There can be an answer despite I do not know it By Prof Dr Sohail Ansari

   Everything is fated to perish save His Face. (28:88)
Allah! There is no (other) god but He, the Eternally Living, the Maintainer (in charge of all things). Neither slumber nor sleep seizes Him. His is whatsoever in the Heavens and the Earth. Who is that who (Nobody) intercedes in His presence except by His permission? He knows what is between their hands and what is behind them. And they do not surround a thing of His knowledge except whatever He wills. His Chair encompasses the heavens and the Earth, and it does not fatigue Him to preserve both of them (the Heavens and the Earth), and He is the High, the Supreme. (Al-Baqara, 2: 255). 
There can be an answer despite I do not know it.
·        Every scientist is educated enough to know that each discipline is subject to its own assumptions, dimension of analysis, and methodologies; they, therefore should never say religion is wrong because they think monkey is the father of human beings. All they can say is that dogmas are not incontrovertible or there is not a scintilla of truth in them only because they cannot be proved scientifically. Scientists must know that it is ridiculous to say that territory cannot exist if it is not discovered.  

      

Logical consequence (also Entailment) is a fundamental concept in logic, which describes the relationship between statements that holds true when one statement logically follows from one or more statements. A valid logical argument is one in which the conclusions are entailed by the premises, because the conclusions are consequences of the premises.
Syntactic accounts of logical consequence rely on schemes using inference rules. For instance, we can express the logical form of a valid argument as:
All 
  
    
    {\displaystyle A\ }
  
A are B
  
    
    {\displaystyle B\ }
  

 
 
  
  
  
  
  
  
  
  
  
  
  
  
 
 
 
. 
All 
  
    
    {\displaystyle C\ }
  
C are 
  
    
    {\displaystyle A\ }
  
A. 
Therefore, all 
  
    
    {\displaystyle C\ }
  
C are 
  
    
    {\displaystyle B\ }
  
B.
This argument is formally valid, because every instance of arguments constructed using this scheme are valid.
This is in contrast to an argument like "Fred is Mike's brother's son. Therefore Fred is Mike's nephew." Since this argument depends on the meanings of the words "brother", "son", and "nephew", the statement "Fred is Mike's nephew" is a so-called material consequence of "Fred is Mike's brother's son," not a formal consequence. A formal consequence must be true in all cases.

Reductio ad Absurdum

 (also known as: reduce to absurdity)
Description: A mode of argumentation or a form of argument in which a proposition is disproven by following its implications logically to an absurd conclusion.  Arguments which use universals such as, “always”, “never”, “everyone”, “nobody”, etc., are prone to being reduced to absurd conclusions.  The fallacy is in the argument that could be reduced to absurdity -- so in essence, reductio ad absurdum is a technique to expose the fallacy.
Logical Form:
Assume P is true.
From this assumption, deduce that Q is true.
Also deduce that Q is false.
Thus, P implies both Q and not Q (a contradiction, which is necessarily false).
Therefore, P itself must be false.
Example #1:
I am going into surgery tomorrow so please pray for me.  If enough people pray for me, God will protect me from harm and see to it that I have a successful surgery and speedy recovery.
Explanation: We first assume the premise is true: if “enough” people prayed to God for her successful surgery and speedy recovery, then God would make it so.  From this, we can deduce that God responds to popular opinion.  However, if God simply granted prayers based on popularity contests, that would be both unjust and absurd.  Since God cannot be unjust, then he cannot both respond to popularity and not respond to popularity, the claim is absurd, and thus false.
Example #2:
If everyone lived his or her life exactly like Jesus lived his life, the world would be a beautiful place!
Explanation: We first assume the premise is true: if everyone lived his or her life like Jesus lived his, the world would be a beautiful place.  If this were true, we would have 7 billion people on this earth roaming from town to town, living off the charity of others, preaching about God (with nobody listening). Without anyone creating wealth, there would be nobody to get charity from -- there would just be 7 billion people all trying to tell each other about God.  After a few weeks, everyone would eventually starve and die.  This world might be a beautiful place for the vultures and maggots feeding on all the Jesus wannabes, but far from a beautiful world from a human perspective.  Since the world cannot be both a beautiful place and a horrible place, the proposition is false.
In logic, reductio ad absurdum (Latin for "reduction to absurdity"; or argumentum ad absurdum, "argument to absurdity") is a form of argument which attempts either to disprove a statement by showing it inevitably leads to a ridiculous, absurd, or impractical conclusion, or to prove one by showing that if it were not true, the result would be absurd or impossible.
This technique has been used throughout history in both formal mathematical and philosophical reasoning, as well as in debate.
Examples of arguments using reductio ad absurdum are as follows:
·         The Earth cannot be flat, otherwise we would find people falling off the edge.
·         There is no smallest positive rational number, because if there were, then it could be divided by two to get a smaller one.
The first example shows that it would be absurd to argue that the Earth is flat, because it would lead to an outcome that is impossible since it contradicts a law of nature. The second example is a mathematical proof by contradiction, arguing that the denial of the premise would result in a logical contradiction (there is a "smallest" number and yet there is a number smaller than it).[3]

What is the “Reductio ad absurdum” Fallacy?

The Latin term reductio ad absurdum literally translates to, “reduction to the absurd.” In formal logic, the reductio ad absurdum is actually a legitimate argument, but it is often applied fallaciously. The fallacy follows the idea that if the premises of someone’s argument are taken as true, then it necessarily will lead to absurd conclusions.
This is a fairly good fallacy to remember when watching courtroom drama series, as lawyers may try to use this fallacy to show that a witness is lying. For example, a witness could make a claim on the stand, such as, “I know she was driving a blue cars.”
Lawyer: “How do you know this?”
Witness: “Because I’m an interior decorator and I always notice the colors of cars on the road.”
Lawyer: “Oh really? Can you tell us then, when you came to court today, what was the color the car that parked in front of you? To your left? Your right? What was the color of the car that was behind you on the freeway? [etc.]”
The lawyer has just used a reductio ad absurdum in this rather contrived example to show that the witness’s testimony that they “always notice the colors of cars” is very likely to be a false premise because when it is followed to its logical extent (that they would be able to answer the lawyer’s question about every car they saw that day) it is an absurd claim.

Example from UFOlogy

An admittedly contrived example from a UFOlogist could be had in the following statement by them: “If you’re so skeptical that you need to see proof with your own eyes of an alien body before you’ll believe that they exist, then how do you believe in the existence of Paris? Or of a dodo bird? Or an echidna? You’ve never seen them, how do you know they exist?”
The person has just used the reductio ad absurdum fallaciously because they assumed there was only one premise – that I required the proof of the alien body to see with my own eyes. Rather, I would accept other evidence, such as a gazillion verifiable photographs, independent corroboration, real hard evidence that has been examined by the bulk of the scientific community that studies such things and has reached the conclusion that it is real.
For example, the existence of Paris is something that I have seen in books, magazines, and movies. I’ve read about it in history books, my parents have been there, and I’ve met people who claim they come from that city. It has apparently been an integral part of the world’s history for at least a few centuries. To me, that is enough evidence that I can trust that Paris exists.
                                                                                
(This example will actually work with any pseudoscientific field where the skeptic actually wants real hard evidence of the phenomenon, I just happened to apply it to UFOs.)

Final Thoughts


The reductio ad absurdum argument can be used logically so long as one understands what they are doing. The false use of it will usually occur when one assumes a limited initial premise to the claim (in the above example, that I would only “believe it when I see it”).
