Thought of the day

Bigots will often argue that homosexuality is a choice. It isn’t, but let’s pretend it is. Then heterosexuality must also be a choice. So what convincing reason do we have to give marital protections to one choice over another? It surely has nothing to do with children. Gay people have kids, too. And besides, we know straight couples over, say, 80 cannot have children, yet no bigots are clamoring to deny them the right to marry. So what other distinctions do we have? Any? Any at all?

3.4 billion year old fossils recently discovered

Martin Brasier of Oxford and his team have just described some very ancient fossils discovered in rocks dated to 3.4 billion years of age. The article is unfortunately behind a paywall, so I am unable to review it, but Jerry Coyne lays out the evidence neatly:

As the authors note, “determining the biogenicity [biological origin] of putative Archaean microfossils is notoriously difficult.” How do we know that these things are real remnants of bacteria and not just inclusions or artifacts? There are several independent lines of evidence, none conclusive but together building a very solid case:

  • They look like cells, being cell-shaped, cell-sized, and forming chains of spheroids that look like chains of both well-established fossil bacteria and modern bacteria. Some can even be seen “dividing” or expelling their contents after cell damage (see figure above).
  • The variation in size of the bodies is small—smaller than you’d expect if they were abiological inclusions. A uniformity of size, however, is expected if they’re all members of one living species.
  • The cell “walls” of the microfossils, too, are of uniform thickness, unlike that of artifacts like silica grains coated with carbon.
  • The geochemistry of the bacteria and surrounding rock supports the idea that these are true organisms. This involves not only the isotopic nature of the carbon, but the presence of nitrogen, a crucial biomarker, within the cell walls.

This reminds me very much of Margulis’ endosymbiotic theory and its multiple lines of evidence. Of course, that idea was a cornerstone achievement of 20th century biology whereas this recent discovery pushes the known origins of life back about 200 million years, but that does not mean it isn’t important. Braiser’s find goes to demonstrate the nature of early bacteria. Many of the features in these fossils show that ancient bacteria operated in ways similar to certain bacteria today – if you find something that works, keep it up. The find also demonstrates that life can come to be quite quickly. Earth is only 4.54 billion years old and probably was not hospitably cool enough for life for its first half billion years. Given this 3.4 billion year date plus the fact that these fossils are fairly complex, it is not a stretch to say life dates back even further, probably quite soon after it was possible for it to do so on Earth.

Finally, I have to reflect Coyne’s curiosity that this was not published in Nature or Science, but rather Nature Geoscience. It’s still in a prestigious enough journal, but the paper is important enough where it deserves publication that comes with a higher profile. I’m sure the authors attempted to reach the best level possible, so who knows what the deal is.

Thought of the day

One of the great accomplishments of the New Atheists has been to tear down the idea that faith is a good thing. Pay attention to anyone involved in religious debates that has become familiar with what atheists have been saying. They do all they can to distance themselves from faith – something the Bible pushes as a good thing. (It’s almost like people cherry-pick what they want to take from their holy books, huh?) This is largely due to the New Atheist emphasis on the need for evidence.

Of course, go to any church with an average congregation that is unfamiliar with these sort of debates and it will not be difficult to find people who still highly value faith. That’s sort of religion’s thing.

Irony much?

I recently made a status update on my Facebook wall which mocked Christianity. As sometimes happened, it soon gathered together a small chorus of people who feel nothing mean should be said about religion. “Why, live and let live, Michael!”, they will say. Of course, then we get faith healing laws in the U.S. and imprisonment of gays in Christian Uganda. For that sort of reason (and more), I think it’s perfectly reasonable to mock religion; it is a hell of a force for evil in the world. (In democratic nations where the populace has been able to rid itself of most of the religious nutbags – our mainstream – life is far, far better on the whole.) I would love to see religion go away.

But out of that status update came a common cowardly Christian. Instead of diving into the discussion, he went to his own wall and made a passive-aggressive response. (In terms of my own status, it was probably for the best. My wall actually fostered (and is still doing so) a pretty good discussion amongst a number of intelligent individuals.) First let me show the comment that spurred the passive-aggressiveness. This was made by a friend of mine:

1.) Respect for beliefs and respect for the people who hold them are often confused with each other. Demanding that we respect each other’s beliefs is silly. I respect my room mate. However, I don’t respect his belief that it’s ok to leave the bread bag open. Similarly, I respect my girlfriend. But I don’t respect her belief in God. To ask someone to respect a belief with which they disagree is essentially asking them to agree with it. The very reason people disagree with something is because they don’t respect it.

2.) Religious beliefs often bring with them the encroachment of others’ rights. It’s the belief of many that gays shouldn’t be able to marry. And you think that deserves respect?

3.) Condoning such wide-scale subscription to superstition is a huge impediment to progress.

That was a response to a variety of points, but the part which caught the attention of the cowardly Christian was number 1. Here is his passive-aggressive status update:

Evidently I’m supposed to tolerate your beliefs but mine are to be mocked.

