Scientific rationalism and its relation with reductionism and physicalism

Abstract

There are mainly two area of research that are considered to resist naturalistic approaches; biology and mind studies. In biology there are two interconnected approaches which claim that the naturalistic approach has failed; Irreducible Complexity and Intelligent Design. The Mind-Body problem, as well, is said to resist the naturalistic viewpoint. I will show that these ideas are just based on the gaps in our scientific approaches that are based on the naturalistic viewpoints. By the light of Gödel Incompleteness Theorems, in this paper I will show that scientific rationalism is mainly based on the gaps that we find in every step of scientific progress; that is to say finding gaps in our scientific explanation is itself a part of its rationality. The notion of the scientific progress also has been defined. In this way we will see that these notions, scientific progress and scientific rationalism, and finally physicalism are going to be defined in a complex system that each one of them is woven to the others. At the end of this article I will show that thinking about the outside world, independent of realistic or idealistic approach to it is woven to naturalistic viewpoint; that is to say we have not any choice other than naturalistic viewpoints.

Introduction

By the light of Gödel’s Incompleteness Theorems (GIT) we know that any formal or symbolic system that is complex at least to the extent of arithmetic is incomplete; this means that we can find some true sentences that we cannot prove. This means that our systems are always open to new and newer changes and modifications. It is not important that these systems are symbolic or not. If they are symbolic or they can be formalized in some ways in a symbolic system then they obey GIT and if not, and they are not symbolized or it seems that they cannot be, at least very soon then we cannot be sure about their completeness. Thus either our systems are open or they are so simple that they cannot inform anything valuable. Henceforth, the system of ideas or beliefs that they cannot be disaffirmed by some methods either are so simple like Propositional Logic that they cannot tell us anything about the world, or they are denying GIT. In what comes in the following I will use this matter to show that scientific rationalism is not based on saying true sentences about the world, but it is to find open discussions and to formalize the scientific knowledge in a way that it is open to the new modifications. Then I will show that Reductionism and Physicalism have this property.

GIT shows us that there are some true sentences which we cannot prove. However, which one of theses sentences are true that they cannot be proved. Maybe when we are using formal systems it is easier to say by the light of semantic rules of the system, though it is not possible always. However, when we are using informal or semi-formal systems the choice is not based on any well-defined algorithm. The only choice that we have, in my point of view, is to suppose that our system is open to new and newer changes. By the light of “NFL’ theorem as has been described by Olle Haggstrom[1] (2007) I infer that Feyerabend is right that there are no defined and exact scientific method, albeit not as strong as it seems now. I will show the limitation of this acceptance in this paper. Then it is very likely that by accepting some propositions as true-but-not-provable ones we enter a contradiction in our system. The most important result that I have inferred from GIT and I will use it in this paper is that: “GIT says that we cannot be sure about the coherency of our formal systems if they are complicated at least to the extent of arithmetic, but it does not entail that we cannot be sure about the coherency of a subsection of the system.” Subsequently we can check every limited subsystem of a symbolic system to find if it is internally coherent or not. In this way by the light of GIT I infer that every complicated system is an open system. Hence it has so many unknown outcomes that we are not aware of, but there is no reason to inform us that it is impossible to discover them. Every proof to show this impossibility is being shaped in an incomplete system; this proof is never complete. Therefore always we can find some logical gaps in this proof. Then we cannot fix our endeavors on these kinds of proofs. Regarding the matter that whether GIT is applicable to non-formal system or not refer to an article of Jonathan P. Seldin that is suggested to be a new research line[2], but as he has permitted himself to suppose that it is applicable at least to philosophy of science in the other article that I have referred to in this essay, I permit myself to apply it for philosophy. At the end of the essay I will present my ideas why I think it is applicable to any non-formal system too.

1-      How the society works?

By the light of Kuhn in his famous work, “The Structure of Scientific Revolution”, we know that scientific discoveries are social activities; hereupon we should know the methods that the society works on individual to know what are the roots of scientific truths.

1-1    Society as a Field.

We can think about society as a field that acts on the individuals as particles. One may ask about the role of the individuals. The same individual has a role when we are evaluating the other individual as a particle; this is the same approach that we have in physical science. In this way the field that an individual is feeling is coming from other individuals[3].

