Computers, Brains and Accountability

I spent a good part of my working life programming computers. I started in the late 60’s, almost fifty years ago. Back then, computers were the size of houses, and the programs were punched on cards. Data storage was on magnetic tape. Processors were slow and memory was small. But in the early 70’s when the microelectronics explosion happened, memories grew from kilobytes to megabytes to gigabytes to terabytes. Processor speed accelerated from kilohertz to megahertz to gigahertz. And of course the cost went down and down and down. Today, most kids carry one around in their pocket.

Evolution, language and the unconcsious: yup, free will again!

John D. Bargh is a psychologist with an interest in matters concerning free will. He edited a superb book on psychology and free will which I would advise anyone to get called Are We Free? From it, this excerpt was interesting, especially given recent conversations defending naturalism with a fellow Tippling Philosopher by email who thinks that human minds are too far removed from the rest of the animal kingdom to be explicable by naturalistic evolution (pp. 145-146):

Steve Novella on consciousness: dualism is the new evolution for theists (Part 1)

I was listening to a Reasonable Doubts podcast from a few years ago, and it was, as ever, cracking. This one was about consciousness, its hard problem, dualism, and how it, and neuroscience, are being co-opted as a philosophical area to argue for the “God of the Gaps” style argument in the same vein as evolution in the creationist and intelligent design movements.

On editing memories

I reported in my Free Will? book that we can laser in memories to fruit flies, so it was only a matter of time before such procedures were contextualised to humans. Scientific American reports:

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 ‘Why I am a Christian’ series – Vincent Torley of Uncommon Descent (Part 4)

After having looked at Randal Rauser’s reasons for being a Christian, and having had my reasons and his defences intensely debated on his blog, I have in a previous posts (linked below) offered Dr Vincent Torley’s account. Some readers may know Vincent from the Uncommon Descent website which attempts to refute evolution. I have argued with him at length when I used to write for John Loftus more often at Debunking Christianity. Here is his bio:

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.

First interview with a dead man

New Scientist has started a new feature series on people with bizarre and rare mind / brain disorders and predicaments. This article looks at Cotard’s syndrome. What is fascinating about this article and syndrome is the interplay between brain, consciousness and self-awareness. That these conscious states arise from brian patterns:
“When I was in hospital I kept on telling them that the tablets weren’t going to do me any good ’cause my brain was dead. I lost my sense of smell and taste. I didn’t need to eat, or speak, or do anything. I ended up spending time in the graveyard because that was the closest I could get to death.”
