Question English Answer English
a priori knowledge
start learning
preceding experience and observation; only by thinking about our way of observing events we can conclude that there is sth like causality; we give the meaning to those sequences by presupposing causality
synthetic a priori knowledge
start learning
"all phenomena have a cause"; "the world as we observe is three dimensional"
induction problem
start learning
the idea that only empirical data may count as good reasons for defending scientific claims
syllogism
start learning
valid, deductive argument
deductive-nomological model of science
start learning
we have a law from which we deduce our conclusions
induction
start learning
going from particular observations to general claims in inductive reasoning one goes from a set of particular observed phenomena and draws a conclusion about a general law applicable to phenomena which have not been yet observed
correspondence model of truth
start learning
a claim is true if it corresponds with reality
observational concept
start learning
i.e. we can observe that apple is green
theoretical concept
start learning
economical recession
What makes a theoretical concept for grasping non-observable phenomena into a good concept
start learning
Robustness, Fit, Predictability
Robustness
start learning
a concept should be usable in more than one context and it may mean that it will cover a set of phenomena
Fit
start learning
claims that one makes using these concepts, should fit into a more general theory
Predictability
start learning
using a particular concept, one should be able to make a trustworthy predictions about the occurrence of the phenomenon referred to nay the concept
Coherence Model of Truth
start learning
there will always be many reason-giving considerations that support the truth of a particular claim
logical positivism
start learning
knowledge should only be based on experience and observations; the main thesis of logical positivism is verificationism
verificationism
start learning
only claims which can be verified through empirical observations can have any meaning, therefore can be true or false
metaphysics
start learning
it is sth that we cannot verify through observations or sensory experience; something above physics that is driving everything; i.e. religion
3 grand epistemologies
start learning
Rationalism, Empiricism, Idealism
Rationalism
start learning
thinking is the basis for all knowledge; thinking is what crates knowledge; no empirical evidence
Empiricism
start learning
all knowledge comes from observation; it lacks causality, no theory, we cannot predict; we cannot transfer data into knowledge cuz we lack structure
Idealism
start learning
all knowledge comes from experience; the ability to structure experience is the idea; the problem is the question where these ideas come from
the linguistic turn
start learning
rather than assuming that we have the ability to know before we experience anything we now have sth very powerful called logic to organise our experience
All possible statements
start learning
logical nonsense, logical truth/analytical statements, metaphysics, empirical truth/synthetic statement
logical nonsense
start learning
all statatemsnt that we know ain't true before experiencing them
logical truth/analytical statements
start learning
we don't need to observe it cuz by definition it is true; "the bachelor is unmarried"
metaphysics
start learning
knowledge that we cannot verify through observations
empirical truth/synthetic statement
start learning
we can verify its truth through observations
synthetic statements
start learning
truth of statement depends on a matter of fact; through observation; this circle has diameter of 10 meter
analytic statements
start learning
truth of statement depends on the logical structure of a statement; logical analysis; this circle is round
logical reducibility
start learning
for every statement in the system of knowledge for that statement to be true one should be able to use logical and through logic to go back to your individual experience
the unity of science ideal
start learning
all knowledge should be able to put in a simple system
Problems in logical positivism
start learning
theoretical concepts, problem of induction
Theoretical concepts - LP problems
start learning
certain concepts cannot be reduced to observations alone; hence we employ intensional and extensional meanings of concepts
Intension
start learning
conjuztion of general properties that together define a concept
extension
start learning
the set of all real-life phenomena that together define the concept
reflective concepts
start learning
mąkę up the properties of a concept; firm performance determine earnings and ROE
formative concepts
start learning
made up of its respective properties; democracy can only be a democracy when there are free elections
pragmatic concession
start learning
allowing both theoretical concepts may happen when they explain something that is not apparent from observation alone and the use of these concepts lead to the development of new knowledge to be tested
induction
start learning
drawing general conclusions from a finite number of observations; new information can change the truth value of the conclusion
deduction
start learning
drawing specific conclusions through referring to general rules; new information has no influence upon the truth value of the conclusion