1-2    Human language learning.

Understanding the way that we learn language, I give an example of using the names for colors. Understanding the situation about the colors, suppose the experiment which I have represented below. There are two persons; Jack and Jimmy. We have equipped them with two glasses which have been made by the newest technology. The glasses change the colors of things around us randomly. For example in one of the glasses all the red colors are changed to blue and in the other theses are converted to green, and so on. In the picture below you can see the situation:

The middle pictures that are labeled by some meaningless names are some carts which we have put in front of them. They are watching via the modern glasses which change the colors. For example the red cart is being shown as green for Jack and blue for Jimmy, and so on. Now we have labeled them by new names, for example “Alpo”. We are seeing the Alpo cart as red, Jack as green and Jimmy as blue; but pay attention that when we are doing the experiment we do not know Jack and Jimmy’s perceptions. Now I want to ask a question; have we any problem regarding the colors by the new names? For example if we give them a new hand of carts and ask them to set them as the sample, will we see any contradictions between their sets? Now if they save the new names in their mind and use them to refer to the colors, will they have any problem? Obviously not. If you ask them to give you a Rimi cart both of them will give you a cart that you see as green, Jack sees as blue and Jimmy sees as red. In the Rutledge Encyclopedia of Philosophy under the title of Functionalism we read

Suppose that baby Matthew has an operation performed on his retina at birth which switches the ‘red’ and ‘green’ messages from his retina to his visual cortex: the central physiological state produced in Matthew by red things is thus the state normally produced by green things in other people, and vice versa.

Then we encounter a very important question; what kind of internal state he will have if he is being affected by the red color? In every critique of functionalism we can see this matter. It seems that qualia is like the Achilles’ heel for Functionalism, physicalism, reductionism, and other ideas of these kinds. I will pay attention to the matter in the end of the article. However it seems that it cannot make any difficulties for people. Also in the Rutledge Encyclopedia we find a comparison between Normal people and Matthew’s case, but we can coherently suppose that the mentioned glasses are internalized in our eyes when we born. There is really no such thing as normal or abnormal. It is highly possible that our eyes are working in this way because from the Evolutionary point of view we do not need more than a social language to make a good relation then it is very unlikely to have a common perception of colors, however it is not important. Our society makes a good base for us to have relations. In this way, I think, a holistic viewpoint to understanding and translation is not important at all. We do not make any relation on the basis of internal similarities. Then the society is a bridge from our internal differences to our external relative agreements. In this way society has corporealised the outside world in a social network.

By the light of these realities I want to say that the society that we are living in helps us to make the notions “Intersubjective”; that is not important whether we have internal differences or not. If we can have a language that is strong enough to have a relation with others then we understand each other. In this way common sense is the minimum sphere which all the individuals in the society are agreeing about. For example, waiting behind the stoplight when it is red, waiting in the bus station or going to the cinema and park, going to the shopping center to buy our requirements and so many other practices are in this domain. Consequently the most important role of our society is to make “intersubjective” notions and that we can have good relations based upon them[4]. The stability of our relation depends on the language and the language is going to change because of these relations.

2-      How the science works?

Suppose we want to teach a new student about the notion of “Hardness Coefficient” of a spring. We say to him:

Pick up a spring. Hang it on a base. Pick up a small bulk. Measure its mass by the scale. Convert the outcome to Kg. Multiply the number by 10. Hang it on the spring. Measure the expansion of the spring by a ruler. Convert the outcome number to Meter. Divide the first number by the second. The outcome is the hardness coefficient of the spring. Now if you do the experiment for 10 times and take the average you will have the more exact outcome.

Every scientific notion is established in this way. When you taught him about the spring you can define the other notions by using it. In this way you can use abstract physical notions like “Vector Potential” because it is finally based on intersubjective notions. Everybody knows what a spring is, or a ruler, how they work, and so on. So the scientific notions are based on common sense. Max Tegmark[5] (2003) compares two different viewpoints; frog and bird perspectives .The bird perspective in an outside view which has been gained by mathematician studying, the frog perspective, on the other hand, is an inside perspective of an observer living in the world that is being described by the bird perspective’s mathematical equation. He asks; which one is real? I think –as the same way that he himself has shown implicitly- we use frog perspective to shape our bird perspective, and the bird perspective will convert to frog perspective, and we use it to shape new bird perspectives. Then the reality is being shaped by this relation. If we encounter contradictions somewhere in the frog perspective, our endeavors to overcome it are going to be done by the bird perspective. No one of them is real alone and no one of them is complete; GIT.

