Title: Abstraction, Representation and Vygotsky on Scientific Concepts


1
Abstraction, Representation and Vygotsky on
Scientific Concepts
  • Dr Jan Derry
  • Institute of Education, University of London

2
Here is a problem
  • A rope is tied around the Earths equator.
    Then a ten-meter-long piece is added to it and
    the rope is pulled evenly so that everywhere the
    distance between the Earths rope and the surface
    is the same? The question is Would this distance
    be sufficient for a cat to sneak under the rope?
    (Kozulin, 1998, Psychological Tools)

3
Solution ?
  • Imagine the additional length added in one place
    (a loop of about 5m high) and then being spread
    out to extend the full length of the rope,
    resulting in a minute gap too small for the cat
    to fit under.
  • The use of scientific concepts of pi and radius,
    would have yielded the correct but counter
    intuitive answer of a 1.6m gap.

Critique of the privileged status of abstract
rationality - Wertsch
  • Inadequacies of a curriculum that fails to engage
    with the variety of ways that learners make
    meaning
  • Decontextualised rationality - reason that
    extends beyond context and operates with a
    universal notion of truth
  • Move towards the contextual, the situated and the
    practical and away from any notion of reason
    understood in universal terms presupposing a
    shared psychic unity of human kind.

5
Vygotskys commitment to Enlightenment (Abstract)
Rationality
  • Ambivalence in Vygotskys approach to meaning
    both emphasising locale and culture yet also a
    hard scientific realism and a hierarchical form
    of reason
  • demands of rationality impose on philosophy a
    need to seek out abstract, general ideas and
    principles, by which particulars can be connected
    together (Toulmin, 1992 Cosmopolis)
  • abstract axioms were in, concrete diversity was
    out (Wertsch citing Toulmin)

6
Philosophical underpinnings of Vygotskys work
  • Influence of Hegel and Spinoza provide a richer
    idea of rationality and epistemology than that
    contained in prevalent misrepresentations
  • Hegel was the first thinker to appreciate the
    social character of knowledge and it is the
    proper characterisation of knowledge which is at
    stake here.

7
Recognition of Hegels work
  • The influence of Hegels Phenomenology on John
    McDowell and Robert Brandom has been crucial for
    rethinking problems that have arisen out of
    analytic philosophy including the relation of
    language to the world

8
Failure of Schooling to Engage With the Variety
of Meaning-makers
  • Privileging of decontextualised rationality
    (universal, abstract)
  • Language meaning is viewed as a matter of
    referential relationships between signs and
    objects
  • Wertsch

9
Designative Approach Language Represents an
Independent Reality
  • We could explain a sign or word having
    meaning by pointing to what it designates, in a
    broad sense, that is, what it can be used to
    refer to in the world, and what it can be used to
    say about that thing. we give the meaning of a
    sign or a word by pointing to the thing or
    relations that they can be used to talk about

  • (Taylor cited in Wertsch, J. 2000)

10
Wertschs criticism of Vygotsky
  • designative approach consistent with Vygotskys
    account of meaning in scientific concepts
  • Assumption that language and meaning are
    basically concerned with referential
    relationships between signs and objects
  • Assumption that the development of meaning is a
    matter of increasing generalisation and
    abstraction

11
Vygotsky Concepts as generalisations?
  • Takes issue with a conception which sees thought
    as occupying a representational or simple
    referential relation to the world
  • Argues that the idea of general representations
    is inadequate to express what a concept is in
    thinking

12
Vygotsky system of judgements
  • According to our hypothesis, we must seek the
    psychological equivalent of the concept not in
    general representations, not in absolute
    perceptions and orthoscopic diagrams, not even in
    concrete verbal images that replace the general
    representations we must seek it in a system of
    judgements in which the concept is disclosed.
  • (Vygotsky, 1998)

13
Logical thought or richness and diversity?
  • It is completely clear that if the process of
    generalizing is considered as a direct result of
    abstraction of traits, then we will inevitably
    come to the conclusion that thinking in concepts
    is removed from reality. Others have said that
    concepts arise in the process of castrating
    reality. Concrete, diverse phenomena must lose
    their traits one after the other in order that a
    concept might be formed. Actually what arises is
    a dry and empty abstraction in which the diverse,
    full-blooded reality is impoverished by logical
    thought.
  • (Vygotsky, 1998)

14
Vygotsky on concepts
  • A real concept is an image of an objective thing
    in all its complexity. Only when we recognise the
    thing in all its connections and relations, only
    when this diversity is synthesised in a word, in
    an integral image through a multitude of
    determinations do we develop a concept. (
    includes not only the general, but also the
    individual and particular)

15
Vygotsky on concepts
  • In contrast to direct knowledge of an object, a
    concept is filled with definitions of the object
    it is the result of rational processing of our
    existence and it is mediated knowledge of the
    object. To think of some object with the help of
    a concept means to include the given object in a
    complex system of mediating connection and
    relations disclosed in determinations of the
    concept.

