Evolutionary algorithms and the Lovelace Test

Posted on 11/08/2014 by Jon Garvey

This article is interesting. It seems AI computer boffs needed a better test than the Turing Test for Hard Artificial Intelligence, should it ever arrive, given the subjective and easily manipulable results of the Turing Test recently. The original publication is here. As you’ll see, the test involves demonstrating a computer outputting something that was not designed into it in the original program – and should that ever happen, the computer will be shown to be truly intelligent, according to those best qualified to say.

Levels of certainty

Posted on 10/08/2014 by Jon Garvey

The 2009 Rescuing Darwin survey, to which I referred in a previous post,  was linked to a long essay by Nick Spencer and Denis Alexander, both theistic evolutionists by persuasion. Their own spin on the survey results is evident from early on in their essay (and perhaps even in the project’s title):

Deep time – what’s the story?

Posted on 08/08/2014 by Jon Garvey

When one draws back from the “evolution is a proven fact” polemic, and aims to pin things down more rigorously, the least-contestable parts of the received scientific wisdom, vague as that is overall in the public arena, are the great age of the earth, and the succession of species (as opposed to common descent, which has some strong evidence but of a more inferential kind). Deep time’s strongest theological suit, in my book, is that a careful reading of the Bible makes no statement about the time of the creation – the chronological evidence of histories and genealogies actually takes one back to Adam, and it is an inference that … Continue reading →

Law and nature

Posted on 07/08/2014 by Jon Garvey

GD mentions in a recent comment how the Aristotelian concept of nature’s predictability is fundamentally different from that of modern science. To previous generations of natural philosophers, habitual actions were the result of the forms applied to matter by God. They were the intrinsic tendencies of substantial forms, and so part of their essential natures.

More on selection, optimization and doubt

Posted on 05/08/2014 by Jon Garvey

I want to expand a little on why I have conceptual problems with standard Neodarwinian evolution as a more-or-less complete explanation for the origin of the species, touching again on optimization, which I dealt with recently in the context of formal causation.

Creation and Magic

Posted on 31/07/2014 by Jon Garvey

The discussion on God’s “magical” activity on a previous thread managed to jettison the theme of the thread, and the overall theme of the blog too, that is the doctrine of creation. But it’s actually worth devoting a post to the subject of magic, because in many ways it is a magical understanding of the cosmos that the biblical creation doctrine subverted.

Complex systems and top-down causation

Posted on 30/07/2014 by Jon Garvey

Lest you think that my last post  was merely whimsical (which seems a popular word here recently) have a look at the following YouTube talk by George F Ellis (quoted in that post), whose speciality as a physicist is complex systems.

Form, health and optimization

Posted on 29/07/2014 by Jon Garvey

One of the things that used to intigue me when I was in medicine (in those occasional philosophical moments) was the fact that, though I spent my life combating disease, it was rather hard to pin down what health actually is. The 1946 WHO definition of health is very worthy, but totally impractical: “A state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.” Whilst I had a pretty holistic approach, I wasn’t going to sort out people’s social lives, and for some reason it was officially frowned upon to improve their mental well-being by sharing the gospel with them. But I knew reliably, … Continue reading →

Great journeys

Posted on 27/07/2014 by Jon Garvey

I’ve mentioned the swallows nesting in our stable in passing on a couple of posts. They’re now on their second brood (on a second nest, atop a second light-fitting, for some reason – failure to find a valeting service locally, perhaps?). It’s astonishing that within a month or so those parents, and both new broods, will be making their way to South Africa.

The myth behind the myth

Posted on 24/07/2014 by Jon Garvey

In the last post I referenced C S Lewis’s essay on the modern Myth of “Evolutionism” (as distinct from the scientific theory of evolution, just to remind you…), of which one major, and undoubtedly correct, point is that the ideological motivation to believe in evolution as an overarching principle precedes Darwin’s biological theory by several decades. But Lewis doesn’t attempt to explain fully why it should have developed in the first place. Here’s my attempt to do so.