Kuhn (1962)[6] compares “the member of a mature scientific community” with “the typical character of Orwell’s 1984” (P.167) and says that they are “the victim of a history rewritten by the powers that be.” Moreover, he says “there are loses as well as gains in scientific revolutions, and scientists tend to be peculiarly blind to the former.” He also compares the methodology of scientific and philosophical education and says “In these fields [Scientific fields] the student relies mainly on textbooks until, in his third or fourth years of graduate work, he begins his own research.” Comparison between “the member of a mature scientific community” and “the typical character of Orwell’s 1984” is seductive, somehow. He compares the scientific evolution with Darwin’s idea of evolution and infers “[w]hat could ‘evolution’, ‘development’, and ‘progress’ mean in the absence of a specific goal?” How has he inferred this outcome? By “[t]he belief that natural selection, resulting from mere competition between organisms for survival… .” (P.172). Daniel C. Dennett (1995)[7] says a very guiding sentence about the progression in the history of evolution: “There aren’t global pathways of progress, but there is incessant local improvement.”(p.308). In the eras of scientific revolution, if there is any, there are some problems which can be solved by the new ones while the old theories are unable to solve. Kuhn’s second condition for new paradigm is “…, the new paradigm must promise to preserve a relatively large part of the concrete problem-solving ability that has occurred to science through its predecessors.” (Kuhn, 1962, p.169) This matter is based on intersubjectivity of scientific notions and it also can be a criterion for progression. The new paradigm has the power to solve more problems. Chhanda Gupta (1993)[8] says

… Objectivity is not intelligible apart from reference to coherent beliefs held by human enquiries, i.e. apart from reference to subject. This coherence and common acceptance in their turn would not be intelligible unless what we commonly accept is really the case.”

 In this way we can see that the objectivity can be saved, though it is not apart from our viewpoint. Thus the new theory has survived in the same way that the survival organism can resist more emergent situations. If the organisms and the scientific theories are competing for survival then the organism or the theory that has survived it can be potentially more progressed, i.e. they can solve more problems. Another condition to complete this potentiality is to have memory to save the successes. The both organisms and scientific theories have this property and according to this criterion we can say that the survival is more progressed. Feyerabend (1989)[9] in the final section of his essay under the title of “Humans as Sculptors of Reality” says:

My point is that consequences are not grounded in an ‘objective’ nature, but come from a complicated interplay between an unknown and relatively pliable material and researchers who affect and are affected and changed by the material which, after all, is the material from which they have been shaped. …The ‘subjective’ side of knowledge, being inextricably interviewed with its material manifestation, cannot be just blown away. (p. 406).

That is why I have used the notion of intersubjectivity instead of objectivity. In this way the society corporealizes the matter in an intersubjective way of research.

Thus, scientific approach is not reliable because it is exact or it is the final and the strictest outcome which we can rely on, but its power is in its “Intersubjective” notions that prepare a common ground for scientific progression.

As I mentioned above, by the light of GIT we know that we cannot reach a complete knowledge system. I infer that always we have some problems in our scientific models and paradigms. The only thing that we can do is to care about contradictions. We should save the internal and external coherency. I think that scientific rationalism is not based on finding some methods to base our criterions for choosing between paradigms or between some competitor scientific theories. If we define scientific rationalism in terms of these matters we will encounter the same problems which we saw in Kuhn, Feyerabend, Davidson and others. However, when we see the rationality as a means to find newer ways to continue the scientific discussions then the problem can be solved. This does not mean that we can decide to choose one of the competitor theories by application of the criterion. I mean that the scientific method always has obeyed and it seems that it will obey this rule. That is why in contrast to any philosophical criticism to some very important approaches in scientific methods scientists are continuing in their own ways. These methods that science cannot ignore are Reductionism and Physicalism.

