Philosophy of Science Flashcards
Methodology:
the set of principles, procedures and rules for conducting a practice
Two crucial aspects to science:
- the generation of scientific theories
- the testing of those theories
3 founding figures of science
- Francis bacon
- Galileo Galilei
- Rene Descartes
What type of method did Bacon believe?
an inductive one
What type of method did Aristotle believe?
a deductive one
What is inference?
a type of logic or reasoning; it is a way of moving from one thought to another
Deduction:
if the premises are true, the conclusion is necessarily true
Induction:
if the premises are true, the conclusion is probably, but not necessarily, true
What are the 4 idols?
- Idols of the tribe
- Idols of the cave
- Idols of the market place
- Idols of the theatre
Idols of the Tribe:
errors generated by human nature
Idols of the cave:
individual errors generated from our own personal education, preferences and desires
Idols of the market place:
errors derived from our community, especially errors deriving from language
Idols of the theatre:
errors that derive from received philosophical systems
Scientific knowledge is empirical:
scientific knowledge must be gained through experience
What did Bacon put at the heart of science?
observation an experimentation
Bacons experimental(inductive) method:
- It should be conducted by someone in the correct, objective, frame of mind
- All measurements should (where possible) be made by instruments: objective, rather than subjective measurement
- It should limit the variables being tested, so that the causes of any observed effects can be unambiguously inferred
- Any effect should be repeatable under the same circumstances
Primary qualities:
those that can be measured and mathematically modelled e.g. mass, length and movement
Secondary Qualities:
qualities such as colour, taste, heat(not measured in numbers)
Did Hume like induction?
nope
Hume’s claim against induction:
Hume claims that we never actually witness the cause linking a cause with its effect, what we see are two separate events that are regularly conjoined (the connection is created by the mind, expectation)
Realism(naive):
the inductive method reveals how things really are, in ever greater detail as science progresses
Instrumentalism(anti-realism):
inductive knowledge is useful as it allows us to make more accurate/simple predictions
