What is Knowledge Flashcards
There are 3 types of knowledge, state them
- Ability
- Acquaintance
- Propositional
Explain each of the 3 types of knowledge and what they are
Ability knowledge = eg ‘i know how to ride a bike’ (possessing a certain skill)
Acquaintance knowledge = eg ‘ I know Japan’ (because you’ve been there/acquainted with it)
Propositional knowledge = eg ‘ I know that elephants are heavier than ants’ (describes how things are)
- A proposition is a declarative statement or more accurately wat is expressed in a declarative statement. They usually go after phrases ‘ i know that…’
What does JTB stand for?
Justified True Belief
Explain theory No.1 the Tripartite theory of knowledge - Justified True Belief ( JTB )
JTB = the Tripartite theory of knowledge
States that knowledge is a Justified True Belief so for someone to possess knowledge they must ;
- Have a reason for believing it (justification)
- Believe it
- Truth (it must be true)
The theory set out; "I know that 'P'" "The proposition 'P' is true" "I believe in 'P'" "My belief in 'P' is justified"
“i know that ‘P’ if these conditions are met / fulfilled and they are”
Therefore “I know that ‘P’”
Tripartite definition doesn’t require the belief (B) to be ‘certain’ however, whilst it can be argued ‘knowledge’ must be certain + we only really ‘know’ something if we can be certain of it. To say a belief is justified doesn’t equate to certain because we have good reason to believe many things possible to doubt.
Explain what is meant by Necessary & Sufficient Conditions.
Sufficient conditions = Each condition is necessary for knowledge thus you cannot just have 2 out of the 3 conditions ie Justified and Belief because only the joint 3 conditions together are sufficient at ‘guaranteed knowledge’.
A proposition that is simply a ‘true belief’ but doesn’t have any justification for example is not satisfactory as a definition for knowledge as believing somethings ‘true’ can be found/held on irrational grounds and therefore by inputting justification as our beliefs and truths will be required to be rational
Necessary = Knowledge can be true with at least 1 of the 3 conditions ie if a proposition only had 1 out o the 3 conditions such as Justified it can make knowledge possible however you always need at least on part present.
Explain the Criticism of the Tripartite definition of knowledge ‘ The Belief condition’
Argument ;
- Do we really need to believe something in order for it to be true, can we have knowledge without Belief? Many philosophers argue knowledge is about how someone acts rathe than what someone believes or entertains
John example - john the student is very nervous + unconfident going into exam and thinks has got all the answers wrong and yet he comes out with 100% right due to his revision
Reply of criticism - John has unconscious belief - he does know the answers completely he just doesn’t know that he does but when we ascend to something that is a form of belief and unconscious belief is still belief.
Explain Theory No.2 - K = JTB + Infallibility ( I )
JTB + Infallibility removes luck completely from the process if justification is only what is infallible (impossible to prove wrong) The aim being to make jistfication so strong yet its impossible for a justified belief to be false. Therefore Gettier cases would become impossible + mistakes/luck plays no role in equasion
No one can know what is false. Thus for justification to secure knowledge it must guarantee truth. Im justified in believing that ‘P’ ie something concerning my own introspection but its possible I’m mistaken if its not something infallible. Therefore Infallibalism stands + is true.
There’s no doubt between my internal belief and an external fact so ‘ I am i pain’ is infallible because its your ‘ Introspective thoughts’ within your internal mind (Introspection) and your considering your own mind not external world (thus soon as we move outside our internal mind things become doubtful)
Some infallibility claim Knowledge isn’t a kind of belief as its a separate thing beliefs only occur when doubt is possible thus knowledge is not a form of belief.
Explain the Criticism of Theory No.2 - JTB + Infallibilism
Infallibilism is too strict
- Limits what we actually know so that only logical truths + direct sensations ie pain can be true/knowledge
- It rejects instincts ie ‘knowing someone’s outside my window’ but they would say we don’t know it whatsoever which can be problematic
- We end dup w a radical idea of what knowledge is.
