Problem 6: philosophy of science Flashcards
Popper’s ideas about knowledge
knowledge is
-not justified (not theory can be subject to all possible outcomes, there can always be a test that can falsify the theory)
-not true (knowledge is verisimilitude = truth likeness, it can never be 100% true)
-not belief (knowledge is not belief, but objective truth)
Popper’s answer to what a scientific vs a pseudoscientific method is
there are many confirmations for pseudoscientific theories out there, therefore falsification is very important
what influences falsifiability
the more specific, the more universal, predictive theories
according to popper science begins and ends with problems, explain
P1 -> TS1 -> EE -> P2
starting problem -> tentative solution -> error eliminating test -> creates new problem
popper’s criticism on positivism
-there is always a chance that come unconnected test might falsify the problem
-there is no way to prove that the statement is false, therefore it cannot be true
-first look at the problem in order to know what to observe
Kuhn’s view on science
-criticised popper for only focusing on falsification
-looked at whether theories actually worked
-called scientists puzzle solvers (science = puzzle)
-focus on paradigms: a general idea/ consensus that is currently being accepted
criticism on Kuhn:
-very vague
-had many different definitions for what a paradigm is
phases of science
1 pre paradigm period:
-debates about problems and solutions
2 paradigmatic (mature science) period:
-agreements on problems and methods
-dogmatic attitude
-progress in this stage
3 revolutionary (extraordinary science):
-reaching closer to actual truth
-scientific revolutions
-gestalt switch (a new paradigm alters perceptions)
what does Kuhn mean when he says that paradigms are incommensurable
paradigms do no have a joint measurability, they do not talk about equal problems therefore
characteristics of pseudoscience
-belief in authority
-unrepeatable experiments
-handpicked examples
-unwillingness to test disregard of refuting information
-built-in subterfuge (if the theory is tested, the result can only confirm the theory and never disprove it)
-explanations are abandoned without replacement
