The main title of Clive Wynne’s essay poses the
question: "What are animals?" My initial thought was that the second
part of the title, "Why anthropomorphism is still not a scientific
approach to behavior," should be the sole title, since a screed against
anthropomorphism seems the main point of the paper. But, upon further
reflection I now see that Wynne is questioning what type of animals we
are, what kinds of behavior and underlying processes we share with other
creatures, and how we should go about finding out about these
similarities. Good questions, uncritical answers.
The first part of Wynne’s essay reviews the history
of anthropomorphism in interpreting animal behavior. Although useful,
there is little new here. The main focus of the essay is a critique of
Frans de Waal’s, Marc Bekoff’s, and my own versions of what Wynne
considers current, but still illegitimate anthropomorphism that should
be eliminated from the study of behavior. As a primary target of the
essay, I will expand upon my earlier brief, and apparently unsuccessful,
attempt to clarify my position (Burghardt, 2004). Wynne’s arguments,
once a rallying cry against anthropomorphism, are ineffective against
modern views that acknowledges both that science is a human endeavor and
that we are human animals.
To reduce misstatements I will use direct quotations
freely, beginning with the first page of Wynne’s article:
Though there are differences between these
approaches [Burghardt, Bekoff, de Waal], they share the belief that
projecting oneself into the situation of a member of another species
can lead to the production of useful hypotheses for further
scientific study.
This is a fair, though incomplete, characterization.
But Wynne continues:
. . . anthropomorphism, even of the reformed
varieties, should have no place in an objective science of
comparative psychology . . . because anthropomorphism is a form of
mentalism, and as such is not amenable to objective study. Labelling
animal behaviors with everyday terms from lay psychology does not
explain anything. Rather it is an example of the nominalist fallacy
– the belief that naming something explains it.
Notice that Wynne goes from a claim for a heuristic
method to develop testable hypotheses to a claim that anthropomorphism
is incompatible with objectivity. The clear implication is that there is
no value in the scientific testing of the hypotheses generated by the
anthropomorphic stance. Wynne mainly emphasizes two points:
Anthropomorphism, however qualified, is beyond redemption as a word, for
it is irredeemably mentalistic, and mental processes are incapable of
being studied scientifically. I think that he is wrong. There is a large
literature in opposition to Wynne’s version of the objective-subjective
dichotomy in modern cognitive science, neuroscience, philosophy, and
even behaviorism (such as the writings of Skinner on the study of
‘private events’ or private experience; c.f., Burghardt, 1997). Wynne
also seems to deny that anthropomorphism, the attribution of human type
traits to nonhuman entities, can itself be studied. There exists
fascinating research on how and what traits people attribute to other
species and even neurological studies (Heberlein & Adolphs, 2004) on the
brain mechanisms involved.
Wynne reminds us that naming something does not
explain it. This is true: Naming something as instinct, learned,
genetic, even as a conditioned stimulus, does not explain anything and
neither does calling a response anger, fear, guilt, or remorse. Even
labeling something as food, a predator, a mate or even a reinforcer also
only sets the stage for further analysis. Wynne does not give one
example of my using a term from lay psychology, let alone one that
commits the nominalist fallacy. But then Wynne seems to fall into the
nominalist fallacy himself by suggesting that labeling anthropomorphism
mentalistic explains, as well as dismisses, it! By the end of the essay,
Wynne has suggested that describing an anthropomorphic concept of
remorse in his dog as perhaps a conditioned response, without any data,
explains canine remorse. He wants us to return to the time when a few
basic learning processes were thought to explain the most complex
behavior of animals and all this without formal study or testing of
these alternatives. Wynne is emulating B.F. Skinner who, in an
influential paper, gave a long, detailed explanation of the behavior of
honeyguides (small birds that lead larger animals to resources they can
later exploit) without data, except a few second hand anecdotes
(Skinner, 1966). Plausibility was enough, so why go to the field and
actually learn something about the species? Should Wynne not actually
set up some canine experiments based on his pet observations? The
ethological revolution was about taking animals and their natural
behavior seriously, which meant dealing with diverse species and not
armchair post hoc explanations (in Skinner’s case, to explain
instinct). After more than 40 years, I expected better arguments.
So what did I really try to do? Griffin’s writings on
cognitive ethology reinstated an explicit concern for the experiences
and inner processes accompanying behavior, arguing that classical
behaviorism too often restricted our analysis of complex behavior by its
limited conceptual and methodological scope. He pointed out that the
complex behavior and decisions seen in many animals strongly suggested
some mental experiences comparable, though not identical, to those of
humans, and such an assumption was evolutionarily parsimonious. He
raised the issues of awareness and consciousness in animals, now a most
thriving endeavor among neuroscientists (e.g., Baars, 2005). I was
fortunate to have worked at Rockefeller University with Griffin the year
his book appeared (1976-77). During my stay, I realized that he had not
adequately examined the earlier 19th century movements to understand the
animal mind and why they petered out. Thus, my 1985 paper (Burghardt,
1985) was a critique of the kinds of mentalism and anthropomorphism
Wynne rightly opposes. But I also wanted to show that using our stance
as a sentient being was valuable, if not essential, to the study of
behavior, and many innovative scientists had realized this. I developed
the concept of "critical anthropomorphism" to recognize the multiplicity
of information needed for an effective science of comparative
psychology. We need to use all our scientific and natural history
knowledge about a species, including its physiology, ecology, and
sensory abilities to develop testable hypotheses, which may indeed be
based on ‘hmm, what would I do if I were in a similar situation to the
other species?’
