Philosophy of Evidence, Belief, and Evil: Key Arguments and Concepts

What is Corvino's overall argument against the fact/opinion distinction?

Attempts to define the distinction fail to cleanly separate facts from opinions, and it can encourage irresponsible inquiry by making people think opinions don't require evidence.

What is Corvino's conceptual-analysis approach?

Corvino considers possible definitions of 'fact' and 'opinion' and tests whether they provide the necessary and sufficient conditions needed to distinguish the two categories.

What is an objection/problem with defining opinions as claims that cannot be proven?

Many things we call facts cannot be proven with absolute certainty, while some opinions can be strongly supported by evidence.

What is Corvino's irresponsible-inquiry worry?

Labeling something 'opinion' can encourage people to think it does not need evidence or justification, stopping responsible investigation.

What should we focus on instead of simply asking 'fact or opinion'?

We should ask whether the claim is true or false, what evidence supports it, and whether we have good reasons for believing it.

What is Clifford's argument for evidentialism?

It is wrong to form beliefs irresponsibly; believing without sufficient evidence is an irresponsible way of forming beliefs.

What conclusion does Clifford defend?

We have an ethical responsibility not to believe claims without sufficient evidence.

How does Clifford's shipowner example support evidentialism?

The shipowner suppresses doubts about his ship's safety, demonstrating irresponsible belief formation.

What is the 'what if the ship arrives safely?' objection to Clifford?

If the shipowner's belief turns out to be true, perhaps there was nothing morally wrong with believing the ship was safe.

How does Clifford respond to the ship arriving safely objection?

A lucky outcome does not justify an irresponsibly formed belief; the shipowner lacked sufficient evidence.

What is the 'trivial/private beliefs' objection to Clifford?

It seems too strong to say every unsupported belief is morally wrong, especially when a belief seems insignificant.

How does Clifford respond to the trivial-belief objection?

Unsupported beliefs develop a habit of credulity, making us less careful about investigating future beliefs.

What is Nguyen's basic argument about epistemic bubbles and echo chambers?

Epistemic bubbles exclude relevant outside voices, while echo chambers discredit outside voices, making escape harder.

What is the key difference between a filter/epistemic bubble and an echo chamber?

A bubble systematically excludes outside voices, while an echo chamber systematically discredits them.

Why can adding information help someone escape an epistemic bubble?

The person's problem is lack of exposure; introducing reliable sources gives them access to missing information.

What objection asks why we cannot simply give an echo-chamber member more evidence?

If false beliefs result from bad information, supplying better evidence should correct those beliefs.

How does Nguyen respond to 'just give them more evidence'?

Echo-chamber members distrust outside sources, so additional evidence may be rejected.

What is the argument behind intellectual judo?

Echo-chamber members expect outsider criticism, which can reinforce their beliefs when outsiders criticize.

What does intellectual judo show about echo chambers?

Counterevidence does not weaken an echo chamber; distrust can transform it into support for existing beliefs.

What does Derek Black illustrate in Nguyen's argument?

Derek Black illustrates that escaping an echo chamber may require rebuilding one's system of trust.

What is an epistemic reboot?

A process of reconsidering trusted sources and rebuilding one's epistemic framework.

What is the conclusion of Nguyen's echo-chamber argument?

Echo chambers are difficult to escape because they manipulate trust, requiring an epistemic reboot.

What is Fricker's basic argument concerning testimonial injustice?

Speakers should receive credibility appropriate to the evidence; prejudice can cause an undeserved credibility deficit.

What is the central case of testimonial injustice for Fricker?

Identity-prejudicial credibility deficit: a speaker receives less credibility due to prejudice concerning their social identity.

What objection asks whether every credibility deficit is testimonial injustice?

People can mistakenly underestimate someone's credibility without prejudice.

How does Fricker respond to the 'every credibility deficit' problem?

Not every credibility deficit is testimonial injustice; the central case involves prejudice that wrongfully undermines someone.

How does Tom Robinson support Fricker's account of testimonial injustice?

Racial prejudice causes the jury to give Tom less credibility despite evidence supporting him.

What is the fine-tuning argument?

The universe is fine-tuned for life, and traditional theism is the best explanation of this fine-tuning.

What type of argument is the fine-tuning argument?

Abductive reasoning, or inference to the best explanation.

Why does the fine-tuning conclusion say 'probably'?

The argument is abductive rather than deductive, identifying the best explanation rather than guaranteeing its conclusion.

What is the chance objection to the fine-tuning argument?

The universe may simply have happened by chance to possess life-permitting constants, so God may not be necessary to explain fine-tuning.

How does the firing-squad example respond to the chance objection?

If many shooters all miss you, chance is possible, but the extreme coincidence still calls for an explanation.

What does the firing-squad example demonstrate?

