The Article is well worth reading as well as this discussion. I think the image of Gaia improved the article. I fixed the spelling here and will fix a few more. The poverty of spelling ability on this page reflects (IMHO) the poverty of clear thinking in the whole analogy, mostly or all on the "pro-analogy" side. Even multiple editors can't spell ("rearrangments"). I liked the bit about money growing on trees. Cute. Carrionluggage 22:16, 18 December 2006 (UTC)

[edit] History
Monotheists have suggested: if we find a watch in a field, it is too complex to have appeared there by natural process so they assume that there must have been a watchmaker responsible for its creation. Similarly, the argument goes, life is extremely complex and requires a creator. Polytheists have pointed out that the more historically correct assumption would be that a great multitude of people had contributed to the creation of the watch. The analogy then requires multiple creators.
The historical accuracy of single watchmaker vs a great multitude of contributors, comes into play in the Intelligent Design debate. The two sets of assumptions in the watchmaker analogy are one of the few reasoned arguments differentiating between the appropriateness of Monotheism vs Polytheism. If Intelligent Design is to be taught in science classes, the principle of parsimony, combined with the history of watchmaking, will require the teaching of polytheism as correct.
[edit] The watchmaker analogy before Paley
The Roman Cicero used ideas which later developed into the subject of this article. For Romans Tellus was the Romanised version of the Greek goddess, Gaia. Gaia played an important part in the Creation mythology of Ancient Greece. Creation mythology of traditional religions frequently gives a prominent role to a Mother goddess who gives birth to other things in creation. Frequently also love-making is involved. Gaia in some versions of the story made love to her son, Ouranos. Other parts of creation arose from this union. Cicero, by contrast, claimed that Caelus, the Romanised form of Ouranos, was the offspring of the ancient gods Aether and Hemera.
The Watchmaker analogy was anticipated by Cicero (106 BC – 43 BC) in De natura deorum, (About the nature of the gods), ii. 34 Cicero wrote in a polytheist context about what he thought was the design of the universe.
When you see a sundial or a water-clock, you see that it tells the time by design and not by chance. How then can you imagine that the universe as a whole is devoid of purpose and intelligence, when it embraces everything, including these artifacts themselves and their artificers?
– Cicero, quoted by Dennett 1995, p. 29, (Gjertsen 1989, p. 199)
This article seems to make little sense. While the article describes the watchmaker analogy as a false analogy, the watchmaker analogy is an argument, not a proof. While it's clearly a false analogy in the sense that it doesn't logically imply its conclusion, that's not what we typically mean when talking about false analogies in arguments.
A false analogy used in an *argument*, as opposed to one used in a logical proof, isn't one that "assumes that because two objects share one common quality, they must have another quality in common." After all, by that criterion, all analogies are false analogies. Rather, a false analogy, in an argument, is an analogy where the two objects aren't similar *enough* that you can draw similar conclusions about them. This means that if you want to show that the analogy is a false one, you can't just point out that the two objects are different; you need to be more specific than that.

[edit] The watchmaker analogy before Paley - David Hume
David Hume also used the watch analogy in his work "Dialogues Concerning Natural Religion", from the charactre Cleanthes:
"Throw several pieces of steel together, without shape or form; they will never arrange themselves so as to compose a watch." and "But the ideas in a human mind, we see, by an unknown, inexplicable economy, arrange themselves so as to form the plan of a watch or house. Experience, therefore, proves, that there is an original principle of order in mind, not in matter."
Philosopher Andrew Pyle of Bristol University, states that Paley's Watchmaker analogy is essentially derivative of Cleanthes and simply a convoluted version, nevertheless reaching critical success (Paley's "Natural Theology"). Paley also notes some of the objections to the analogy in his work.
[edit] False analogy
The watchmaker has been called a false analogy because it assumes that because two objects share one common quality, they must have another quality in common.
- A watch is complex
- A watch has a watchmaker
- The universe is also complex
- Therefore the universe has a watchmaker
Critics say that the last step is illogical, because it concludes something that is not supported by the criteria, yet this itself is a false assumption. A false analogy to this argument would be:
- Leaves are complex cellulose structures
- Leaves grow on trees
- Money bills are also complex cellulose structures
- Therefore money grows on trees (which, according to the saying, it doesn't)
This is a false argument and avoids the concept of first causes.
- by several editors
- The missing step in the first sequence is that of comparing the probability of specified complexity forming by random rearragements with the four primary forces compared to the Universal Probability Bound. The second sequence argument is just a spoof. DLH 04:29, 3 October 2006 (UTC)
[edit] Modern Watchmaker Analogy
The proper comparison above to the Watchmaker analogy would more likely be:
- Designers make paper-making machines
- Paper-making machines have quantifiably complex specified structures
- The probability of natural forces forming paper making machines is far smaller than the Universal probability bound (of all rearrangements of the universe over all time.)
To clarify the Watchmaker Analogy in modern terms, propose adding the following example:
- Designers make watches with quantifiably complex specified structures assembled in a quantifiably complex specified order.
- The probability of natural forces forming a watch is far smaller than the Universal probability bound (of all rearrangements of the universe over all time.)
- Self reproducing blue green algae require use of Photosynthesis and ATPsynthase molecular machines
- Photosynthesis and ATPsynthase molecular machines have quantifiably complex specified structures that are assembled in quantifiably complex specified orders.
- The probability of natural forces forming these structures (abiogenesis) is smaller than the Universal probability bound
- Therefore there is a high probability that self reproducing blue green algae were formed by a designer.

