Transhumanism: The World’s Most Dangerous Idea? (Nick Bostrom)

So tonight I am attending a Tippling Philosophers get-together in Fareham, UK. We are discussing transhumanism. For those who don;t know, this is the idea (or movement for the idea) that we can adapt our bodies and cognitive abilities using technology to prolong our lives, choose our babies genotype and phenotype etc etc – the harnessing of technology to change and progress what we might (erroneously?) define as our humanity, biological or otherwise.

Human Influence On Climate Clear, IPCC Report Says

The Independent reports: Scientists ‘95 per cent certain’ that climate change is man-made

But this article is from Science Daily:

The Independent reports: Scientists ‘95 per cent certain’ that climate change is man-made. I wonder whether science denialists will ever concede.

But this article is from Science Daily:

Sep. 27, 2013 — Human influence on the climate system is clear. This is evident in most regions of the globe, a new assessment by the Intergovernmental Panel on Climate Change (IPCC) concludes.

Quotes of the Day by Andy Schueler

Recently, Zytigon, a skeptic who comments on Debunking Christianity, noticed a comment on a anthropogenic global warming denial blog entry by a Johnathan Pearce, thought it was me, understandably. The spelling, though, is slightly different and this person was not me. I support the scientific consensus on global warming agreed by an overwhelming proportion of scientists in the relevant fields.

Computer Can Read Letters Directly from the Brain

By analysing MRI images of the brain with an elegant mathematical model, it is possible to reconstruct thoughts more accurately than ever before. In this way, researchers from Radboud University Nijmegen have succeeded in determining which letter a test subject was looking at.

The journal Neuroimage has accepted the article, which will be published soon.

The Argument from Format – How the Cartesian soul cannot be the originator of free will

This essay sets out to dispel the myth that the soul can be the originator for free will. I will start the essay by establishing the Cartesian idea of what the body is and showing that Descartes and modern biology indicate that the body is a biological machine. After indicating how Descartes (and others) use the soul as the originator for free will / volition, I will show that in order for the soul to be labelled and identified as a soul, it must have the format and properties of a soul. These must be adhered to in order to designate the soul with coherent and consistent properties. To conclude, I will maintain that if a soul must adhere to rules and laws to remain being a soul, then it must operate within a deterministic framework.

Neuroscientists Plant False Memories in Mice: Location Where Brain Stores Memory Traces, Both False and Authentic, Pinpointed

This hit the news yesterday on radio and TV. Fascinating stuff. This reported from Science Daily:

July 25, 2013 — The phenomenon of false memory has been well-documented: In many court cases, defendants have been found guilty based on testimony from witnesses and victims who were sure of their recollections, but DNA evidence later overturned the conviction.

Can Science Test Supernatural Worldviews?

Yonatan Fishman, PhD, Department of Neurology, Albert Einstein College of Medicine, wrote a really interesting paper contesting the idea that science and the supernatural do not overlap, and that there is no way to test the supernatural. The paper can be found here and is well worth a read. I hope to give it a greater commentary in the near, not-so-mentally busy future!

Lizards Show Evolution Is Predictable

Science Daily – July 19, 2013 — If you could hit the reset button on evolution and start over, would essentially the same species appear? Yes, according to a study of Caribbean lizards by researchers at the University of California, Davis, Harvard University and the University of Massachusetts. The work is published July 19 in the journal Science.