16
Sellars Critique of Traditional Empiricism (the
Myth of the Given)
  • In characterising an episode or a state as
    that of knowing, we are not giving a description
    of that episode or state we are placing it in
    the space of reasons, of justifying and being
    able to justify what one says

17
No Outer Boundary to the Conceptual
  • Sellars here speaks of knowledge in particular,
    that is just to stress one application of the
    thought that a normative context is necessary for
    the idea of being in touch with the world at all,
    whether knowledgeably or not
  • (McDowell, 1996, Mind and World)

18
The Unboundedness of the Conceptual
  • The relevant conceptual capacities are drawn on,
    in receptivityit is not that they are exercised
    on an extra-conceptual deliverance of receptivity
  • We should understandexperiential intake not as
    bare getting of an extra-conceptual given, but a
    kind of occurrence or state that already has
    conceptual content
  • Thought can bear on empirical reality only
    because to be a thinker at all is to be at home
    in the space of reasons
  • (McDowell, 1996, Mind and World)

19
Human Animals Acquire a Second Nature
  • Human beingsare born mere animals, and they are
    transformed into thinkers and intentional agents
    in the course of coming to maturity
  • Bildung in being initiated into a language, a
    human being is introduced to something that
    already embodies rational linkages between
    concepts constitutive of the layout of the space
    of reasons
    (McDowell)

20
Normativity and Sociogenesis of Mind
  • To be in touch with the world at all (as a human)
    assumes a normative context.
  • If we want to comprehend our mental powers we
    must understand the nature of normativity
    (Bakhurst)
  • Where a word is used in a seemingly
    non-conceptual way, where the user has no
    conscious awareness of the reasons involved, the
    reasons are still present.

21
Brandom causes or reasons
  • An alarm alerting us to a fire
  • A child shouting fire
  • responding differentially versus perceiving
    or knowing
  • Making a report as a human being is not merely to
    respond differentially it involves inferring
    rather than merely referring, since even non
    inferential reports must be inferentially
    articulated

22
Concepts and Reference - Brandom
  • even noninferential reports must be
    inferentially articulated. Without that
    requirement we cannot tell the difference between
    noninferential reporters and automatic machinery
    such as thermostats and photocells, which also
    have reliable dispositions to respond
    differentially to stimuli.

  • R. Brandom, 2000

23
Privileging Inference Over Reference - Brandom
  • Approaches the contents of conceptually explicit
    propositions or principles from the direction of
    what is implicit in practices of using
    expressions and acquiring or deploying beliefs
  • Understands conceptual objectivity in the context
    of a social practice account of the norms
    implicit in concept use.

24
Brandom on concepts
  • to have conceptual content is just for it a
    concept to play a role in the inferential game
    of making claims and giving and asking for
    reasons. To grasp or understand such a concept is
    to have practical mastery over the inferences it
    is involved into know, in the practical sense of
    being able to distinguish, what follows from the
    applicability of a concept, and what it follows
    from.
  • (Brandom 1994)

25
Brandom Vygotsky on Concepts
  • In order to master any concept, one must master
    many concepts. Brandom, 2000
  • We must seek the psychological equivalent of the
    concept not in general representationswe must
    seek it in the system of judgements in which the
    concept is disclosed. Vygotsky, 1998

26
Meaning designative or inferential?
  • In poor teaching practice words are understood
    solely to take their meaning from the things they
    represent, and it is assumed that it is through
    awareness of this connection that learning occurs
  • The absence of an appreciation that there is an
    alternative to this approach to meaning (one
    which incorporates designation but only as
    secondary to the inferences that are the
    historical genesis of its meaning) can lead to a
    damaging relativism where the need to articulate
    the nature of knowledge is ignored.
