Title: Skinner's Behaviorism


1
Skinner's Behaviorism
  • I. Behaviorism as a version of Physicalism
  • II. Implications for Education and Government
  • III. Skinner's Theory of Value

2
Three Theories of the Mind
  • Hylomorphism (Aristotle, Aquinas)
  • Dualism (Descartes)
  • Physicalism (Hobbes, Skinner)
  • Eliminationism
  • Reductionism

3
Problems with Reduction 3
  • 3. The problem of multiple realizability.
  • The same mental state could be realized by
    infinitely many different physical states.
  • The same belief can be shared by people whose
    brains are quite different, even by creatures of
    different species.
  • Even -- aliens who are silicon-based, or androids
    with electronic brains.

4
Connection between 1 3
  • This is a characteristic feature of teleological
    states the same end can be achieved by
    infinitely many different means.
  • Screwdrivers can be made of many different
    materials, in many different shapes or forms
    (power vs. manual).
  • More than 30 different kinds of eyes in nature.

5
Problem 4 Qualities of Conscious Experience
  • Consciousness seems to involve certain qualities
    (called qualia, singular quale), like the
    feeling of pain or the appearance of colors, that
    cannot be reduced to physical properties.
  • Possibility of zombies, color-spectrum
    inversions. Undetectable by behavior, interaction
    with environment, brain states.

6
Behaviorism as a Version of Physicalism
  • Early version of physicalism stimulus response
    model.
  • Build a simple, 2-column table
  • inputs in first column, outputs in second.

7
Operant conditioning
  • Includes a kind of "memory" of past experience.
  • Possibility of positive and negative
    reinforcement.
  • X is a positive reinforcement of behavior Y if
    and only if the association of X with Y makes the
    repetition of Y more likely.

8
Human beings are finite automata.
  • Represent by a more complicated table.
  • Rows possible inputs (environmental conditions).
  • Columns possible internal states.
  • In each square, we put two things
  • 1. The output, behavior produced.
  • 2. The new internal state into which the subject
    is transformed.

9
Everything is finite
  • finitely many inputs (conditions to which the
    subject is potentially sensitive)
  • finitely many internal states
  • finitely many possible behaviors.

10
III. Implications of Behaviorism for Education
and Government
  • A. Education -- especially moral, character
    education.
  • Classical (teleological) view there is a
    fundamental distinction between manipulation and
    education.

11
Education (on classical view)
  • Assists and nurtures natural development of moral
    sense, character
  • Goal teachers initiate learners into a state to
    which they have already attained (maturity,
    wisdom).

12
Manipulation (on classical view)
  • Circumvents or overrides natural functions,
    development.
  • Goal to modify students' behavior for the good
    of society, without reference to the current
    state of the teachers.

13
Education vs. Manipulation
  • On the behaviorist view this distinction is
    empty. All so-called education is merely a form
    of manipulation (behavior control).
  • There is no natural development, "no unfolding
    of a pre-determined pattern" (p. 89)

14
Government
  • On classical view, individual liberty is an
    important goal
  • In order to attain happiness, each individual
    needs opportunities to exercise and develop
    virtue practical wisdom.
  • This necessitates a sphere of private sovereignty.

15
Distinction liberty license
  • One has no right to do what is inherently vicious
    -- e.g., to murder, enslave or dominate another.
  • When law prohibits such vicious acts, no liberty
    is lost.

16
Contrast Hobbes Rousseau
  • Held that every law is a restriction of liberty.
  • Perfect liberty is possible only in the state of
    nature (anarchy).

17
Skinner there is no such thing as liberty
  • So, no law, regulation or social control involves
    a loss of "liberty". Liberty is not an
    intelligible social goal.
  • Why not? Skinner denies the existence of choice,
    and of virtue. These are mythical components of
    happiness.

18
Persuasion vs. Manipulation
  • On the classical view, the state is a
    partnership, based on mutual respect, and the use
    of persuasion, not coercion or manipulation.

19
  • Persuasion speech that engages the faculties of
    the rational mind, assisting them to function
    properly in reaching a reasonable conclusion.
  • Manipulation (misuse of rhetoric) speech that
    seeks to circumvent or override the faculties of
    the rational mind (through the exploitation of
    weaknesses and biases), causing them to function
    improperly and form an unreasonable conclusion.

20
Skinners rejection of this contrast
  • Skinner denies the validity of the
    persuasion/manipulation distinction.
  • He denies the existence of such inner faculties,
    and of the distinction of proper/improper
    functioning.

