Science and Worldviews: Slate Sees the Light

Slate — yes, stet that, Slate — carries an excellent essay opening up the interesting question of whether political and philosophical presuppositions distort what we think of as mainstream science (“Lab Politics: Most scientists in this country are Democrats. That’s a problem“). Author Daniel Sarewitz notes that among scientists, self-identified Republicans make up a dismal 6 percent, while Democrats are 55 percent (the rest are independents and I-don’t-knows). Though Sarewitz doesn’t mention evolution, he ought to have done so. But never mind. While folks on the political right have been strangely slow to pick up on the political resonances of Darwinism, his illustration from the climate debate makes the same point:

Could it be that disagreements over climate change are essentially political — and that science is just carried along for the ride? For 20 years, evidence about global warming has been directly and explicitly linked to a set of policy responses demanding international governance regimes, large-scale social engineering, and the redistribution of wealth. These are the sort of things that most Democrats welcome, and most Republicans hate. No wonder the Republicans are suspicious of the science.

Think about it: The results of climate science, delivered by scientists who are overwhelmingly Democratic, are used over a period of decades to advance a political agenda that happens to align precisely with the ideological preferences of Democrats. Coincidence — or causation?

Arsenic and Old News

The media has been buzzing about NASA’s claim that scientists that have discovered “life as we do not know it” (MSNBC)–purportedly finding bacteria that can use arsenic instead of phosphorous in its DNA. David Klinghoffer already blogged about this story here, interviewing astronomer Guillermo Gonzalez (who has conducted research on astrobiology) on the find. The public first became aware of this story last week when NASA announced it would be holding a press conference that would reveal “an astrobiology finding that will impact the search for evidence of extraterrestrial life.” NASA’s announcement inspired a chorus of speculative excitement among materialists and UFO true-believers alike, who stated things like: NASA is holding a press conference on Thursday to make an announcement.

Why Doesn’t the NCSE Have an Atheism Project?

Jerry Coyne has an amusing post on the National Center for Science Education’s outreach effort to Christians. Coyne, in a post titled “NSCE Becomes BioLogos,” laments the rigorous efforts of the NCSE’s Faith Project, which is a major outreach program to Christians and other people of faith.

Coyne quotes the NCSE:

The National Center for Science Education (NCSE) is a not-for-profit, membership organization providing information and resources for schools, parents and concerned citizens working to keep evolution in public school science education. We educate the press and public about the scientific, educational, and legal aspects of the creation and evolution controversy, and supply needed information and advice to defend good science education at local, state, and national levels….The National Center for Science Education is not affiliated with any religious organization or belief. We and our members enthusiastically support the right of every individual to hold, practice, and advocate their beliefs, religious or non-religious. Our members range from devout practitioners of several religions to atheists, with many shades of belief in between. What unites them is a conviction that science and the scientific method, and not any particular religious belief, should determine science curriculum.

Coyne asks, perceptively:

Is the Origin of Life in Hot Water?

Is origin of life chemistry in hot water? So it seems according to a new paper in the Proceedings of the National Academy of Sciences. The authors address the conundrum of origin of life chemists between the rate of (un-catalyzed) organic reactions and the lack of time available for these reactions to occur. From the article (note: an enzyme is a biological catalyst):

Whereas enzyme reactions ordinarily occur in a matter of milliseconds, the same reactions proceed with half-lives of hundreds, thousands, or millions of years in the absence of a catalyst. Yet life is believed to have taken hold within the first 25% of Earth’s history. How could cellular chemistry and the enzymes that make life possible, have arisen so quickly?” [Internal citations omitted]

Indeed this is one of the problems with origin of life scenarios, particularly those scenarios that presume a metabolism-first world (as opposed to an RNA-first world). The half-life of certain reactions without a catalyst can be millions of years, but studies show that the emergence of early bacteria could be dated as far back as 3.5 billion years (see ENV post on a cold origin of life and Schopf, J. William, “The First Billion Years: When Did Life Emerge?” Elements vol 2:229 (2006) for more on this). This means there was a limited amount of time for fundamental biological reactions to occur. Reaction kinetics can be prohibitive. However, the authors of this paper have a theory to solve the reaction kinetics problem.

Another Reason to Doubt the Relevance of Jeffrey Shallit

Materialist mathematician Jeffrey Shallit has a post on an article in the Globe and Mail about philosophy and the immateriality of the mind. Shallit’s post is titled “Another Reason to Doubt the Relevance of Philosophy”. Shallit doesn’t think much of philosophy: If philosophers think the view that “The brain is not an organ of consciousness. … The brain has no cognitive powers at all” deserves anything more than a good horselaugh, this simply shows how irrelevant philosophy has become … Our future understanding of cognition will come from neuroscience, not from Wittgenstein. Philosophy is plainly irrelevant to Shallit, which is the problem. Wittgenstein may not inform Dr. Shallit’s understanding of cognition, but Descartes, Kant, Hume, James, Skinner, Block, the Churchlands, Read More ›

Michael Behe’s Quarterly Review of Biology Paper Critiques Richard Lenski’s E. Coli Evolution Experiments

In a previous post, I discussed Michael Behe’s recent paper in Quarterly Review of Biology, “Experimental Evolution, Loss-of-Function Mutations and ‘The First Rule of Adaptive Evolution’,” which reviews much recent work in the field of bacterial evolution. He devotes particular space, however, to the research of Richard Lenski, who has now grown over 50,000 generations of E coli in the lab to study its evolution. Lenski’s work was cited by Richard Dawkins most recent book (The Greatest Show on Earth) as the ultimate refutation of irreducible complexity. Dawkins’ book, however, made a straw man argument by discussing a misguided attack on Lenski’s work by Conservapedia editor Andrew Schalfly, completely ignoring critiques of Lenski’s research by Behe in The Edge of Read More ›

My Question for P.Z. Myers: What Endows a Human Being With the Right to Life?

P.Z. Myers has responded to my post about his views on abortion and personhood. In reply, Myers posted pictures of a zygote, an embryo, and a group of young women. He asserted that differences in appearance between these human beings was an ethical basis for denial of the right to life to humans in utero.

I take it for granted that Myers, being a competent biologist, agrees with me on this point: a living human embryo/fetus is a member of the species Homo sapiens (it is no other species). That is, a distinct human life begins at conception and ends at natural death. That is not to to say that Myers and I agree on rights, personhood, etc., but merely to say that a human life is a continuum that begins at conception. That is a fact of biology.

Myers makes the bizarre assertion that devaluing some human beings adds value to the life of others:

Huh. I don’t know about you, but to me, that [recognizing that humans in utero have a right to life] doesn’t exalt human life at all — it seems to do the opposite, and devalue the life of women.[my ellipsis]

Every stage of human life is…human life. Each young woman in Myer’s picture looked like a “blob of cells” when she was an embryo. An embryo is what a human being looks like 20 days after conception. A young adult is what a human being looks like 20 years after conception. An elderly adult is what a human being looks like 80 years after conception. All are human beings of different ages. Of course, abilities, appearance, etc. differ radically, but a human being is a human being. And all human beings have a right to life. To respect and value one human being despite his/her immaturity is not to denigrate a mature human being. Respect for life protects and respects all human beings.
