten.

    Az ellenvetés arra vonatkozik, ami az illető tapasztalatain túl történik.

    Show solution
    • Actually achieving something versus having a convincing experience of achievement.

    A gép elválasztja a kielégítő belső életet a valósággal való kapcsolattól. Ha az illető emiatt utasítja el a gépet, az arra utal, hogy számára nem a kellemes élmény az egyetlen érték.

    Behind Rawls's “veil of ignorance,” you design society's rules without knowing your future wealth, abilities, or social position. Once the rules are fixed, you will live under them, but you could occupy any position. What bias is this restriction intended to reduce?

    • The tendency to consider how rules might affect disadvantaged people.
    • The tendency to recognize that rules can affect different groups differently.
    • The tendency to tailor rules to a position you know you will occupy.
    • The tendency to remain uncertain about every consequence of a proposed rule.

    Gondold végig, milyen személyes információk adhatnának okot arra, hogy az egyik csoportot előnyben részesítsd.

    Show solution
    • The tendency to tailor rules to a position you know you will occupy.

    A fátyol kizárja azokat az információkat, amelyek elősegíthetnék az önérdekű alkudozást. Nem szünteti meg annak szükségességét, hogy figyelembe vegyük az emberek eltérő körülményeit.

    In Searle's Chinese Room, a person who understands no Chinese follows detailed rules for manipulating Chinese symbols. The resulting written replies convince outside readers that they are communicating with a fluent speaker. Searle uses this case to challenge which inference?

    • A person can follow symbol-handling rules without knowing what the symbols mean.
    • Producing appropriate responses is sufficient, by itself, to establish understanding.
    • A written exchange can appear fluent without involving spoken language.
    • A rulebook can specify responses to particular patterns of symbols.

    Különítsd el a sikeres végrehajtást a végrehajtás jelentésének megértésétől.

    Show solution
    • Producing appropriate responses is sufficient, by itself, to establish understanding.

    Az érvelés különbséget tesz a szimbólumok manipulálása és megértése között. Továbbra is vitatott, hogy a szoba egésze képes lehet-e megértésre; a gondolatkísérlet önmagában nem dönti el ezt a vitát.

    Mary knows every physical fact about human color vision but has spent her entire life in a black-and-white environment. On leaving, she sees red for the first time. Suppose she learns something new at that moment. Which claim is put under pressure by that assumption?

    • Complete physical knowledge already includes every kind of knowledge about color experience.
    • People can learn physical facts about colors without directly seeing those colors.
    • Human color perception involves physical processes in the eyes and brain.
    • Encountering a color directly can differ from reading a description of it.

    Mary's scientific knowledge is complete before she leaves that environment.

    Show solution
    • Complete physical knowledge already includes every kind of knowledge about color experience.

    The debate concerns what, if anything, first-hand experience adds. Some philosophers interpret Mary's gain as new factual knowledge; others describe it as a new ability or acquaintance.

    On Earth, “water” refers to H₂O. On a fictional Twin Earth, an outwardly indistinguishable liquid has a different chemical structure. Two speakers have identical internal mental states, but each learned the word “water” through contact with the local liquid. Putnam's account allows their words to refer to different substances. What follows about reference on this account?

    • It depends on the speaker consciously knowing the liquid's chemical structure.
    • It is determined entirely by the liquid's observable appearance.
    • It must be identical whenever speakers use the same spelling and pronunciation.
    • It can depend partly on the speaker's environment, not just on internal mental states.

    The speakers match internally, but their encounters with the world differ.

    Show solution
    • It can depend partly on the speaker's environment, not just on internal mental states.

    This illustrates externalism: what a word refers to can depend partly on factors outside the speaker's mind. A speaker need not know the substance's chemistry for those factors to matter.

    In Newcomb's problem, a highly reliable predictor has already filled an opaque box with a large reward if it predicted you would take only that box; otherwise, it left the box empty. A transparent box always contains a much smaller reward. One argument favors taking both: this adds money whatever is already in the opaque box. Another favors taking only the opaque box, using the predictor's reliability to estimate the likely payoff. How do these arguments differ?

    • One assumes accurate predictions; the other assumes that your choice cannot be predicted.
    • One holds the existing contents fixed; the other compares likely outcomes using the prediction's reliability.
    • One treats both rewards as guaranteed; the other treats both boxes as potentially empty.
    • One aims to maximize money; the other aims to discover whether the predictor makes mistakes.

    Tedd fel a kérdést, hogy az egyes érvelések hogyan kezelik azt a tényt, hogy az előrejelzés korábban született.

    Show solution
    • One holds the existing contents fixed; the other compares likely outcomes using the prediction's reliability.

    A feszültség a cselekvések változatlannak tekintett tartalom melletti összehasonlítása és az egyes előre jelzett választásokhoz kapcsolódó kifizetések összehasonlítása között áll fenn. A feladvány nem követeli meg azt a meggyőződést, hogy egy későbbi választás megváltoztatja a múltat.