2-1 Theorem of Research (TOR)

Jonathan P. Seldin (2004)[10] speaks about the relation between Kuhn’s idea about scientific progression and Godel’s incompleteness theorems:

To say that one theory, say T1, is closer to the truth than another, say T2, requires a theory, T´, in which to carry out this reasoning. Since we are dealing with scientific theories, it is reasonable to suppose that T´ would also be ‘strong enough to be interesting,’ and so it would be a mistake to assume completeness for it. This would imply that it would be a mistake to assume that there is a complete definition of truth, and therefore that it is not always possible to say that newer theories are closer to the truth than older ones.

He goes on to say that “Feyerabend then argues that the absence of a sound and complete description of the scientific method means that there is no such method.” I agree with Seldin that Feyerabend’s evidences presented in (Feyerabend, 1975)[11] simply does not support his thesis that ‘anything goes’ in science. If from the absence of a complete criterion to formalize the scientific progression we could infer that there is nothing like progression in science then we could infer that our mathematic and logic are incoherent because we cannot prove that they are coherent. However, we just infer that we cannot formalize them completely, not more. Feyerabend (1981)[12] himself has said that

Incommensurability only shows that scientific discourse which contains detailed and highly sophisticated discussion concerning the comparative advantages of paradigms obeys laws and standards that have little in common with the naïve models that philosopher of science have constructed for that purpose” (p.16)

Perhaps the criterion we were searching for "scientific progression" and "scientific rationalism" is hidden in this disability. Scientific method is a method that is based on “How something can be done?” and not to answer “Why”. To elucidate further, I quote Ray Kurzweil’s book “The Age of Spiritual Machines”[13], where he has used some examples to show that there are some predictions that are false but we have some other predictions that are approximately exact:

"Heavier-than-air flying machines are not possible." -Lord Kelvin, 1895

"The most important fundamental laws and facts of physical science have all been discovered, and these are now so firmly established that the possibility of their ever being supplemented by new discoveries is exceedingly remote." -Albert Abraham Michelson, 1903

"Airplanes have no military value." -Professor Marshal Foch, 1912

"It would appear that we have reached the limits of what is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in five years." -John von Neumann, 1949

"640,000 bytes of memory ought to be enough for anybody." -Bill Gates, 1981

These predictions have been made by some of the cleverest men of science. Kurzweil says

But in looking back at the many predictions I've made over the past twenty years, I will say that I haven't found any that I find particularly embarrassing (except, maybe, for a few early business plans)

to defend his predictions. Even though I think his way of predicting the future of technology as he has represented at the appendix of his book The Singularity Is Near”[14] based on exponential growth of world knowledge is excellent and extraordinary, I think his prediction is more logical than he himself is thinking. According to these failed predictions can we infer that there are some predictions that they fail and maybe sometimes the predictions have won? Is the validity of Kurzweil’s prediction “[a] computer will defeat the human world chess champion around 1998, and we'll think less of chess as a result”, the one which happened with just one year delaying, a chance? According to GIT and by the light of these cases and so many other examples that we have seen in the history of science I infer that we can never say that something is impossible. Scientific method, I think, is like a maze problem solving. You should find a way which conveys you, but not from the beginning to the end, because there is nothing like beginning and especially end, as I will show at the end of this essay, in scientific research. You cannot have the presupposition of impossibility because if you choose this premise then you should stay and to do nothing. We do not need to prove that there is way to exit from the vortex like corridors of the maze to begin our endeavor. However, if we want to stop then we will need a complete proof. By the light of GIT we know that this complete proof is impossible. Aside from this matter, searching for some proofs to show that scientific research is impossible is reducing the “Science” to “Philosophy”; it is in contrast to the ones who are trying for, because they usually are against Reductionism as I will explain later. Then the only choice is to answer just one question; “How something can be done?” There are so many examples of this kind: “How can we reduce chemistry to physics?”, “How can we reduce biology to physics?”, and also a very controversial one “How can we reduce sociology to physics?”, “How can we save the idea of determinism?” I repeat that there is a very deep epistemological difference between two presuppose; “Possibility” and “Impossibility”. The former needs nothing more than the presupposition, but the latter is preventing our movements. We cannot stay because of the role and also the rule of evolution. It is inevitable for us to go on. Every non-developing system will die. We can stay and do not anything, but we cannot stop the events around us. Every system that can develop has the more chance to resist the future catastrophes and it will survive, and every system which does not do this work will be perished. We are not obliged either to move or to stay, but if we stay we will die. Thus we can just see the systems which could choose the best according their own environment, the other ones are died and we have just seen their fossils- in the rocks or in our historical memory. That is why I cannot accept Kuhn’s comparison between “the member of a mature scientific community” and “the typical character of Orwell’s 1984”. The first is based on intersubjectivity but the latter is very suspicious to be based on that. I will discuss about this matter elsewhere.  