[edit] Growing watches from seed
Watches have makers whether they are complex or not. A sundial is a simple kind of watch with no moving parts, but they do not occur naturally, and have to be made. Exceptionally, a suitable living tree might make a sundial if it was positioned on its own and there were suitable hour-stones marking the progress of its shadow. Exceptionally, a naive person might honestly mistake the ticking of a watch for the beating of a heart and conclude that a watch made out of wood or metal was a living thing.
Assuming that the watch that Paley encounters lying on the ground is taken to be a machine, rather than a living thing, the the reason why it has to have a maker and designer has little to do with being complex or not, but rather has to do with whether it is not a living thing or not. Living things can and do make copies of themselves, while machines like watches never do without the help of makers or designers. Watches (with the trival exception of that tree accidentally forming a sundial), never grow on trees or grow from seed.
To summarise:
- if watches are NOT living things, then they must have designers and makers.
- if watches ARE living things, then they need not have designers and makers at least for every generation - living things can make copies of themselves and grow from some kind of seed - this clause does not apply because watches (with the exception of trees acting as sundials) are not living things. Amongst other things, living things can be grown from seeds, or grow on trees or whatever, none of which watches are known to do.
Consider a lifeform such as a horse, which may or may not be complex, depending on how you define complex. A horse has a heart which beats a bit like a watch, and therefore a horse is a machine a bit like that watch.
Repeating our test:
- if horses are NOT living things, then they must have designers and makers, but most people who are not naive accept that horses ARE living things, and thus this clause does not apply.
- if horses ARE living things (and most non-naive people would agree that they are), then they need not have designers and makers at least for every generation - living things can make copies of themselves - note that you cannot prove a negative -
The biggest flaw in Paley's Watchmaker analogy is that he does not consider machines and living things comprehensively, but uses half of one and half of the other. Also, the argument should honestly consider borderline exceptions such as the living tree acting as an accidental sundial. Tabletop

[edit] Gratutitous
GRATUITOUS CONCLUDING SENTENCE:
This article concludes as of 10/29/05 with this erroneous (and tangential) assertion: "Darwin later returned to faith in God and even read scripture to his family on his deathbed."
Darwin's deathbed conversion is an old urban legend based on accounts by his visitor Lady Hope, as per this Wikipedia article:: http://en.wikipedia.org/wiki/Lady_Hope
I recommend the article's final sentence be omitted (and have attempted to remove it...). Thanks, 208.201.231.139 23:21, 29 October 2005 (UTC) Ron Goldthwaite, rogoldthwaite@ucdavis.edu
[edit] Specified complexity; God(s)
Two points.
- The article begins by mentioning specified complexity. While this has some bearing on the watchmaker analogy, this term is a recent invention, and it would be better to re-word to something less specifically from intelligent design (not least to be fair to non-ID creationists).
- Near the start of the article there's a ridiculous section on polytheism. This is possibly in response to earlier remarks on monotheism, but neither has a monopoly on the watchmaker analogy. In fact, if we're to consider ID in its more-secular-than-thou mode, this false dichotomy precludes space aliens.
I object - I find the polytheism argument as cogent as or more cogent than the others, though I find the whole of "Intelligent Design" and the watchmaker analogy to be twaddle. Carrionluggage 22:16, 18 December 2006 (UTC)

