  • DEMARCATION
  • What is the core business of the philosophy of
    science?
  • 2. FALSIFICATION

  • To what extent is the sociology of science a
    radicalization of the philosophy and history of
    science?

1. DEMARCATION

6
SCIENCE AS A CONTESTED CONCEPT
  • 1. The reference of this concepts is not always
    clear (example the debate between darwinists and
    creationists).
  • 2. This concepts has a normative character
    (example the debate about reproductive cloning).
  • 3. Some people use this concepts as a weapon
    (example the debate about the climate changes).

7
SCIENCE AS OBJECT OF RESEARCH AND REFLECTION
  • Philosophy of science the creation of and
    reflection on ideal models of science.
  • History of science the study of the development
    of science.
  • Sociology of science the study of what
    scientists do and how their actions are
    culturally embedded.

8
THE IDEAL AND THE REAL
  • The philosophy of science is more concerned with
    the ideal and the history and sociology of
    science with the real.
  • The question What is good science? leads to the
    tension between how science is and how it should
    be.
  • Nowadays the philosophy, history and sociology of
    science have a three-cornered relationship.

9
TOWARDS CRITERIA OF DISTINCTIVENESS
  • Central question of the philosophy of science
    what counts as being scientific?
  • Cognitive demarcation how to distinguish
    scientific knowledge from other forms of
    knowledge?
  • Social demarcation what is the difference
    between the social interactions of scientists and
    the social interactions of people who have
    another occupation?
  • Are there any criteria to make these demarcations?

10
STANDARD VIEW OF SCIENTIFIC KNOWLEDGE
  • Vienna Circle gt a group of early 20th century
    philosophers who studied the sciences.
  • Names Rudolf Carnap, Moritz Schlick and Otto
    Neurath.
  • They articulated the standard view of scientific
    knowledge logical positivism.

11
TWO KINDS OF MEANINGFUL STATEMENTS
  • Analytical statements
  • - are truth or untrue because of the meaning of
    the words (example A circle is round)
  • - have an a priori character.
  • - belong to the domain of logic, mathematics
    and philosophy.
  • Synthetic statements
  • - are truth or untrue when they are base upon
    the perception of the senses.
  • - have an a posteriori character.
  • - belong to the domain of the emprical sciences.

12
VERIFICATION
  • Metaphysics gt meaningless synthetic statements
    (example God exists).
  • A criterion of demarcation the principle of
    verification gt if a statement is capable of being
    verified it is scientific, i.e. it must be
    possible to control via the senses whether a
    statement is truth.
  • Induction the inferference of universal
    statements (theories and hypotheses) from
    singular statements (based on observations and
    experiences).
  • Logical positivism gt science is based on
    empirical facts and logic.

13
THEORIES
  • Theories consist of universal statements.
  • Theories help people to interprete or explain
    phenomena in the world.

14
2. FALSIFICATION
15
FROM INDUCTION TO DEDUCTION
  • No scientific theory can ever be deduced from
    observation statements, or be described as a
    truth-function of observation statements.
  • Karl Popper

16
KARL POPPER (1902-1994)
  • Main works
  • Logik der Forschung (1934).
  • The Open Society and Its Enemies (1945).
  • Objective Knowledge (1972).

17
TWO POINTS OF CRITICISM
  • THE PROBLEM OF INDUCTION
  • THE ILLUSION OF IMMEDIATE OBSERVATIONS, i.e.
    PERCEPTIONS WHO ARE NOT MEDIATED BY THEORIES

18
THE PROBLEM OF INDUCTION
  • Theories can never be inferred from observation
    statements, or rationally justified by them.
  • Induction cannot be logically justified no
    matter how many white swans you observe, it does
    not justify you to conclude that all swans are
    white.
  • There is no rockbottom of knowledge.

19
OBSERVATION IN THE LIGHT OF THEORIES
  • The inductivist prejudice there is a phenomenal
    language free of theories and different from a
    theoretical language.
  • The ordinary language is full of theories.
  • Observation is always observation in the light of
    theories.
  • What one observes is determined by his or her
    previous experiences, knowledge and expectations.

20
FALSIBIABILITY
  • Science consists largely of problem solving and
    not on observation.
  • Deduction replaces induction, i.e. singular
    statements (predictions) are deduced from a
    theory.
  • The theory is scientific only if one can falsifiy
    it by a conceivable event.
  • A theory is the best available theory until it is
    falsified and/or superseded by a better theory.
  • Falsification subsitutes verification.