Hence, I define the scientific rationalism as: “We should just continue our scientific discussions.” I call this article as “Theorem of Research” (TOR). It tells us “Every time you confronted a dead end, search for a way to by pass it.” By the light of our history I claim that always we will find some possibilities to bypass the dead ends. Why is it that history has evolved in this way? I think the reason for this is because there is nothing to resist against this method; GIT. In the eras of this bypassing we have progression. The resistance against relativity theory, for example, was not based on sectarian division between young and old scientists as Kuhn says, (Kuhn, 1962, P.166)[15] It was based upon the “Twin Paradox” in the system. The acceptance of the theory was not based on substitution of the aged scientists with young ones, but it was based on some advancement that the general relativity gained, mainly in 1919. It is correct that there were other options, such as H. A. Lorentz, but we should not forget that scientific research is a continuous activity. Choosing between the competitor theories is a process that takes time. There were also other evidences in the later scientific activities which supported Einstein theory; for example Hubble's observations that they are being explained nowadays as the expansion of the universe. It is very unlikely that the other options had the same power to support the new observations. That is, if, in those eras, scientists were inclined to accept relativity theory and not other competitors, that was because they were in the process of physical research and they recognized that relativity theory had the more chance to be sustained, though they could not formalize their way of decision making. Furthermore, if they were wrong, and if one of the competitor theories or even a new represented theory could explain the new discovered evidences better than Einstein’s theory no one says that scientists would not choose the more powerful theory and they preferred to adhere to Einstein. The entire happenings in the scientific research are very similar to what has gone in the process of evolution. As the same way that Sean Ekins has quoted Gordon Moore in “Computer Applications in Pharmaceutical Research and Development”[16] “Failures are not something to be avoided. You want them to happen as quickly as you can so you can make progress rapidly”. It is not important which one of the competitor theories will win the competition. After all of the discussions, if all the competitor theories have exactly similar powers let the coin tossing play a role in here. In this situation it is not important which one of them will be chosen. Maybe as Richard Feynman says “Science is like sex. Sometimes something useful comes out, but that is not why we are doing it.” I have quoted this sentence from Gregory J. Feist “Psychology of science”[17] This sentence has something very deep about scientific rationalism, though it is in contrast to its apparent meaning.  This means that the scientific methodology has useful outcomes, but it has not been based on this outcome. In my point of view the main motivation of scientific research is some psychological and cultural motifs as Kuhn has shown, and as Feist has also discussed in his book. However, if it cannot entail to some useful outcome the methodology will fail to be continued. It produces new tools that will alter the production. In this way it produces comfort and it also alters the economical structure. Then it changes the culture of our society. Just suppose that what will be the economical and also cultural effect of free energy. I think that the same goes in the history of evolution of kinds. Every process has happened by physical rules and if we find a trace of chance we should know that all the options in this situation are equal. This means that our scientific methodology is rational because it is in a strong relation with the entire parts of our society.

The structure of our scientific knowledge is not something like a dash line; on the contrary, it is something like a cut line. It has so many gaps. It is not complete and maybe it will never be completed; GIT. But this is not in contrast to rationalism. After Gödel era it can be seen as rationality. Maybe we can say that a methodology is rational if and only if it can speak about its own gaps and also it is obliged to solve the problems with these gaps somehow; albeit by saving coherency. We have no reason to say that these gaps can be filled out completely; GIT. We have no reason to say that we cannot solve every local problem; GIT. We have no reason to say that scientific method is failed; GIT. Even though we cannot formalize the scientific method because of GIT, we cannot show that there is nothing like that, as Feyerabend (1975) has said. All the rational methods are the ones which are obliged to find the gaps and fill them out by restoring the coherency of the system. They are obliged to solve any contradiction as soon as they have been found. In contrast to this rational method every method which claims to be complete is irrational. The scientific rationalism is the idea that we cannot be sure that we have no gaps in our scientific explanation, thus we let the research to remain open; TOE.

