This gets me every time. Chemistry and, most certainly physical laws, are not indifferent to the sequence chosen.
The determinists are dependent on this fact. You might not be aware, and, apparently, Paul Davies is not aware that the DNA molecule interacts with a whole host of molecules in the environment, using laws of chemistry and physics. It's especially foolish to use this silly canard with respect to an argument about determinism. I'll boil down what his argument amounts to. Life is not dependent on universal laws because a particular reaction is not dependent on specific chemical bonds. He's making a gross generalization error based on anectdotal information.
I might have cut the article too short. Here are the paragraphs that followed the paragraph you quoted through the next excerpt at 4507:
This argument is, however, flawed. The building blocks of life are easy to make because their synthesis is thermodynamically favoured. But stringing them together in an aqueous environment into complex molecular chains like proteins and RNA is thermodynamically uphill. Just as a pile of bricks alone dont make a house, so organic building blocks alone dont make life. Put a stick of dynamite under a pile of bricks, and you dont make a house, you just make a mess. In the same way, merely throwing energy willy-nilly at a collection of amino acids, for example, to drive it against the thermodynamic gradient, wont produce a protein. Just as a house requires the delicate assembly of bricks into an elaborate and specific arrangement, so amino acids need to be carefully linked in a precise way to make a functional protein, rather than gunk. The same goes for nucleic acids.
A hundred years ago, it was commonly supposed that life is some sort of magic matter, and that lifes origin would be analogous to baking a cake. All it needs is the right ingredients mixed in the right order under the right conditions. Today we know that the living cell is less magic matter, more a supercomputer; i.e. it is an information processing and replicating system. The key property that distinguishes life from other forms of complexity is the informational aspect, the message in the genes. Chemistry cannot explain information. Chemistry is the medium of life, but one must not confuse the medium with the message.
This gets me every time. Chemistry and, most certainly physical laws, are not indifferent to the sequence chosen.
Totally false. The power of DNA is that the different 'letters' can be arranged in any way possible. This is shown by a simple table of how the symbols in the DNA code are translated into amino acids. All 64 possible combinations have been found to be used in life.
Paul Davies is not aware that the DNA molecule interacts with a whole host of molecules in the environment, using laws of chemistry and physics.
I am sure he is quite aware of it. In fact that is what makes DNA so special - the code, to be useful and sustain life, has to be arranged in such a way as to provide for the functions needed for life. These functions have to be in accordance with the rest of reality and it has to take account of how this is to be accomplished. So you have it absolutely backwards - like most materialists and evolutionists. You are going from what exists and are saying that because something exists the means for its existance had to have arisen deterministically. This is totally false backwards. The effect is not the source of the cause. The determinists are dependent on this fact. You might not be aware, and, apparently, Paul Davies is not aware that the DNA molecule interacts with a whole host of molecules in the environment, using laws of chemistry and physics. It's especially foolish to use this silly canard with respect to an argument about determinism. I'll boil down what his argument amounts to.
