Epistemology Flashcards
(17 cards)
Analytic
A proposition that is true in meaning of the words
Eg: A bachelor is an unmarried man, a square has 4 sides
Synthetic
A proposition that is not analytic, but true or false based on how the world is
Eg: Snow is white, the Eiffel tower is in Paris
Necessary
A proposition which is always true as it could not have been otherwise
Eg To read an essay I need to know how to read, All bachelors are unmarried
Contingent
A contingent truth is a propostion that could either be true or false, a state of affairs that may or may not be true based on the context
Eg The cat is black, It is raining
A priori
Knowledge that doesn’t require experience to be known to be true or false
A posteriori
Reasoning or knowledge which can only be known to be true or false through sense
Matters of fact
Contingent truths that only deal with experience and can be denied coherently.
Eg It is snowing
Relation of Ideas
Truths that can be known independently from experience and are intuitivly and demonstrably certain
Eg 2+2=4
Humes Fork
A way of categorising propositional knowledge claims into two key branches - matters of fact and relation of ideas. All truth-apt statements must be one of these
Valid vs invalid argument
A valid argument is a deductive argument where all the premises entail the conclusion, whereas an invalid argument does not
Inductive vs deductive argument
An inductive argument is one in which if all of the premises are true then the conclusion is unlikely to be false, whereas a deductive argument is one where if all the premises are true the conclusion cannot be false.
Problem with the Justified true belief
“Lucky true belief”
Necessary condition
One that must be true for another condition to occur
e.g sitting the exam is a necessary condition for passing the exam
Sufficient condition
One that, if true, guarantees a certain outcome
E.g: Suppose it is true that it is both raining and sunny. This is a sufficient condition for “it is raining” to be true.
3 types of knowledge
Ability (how)
Acquintance (of)
Propositional (that)