21
THOMAS KUHN (1922-1996)
  • Main works
  • The Structure of Scientific Revolutions (1962).
  • The Essential Tension (1977).
  • Black Body Theory and the Quantum Discontinuity
    (1978).

22
THE DEVELOPMENT OF SCIENCE
  • Philosophy of science how science ought to
    develop gt progress guaranteed by the scientific
    method.
  • History of science how science really developed.
  • Kuhn gt the development of a science is not
    uniform but has alternating normal and
    revolutionaryphases.

23
NORMAL SCIENCE
  • Normal science gt resembles the standard
    cumulative picture of scientific progress.
  • Puzzle-solving the puzzle-solver expects to have
    a reasonable chance of solving the puzzle
    puzzles and their solutions are familiar and
    relatively straightforward.
  • Normal science is cumulative and presupposes a
    strong commitment of the members of a scientific
    community to shared theories and practices.
  • The tension between the desire for innovation and
    the necessary conservativeness of most scientists.

24
REVOLUTIONARY SCIENCE
  • Revolutionary science implies a revision of the
    existing scientific beliefs and practices and is
    not cumulative.
  • Not all the achievements of the preceding period
    of normal science are preserved in a revolution.
  • Anomalies are not anymore ignored or explained
    away.
  • Crisis the accumulation of particularly
    troublesome anomalies caused serious problems for
    the existing theories and practices.
  • There is a search for new theories and practices.

25
PARADIGM
  • Paradigm gt a common frame of reference and an
    exemplary way of doing research.
  • New paradigm gt a new puzzle with another approach
    to solve it and based on a so-called
    Gestaltswith.
  • Incommensurability gt theories which dont share a
    common measure gt different standards of
    evaluation, etc.

26
3. CONSTRUCTION
27
DIFFERENCES BETWEEN SCIENCES
  • What are the differences between sciences?
  • Double hermeneutics the object of the social
    sciences interpret itself.
  • Are the sociale sciences more irrational, i.e.
    subjective than the natural sciences?

28
RATIONALITY
  • Irrationality is always an accusation made by
    someone building a network over someone else who
    stands in the way.
  • Bruno Latour

29
BRUNO LATOUR (1947)
  • Main works
  • Laboratory Life The Construction of Scientific
    Facts with Woolgar (1979).
  • Science in Action (1987).
  • Politics of Nature How to bring the Sciences
    into Democracy with LaTour and Porter (2004).

30
ASPECTS OF SCIENTIFIC RESEARCH
31
PANDORAS BOX
  • Philosophy of science and history of science
    focuses on ready made science.
  • Latour focuses on science in the making.
  • One should open pandoras box.
  • This makes clear that scientific facts are social
    constructions.

32
SCIENCE IN ACTION
  • Scientists are involved in controversies.
  • The fate of the facts they present are in the
    hand of later users.
  • To strengthen their statements they are in need
    of allies.
  • They have to mobilize human and non-human beings
    to create strong associations.

33
METHOD
  • We study science in action and not ready made
    science or technology to do so, we either arrive
    before the facts and machines are blackboxed or
    we follow the controversies that reopen them.
  • To determine the objectivity or subjectivity of a
    claim, the efficiency or perfection of a
    mechanism, we do not look for their intrinsic
    qualities but at all the transformations they
    undergo later in the hands of others.
  • Since the settlements of a controversy is the
    cause of Natures representation, not its
    consequence, we can never use this consequence,
    Nature, to explain how an why a controversy has
    been settled.
  • Since the settlement of a controversy is the
    cause of Societys stability, we cannot use
    Society to explain how and why a controversy has
    been settled. We should consider symmetrically
    the efforts to enrol human and non-human
    resources.

34
ULRICH BECK
  • Main works
  • Risikogesellschaft. Auf dem Weg in eine andere
    Moderne (1986).
  • Die Erfindung des Politischen (1993).
  • Weltrisikogesellschaft (2007).

35
THE WORLD RISK SOCIETY
  • Social and economic progress is triggered by
    science and technology.
  • The unintended consequences lead us to a second
    modernity.
  • The problems we produced by ourselves reflect
    what is going on and induce reflection.
  • The new risks change the relation between science
    and society.
  • Paradox we need science and technology to solve
    the problems induced by science and technology.
  • The perception and definition of risks are
    constitutive for politics.