Barbara Shack 12:56, 24 December 2005 (UTC)Is this article yet good enough to get it featured? I think its on the way. Lets work to improve it.
TWADDLE is TWADDLE
These kinds of arguments may have been worthwhile in the days of Cicero, or even Descartes, because laboratory equipment was almost nonexistent or, at any rate, much less powerful than today. Charles Darwin was not yet born, nor was Gregor Mendel. In the absence of good laboratories, breeding research (Mendel), or detailed biological and fossil studies (Darwin), it made sense to argue about divine creation of living things within the time periods spanning the Cambrian to the Holocene. Today, it is silly to pursue that - why are not Creationists satisfied to say God made the Universe, with its laws (including Evolution) and perhaps, possibly, started living things on their journey in the pre-Cambrian? The arguments are as useful as those about how many angels can stand on the head of a pin.Carrionluggage 04:26, 22 December 2006 (UTC)

[edit] the retina as "poor design"
hello, my name is Sara, I am a medical student and really enjoyed this article on the watchmaker analogy.
however, I would like to suggest to remove the example of the retina as "poor design" for the following reason:
There is actually a very useful aspect to the way it is designed, although maybe not visible at first. The light sensitive "rods and cones" are directly adjacent to the choroid membrane, because they have to rely on this pigment layer for nutrition and for the constant recycling of their pigments. If the rods and cones were at the forefront of where light hits (which in the article is suggested would be "good design"), there would maybe be no blindspot, but there would be no possibility to recycle the pigments and to obtain enough energy for the retina to function efficiently and continuously.
Also, I think that care should also be applied when concluding from the fact that something can go wrong in a design (like an ectopic pregnancy) that hence the overall design is "poor". It is only a small percentage that "goes wrong", which, even before modern medicine, did not lead to the extinction of the human race. Hence the benefits of such a design to the whole population (if there are any that we may not understand) would clearly have outweighed the risk carried by an individual. After all, the design of cells we would, I believe, agree on is "smart" overall, even though it can go wrong and lead to cancer.
This being said, I think the example of the "false analogy" should definitely be in the main article!! I think nowadays any logically thinking mind would agree that the "watchmaker analogy" is not a sound argument.
best wishes, and great job..

- There is actually a very useful aspect to the way it is designed, although maybe not visible at first. The light sensitive "rods and cones" are directly adjacent to the choroid membrane, because they have to rely on this pigment layer for nutrition and for the constant recycling of their pigments.

- Which is odd, since Cephalopod eyes do have the rods and cones oriented in the opposite direction and their eyes seem to still function perfectly adequately. Hrimfaxi 00:22, 22 May 2006 (UTC)
Hi again. yes, in the cephalopod eyes, the rhabdomeres (which is how their photoreceptors are called, as they are different from and not to be confused with rods and cones...) are indeed towards the outer part of the retina. However, their optic nerve is also extensively simplified, does not contain amacrine, horizontal or bipolar cells. This means that their simplified optic nerve can fit in between the choroid and the photoreceptors, without disturbing nutrition flow. With the human eye, this would not be possible. to place amacrine, horizontal and bipolar cells between the rods/cones and the choroid would make energy supply inefficient.. solution: place the optic nerve on top of the rods/cones, trade some light (without which we can obviously survive and procreate because there is more than enough above the sea...) for more energy supply, and adapt our eye to the inreased "above seawater sunlight radiation". quite "intelligent" actually. so, again, I would argue not to use this example for "poor design". There is a whole section in wikipedia under "poor designs" about that, why not take some that are undisputable? I am only playing devil's advocate here... cheers.
[edit] Complexity
I forget where I read this argument, but the argument was that if you were walking along in an area with a bunch of rocks, you would see rocks of diferent shapes and colors, none of them spherical, or completely one color. But if you saw a spherical rock that was one consistent color you might think that someone had made the rock like that. The point was a spherical rock is actually much simpler than a non spherical rock and the reason why you think something is created is not because it's complex but because it's diffrent than what you naturally see. If People made 10,000,00 pocket watches and made a beach out of them, then the next day you were born you would think that watch beaches were natural and if a rock washed ashore you would think it odd, and that it must have been disigned, not because it's complex, but because it's different. 24.237.198.91 09:45, 4 December 2006 (UTC)
[edit] Watchmaker or Clockmaker
In what way is the watchmaker analogy different from the clockmaker hypothesis? Shouldn't the page of the clockmaker hypothesis be redirected to this site? —The preceding unsigned comment was added by 213.51.106.185 (talk • contribs).
- No it shouldn't. They are unrelated ideas, similar only in name. There is already talk about that on the Clockmaker page. Meggar 01:20, 18 December 2006 (UTC)