Scientific research is something like puzzle solving. However, you have not some erratic pieces. The pieces that should be gathered in a model themselves belong to the social traditions. You do not know what the exact entire shape is. You just pick one; it is not important what the first choice is. You pick the second; it is not important that what the second choice is. You just go on and you will find some pieces which are compatible with each other. Perhaps in the course of your work you will discover that you should modify something in the middle of this picture. Some modification maybe deemed to be a revolution, but it is just a very small change in the picture. Just compare the below pieces:

We can make two pictures:

                                 

These two pictures have been made by the above pieces, but it seems that the second is a revolution if the normal picture is the first. And now if we change the eyes too, then we will see a complete revolution. And then if we change the nose we will see a further revolution as below:

 

This change is the same that Kuhn interprets as paradigm changing. It seems that the two persons from two different paradigms have no common base to discuss each other, but that is not right. Kuhn has shown that cultural and psychological backgrounds are not unrelated to choose between different paradigms, (Kuhn, 1962). However, the same background can be a common base to discuss the different paradigms. The above pictures are being made in the background of the society. There are so many pieces spread out. These pieces are prepared before in the other parts of our human society; from the analogical point of view we can say that they are not spread out garbled in the society, they are indeed a part of other pictures that exist in the cultural sphere of any society.  We just pick them from one place and install them in the other place, but these are the places which we are living in; the society which is nurturing and educating us. It is important to remember that the most important equations in special relativity were discovered by H. A. Lorenz, who was defending a classical interpretation of them. Michelson and Morley had done the famous experiment by a classical background. All of them were carried out in the social background. I think if we cannot formalize the scientific method in a complete system that is just because of its complexity; GIT. However, that does not mean that there is no such thing as scientific approach.

 

3-    Reductionism, Physicalism, and Determinism as scientific rationalism

3-1 Reductionism

I discuss reductionism as the idea that “every phenomenon can be explained by physical laws”. Anti-physicalistic ideas are mainly based upon gaps in our physical interpretations. For some examples you can refer to Chalmers’ “Phenomenal Concepts and the Explanatory Gap”, or Chalmers’ “Consciousness and its Place in Nature”[18] or other works of Chalmers in the endnote, or Behe (Behe, 1996)[19], and also you can refer to Scott A. Minnich and Stephen C. Meyer (2004)[20], and Dembski[21] (1998, 2002), and his other works in endnote. In what follows I will examine three anti-reductionist ideas.

3-1-1 Irreducible complexity

The idea of irreducible complexity is a very strong presupposition. For an example see Michael Behe (1996) and also Minnish and Meyer (2004). Behe uses a mouse trap as an example to show that there are some organisms which cannot have functions without each one of its parts. This approach is flawed for two reasons. At first, it is not important that a mouse trap has not its function, unless it is completed. The function is the sort of things that are important for us and not for the nature itself then if you put aside the teleological interpretation it will not be important that the organism has any function or not, even it is not important that the organism as a whole is dead or alive. There is a way that dead organisms can develop to live ones. Minnish and Meyer in their mentioned essay say that “The data from Y. pestis presented here seems to indicate that loss of one constituent in the system leads to the gradual loss of others.” In the previous sentence they have confessed that “Contrary to popular belief, we have no detailed account for the evolution of any molecular machine.” However, they have resulted in their article that “Molecular machines display a key signature or hallmark of design, namely, irreducible complexity.” The second matter is that the meaning of “Gradual loss of others” in Minnish and Meyer means that we are thinking about the living cell. Let see how it is possible to develop a complete living cell by a very short life-time cells. Suppose the below code.

