A Universe Not Made For Us: Carl Sagan

I found this video the other day and wanted to share it with you. It’s Carl Sagan reading from his book, Pale Blue Dot: A Vision of the Human Future in Space, from the chapter titled A Universe Not Made For Us.

I read a Terry Pratchett book recently called Reaper Man (it was great, of course). In it, he said, “In the Ramtop village where they dance the real Morris dance, for example, they believe that no one is finally dead until the ripples they cause in the world die away – until the clock he wound up winds down, until the wine she made has finished its ferment, until the crop they planted is harvested. The span of someone’s life, they say, is only the core of their actual existence.”

In that sense, Carl Sagan is still very much alive.

Evolution Before Darwin

Contrary to many assumptions, evolutionary theory did not begin in 1859 with Charles Darwin and The Origin of Species. Rather, evolution-like ideas had existed since the times of the Greeks, and had been in and out of favor in the periods between ancient Greece and Victorian England. Indeed, by Darwin’s time the idea of evolution – called “descent with modification” – was not especially controversial, and several other evolutionary theories had already been proposed. Darwin may stand at the beginning of a modern tradition, but he is also the final culmination of an ancient speculation.

Evolution in Greece

While the Greeks did not specifically refer to their concepts as “evolution”, they did have a philosophical notion of descent with modification. Several different Greek philosophers subscribed to a concept of origination, arguing that all things originated from water or air. Another common concept was the idea that all things descended from one central, guiding principle.

Thales ( 624 – 546 BCE): asserted that all things originated from water.
Anaximander (610 – 546 BCE): With his assertion that physical forces, rather than supernatural means, create order in the universe, Anaximander can be considered the first scientist. He is known to have conducted the earliest recorded scientific experiment. He suggested that living beings gradually developed from moisture with warmth. He also thought that the first humans were born, fully formed, from the wombs of fish, since they needed care for a long time.
Anaximenes (585 – 528 BCE): Thought air was the principle of all things, and regarded the process as a thinning or thickening.
Empedocles (490 – 430 BCE): Thought that the first creatures were not fully formed but consisted of unconnected limbs. He established the concept of everything in the universe being made up of four elements: fire, air, water and earth, which was the standard for the next two thousand years.
Aristotle (384 – 322 BCE): The Great Chain of Being: He thought there was a transition between the living and the nonliving, and theorized that in all things there is a constant desire to move from the lower to the higher, finally becoming the divine.
Lucretius (99 – 55 BCE): He was the first to suggest extinctions and that the survivors survived by “cunning or speed”.

A Wild Ride With Robert Sapolsky

My friend Brent sent me a link to a page on the web. It’s a conversation with Robert Sapolsky, a quiet, funny, apparently brilliant professor of biological sciences at Stanford University and of neurology at Stanford’s School of Medicine. Professor Sapolsky has written several books such as:

The link Brent sent me was called TOXO and he suggested it to me because our book club is reading The God Virus: How religion infects our lives and culture, by Daniel W Ray. Now the video on that page was Robert Sapolsky talking about a most interesting parasite called Toxoplasma. This is what pregnant women need to worry about, and why they avoid cats and cat feces. It can wreak havoc on their unborn baby’s nervous system.

If you read The God Virus, which talks about parasites and viruses as an analogy for religion, I highly recommend watching this video. If you aren’t going to read the book I still recommend the video. The transcript is underneath it too, which will make it even more accessible for you. But the video is longer than the transcript. So take 25 minutes and enjoy it. Here’s another link to the video. I’m telling you, it’s fascinating. As I mentioned, the video is longer than the transcript. He goes into telemeres and molecular age, which I heard a study about recently confirming what he is explaining.

What he’s talking about touches on evolution, common ancestors, parasites and how they go about getting where they need to be, motorcyclists and speed freaks, and schizophrenics, as well as the government’s interest in this parasite. A wild ride indeed! Read the rest of this entry »

Don’t Give Up!

To the Freethought Society of Greater Philadelphia, don’t give up! Fight the good fight!

