EXAM Flashcards
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
The core of Zagzebski’s argument against
internalist analyses:
‘On internalist theories
the grounds for justification are accessible to the consciousness of the believer, and
Gettier problems arise when there is
nothing wrong with the internally accessible aspects of the cognitive situation, but there is a mishap in something inaccessible to the
believer. Since justification does not
guarantee truth, it is possible for there to be a break in the connection between justification and truth, but for that connection to be regained by chance.’
Internalism
justification is strictly a
function of what is available from the first-
person perspective
Externalism
justification can also include factors
available from the third-person perspective (like
causal relations between you and the clock)
Belief Independent
processes (like
vision) take external stimuli as inputs
and produce beliefs as outputs.
Belief dependent
processes like
inference and memory take prior beliefs
as inputs and produce new beliefs as
outputs.
Goldman’s externalist theory of
justification
Base, Recursive and Closure clause
What BonJour wonders is whether
basic beliefs can be characterized in
a way that will simultaneously make
them
both properly basic (not
dependent on anything else) and
really epistemically justified
Srinivasan sees internalism as making justification a
matter of your own private individual effort: “All
that is required to be internalistically justified is
individual conscientiousness
To be externalistically justified
requires, in part, the cooperation of the external
world: one must have
an undistorted relationship
to the relevant bit of reality