Merely showing that an event could happen by chance does not show that chance provides the best explanation of that event.

What is the anthropic-principle objection to fine-tuning?

We should not be surprised to observe a life-permitting universe because if the universe did not permit life, we would not exist to observe it.

What is a response to the anthropic-principle objection?

Explaining why observers can only observe a life-permitting universe does not necessarily explain why a life-permitting universe exists.

How does the firing-squad example relate to the anthropic principle?

A survivor can only observe a firing squad after surviving, but that does not explain why all the shooters missed.

What is the multiverse objection to the fine-tuning argument?

If many universes exist with different constants, it becomes less surprising that at least one universe permits life and that observers find themselves there.

Which premise of the fine-tuning argument does the multiverse mainly challenge?

P2: that traditional theism is the best explanation of fine-tuning.

What is a possible response to the multiverse objection?

The mere possibility of a multiverse does not establish that a multiverse actually exists.

What is the 'deeper fundamental laws' objection to fine-tuning?

Perhaps deeper laws of nature determine the apparently fine-tuned constants, meaning the constants could not actually have been otherwise.

How does the deeper-laws objection challenge fine-tuning?

It challenges the assumption that the observed constants genuinely require a separate explanation based on chance or design.

What is the objection that theism may be non-explanatory?

Saying 'God did it' may not explain why God would create a universe with these particular life-permitting conditions.

What is a possible response to the claim that theism is non-explanatory?

A defender can argue that conscious life has value and that a good God could therefore have a reason to create conditions capable of supporting conscious life.

What is the logical argument from evil?

P1: If an omnipotent, omniscient, and omnibenevolent God exists, God and evil must be compatible only if God could have a sufficient reason to permit evil. P2: The logical problem claims no such compatibility exists. C: Therefore, the existence of evil would rule out the traditional God.

What is the main conclusion of the logical problem of evil?

The traditional God and the existence of evil are claimed to be logically incompatible.

What must a response defeat to answer the logical problem of evil?

It only needs to show a logically possible way that God and evil could coexist.

What is Plantinga's Free Will Defense?

P1: Free will is a great good. P2: Genuine freedom includes the possibility of choosing evil. P3: God cannot guarantee genuinely free creatures always choose good without undermining freedom. C: God and evil can logically coexist.

What conclusion is Plantinga trying to establish with the Free Will Defense?

The existence of an omnipotent, omniscient, omnibenevolent God is logically compatible with the existence of evil.

What is the omnipotence objection to Plantinga's Free Will Defense?

If God is all-powerful, why couldn't God create people who are genuinely free but always freely choose good?

How does the Free Will Defense respond to the omnipotence objection?

Omnipotence does not include doing what is logically impossible.

What is the divine-foreknowledge objection to free will?

If an omniscient God already infallibly knows every future choice, it seems impossible for a person to choose differently.

What is the response to the divine-foreknowledge objection?

God's knowing what someone will freely choose does not necessarily cause or determine that choice.

What is the natural-evil objection to the Free Will Defense?

Human free will may explain moral evil, but diseases, earthquakes, and other natural evils do not appear to result from human free choices.

What is a possible Free Will Defense response to natural evil?

It is logically possible that natural evil results from the free actions of nonhuman free creatures.

What is the objection to explaining natural evil through nonhuman free creatures?

Showing that such an explanation is possible does not give us reason to believe it is actually true.

Why can mere possibility matter for the logical problem of evil?

The logical problem claims God and evil cannot possibly coexist, so one coherent possible explanation can undermine the alleged logical contradiction.

Why is mere possibility weaker against the evidential problem of evil?

The evidential problem concerns what is probable or supported by evidence.

What is the evidential argument from evil?

P1: A perfectly good, knowing, powerful God would not permit gratuitous evil. P2: Some observed evil appears gratuitous. P3: This gives us reason to think some evil may actually be gratuitous. C: Therefore, probably the traditional God does not exist.

What is gratuitous evil?

Evil or suffering for which God has no morally sufficient reason to permit it.

What conclusion does the evidential problem of evil make?

The amount or type of apparently gratuitous evil in the world makes the existence of the traditional God less probable.

What is a major response to the evidential problem of evil?

Our inability to identify God's reason for permitting particular suffering does not prove that God has no morally sufficient reason.

What is the critic's reply to 'God may have reasons we don't understand'?

Even if unknown reasons are possible, widespread apparently pointless suffering may still count as evidence against God's existence.

What is the key difference between the logical and evidential arguments from evil?

The logical argument claims God and evil cannot coexist; the evidential argument claims observed evil makes God's existence less probable.

Which arguments should I know premise-by-premise for the midterm?

Corvino's fact/opinion argument, Clifford's evidentialism, Nguyen's echo-chamber argument, fine-tuning, logical problem of evil, Plantinga's Free Will Defense, and evidential problem of evil.