I just read an article by Staks Rosch in the Philadelphia Examiner about the FSGP and their Tree of Knowledge. It’s an evergreen tree decorated with book covers (how shocking, how impudent!) from books representing knowledge, education, science, philosophy, morality, diversity and curiosity. (I am so offended! What? No Twilight?! No Dan Brown?!) Here is a complete list of the books represented.

Staks makes some points that I really like: “[The Tree of Knowledge] is not an attack on religion, but rather an expression of an alternative set of values (i.e. knowledge and reason).”

How horrific! Now I understand why the good christians of the area are so up in arms, vandalizing the tree and organizing call campaigns to get it removed. And why the county is bending to the will of one religion on government property. It’s just so hateful to have a tree decorated with thoughtful, intelligent books. What? Oh? It’s not threatening at all? EXACTLY! WTF!

Staks also says, “Many Christians have claimed that the inclusion of humanist values next to the Jesus Crèche is an attempt to “steal” Christmas. It seems that many Christians are of the opinion that Christians own the winter season. They do not.”

Later he says, “Atheists aren’t trying to “steal” Christmas any more than Christians stole Saturnalia… oh wait, never mind.” Again, I agree completely.

This kind of thing makes me so angry. Religious organizations bully their way into having their cake and eating it too. Politicians and the masses alike bend to that will for what reason? Why do they get to own most holidays? My sister in law is offended when I say happy holidays instead of merry christmas. It’s the classic bully at the pulpit who then cries and runs for the government to protect him when someone brings up that he’s breaking the law or that he’s being a bully.

christians and muslims don’t want to play fair. They want to win. Which is why I am an activist atheist. I don’t want to be forced to pray to a man in the sky that doesn’t exist. I am moral and ethical on my own without being forced into the barbaric false ethics of an iron aged society of goat herders from the Middle East.

I suppose here in Morgantown, if such inequities are occurring, we’ll put up an atheist/humanist display soon too. At this time, I am not aware of any. But I haven’t checked every government building lawn for crèches either.

Keep an eye out in your town. If you see religious displays on government property, take action, form a group. You can then turn it into a community of like-minded people like we’ve got here in our sleepy little town. It’s the most wonderful feeling to hang out with a bunch of freethinkers. But don’t just take things lying down. Don’t let the religious people bully us into giving up our freedoms and our constitutional rights just because we are too apathetic to make a stand for those rights.

EDIT: The Freethought Society of Greater Philadelphia has helpful hints for setting up your own Tree of Knowledge.

Some Great Advice by Robert Gula

I belong to a book club that has been reading Nonsense: Red Herrings, Straw Men and Sacred Cows: How We Abuse Logic in Our Everyday Language by Robert J. Gula.

I really wanted to share part of chapter 17 with you. Mr. Gula lists the most important principles to be gleaned from the rest of the book. I highly recommend getting the book and reading it. It has really helped me think more logically. The other thing it’s helped me with is to realize when someone has used a logical fallacy on me. I might not remember the name, but I remember that it is nonsense. It sort of gives me a red flag when someone uses bad logic in an argument. I think that’s pretty invaluable.

So here’s the list of important principles from Robert Gula: Read the rest of this entry »

How People Tend To Think And Respond

In our book club right now, we are reading Nonsense: Red Herrings, Straw Men and Sacred Cows: How We Abuse Logic in Our Everyday Language by Robert J. Gula. It’s very interesting as it goes through emotional language and logical fallacies in several ways that make them easier to understand. Robert Gula wrote the book in the 1970′s which is interesting in its nostalgic examples.

But what I wanted to share with you was something from chapter 1 that I thought was quite valuable:

First, some general principles. Let’s not call them laws; and since they’re not particularly original, I won’t attach my name to them. They are merely a description of patterns that seem to characterize the ways that people tend to respond and think. For example, people: Read the rest of this entry »

Dawkins on the Colbert Report

Here is a video clip from the Colbert Report the other night (Sept 30). Stephen Colbert interviews Richard Dawkins. It’s almost 6 minutes long:
