10.The thesis (or principle) of epistemic closure is the claim that knowledge and justification are closed under known entailment.What does this mean?Explain why on Nozick's tracking the truth account, the thesis of epistemic closure is false.Explain why on Dretske's relevant alternatives account, the thesis of epistemic closure is false.How would BonJour reply to Nozick or Dretske?

 

11.What is a modus ponens argument?What is a modus tollens argument?

 

12.Suppose that BonJour thinks he has good reason to believe in an external world. The reason would have to be at least part a priori.Why?On his own account, could he be mistaken about the a priori part of the justification?How would he reply to someone who was a skeptic about a priori justification?

 

13.How does BonJour's discussion of Descartes's "light of nature" show that BonJour is denying that Descartes had it.But if Descartes thought he did have it and did not, then won't any response to skepticism be liable to the same problem?

22.What is Rortyís response to skepticism?What is BonJourís response to Rorty?

 

23.What presumption is BonJour making in his understanding of justification?Explain how this presumption makes the other views he discusses seem to be surrendering to skepticism?What alternatives are there to his presumption?How might those who hold the opposing views reasonably deny that they are surrendering to skepticism?

 

24.What is a pragmatic theory of truth?of justification?According to BonJour, what is the problem with the pragmatic theory of justification?How would a pragmatist respond?

 

25.Rorty's view has three parts.Explain why the third amounts to a pragmatic theory of truth.What is the general problem for pragmatic theories of truth that we discussed earlier?How does this apply to Rorty's theory?

 

26.What kinds of skepticism does BonJour accept as unanswerable?

 

27.On BonJour's account, what would be necessary for someone to be able to have justified beliefs about the external world?Is there anyone in the world who satisfies BonJour's requirements?Explain.