21
Who controls the controllers?
  • Skinner argues that there "should" be reciprocity
    between controllers and controlled, effective
    measures of "counter-conntrol". (p. 169)
  • However, he gives no reason why this should be
    so. Nor does he explain when efforts at
    counter-control are proper and when they are
    merely the result of neurotic attachment to
    "freedom".

22
  • If the controller has the proper goals, why
    shouldn't his power be absolute?
  • Can there be effective countercontrol, when the
    controller is acting benevolently? No rational
    basis for objection. Result the nanny state.
    (Hillaire Belloc, The Servile State).

23
Skinner's Theory of Value
  • Definition
  • Good things are positive reinforcers.
  • A positive reinforcer is a consequence of
    behavior that makes the behavior more likely to
    recur.

24
Relativism
  • Immediate consequence radical relativism.
  • What is good for you may not be good for me.
  • What reinforces us depends not only on genetic
    endowment, but also on "training" by environment.
    Both vary from person to person.

25
Optimism?
  • The best things are those consequences that most
    effectively reinforce behavior.
  • In the long run and for the most part, the most
    effective reinforcers must succeed in
    reinforcing.
  • Consequently, most people behave so as to produce
    the most effective reinforcers.

26
Absurd consequences?
  • This means that most people enjoy the best
    possible life (given Skinner's definition of the
    best).
  • E.g., addicts enjoy the life that is best for
    them, since their behavior is under the control
    of the most powerful reinforcers.

27
  • Ditto for serial killers, who are most
    effectively reinforced by the thrill of violence.
  • Consequence fatalism or quietism. This is
    already the best possible world.

28
Can Skinner respond?
  • We want to say at most that people enjoy the
    best possible life, given their circumstances.
  • But, what reinforces whom is always relative to
    circumstances.
  • So, can Skinner give an account of which
    circumstances are best?

29
Skinner and Survival Value
  • Skinner adopts survival value as the ultimate
    value.
  • The survival of one's "culture".

30
Raises two questions
  • 1. The survival of what exactly?
  • 2. What makes survival of the culture/species an
    especially gripping value, given behaviorism?

31
1. The survival of what?
  • If we modify our culture radically through
    behavior modification our genes through genetic
    engineering, what survives the process?
  • Analogy in Vietnam, "to save the village, we had
    to destroy it."
  • Are we ensuring the survival of our culture, or
    are we ensuring its extinction and replacement?
    Ditto for our species.

32
2. Is survival value especially gripping, given
behaviorism?
  • Apparently not -- depends on what happens to
    reinforce Skinner, due to historical accidents.

33
Possible confusion
  • We might think the following
  • If natural selection is the ultimate cause of
    human morality, then the survival of the species
    (or one's "culture") is the highest moral value.

34
Two problems
  • 1. This depends on a very dubious theory of group
    selection.
  • According to the consensus of biologists, natural
    selection does not favor behavior that benefits
    the whole species at the expense of the
    individual's genes.
  • So, natural selection would not tend to give
    human beings an overriding concern for the
    welfare of the species (or of any other large
    group, like the culture).

35
2. Confuses the relationship between natural
selection and moral values.
  • Any concern for the welfare of humanity is a
    product of a "high" morality (in Darwin's sense),
    which is in turn the by-product of other, more
    fundamental adaptations.
  • But, within the sphere of "high" morality, a
    concern for the welfare of humanity depends on a
    belief that humanity is worthy, deserving of
    survival.

36
From the perspective of morality
  • Mere survival of the species is not the ultimate
    end -- it is merely a means to the perpetuation
    of other values, such as the perpetuation of
    love, dignity, friendship, science, art, etc.

37
The Cognitive Revolution
  • Two scientific challenges to behaviorism
  • Chaos theory
  • Chomskys linguistics

38
Chaos theory
  • The physical attributes of the human body are
    capable of infinite variation vary continuously
    along a spectrum.
  • To represent the body as a finite automaton, we
    must assume that states that vary only slightly
    differ only slightly in their effects.
  • This is true only for linear (non-chaotic)
    systems.

39
  • The body is a non-linear, chaotic system.
  • The Butterfly Effect small, imperceptible
    differences in input can make massive differences
    in output.
  • It's not surprising that it's easier to put a man
    on the moon than to teach a classroom full of
    children to read.

40
Chomsky's linguistics
  • Representing human beings as computers (Turing
    machines), not finite automata.
  • Potentially infinite memories -- idealization.
  • Performance vs. competence.
  • Equivalent to efficient vs. final causation.
  • Competence what the mind is supposed to do.