Explain Theory No.3 - Knowledge = JTB + No false Lemmas ( N )
Knowledge = JTB + N Lemmas = a belief or assumption that is held to be true + used to justify a piece of knowledge. No false Lemmas argues knowledge is JTB as long as / whereby the justification is not based on any false lemma. If a belief is based on a 'false lemma' even though it may feel like knowledge it is not
Because before with just JTB = K it leaves possibility for things to be luckily true however NO false lemmas doesn’t allow this. ie in Gettier’s Smith & Jones example it doesn’t work under JTB+ N because it relies on a false lemma(the president of the company) so perfectly counters Gettier’s example as the only reason Jones thought smith would get the job was due to owner saying saying the man w 10 coins would get the hjob (false lemma)
Zagzebski describes a case based on induction. Dr Jones has good evidence her patient Smith is suffering from virus X as the symptoms are all consistent with Smith having virus X + no other virus produces such symptoms so Jones therefore believes he has virus X (justified belief) however Smiths symptoms are caused by him having unknown virus Y but by chance Smiths just caught virus X so recently thus hasn’t caused any symptoms + didn’t show on lab tests. Dr Jones assuming Smith had virus X is completely justified, and she beliefs it however it wasn’t true so wasn’t knowledge. However it was because of the false lemma (Dr Jones evidence from labs which only showed virus X that misleads her) Therefore JTB + No false lemmas is sufficient for knowledge not JTB alone.
Explain the criticism of JTB + No false lemmas
What about the Fake Barn example - despite having JTB+ N it was still luckily true that he looked at the only barn that was actually real and could have very easily been completely wrong.
This wasn’t knowledge + was only luckily true.
What is a ‘Paradigm’?
Paradigm = a persons view of the world
Is justification ( J ) a necessary condition?
For example what about a person who looks at people and knows their birthdays immediately without reason + justification.
Ie human nature/instinct such as feeling somethings wrong or that someones watching you doesn’t have rational justification behind it but can be accurate.
Thus do we need to worry or concern ourselves w justification?
Explain the Gettier criticism of the Tripartite definition of knowledge (JTB) Does JTB = K ?
Gettier objection = the Smith + Jones example proves JTB doesn’t equal Knowledge as its possible to have justified true belief and not knowledge
Gettier begins claiming a Deductive argument preserves justfication (your reason for believing he premises also = your reason for believing the conclusion).
Two men attend a job interview. Smith + Jones. Smith has excellent reason to believe (justifiably) that Jones will get the job as smiths been told by the employer and been informed the man with 10 coins in his pocket will get the job and has counted that Jones has 10 coins in his pocket. Thus both his beliefs are justified + so Smith deduces Jones will get the job (He believes it) however Jones doesn’t get the job, smith gets the job so checks his pockets to see he has 10 coins in his pocket - so smiths belief happened to also be true. Yet smith didn’t possess knowledge whatsoever as he was wrong despite having all the sufficient conditions.
Explain the advantages of JTB + Infallibilism
- Its not open to Gettier’s counter examples and takes luck completely out of the equation so knowledge is actually knowing things
- Knowledge needs to be a certain which is absolute and it is very clear (has to be internal mind not other ppls)
Explain the theory of Reliabilism - RTB = knowledge ( Reliability + Truth + Belief )
Reliabilism TBR = K takes justification out of the conditions, stating ‘knowledge is a true belief that is produced by a Reliable process’
You know that P if;
- P is true
- You believe that P and
- Your belief is caused by a reliable cognitive process
Reliable Cognitive process = is just one that produces a high percentage of true belief eg perception, memory
A false belief caused by a reliable process is not knowledge. The idea of a reliable process replaces the justified condition because true beliefs caused by this reliable process count as knowledge.
Thus an advantage of Reliabilism is that it allows young children + animals to have knowledge which is rgublky true as It would be idd ti deny that they do and their beliefs are caused by a reliable cognitive process.
