The world is getting better

I recently finished Harvard Professor Steven Pinker's most recent book called "The better angels of our human nature: Why violence has declined". This 1000 page book Pinker argues convincingly that all categories of violence (war, murder, assaults, and rape) has decreased substantially throughout history. What about the 2WW with 50 million plus deaths. While this was indeed the most destructive war in terms of the absolute number of dead people, it is not the most destructive if you look at the percentage. Genghis Khan for instance, in his raids reached a 40 million figure almost a thousand years ago, a huge proportion of the people around at that time. In other words, for the average individual it was way more dangerous in Genghis Khans time than when Hitler was alive.



Importantly the number of wars have decreased throughout history and since the 2WW there have been fewer wars than ever before (despite serious tensions during the cold war I may add). It is of course easy to think that there are a lot of wars because almost every war is covered in the media in a way that is quite new.

Likewise the murder rate has gone from 50-100 persons per 100.000 per year in the middle ages to an average that is lower than 10 persons per 100.000 per year in the west today (in Sweden where I live the rate is more like 1 person in 100.000 per year).

Why has violence decreased so much? Pinker argues, and after reading his book I agree, that the main historical factor is the development of states i.e. an uninterested third party that can settle disputes that would previously spark violence. To call a state "uninterested" may be an overstatement since in order to flourish it is in the states interest that its subjects do not fight. Apart from this rationale Pinker also presents a large amount of data showing that the establishment of a state is correlated with a strong decrease in violence.

The other main factor Pinker argues is responsible for the decline of violence is rational-abstract thinking. Today we live in a global world, and like never before we get to peek into other peoples lives, even if they live on the other side of the globe. It is almost impossible and it is definitely not socially acceptable to dismiss other peoples suffering just because they live in another country.

If this sounds interesting, listen to the TED lecture with Pinker where he gives you a short outline.
Another authors who has similar ideas although his explanation is somewhat different is Matt Ridley, listen to him below.

My favorite podcasts - Best podcasts

I have not been blogging for quite a while, however, this blog is not dead. The reason for my inactivity has been twofold. I have discovered podcasts (more about that in a moment) and I have become a father for the second time. These two "hobbies" of mine have consumed all my spare time and therefore the blog has suffered a bit, but I still feel I have a lot to write about and share with those who are interested.

If you have read any of my previous posts you will probably know that I am a great fan of The Teaching Company, a company that offers great courses for download (read my previous posts here.

Recently I have however mostly been listening to podcasts and I thought I would write a little about my favorite podcasts here. Unlike the teaching company courses, podcasts are normally free to download, although some depend on donations.

1. Skeptics Guide to the Universe - This is the podcast that I look forward to the most every week. Host, Steven Novella (a neurologist) and his fellow rouges discuss science news and discoveries from a skeptical perspective. You learn a lot of science by listening to this show and it is also highly entertaining in my opinion. Fantastic show really.

2. Skeptoid - Another excellent learning resource. Brian Dunning guides you through original sources on many issues including "was the pyramids built by slaves", "is asparthame dangerous (its not)", "organic vs conventional farming", "roswell" and many other topics. Dunning is also not afraid to admit that the jury is still out there if that is the case - he never makes conclusions that go beyond the evidence he has presented - great podcast.

3. Hardcore History and Common Sense - Reporter and excellent storyteller Dan Carlin is the man behind both of these two podcasts. In Hardcore History Carlin gives you some of the best accounts of various historical episodes that I have heard - I especially liked his four part podcast on "Ghosts on the Osfront" about operation Barbarossa - if you are the least bit interested in the second world war this is a must. In "Common Sense" Carlin sits and talks for himself about current events in the news, giving his perspective on things - and according to himself he always manages to piss of someone...

4. Dr.Karl and the Naked Scientist - Great science podcast. Although perhaps not as entertaining as the Skeptics guide to the galaxy this podcast is always very informative and it takes you through the biggest current science news in a way that most people can manage (unlike actually reading Nature and Science which many people find difficult). Some programs are Q&A where listeners can ask about any science question. I always learn a great deal from listening to this podcast.

5. This Week In Tech (TWIT) - This podcast is all about gadgets and new technology and is a great way for me to satisfy my need to hear about the most recent developments. If this is something you like too then I highly recommend this podcast.

6. 60-second science podcasts. "Scientific American" gives you three different 60-second long podcast where they take one news item and explains it very clearly in about 60 seconds, quite impressive if you ask me. Since I am into neuroscience my favorite is 60 second psych, but there is also 60-second earth and then there is the more general 60-science. They also have a longer show called Science Talk where they interview authors of important scientific publications. Also a great show.

7. NeuroPod - Official podcast of the journal "Nature Neuroscience". It simply takes you through their publications - much faster than it takes you to read the journal. Good resource for anyone into the field of Neuroscience.

8. ESPN Soccernet podcast - I am a science nerd and but I also love soccer and especially the Premier League. This podcast gives you all the analysis and transfer gossip you can handle.

9. Quackcast - Mark Crislip gives all medical quacks out there a hard time. If you think that vaccinations are dangerous or that conventional medicine is just one big conspiracy I hope that you will give this podcast a chance.

10. Rationally Speaking - Massimo Pigliucci has another another great podcast based on a skeptical approach. Because he is a philosopher he also gives a different perspective than Steven Novella from Skeptics Guide to the Galaxy. Another podcast which is also interesting and informative.

Swedish podasts:

1. SkeptikerPodden - Sveriges "Skeptics Guide to the Universe". Underhållande och informativ och med intressanta reportage. Min favorit är när ett Medium får kontakt med en död mor - bara det att modern aldrig var död... hmmmm. Bra jobbat SkeptikerPodden!

2. Godmorgon Världen - Enligt mig det bästa veckomagasinet med nyheter som finns.

Apollonius of Tyana

About 2000 years ago a pregnant woman got a visit from a heavenly agent who told the mother-to-be that her son would be the son of God. His birth which was associated with some supernatural signs and as a boy he made himself a name among the religious leader. When he got older he left his home to walk around from town to town and convinced people to give up on their material belongings and instead focus on the spiritual dimension of life.

His followers were convinced that their teacher was divine, and indeed he was able to heal the sick as well as casting out daemons. Towards the end of his life he was prosecuted by the roman authorities, and then he disappeared. However, even after he were gone, his followers continued to believe in him and there are even reports of him showing up after he was dead. He came down from heaven to convince the spectators that there is a life after death.

Does this man sound familiar to you? Who am I talking about? Many books have been written about this pagan philosopher. His name is Apollonius of Tyana and his historical existence is not disputed due to the fact that there are several independent sources. These survive in spite of the fact that the catholic church actively tried to destroy all records of Apollonius existence. Apollonius followers had heard about Jesus and they believe he was a fake.

I did not hear about this man Apollonius until recently and I must admit that I was quite surprised to hear that Jesus is not unique at all, at least not if you go by historical documents which is really the only proper way to go about if you do not want use subjective arguments such as "I feel (or know) that Jesus existed and that he did all those things written about in the gospel".

I have found a number of webpages claiming that a lot of what is written in the New Testament was really about Apollonius and that only later was names changed. This could explain some of the discrepancies between different books of the bible, but I guess it is very hard to tell one way or the other. I am no historian so I will merely say that I find it unlikely that those who wrote the New Testament had not been influenced by the books or tales about Apollonius in any sense. The stories of Jesus and Apollonius of Tyana simply have too much in common with each other for everything to just be random chance
