Basic knowledge
doesn’t depend
on any other statement for its
justification
Non-basic knowledge
does depend
on some other statement for its
justification
What does non-basic knowledge also require?
absence of defeaters
A defeater
a truth
that would wipe out your
justification if you knew about it
What do Lehrer & Paxson think Non-basic knowledge is?
undefeated justified
true belief
Goldman’s new theory: reliabilism
Knowledge is true belief caused by a
reliable process or mechanism
What is it for a process to be reliable?
A reliable mechanism discriminates
the truth of p from relevant alternatives, forming a belief when p is true, but not when those relevant alternatives obtain
A possible world
a (complete) way things
are or could have been; it is a “maximally
inclusive situation”
☐-> “box-arrow”
to indicate the
subjunctive (or “counterfactual” conditional)
Robert Nozick’s basic* analysis of
knowledge
S knows that p if and
only if:
(1) p is true
(2) S believes that p
(3) If p were not true, S
would not believe that p
**(4) If p were true, S
would believe that p and
it would not be the case
that (S believes not-p).
Nozick and the sceptic agree that:
If SK really does obtain, we don’t know any of
the things we think we know about the world
around us.
Nozick also says:
We don’t track whether or
not we are in SK; so, we cannot know whether we are in SK.
Nozick’s sensitivity
condition
If p were false, S
would not believe that p
Plantinga analyses knowledge as
warranted true belief.
Zagzebski gives her general recipe for Gettier cases
- Describe a case of false belief
which has that some-other-factor
(and enough of it so that it would
count as knowledge if the belief
were true). - Now, add a stroke of luck that
ends up making the belief true
