Epistemology I - Analysis and possibility of knowledge Flashcards
Belief condition
S knows that p only if S believes that p
So: belief is a necessary belief for knowledge
Brain In a Vat
Skeptical alternative that you do not know you have hands because it is possible that all you are is not a person of flesh and bones, but rather a Brain In Vat stimulated in such a way as to have all your experiences
Cartesian skepticism
Defining skeptical problems in terms of skeptical alternatives
Causal analysis
S knows that p if and only if:
(1) S believes that p
(2) p is true
(3) the fact that p is causally connected in an appropriate way in S’s belief that p
Closure
If S knows that p, and p rules out q, then S knows that q is ruled out
Contextualism
View that if a skeptical alternative q is contextually salient, S doesn’t know that p
Defeater
True proposition q, such that if S were justified in believing that q, S would not be justified in believing that p
Epistemic luck
It is accidental/coincidental/fortuitous that S has a true belief that p
Epistemic subject
Person or group that believes or knows that p
Traditionally represented with S
Epistemology
Domain of theoretical philosophy that deals with the kinds, analysis, possbility, structure, value, sources and dimensions of knowledge
Gettier problem
The traditional analysis of knowledge in terms of justified true belief is lacking because there are cases in which justified belief can stem from epistemic luck
Justification condition
S knows that p only if S’s belief that p is justified
So: justification is a necessary condition of knowledge
No defeaters analysis
S knows that p if and only if
(1) S believes that p
(2) p is true
(3) p is justified for S
(4) There is no true proposition q such that, if S were justified in believing that q, S would not be justified in believing that p
No false lemmas analysis
S knows that p if and only if
(1) S believes that p
(2) p is true
(3) p is justified for S
(4) S’s ground for believing p does not include any false proposition q
Relativism about truth
View that there are no absolute truths -> truth is always relative to a believer or group of believers
Relevant alternatives approach
View that S can only know that p only f S can rule out any alternative explanation q that is relevant in the context
Note: skeptical alternatives are never considered to be a relevant alternative
Sensitivity condition
S knows that p only if it is true -> if p were not true, S wouldn’t believe that p
Skeptical alternative
q is a conceivable and thereby logically possible alternative explanation to p, which is incompatible with p, and cannot be ruled out
Traditional analysis
Tripartite analysis/JTB-analysis:
S knows that p if and only if
(1) S believes that p
(2) p is true
(3) p is justified for S
Belief, truth and justification are individually necessary and jointly sufficient for knowledge
Truth condition
S knows that p only if p is true
So: truth is a necessary condition of knowledge
Plato does not agree with truth relativism, but employs another system to attain truth. What is this method?
Correspondence theory of truth -> something is true when it corresponds with reality
What can be seen as a weakness of truth relativism?
It does not distinguish between holding something true and something being true
How does Plato do away with truth relativism?
He points out the weakness of truth relativism:
-Either truth relativism is relatively true -> argument lacks for and is not convincing to those who were not already convinced in the first place
-Or truth relativism is absolutely true, in which case there is at least one truth that is not relatively but absolutely true, and the system of truth relativism breaks down
What is the function of the justification condition in JTB analysis?
To rule out epistemic luck
