Title: Abstraction, Representation and Vygotsky on Scientific Concepts
1Abstraction, Representation and Vygotsky on
Scientific Concepts
- Dr Jan Derry
- Institute of Education, University of London
2Here 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)
3Solution ?
- 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.
4Critique 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.
5Vygotskys 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)
6Philosophical 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.
7Recognition 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
8Failure 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
9Designative 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)
10Wertschs 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
11Vygotsky 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
12Vygotsky 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)
13Logical 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)
14Vygotsky 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)
15Vygotsky 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.
16Sellars 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
17No 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)
18The 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)
19Human 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)
20Normativity 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.
21Brandom 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
22Concepts 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
23Privileging 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.
24Brandom 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)
25Brandom 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
26Meaning 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. - Derry, J. (forthcoming) Abstract Rationality in
