On the alleged need to define one’s terms

Vilayanur Ramachandran described the alleged need to define one's terms carefully by telling the following story:

After his triumph with heredity, [Francis] Crick turned to what he called the "second great riddle" in biology—consciousness. There were many skeptics. I remember a seminar he was giving on consciousness at the Salk Institute here in La Jolla. He'd barely started when a gentleman in attendance raised a hand and said, "But Doctor Crick, you haven't even bothered to define the word consciousness before embarking on this." Crick's response was memorable: "I'd remind you that there was never a time in the history of biology when a bunch of us sat around the table and said, 'Let's first define what we mean by life.' We just went out there and discovered what it was—a double helix. We leave matters of semantic hygiene to you philosophers."

Does the bible really prohibit gay marriage?

Does the bible prohibit gay marriage, or are conservative Christians again up to their favorite trick, cherry-picking? The following excerpt from The Miami Herald suggests that cherries are being picked in earnest.

[Matthew] Vines is a Christian, a 22-year-old Harvard undergrad raised in a conservative evangelical church in Kansas. He is also gay and says he grew up being taught that the Bible condemns his sexual orientation. He took two years off from school to research and study whether or not that assertion is true. The result is The Gay Debate: The Bible and Homosexuality. It’s a video. . . Vines’ speech is a masterwork of scriptural exegesis and a marvel of patient logic, slicing and dicing with surgical precision the claim that homophobia is God ordained. So effective is the video that after viewing it, Sandra Delemares a Christian blogger from the United Kingdom who had, for years, spoken in staunch opposition to same sex marriage, wrote that it “revolutionised” her thinking. Vines points out, for instance, that the frequently quoted condemnation (homosexuality is an “abomination”) from the Old Testament lawbook of Leviticus has no application to Christians, who are bound by the teachings of the New Testament. He explains that St. Paul’s admonitions about the “effeminate” and “abusers of themselves with mankind” stem from modern mis-translations of ancient Greek terminology.
With that as an introduction, here is the video featuring Matthew Vines: This is an impressive presentation. At the 16 minute mark, Matthew begins to examine the six bible passages that supposedly condemn homosexuality. None of them survive his scrutiny.

Obama campaign demolishes mostly false Romney ad

Here's a different way to respond to false accusations: Set up your spokesperson to look like a news reporter and state the facts, as confirmed by Politifact. In other words, cut the ominous (or patriotic) music, stare into the camera and treat viewers like adults: Anyone who visits Dangerous Intersection knows that I have serious reservations about Barack Obama (e.g., see here), but this Romney ad is full of provable lies. For conservatives, getting Barack Obama out of office has become a sacred quest, which translates to the means justifies the end. It is quite predictable that Democrats will have their own buckets of falsehoods. All of this brings to mind Jonathan Haidt's admonition that morality "binds and blinds." And see Haidt's discussion with Bill Moyers here.

Modern evolution of human animals

Do human animals continue to evolve? The evidence is clear that we do, for instance in the case of that small subset of human adults who drink milk, according to this article in Discover Magazine:

Assertion: Because modern humans are a young species, there has not been enough time for major differences to emerge between populations. This is false. 5 to 10 thousand years ago a set of strangely mutated humans arose. They continued to be able to digest lactose sugar as adults, in contravention of the mammalian norm. In fact, humans are the only mammals where many adults continue to be able to consume milk sugar as adults. The rapidity of this shift has been incredible. 5,000 years ago almost everyone in Scandinavia was lactose intolerant. Today, very few are. The area of the European genome responsible for this shift is strikingly homogeneous, as a giant DNA fragment “swept” through populations in a few dozen generations. The literature on recent human evolution is still evolving, so to speak. But it is clear that during the Holocene, the last 10,000 years, our species has been subject to a wide array of selective forces. Lactose tolerance, malaria tolerance, differences in color, hair form, and size, seem to be due to recent adaptations. And because of different selection pressures human populations will evolve, change, and diversify. Our African ancestors left 50 to 100 thousand years ago. If 10,000 years was enough time for a great deal of evolution, then the “Out of Africa” event was long enough ago to result in genetic diversification, which we see around us.

Zach Wahls honors his two moms.

Today, an attorney with whom I work told me I absolutely needed to drop what I was doing in order to listen to a 19-year old man giving a statement to the Iowa legislature. Under consideration was a constitutional amendment that would reverse the landmark case of Varnum v Brien. I looked up Zach Wahls on Youtube and watched his incredible speech. My friend then told me that Zach also happened to be in town, at Left Bank Books, 5 blocks away from my law office. I walked over, arriving in time to hear Zach ending his prepared remarks, and opening the floor to questions. One of the main points he made is that people react badly to households of two gay parents because they have a "fear of the unknown."