Wynne considers Timberlake’s "animal centered"
theromorphism "a viable step forward" as compared to critical
anthropomorphism. I challenge Wynne to find an essential difference
between us on this point. The real culprit is anthropocentrism. My
chapter on critical anthropomorphism, cited by Wynne, opened with a 1909
quotation by Jacob von Uexküll (Burghardt, 1991, p. 53): "Our
anthropocentric way of looking at things must retreat further and
further, and the standpoint of the animal must be the only decisive
one." It is only through a critical anthropomorphism, I believe, that we
can reach the point of escaping anthropocentrism. Wynne tells us nothing
about how to reach the theromorphic stage.
Not only is critical anthropomorphism useful in
developing hypotheses, an unreflective objectivism is bad science: in
this case anthropomorphism by omission, an idea developed in another
essay cited by Wynne but misrepresented (Rivas & Burghardt, 2002). By
dismissing our own status as animals evolved to deal with the problems
of living that other species also have to face, and attempting to be
completely objective, we fall into serious errors as readily as through
being naively anthropomorphic. In our essay we discuss examples such as
foraging in snakes, aposematic coloration, courtship in Drosophila,
cats hunting mice, language, zoo exhibits, and conservation planning
where scientists were too anthropocentrically objective to do the
careful thinking that would have avoided premature or erroneous
conclusions. Wynne addressed none of these examples; a refutation of
them would have been evidence of the errors of the Rivas and Burghardt
analysis. We write (Rivas & Burghardt, 2002, pp. 10-11):
Anthropomorphism by omission is the failure to
consider that other animals have a different world than ours. We
can, without realizing it, attribute human traits to other species
by failing to consider that many species perceive the world in a
different manner than do we. . . . An important component of this
approach, though often understated, is to consider the animal being
studied as an active participant, with the researcher trying to put
him or herself in the animal’s situation. Timberlake and Delameter
proposed that to understand the behavior of an animal,
"Experimenters not only need to put themselves in the subject’s
shoes, they need to wear them – walk, watch, hear, and act like the
subject" (Timberlake and Delamater, 1991, p. 39).
Furthermore, we pointed out that (Rivas & Burghardt,
2002, p. 15):
It is not enough to avoid an anthropomorphic
vocabulary and claim to be strictly objective. Anthropomorphism is
like Satan in the Bible – it comes in many guises and can catch you
unawares! Lockwood (1989) pointed out some of the guises. The most
easily recognized are not the problem; the conceit that one is
immune to them is more often the problem. . . . scientists are not
immune; lurking unseen it can compromise efforts in many areas. By
using critical anthropomorphism and wearing the animals’ "shoes" we
can overcome part of our natural bias and obtain a more legitimate
understanding of other species . . .
Wynne neither effectively challenges the view that
critical anthropomorphism or its variants produces useful testable
hypotheses nor counters the argument that its neglect is a dangerous
anthropocentrism that has led to erroneous science and conclusions, by
unwittingly assuming that man is the measure of all things. In fact, his
discussion of canine remorse is critically anthropomorphic, since
he not only suggests processes that can be tested, but begins with the
putative similarity between human and canine behavior. I ended my 1991
paper with a series of eight conclusions, and this was the final one:
Reductionistic methods are critical for testing
and evaluating ideas, but the history of animal behavior has shown
that the most paradigm-shaking insights have come about by refusing
to be bound by the accepted mechanistic views of the day. Thus the
ultimate paradox too rarely appreciated. We must be open to new
phenomena considered improbable by current scientific wisdom, yet
use all we know of current rigorous scientific methods to test these
seemingly unlikely possibilities. Critical anthropomorphism provides
a way to combine our human characteristics and abilities with
various kinds of knowledge and keep the question-asking in bounds
but still creative" (Burghardt, 1991, pp. 86-87).
Finally, it is simply wrong to claim that critical
anthropomorphism is mentalism and that all mentalism is based on
non-material (supernatural) causes. Darwin makes clear in his notebooks
that he was a thoroughgoing materialist, and Griffin and other
scientists make similar statements. Methodology should not be confused
with metaphysics or the study of mental processes with the ghost in the
machine. The deeper question is why Wynne continues his single-minded
quest. I certainly cautioned against wooly thinking in 1985 (p. 916),
quoting Ernest Hilgard in my epilogue:
Opening the doors to a freer exploration of
mental activities, although a virtue to those who are disciplined to
scientific procedures and values, may turn into a vice for those who
see the new freedom as an opportunity for free-floating uncritical
fantasies about mental life.
Contrary to Wynne’s strong intimations, I do not
think I have attempted to foster bad science or been unaware of the
dangers of the techniques I have advocated. Instead, it is time to take
on real targets—critiquing the science done and the explanations
offered, not the way the hypotheses were generated.
