Title: Skinner's Behaviorism
1Skinner's Behaviorism
- I. Behaviorism as a version of Physicalism
- II. Implications for Education and Government
- III. Skinner's Theory of Value
2Three Theories of the Mind
- Hylomorphism (Aristotle, Aquinas)
- Dualism (Descartes)
- Physicalism (Hobbes, Skinner)
- Eliminationism
- Reductionism
3Problems 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.
4Connection 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.
5Problem 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.
6Behaviorism 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.
7Operant 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.
8Human 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.
9Everything is finite
- finitely many inputs (conditions to which the
subject is potentially sensitive) - finitely many internal states
- finitely many possible behaviors.
10III. 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.
11Education (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).
12Manipulation (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.
13Education 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)
14Government
- 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.
15Distinction 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.
16Contrast Hobbes Rousseau
- Held that every law is a restriction of liberty.
- Perfect liberty is possible only in the state of
nature (anarchy).
17Skinner 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.
18Persuasion 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.
20Skinners 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.
21Who 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).
23Skinner'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.
24Relativism
- 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.
25Optimism?
- 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.
26Absurd 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.
28Can 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?
29Skinner and Survival Value
- Skinner adopts survival value as the ultimate
value. - The survival of one's "culture".
30Raises two questions
- 1. The survival of what exactly?
- 2. What makes survival of the culture/species an
especially gripping value, given behaviorism?
311. 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.
322. Is survival value especially gripping, given
behaviorism?
- Apparently not -- depends on what happens to
reinforce Skinner, due to historical accidents.
33Possible 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.
34Two 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).
352. 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.
36From 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.
37The Cognitive Revolution
- Two scientific challenges to behaviorism
- Chaos theory
- Chomskys linguistics
38Chaos 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.
40Chomsky'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.
