A Quote by Michael Behe
Irreducible complexity is a problem for Darwinian evolution. Whenever we see these complex functional systems we realise that they have to be designed.

People have a hard time accepting free-market economics for the same reason they have a hard time accepting evolution: it is counterintuitive. Life looks intelligently designed, so our natural inclination is to infer that there must be an intelligent designer--a God. Similarly, the economy looks designed, so our natural inclination is to infer that we need a designer--a government. In fact, emergence and complexity theory explains how the principles of self-organization and emergence cause complex systems to arise from simple systems without a top-down designer.
I came to realise that Darwinian evolution had no explanation of me as an experiencing self.
The general problem with ambitious systems is complexity. [...] it is important to emphasize the value of simplicity and elegance, for complexity has a way of compounding difficulties.
Complexity is not a goal. I don't want to be remembered as an engineer of complex systems.
The primary consequence of the computational nature of the universe is that the universe naturally generates complex systems, such as life. Although the basic laws of physics are comparatively simple in form, they give rise, because they are computationally universal, to systems of enormous complexity.
New laws, new kinds of things can emerge as the universe evolves. The more moving parts you have in something, the more possibilities there are. There's a whole new science now of complexity, and what we see is that complexity requires a very different approach than the kind of bottom-up approach that fundamental physics has always used. We're gonna have to think about the world in a different way if we want to address complex systems.
As we build systems that are more and more complex, we make more and more subtle but very high-impact mistakes. As we use computers for more things and as we build more complex systems, this problem of unreliability and insecurity is actually getting worse, with no real sign of abating anytime soon.
Nowadays theologians aren't quite so straightforward as Paley. They don't point to complex living mechanisms and say that they are self-evidently designed by a creator, just like a watch. But there is a tendency to point to them and say 'It is impossible to believe' that such complexity, or such perfection, could have evolved by natural selection. Whenever I read such a remark, I always feel like writing 'Speak for yourself' in the margin.
Intelligent design cannot explain Darwinian evolution. Darwin's whole point is that variation and change are random and without higher purpose. We cannot imagine that God designed this disproof of His own existence.
The people working in my field also are quite skeptical of our ability to do this. It ultimately boils down to the problem of building complex systems that are reliable and that work, and that problem has long predated the problem of access to encryption keys.
As far as I can see, our concentration of different abilities in one species - there's nothing I can see that in this Darwinian evolution that could've done that. So it seems to be a miracle of some sort.
Creationists have also changed their name ... to intelligent design theorists who study 'irreducible complexity' and the 'abrupt appearance' of life-yet more jargon for 'God did it.' ... Notice that they have no interest in replacing evolution with native American creation myths or including the Code of Hammarabi alongside the posting of the Ten Commandments in public schools.
In the abstract, it might be tempting to imagine that irreducible complexity simply requires multiple simultaneous mutations - that evolution might be far chancier than we thought, but still possible. Such an appeal to brute luck can never be refuted... Luck is metaphysical speculation; scientific explanations invoke causes.
If we want to postulate a deity capable of engineering all the organized complexity in the world, either instantaneously or by guiding evolution, that deity must have been vastly complex in the first place. The creationist, whether a naive Bible-thumper or an educated bishop, simply postulates an already existing being of prodigious intelligence and complexity. If we are going to allow ourselves the luxury of postulating organized complexity without offering an explanation, we might as well make a job of it and simply postulate the existence of life as we know it!
The barrier to change is not too little caring; it is too much complexity. To turn caring into action, we need to see a problem, see a solution, and see the impact. But complexity blocks all three steps.
It's us that's really amazing. As far as I can see, our concentration of different abilities in one species - there's nothing I can see that in this Darwinian evolution that could've done that. So it seems to be a miracle of some sort.
