## ID and the 2LoT

I keep hearing from cdesign proponentsists that ID is not creationism. That ID is totally a scientific theory with predictions and everything that they’d love to show except the dog ate their lab notes the mean old bourgeois scientific establishment is suppressing the truth.

And then Bill Dembski posts this:

The 2nd Law of Thermodynamics has never been a friend of materialistic evolution. Granville Sewell’s arguments concerning it at the following two links are worth pondering:

You can read the preface (PDF) of the Disco Tute’s latest emesis, in which Granville Sewell writes:

The origin and development of life seem to violate the second law of thermodynamics in a clear and spectacular way; however, such arguments are routinely dismissed by saying that the second law does not apply to open systems, such as the Earth. The author counters this idea with the tautology that “if an increase in order is extremely improbable when a system is closed, it is still extremely improbable when the system is open, unless something is entering which makes it not extremely improbable.”

Sewell either doesn’t understand the 2nd Law of Thermodynamics, or he’s deliberately lying.

Perhaps the most layman-friendly version of the 2LoT is

Heat generally cannot flow spontaneously from a material at lower temperature to a material at higher temperature.

Right now, I’m sipping a drink with ice cubes in it. How did those ice cubes form? I started out with water at room temperature (say, about 20°C). My freezer then “sucked” the heat out of the water, bringing it to 15°C, then 10°C, then finally 0°C when it froze. And where did that heat go? Into the room.

You can test this for yourself: go stand by the back of a fridge, or an air conditioner, and you’ll feel that the air coming out is slightly warmer than the ambient air.

In other words, what my freezer does is move heat from a material at lower temperature (the water) to a material at higher temperature (the air in the room).

But note that the 2LoT says “spontaneously”. That’s a key word. The only reason my freezer works is that it’s getting electrical energy from the wall socket. If you put water into a freezer that hasn’t been plugged in, it’s never going to spontaneously freeze, any more than water will spontaneously go uphill.

But it’s possible to pull heat out of a colder object and into a warmer one using a freezer, just as it’s possible to move water uphill using a pump. But both of these come at a cost: you have to keep adding energy into the system. If you pyt a small amount of energy into your pump, you can move a small amount of water uphill; if you want to move a lot of water uphill, you need to put more energy into the pump. Ditto with freezers. It’s possible to freeze Lake Michigan in a week, but not with a common household freezer.

Sewell’s rebuttal to people who actually know what the fuck they’re talking about is:

if an increase in order is extremely improbable when a system is closed, it is still extremely improbable when the system is open, unless something is entering which makes it not extremely improbable.

That “something [which] is entering” is sunlight. If I put my freezer inside a capsule (insulated against heat loss) at 20°C, then shoot the capsule into space, and put water in the ice tray in the freezer, it’ll never turn into ice.

But if I then hook the freezer up to a solar panel, and point the panel at the sun, then yes, the freezer will cool the water and heat up the rest of the capsule. But then the capsule is no longer a closed system, since energy from sunlight is entering it. And thus, something that’s very very improbable (read: impossible) in a closed system becomes possible in an open system.

In fact, that’s what photosynthesis is: plants take energy from sunlight, and use it to force CO2 and water molecules together against their wish, to make sugar molecules. The sugars can then be broken up to release energy where it’s needed. It’s like using a solar panel to charge batteries that can then be used wherever they’re needed.

I’ll leave you with Sewell’s conclusion, a dumb-bomb of such potent moronicity that it ought to be banned by international arms treaties:

The conclusion: “If we found evidence that DNA, auto parts, computer chips, and books entered through the Earth’s atmosphere at some time in the past, then perhaps the appearance of humans, cars, computers, and encyclopedias on a previously barren planet could be explained without postulating a violation of the second law here. But if all we see entering is radiation and meteorite fragments, it seems clear that what is entering through the boundary cannot explain the increase in order observed here.”
