- C
The standards for saying someone knows can vary with the conversational context.
- D

- A
Treating induction as a practical or basic method without demanding a proof that it must succeed.
- B
Proving induction deductively from the fact that the future must resemble the past.
- C
Using probability to measure how evidence supports competing hypotheses.
- D
Asking whether induction is the best available method for achieving reliable expectations.

Why does the argument “Induction has worked in the past, so it will work again” fail to provide a non-circular justification of induction?
- A
It denies that people actually use past cases to form expectations.
- B
It relies on induction to support induction, assuming the reliability it aims to justify.
- C
It assumes that all future events are logically entailed by past observations.
- D

A philosopher responds to skepticism by arguing that certain facts the skeptic questions are necessary for coherent experience or thought. What kind of argument is this?
- A
It argues that every belief must be supported by an endless chain of reasons.
- B
It claims that behavior resembling one's own is evidence of another person's pain.
- C
It argues that some facts questioned by the skeptic are necessary conditions for coherent experience or thought.
- D
It holds that standards for knowledge change with conversational context.
Compare foundationalism, coherentism, and infinitism as responses to the problem of epistemic regress. Explain how each view structures the support for justified belief.
In an ordinary conversation, someone says they know there is a desk nearby. During a philosophical discussion, the conversation shifts to whether they can rule out an elaborate skeptical scenario. Which view explains why the standard for saying “knows” may change with this shift?
- A
Foundationalism
- B
Contextualism
- C
Fallibilism
- D
Infinitism
A fallibilist can maintain that a person knows something even if the person’s evidence does not rule out every conceivable possibility of error.
- A
True
- B
False
A person notices that their own pain is associated with certain behavior and that another person behaves similarly when apparently hurt. Which traditional reply to the problem of other minds uses this reasoning?
- A
Direct access: each person directly experiences the other person’s thoughts and feelings.
- B
Proof by impossibility: similar behavior proves that mindless beings cannot exist.
- C
The argument from analogy: similar behavior is evidence that another person has experiences like one’s own.
- D
Identity of thought: people who use similar words must have identical thoughts.
What theory of justification says that beliefs are justified through their mutual support within a coherent system, rather than by resting on a single foundation?

- A
The belief may count as knowledge if it was produced by a reliable process.
- B
The belief cannot count as knowledge unless the person has eliminated every imaginable error.
- C
The belief is justified only if it rests on an unsupported foundational belief.
- D
The belief is knowledge only if the person can directly experience another person’s thoughts.
