Damn, now that song is going through my head. Who was that? Butch says it was Wild Cherry, but don’t hold me to it. Anyway, my friend Eric sent me a link to Michael Shermer’s site, to a page titled Miracle on Probability Street. He wrote it in 2004 but I thought I’d share it with you because it’s very good information.

We’ve all experienced a highly improbable event in our lives. Probably many, in fact. Some of us more than others, some more seemingly improbable than others. There is such a thing as the Law of Large Numbers that explains these coincidences and “miracles”.

The Law of Large Numbers simply stated (sans math): with a large enough sample many odd coincidences are likely to happen.

Coincidence: an occasion when two or more similar things happen at the same time, especially in a way that is unlikely and surprising.

Miracle: an unusual and mysterious event that is thought to have been caused by a god, or any very surprising and unexpected event.

On a side note, I was disappointed with Dictionary.com’s listing on these words so I thought I’d go to the Cambridge Dictionary. The definition above is from the Dictionary of British English. Out of curiosity, I looked up the word miracle in the Cambridge Dictionary of American English:

Miracle: an unusual and mysterious event that is thought to have been caused by God, or any surprising and unexpected event.

A very subtle but telling difference! I think I’ll be using the British version from now on. Read the rest of this entry »

I need your help. I’m going to church soon with my Religion of the Month Club (a subgroup of Morgantown Atheists) and I have the idea of putting an envelope in the collection plate when it comes around. In the envelope I want a few really AWESOME quotes from brilliant people. Preferably not nasty, but very smart. I am asking for your suggestions! Which reason/atheism/brilliant/freethinker quotes should I put in the envelope?

The other day I wrote about Critical Thinking and how important it is. But knowing it’s good for you and actually using it in your daily life are two very different things. I want to put together a Critical Thinking Toolkit.

One important tool is going to be Occam’s Razor: “entities must not be multiplied beyond necessity” (entia non sunt multiplicanda praeter necessitatem). That’s it in a nutshell right from William of Ockham, a Franciscan monk and English philosopher, theologian and logician in the 14th century.
Another way to put it is: The simplest explanation is usually the correct one. But don’t get confused by the term, simple. It means: The hypothesis with the fewest assumptions is usually the correct one. When giving explanatory reasons for something, don’t posit more than is necessary. Or, don’t make any more assumptions than you have to.

So let’s say you have 2 competing hypotheses that are basically equal in most respects. Then this principle would suggest that you choose the hypothesis that makes the fewest assumptions while still sufficiently answering the question. In science Occam’s Razor is used as a rule of thumb (a heuristic) to help researchers develop good models.

In your life it can help you make decisions and choose what to think and what to believe (or not believe). You can use it as a heuristic as well, a great rule of thumb in your Critical Thinking Toolkit.

Sometimes atheists use Occam’s Razor to argue against the existence of god since everything can be explained through natural means without complicating it with the supernatural.

Another example: Crop circles. There used to be 2 competing ideas for where crop circles came from. One was that flying saucers from an alien world made them. Another was that a person  (or people) used some type of instrument to make the designs in the grass. Since there is no evidence for the flying saucers from outer space, and given how complicated and how many assumptions need to be made to make that argument work, Occam’s Razor would suggest that the simpler explanation would be that humans did it with instruments. That is the argument that makes less assumptions.

Of course, the second argument could be wrong, but until there was more information, it was the preferable hypothesis. Then 2 guys admitted to the crop circle hoax in the 1990′s. So that ended that debate for most people.

A quote by Carl Sagan is appropriate here: Extraordinary claims require extraordinary evidence. When it comes to the supernatural, Occam’s Razor is a very valuable tool indeed.

For some time now, I’ve wanted to talk to you about critical thinking. I remember the bad old days when most of my thinking was emotional and reactive and I had no idea that such a thing as critical thinking even existed. It wasn’t a happy time. Over the last few years I’ve learned to think for myself and I can’t express how liberating and empowering that is.

If there is one gift you can give to a child or anyone else, it is to teach them to think for themselves. The educational system doesn’t teach this important skill. It teaches rote memorization and focuses on test taking. Therefore it’s up to you to learn it for yourself.

Unfortunately, I’m self taught and have no formal training in this realm. Which means sharing it with you is harder. So instead of putting it off even longer, I thought maybe we could explore the subject together and develop a plan for sharing with others in our lives or on the web. First, let’s define it.