It is shaped by two different strings, A and B. This is the DNA code of a living cell. Every box is a sequence of Adenine, Temin, Cytosine, and Guanine.  Suppose that it is the DNA code of a very unstable form of a living cell; a DNA-like code[22], maybe. It will die very soon. Additionally, perhaps it cannot duplicate itself. After its death the string will be collapsed from the weakest part that is indicted by a dark line:

Each of these strings can be divided into two strings:

They can make new compounds as below:

And they can shape each one of the below forms:

This schema can show us that it is very natural to think that life can emerge from   non-living matter by passing trough the middle stages as living-like organisms; the organisms which could not duplicate themselves and die very soon. In this way if we accept that the cell organism is reducible to its DNA and its genetic codes then we can find that it can go through the same way that Darwin says in his Origin of species. By using Darwin’s Famous claim in the sixth chapter of his book:

If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find no such case

Behe wants to show that he has found this kind of organism. I refer to Dawkins (1986)[23] for the answer to his claim. According to DNA codes, I say that it is possible for an organism to improve itself step by step in DNA code levels because of biochemical causes. The events in chemical level may be deemed to be an emergent phenomenon in organism levels. I mean that even if we confront a gap in the evolution steps in organisms we cannot suddenly infer that Darwin’s idea is flawed. We do not know so many things about the biochemical realities in the beginning era of life. For example we think that the life forms have emerged after composing of atmosphere. However, it is possible that it can be started before that. If we pay attention that in those eras the measure of background radiation resulting from uranium decaying was more than nowadays; just 3 billions years ago it was 1.75 times the contemporary measure, then it is very natural to think that the probability of mutation was much more than nowadays, especially when we see that these mutations are very easy to occur in simpler strings of the DNA-like codes. There are so many things that we do not know. Reductionism is not the solution as the same way that irreducibility is. I mean if you think that some complexity is not reducible you are not obliged to do more, but if you say that you can reduce something to something else then you are obliged to explain “How”. If an irreductionst is obliged to do more either –as I will show later, he will fall in reductionism or they will produce questions which cannot be answered by science. Such as “Who is the designer and what is the designer's purpose?” This is the idea of TOR that I explained above; you should choose the one which enforces you to do more researches because your system of beliefs is never complete; because of GIT. I do not accept Millstein’s idea [marja be kare montasher nashode ba naqle daqiqe ebarat.] that one can say that we are wasting time. Who can say that what action is time-wasting and what is not, if we remember that it took about 1700 years for us to solve Zeno’s paradoxes, or it took, at least, about 2000 years for us to make an instrument for flying. Just suppose that if we had believed Lord Kevin’s foresight we could not make airplane. Science does not ask that “Is something possible or not?” It also does not hear any person who says that something is impossible. It just asks a question “How it is possible to do something?” There is no example in the history of science that you can find that it has been failed to find a way to complete its mission.   

3-1-2 Intelligent Design

The idea of “intelligent design” is correlated to the idea of “Irreducible Complexity”. As I will show here the idea of intelligent design and its famous tool, “design-detection filter” is based on the strong anti-reductionism and anti-physicalism presupposition. I will survey Dembski’s idea mainly in his famous book The Design Inference: Eliminating Chance through Small Probabilities”. He has spoken about a “Design-Detection Filter” to search for the trace of design in nature. As we understand from his text there are two possible ways for something to be made; chance and design. This idea is based on his way of design detection. He has introduced “Specification” as a strong tool to specify the trace of the designer. By the light of another article of him “Specification: The Pattern That Signifies Intelligence”[24] that is based on clarifying this term and its use, we can understand the strong presupposition. You can find a very beautiful algorithm for design detection in Robert Camp’s piece on skeptic website[25]. In the mentioned diagram you see just “Chance” and “Necessity” and there is no room for laws, physical laws for example. Darwin did not deny the physical laws in the nature and did not say that everything in evolution has happened by chance. Besides this very important connivance of physical laws he has suggested a formula for evaluating the “specification” as the last pace to infer the trace of a designer:

K= –log2[M·N· ϕS(TP(T|H)].

 

However, in this formula we do not have a good criterion to know what ϕS(T) is, that has been identified as “descriptive complexity of T”, where T itself isdescription . However, as I understand his mean mainly via “No Free launch”, T is supposed to be pattern or design. In the article [Specification] he has evaluated this function for the “bacterial flagellum” as “bidirectional rotary motor-driven propeller.” He says