Rather than explain the rather simple distinctions between toleration, acceptance, and respect of beliefs, I decided to point out that he was being passive-aggressive. If he wants to respond to what he sees on my wall, he should grow a pair and make a post in the proper, adult location. (It’s like all those Christian blogs that make response posts but refuse to link back to the original posts because they come from atheist blogs.) This then turned to another Christian saying I was passive-aggressive. It was a stupid reflection of my rhetoric and it had no basis; people may think what they wish about me, but imagining that I’m passive-aggressive is just silly. I quickly dispelled the notion:

[Name of Second Christian], I think you are a genuinely stupid person who cannot understand the majority of arguments you hear. I think your anti-science bend comes from your quack of a mother, and I sometimes pity your ignorance.

How’s that?

(That person is a creationist and his mother is an alternative ‘medicine’ practitioner.)

Well, you can imagine how that went over. “Why, you, sir, have insulted a person’s mother! That’s just awful!” It’s a silly complaint, really. I insulted her ‘profession’ and used her as a proxy to do so. Since the attack portion of my comment is hardly that specific to her, it’s just people having a knee-jerk reaction. It’s like getting upset over “Yo momma” jokes, except the momma in this case really is a quack.

But I’m used to whines about tone. People who can’t argue their points bring it up as if it’s legitimate. Sometimes it’s because of thin-skin. Most of the time it’s a way to demand respect. If it is off-limits to be disrespectful towards something, whether it be religion or quackery, then it will quickly appear as if that something is worthy of an academic or intellectual discussion. And so whines about tone are aplenty. Of course, that gets boring pretty quickly. Just about the only thing that can make those whines worth reading is when they come with a splash of irony. That happened about 50 comments into the status update with this gem:

Ok ‘michael hawkins’, you dont have to believe anything you dont want to, and im not trying to convince you because frankly, from the things you have said in this entire blog, you should burn in hell because its EXTREMELY disrespectful how you are talking to us.

How Christian.

I imagine if this person recounted the Facebook comments to a friend of hers, it would go something like this. (Let’s call her Suzy.):

Suzy: So yeah, this guy called a person’s mother a quack.

Suzy’s Friend: Whoa! Someone’s mom?

Suzy: Yeah, I couldn’t believe it!

Suzy’s Friend: So what did you say?

Suzy: Oh, I told him to go to hell…out of respect, of course.

Suzy’s Friend: Of course.

(I realize that by not naming names, it may seem as though I am ironically being passive-aggressive. If these comments came from a public page, I would post names. Given that I know this person’s Facebook page is only visible to his friends, it would be wrong for me to say who said what. But worry not, each party involved will get the message.)

The transcendental takedown

I’ve decided that when the fancy strikes me I’m just going to make a post about some argument for the existence of God. I recently did it with the first cause argument (and it was incredibly easy). Today I am going to address the transcendental argument:

The argument proceeds as follows:

1. If there is no god, knowledge is not possible.
2. Knowledge is possible (or some other statement pertaining to logic or morality).
3. Therefore God exists.

This is another easy one. The very first premise is incorrect. Knowledge is simply a description of how accurately we perceive the world around us relative to any verification method. For example, a child has knowledge when his parents tell him the stove is hot. His verification method is his parents. They may be wrong, but that is entirely immaterial – remember, knowledge does not itself mean accuracy, but it is instead a measure of accuracy based upon any verification method. (Naturally, some verification methods will be better than others. For instance, verifying a contention using science will always be superior to verifying something using a holy text since the former case involves rigor whereas the later is merely faith.)

So what we have here is that knowledge is not something which is based upon the existence of any god. It is something which is defined by humans and which describes how we take in and process information. We can go further and look at the evolution of consciousness, but that would be getting into the gritty details, something which is not required in order to defeat the transcendental argument. So let’s rewrite it:

1. If there is no god, that has no bearing on whether or not we have knowledge.
2. Knowledge is possible.
3. Nothing has been said about any god.

University of Westminster gets rid of naturopathy

PZ has a post about quackery at two different universities. One is his own university, and he has a pretty good take down. The other is the University of Westminster where alternative ‘medicine’ degrees have been getting phased out over the years:

At the end of 2006, Westminster was offering 14 different BSc degrees in seven flavours of junk medicine. In October 2008, it was eleven. This year it’s eight, and next year only four degrees in two subjects. Since “Integrated Health” was ‘merged’ with Biological Sciences in May 2010, two of the original courses have been dropped each year. This September there will be a final intake for Nutrition Therapy and Naturopathy. That leaves only two, Chinese Medicine (acupuncture and (Western) Herbal Medicine.

I’m particularly happy about the demise of the courses in naturopathy given my familiarity with that non-science subject, but I’m just as happy about to hear the other programs that are getting shut down. I just wish more American universities and states would start putting bans on the spread of all this malarkey. It’s silly stuff that is based upon magical thinking. It needs to go.

Thought of the day

I bet I’ve had this as a Thought of the day in the past, but it’s still true: There is not a single good argument for the existence of God.

Logic

This is a piece of logic that most believers can’t seem to grasp:

Can we at least agree that this is racist?

I don’t know as there can be much debate on this one:
