Question | Answer |
knowledge | true, justified belief |
rationalists | justified on the basis on intuition (think as lacking/without sensory experience) |
empiricists | justified on the basis of experience |
Kant | combined rationalism & empiricism the world aroud us is chaotic we experience the world we have certain innate ategories which help organize the information |
logic | methods for evaluating arguments |
argument | set of statements, each of which is either true or false |
conclusion | a statement that is affirmed (or not) by other statements |
premises | statements which affirm (or fail to) the conclusion |
logic | methods for evaluating arguments |
argument | a set of statements, each of which is either true or false |
Modus Ponens | Affirm the antecedent A->B A so, B |
Modus Tollens | Deny the consequent A->B ~B So, ~A |
Disjunctive syllogism | Deny one disjunct A v B ~A so, B |
Deductive argument | if argument is valid& premises are true conclusion must follow from premises |
validitiy/Invalidity | Conclusion logically follows from premises |
soundness | premises are true |
Deductive argument possibilites | valid and sound valid and not sound |
Inductive argument | argument is strong and premises are true, conclusion likely follows from premises (probabilistic) |
Strong/Weak | conclusion logically follows from premises |
soundness | premises are true |
abductive logic (retroductive explanations) | used when no universal laws (deductive) or probabilistic generalizations (inductive) exist |
nomothetic exxplanations | explain a broad class of phenomena rather than a specific situation or event high external validity low internal validity |
idiographic explanations | explain a single phenomenon in great detail at the expense of generalization low eternal validity high internal validity |
concepts | abstract representations of a pheomenon...an idea |
propsitions | statements positing associations between constructs |
logic | methods for evaluating whether the premises of an argument adequately support its conclusion |
ad-hoc classificatory system | a set of arbitrary categories constructed in order to organize and summarize phenomena |
taxonomy | system of logically related categories constructed to fit one or more phenomena |
conceptual framework | placement of descriptive categories into a structure of explicit propositions |
theoretical systems | combines taxonomies and conceptual frameworks relates descriptions, explanations, and predictions in a systematic way allows subsequent propositions to be derived |
Formal theory/axiomatic theory | axioms are basic propositions that are true (or not) a priori can be proved formally using logic and mathematics |
Good (versus bad) theory | precision parsimony falsifiability replicabiliy |
