lecture 5 slides Flashcards
What is the common sense view of science of Positivism & Popper?
- Science as aimed at truth, rational
- Progressive, cumulative
- Empirical observation as decisive
- Normative ideal: what science
ought to be like, how it ought to
work`
What is meant with context of discovery?
- The past is not a straightforward
preparation for the present: textbook
history isn’t real history. - The real history of science is messy
and complex. - It develops through revolutions
What is the Pre-paradigmatic phase?
- No consensus on problems, data,
methods, techniques, background
assumptions, success criteria, ‘good’
research, etc. - Everyone is ‘doing their own thing
What is a paradigm?
Exemplary scientific success that becomes a role model for
an entire (sub)field of science.
- Determines: problems to be solved, acceptable solutions
(success criteria), methods, techniques, experimental
procedures, theoretical framework, implicit know-how. - Defines a scientific community (who’s in and out?)
- ‘Indoctrination’ through formal scientific education and
training - Implicit knowledge
- Almost like a worldview, not a single theory but an entire
approach
example: Darwinian theory of evolution in biology
What is normal science?
Big questions are settled
* Consensus on paradigm: what the
problems are, how to solve them,
methods, etc.
* No discussion about fundamental, big
questions; paradigm isn’t tested or
called into question
* Puzzle solving; working out the details
* Not very spectacular; patience and
perseverance required
What are anomalies?
- In normal science, recalcitrant problems pop up, that resist
repeated attempts at solving them. - At first, scientists don’t notice or ignore these puzzles, but
after a while they become impossible to ignore. - Such problems challenge
the paradigm.
What is a crisis in reasearch?
- More and more scientists become
convinced that the anomalies cannot
be solved within the existing
paradigm. - Fundamental issues are put in
question again: - what exactly are the problems we’re
working on, the right methods,
background assumptions, data, success
criteria, concepts, etc.?
What is meant by a revolution?
*Transition from one paradigm to
another.
this isn’t a smooth or linear transition.
Transition from one paradigm to
another is not a sober, purely
rational process!
* Political, socio-cultural, and other
factors external to the contents of
science determine the outcome:
* power, money, reputation,
communication, etc.
* ‘Science advances one funeral at a
time’ (Max Planck
Why is there a trend of growing dissatification with existing paradigms?
- Existing paradigm does not function adequately regarding the
goals / objectives it previously performed. - The ensuing crisis is a prerequisite for revolution.
What are the procedures for reconciling a crisis?
There are no procedures for reconciling crisis.
- Different paradigms are incompatible.
- Superiority of one paradigm can’t be settled by logic, experiment,
observation, and rationality alone. - Non-rational persuasion / manipulation determines what becomes
the new paradigm.
What is Incommensurability?
According to Kuhn, paradigms are incommensurable,
‘uncomparable’:
* No neutral measuring stick, against which they could be compared
in terms of their truth, rationality, scientific success, etc
Scientists before and after a revolution live in different
worlds: “When paradigms change, the world changes with
them.”
Same concepts, different meanings
* Communication virtually impossible
* Literally a different world
What does not Incommensurability mean?
- That people do not understand
each other at all; - obviously, they can
communicate on some level… - That any and all comparison is
excluded
What does Incommensurability mean?
Some comparisons are
possible… but not epistemic
concerns, like ‘validity of
evidence’, ‘good arguments’, or
‘truth’.
* No neutral yardstick of
standards, norms, and values.
* Paradigm change is, in part,
irrational / illogical.
* Hence, comparison with
political revolution / conversion.
Are there Paradigms in social science?
Not strictly in Kuhn’s original sense.
* But perhaps in a slightly different sense?
- Paradigm 1:
Single dominant framework (worldview) - Paradigm 2:
Distinct scientific community with own institutional foundation - Paradigm 3:
Different schools of thought, theoretical perspectives within larger
community
