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.

Enduring myths and their aftermath

Posted on 23/07/2014 by Jon Garvey

When I cited Os Guinness in a recent post, I noticed a reference to an important essay by C S Lewis whilst re-reading Guinness’s assessment of humanism. It’s well worth reading, though from the 1940s, and gives that feeling you always get with Lewis that, although a mediaevalist, he was half a century ahead of his time.

When stories become science (and when they don’t)

Posted on 21/07/2014 by Jon Garvey

I hesitate to continue on the subject of maths in evolution, as it takes us into some deep philosophical waters, and especially as evolutionary programming is outside my comfort zone. But some useful stuff arose from the comments on previous threads, and there may be a couple of posts in it to make us think more critically.

On metabiology, natural law and divine action

Posted on 19/07/2014 by Jon Garvey

I’d like to pick up on a remark made by our friend Darek Barefoot on a recent thread: God may be working outside the pattern of lawlike regularities in countless irregular nudges of the genetic code, but given how many of these nudges there seem to have been it becomes difficult to distinguish them from lawlike regularities.

Frontloading, maths and logic

Posted on 17/07/2014 by Jon Garvey

After our worthwhile diversion into the christology of creation for three posts, I want to drop back briefly to the previous discussion on frontloading, natural v supernatural action in nature and so on. A post on Uncommon Descent about scorpion burrows prompted  one of my infrequent comments there.
