I recently saw a video of Senator
Bernie Sanders grilling Scott Pruitt, President Donald Trump’s nominee for the
post of director of the Environmental Protection Agency. Throughout his seven
minutes Sanders repeatedly demanded that Pruitt affirm that 97% of scientists
believe that global warming is a grave threat to the planet; that it is caused
by human activity; and that the government must take steps to shut down the use
of fossil fuels. Of course, Sanders jumped in and interrupted every attempt by
Pruitt to answer his questions. He ended by saying that he could not vote to
confirm him, as if there was ever any doubt.
To be fair I must say that Sanders
qualified his question by adding that the 97% figure referred to the percentage
of peer-reviewed papers that had appeared in climate change journals and other similar
publications. I think that this qualifier is overlooked when most people
consider the question of scholarly or scientific consensus. I can certainly
believe that 97% of these peer-reviewed papers support the human responsibility
for global warming. What is hard to believe is that 3% of the papers were able
to sneak their way through the peer-review process and cast doubt on the
hypothesis.
My own experience makes me
skeptical about the whole peer-review process. For years I have subscribed to a
couple of scholarly journals on the Renaissance. Inevitably, they feature
articles or book reviews on Shakespeare. Never have I seen one that would even hint
that the great plays and poems might have been written by a man of much greater
education and life experience than the man from Stratford on Avon.
Great writers like Mark Twain,
Walt Whitman, and Henry James raised the question in the nineteenth century.
Sigmund Freud shared the view that someone else was the author as did
Shakespearean actors like Orson Welles and Derek Jacobi. Dozens of books on the
authorship question have appeared in the past few years but most go unmentioned
in the peer-reviewed journals.
My own experience in the field of
Renaissance art history has also made me question the peer-review process. In
the past dozen years, I have been able to arrive at plausible interpretations
of some of the most well-known but most mysterious paintings of the Renaissance.
I have done the research, written up my findings but found that the peer-review
process is a closed shop, only open to peers. Necessity made me turn to the web
and in 2010 I put my interpretations on a website and also created a blog, Giorgione et al..., to
explore the subject further.
Scholars often urge their students
to “think outside the box” but rarely follow their own advice. Although their
politics may be liberal and even radical, they tend to be conservative when it
comes to their own subject. Graduate students have to be aware of the danger of
criticizing their mentors. Professors must still publish to keep their jobs,
advance their careers, or gain grant monies. It is very difficult to challenge
the traditional wisdom or orthodoxy. As one
art historian wrote,
“To do so would be to question the competence of most of those who have written on the subject, and this is something that no one…wants to do…the longer those views have gone unchallenged the greater the authority that they have acquired.”
Galileo is a hero to so-called “freethinkers”
but in his time, he stood virtually alone against all the professional
scientists and mathematicians of his time who dominated the institutions of
higher learning. He used a primitive telescope to destroy the elaborate system accepted
by more that 97% of the leading experts. Oddly enough, a few Jesuit astronomers
were among his few early supporters.
Climate change has become like a
new religion and its priests can be found in the scientific establishment.
Their devoted followers march in street processions to proclaim their beliefs
and attack heretics. For them the issue is settled and no further debate is
necessary. What are they and Bernie Sanders afraid of? Why did he find it
necessary to interrupt and ignore any attempt on the part of Scott Pruitt to
reply?