Here is a quote: [Critical thinking is a] desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and hatred for every kind of imposture. ~ Francis Bacon (1605)

Here is the short and sweet definition:

Critical Thinking: n: the mental process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and evaluating information to reach an answer or conclusion. Read the rest of this entry »

Something that I have always found frustrating is how religious people (and people who are really into politics) are so dogmatic about their beliefs. As a skeptical atheist, I have come to realize that challenging peoples’ beliefs is usually frustrating, maddening, and completely fruitless. Well, Doctor Professor Luke Galen gave a talk recently called Terror Management: How Our Worldviews Help Us Deny Death. You can listen to the lecture through the Reasonable Doubts podcast (of which he’s a part): RD Extra: Denying Death, and you can see Dr. Galen’s slides here (pdf)

I know not all of you like to listen to podcasts. So I went through it and transcribed a good chunk of what Luke said in his lecture, the parts that I thought were most important. I have a few thoughts afterward. By the way, I missed the beginning for reasons I can’t remember (this took me a couple of days to make it all make sense) but this is a lecture about Dr. Ernest Becker and Terror Management Theory.

Partial transcript:

…This is where we get neurotic about death. It’s the ultimate inferiority complex. Our lifespan is limited. We realize we must die but in striving to overcome that, it creates more problems. We put a lot of energy into denying death.

One way to summarize Becker’s theory: It’s good to have a brain that can plan for the future and be self-aware, but the problem is that when we become scared of our own mortality it sets up a defense against that. Part of the defense involves symbols. We think symbolically and so our symbols set up a barrier. These symbols can be religious, political, symbols of our mastery over the world, symbols of making money, etc.

What Becker thought was that culture itself is a buffer against these threats to our self esteem. We set up our belief in culture and human culture really is an attempt to deal with threats to our own mortality and our self esteem. So first, what is self esteem?

Self esteem is not just a product of you, individually. What Becker thought was that self esteem was something you get a sense of only through other people. So you think of yourself as a valued person who has powers, who can act upon the world, but that is socially validated by parents, siblings, peers, a gradually expanding group of people. This gets more abstract and symbolic as the child grows up. So as a young adult you might latch onto ideologies. For many people this is religion. You join a church and get a sense of what you need to do to be good or bad from those groups too. The good thing is that these groups give you clear guidelines to derive your self esteem.

This can be positive or negative. So if you don’t get positive reinforcement, you’ll look for self esteem and validation in other ways. So this is why people join cults and gangs, etc. Read the rest of this entry »

One of my Facebook friends posted this to his feed today. Richard Dawkins waxing eloquent:

‎”The feeling of awed wonder that science can give us is one of the highest experiences of which the human psyche is capable. It is a deep aesthetic passion to rank with the finest that music and poetry can deliver. It is truly one of the things that make life worth living and it does so, if anything, more effectively if it convinces …us that the time we have for living is quite finite.”

“We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born. The potential people who could have been here in my place but who will in fact never see the light of day outnumber the sand grains of Sahara. Certainly those unborn ghosts include greater poets than Keats, scientists greater than Newton. We know this because the set of possible people allowed by our DNA so massively outnumbers the set of actual people. In the teeth of these stupefying odds it is you and I, in our ordinariness, that are here. We privileged few, who won the lottery of birth against all odds, how dare we whine at our inevitable return to that prior state from which the vast majority have never stirred?”

“An atheist is just somebody who feels about Yahweh the way any decent Christian feels about Thor or Baal or the golden calf. As has been said before, we are all atheists about most of the gods that humanity has ever believed in. Some of us just go one god further.” Read the rest of this entry »

Have you ever caught a glimpse of something out of your eye and thought, “oh that looked like a face!” “Look, Jesus is in my bar of soap!” “That cloud looks like a dog running!” That’s pareidolia. You see something random and your mind fills in the blanks so that you think something is there.

Pareidolia: a psychological phenomenon involving a vague and random stimulus (often an image or sound) being perceived as significant.

In psychology, the Rorschach test is a series of images used to invoke pareidolia to delve into the psyche of the patient. In religion and superstition, a vague stimulus is believed to be divinely sent. Here is a news story of Mary in bird shit. Notice how the people react to a random stimulus.

No matter how much I look at this picture, it looks like a face. The sink looks a bit shocked or frightened.

Carl Sagan hypothesized that detecting faces is a hard wired evolutionary advantage. This allows people to use only minimal details to recognize faces from a distance and in poor visibility but can also lead them to interpret random images or patterns of light and shade as being faces.

In 2009 a study was done to show that objects incidentally perceived as faces evoke an early (165 ms) activation in the ventral fusiform cortex, at a time and location similar to that evoked by faces, whereas other common objects do not evoke such activation. This activation is similar to a slightly earlier peak at 130 ms seen for images of real faces. The authors suggest that face perception evoked by face-like objects is a relatively early process, and not a late cognitive reinterpretation phenomenon.

Which would explain why everyone sees the following simple line drawing as a face: Read the rest of this entry »
