Although it was definitely not on today's lesson plan, I was happy to let the discussion that began with the question of whether or not parents should be allowed to choose the sex of their children run on for a bit because you conducted it extremely well: serious ideas about which there was very strong disagreement were presented, supporting and opposing ideas and facts were presented and taken seriously by all sides, and people refined and modified their opinions as evidence and reasons were presented.
As you will see in Hartmann's first reading in chapter 3 of
Quest, criticism is an important part of the academic study of art. And when we come to read "Looking at Art: What's the Story?" next week, we might extend Hartmann's suggested definition of what characterizes criticism (2007, p. 73). In some of the responses that you wrote this in class earlier today, some of you did, in fact, go beyond the simple two part definition that Hartmann offers us.
Academic discussion, even in respected journals, is often also heated. This is because people care very much about the issues, about what is true and what is to be done, but even a heated academic discussion does not (usually) collapse into a shouting match, although academics, being only human, do sometimes shout, and worse. During this morning's discussion, I was reminded of a debate in 1946 between two of the greatest philosophers of the last century: Karl Popper, whose work continues to exert enormous influence on how we think about science, and Ludwig Wittgenstein, who did work on logic, language and philosophy of mind. In their friendly (!) debate at the Cambridge University Moral Sciences Club (what better place) among other greats such as logician and philosopher of mathematics Bertrand Russell, Wittgenstein is reported to have threatened to beat Popper with an iron fire-poker that was conveniently at hand in the chilly English weather. They behaved a bit better in the journals, where the same argument was carried on with equal passion but less iron waving.
Getting back to the topics this morning, I'd like to discuss the drug question first because I think it's the easier one. As Grace rightly pointed out, if I claim that legalising all drugs will not increase drug use or addiction rates, I have to support that opinion, and because it's a factual claim, argument alone is not good enough: an opinion about the way the world really is must be supported with relevant facts. I agree that it sounds very plausible, that it is very easy to believe, that legalising drugs must lead to an increase in drug use and addiction rates, but being easy to believe does not make any claim about the world true. Many ideas that seem obviously true are false. Aristotle, and every one after him for more than 1,000 years, believed that heavier objects must naturally fall faster than lighter objects; they were all wrong. Unfortunately, this became part of Christian belief supported by the Catholic popes who tortured, killed and threatened anyone who said otherwise, such as Galileo. This legally enforced censorship did not help the misunderstanding to be corrected; on the contrary, as such censorship always does, it guaranteed ignorance and worthless opinion on the topics where free speech was strictly forbidden.
Chieko then helped by pointing out that the relevant facts to consider to determine what effects legalising and criminalising drugs have is to look at examples where some drug has been legalised or criminalised, specifically, at the situation before compared with the situation after. First, the US experience with alcohol prohibition provides a good example of what happens when a popular drug of recreation that is legal is made illegal. As Jeffrey Miron shows in "The Effect of Alcohol Prohibition on Alcohol Consumption" making this drug illegal "had virtually no effect on alcohol consumption" (1999, p. 1). To see the results of legalising all drugs on drug use, and also related health, crime and social issues, Glenn Greenwald provides a solid collection of official statistics on the consequences of decriminalising all drug in Portugal in 2001. As Greenwald emphasises in his executive summary, "none of the nightmare scenarios touted by preenactment decriminalization opponents—from rampant increases in drug usage among the young to the transformation of Lisbon into a haven for 'drug tourists'—has occurred" (2009, p. 1). In other words, everyone's worst fears of what might happen if all drugs were suddenly legalised were proved completely wrong by the resulting facts. The impressive results for Portugal are also stated more briefly in the report and headline of the Forbes business newspaper's article by Erik Kain: "Ten Years After Decriminalisation, Drug Abuse Down by Half in Portugal" (2011). Although the longer and more solidly researched academic paper by Greenwald is a bit more persuasive for me, we don't expect conservative, business publications to publish such things without good reason. You might also find it instructive to Google the effects of decriminalising marijuana use in the Netherlands.
Finally, the question that started the very academic discussion that was not on my lesson plan: Should parents be allowed to determine the sex of their children? In my level 5 class, I give students a choice of essay topics for our major writing assignment, and one of the questions is on the topic of abortion; however, I've written the question very carefully to completely avoid the moral issues. Similarly, in the discussion legalising drugs, I generally avoid the moral questions and focus on the factual, practical issue of what is most likely to be an effective and successful police to solve the serious drug problems that affect many societies. The reason for this is that although I think the moral arguments are even stronger than the practical arguments, those arguments are also much more complex, so I try to avoid them in class until level 6 and higher. It's better to practise on easier topics first and move on to the more challenging ones. I would probably not have given a level 3 or 4 class an explicitly moral question like the one you were arguing, preferring to stick with something a bit narrower and more easily resolved. I might, for example, have asked: Would it be beneficial or harmful for a society to allow parents to choose the sex of their children? This question is interesting and challenging, but I think less difficult than the explicitly moral one.
In class, Frank and I disagreed about the facts in China. Frank, sensibly and rightly, wants me to provide some evidence for my belief. As I said in class, since the statistics I was relying on were ten years old, it was certainly possible that the situation had changed since I last did some research. However, when I checked this afternoon, it appears from their study published in the British Medical Journal by academics Wei Xing Zhu and Li Lu from Chinese universities, and Therese Hesketh at University college London that sex selective abortion has continued to become increasingly common in China at least until 2005, as shown by the wildly skewed ratio of male to female births (Zhu, Lu & Hesketh, 2009). I could not find any reliable study suggesting that this trend might have changed in the years since 2005. It appears that, despite being illegal, sex selective abortion of females has been commonly practised throughout China, although less in urban areas than rural, since the determination of the sex of the foetus became medically possible.
