Earlier this morning, Fr. Duncan (+Dunk) responded to daveb who had made the point in a comment that nobody knows how the image was formed (see I agree. I agree. I agree. Mostly.). He wrote:
In one form or another it is the most used argument for the Holy Shroud’s authenticity: nobody knows how the image was formed therefore it is real.
Well, hmm! I would probably say, since we are talking about authenticity, nobody knows how the image was forged or faked or artistically created. And then yes, I would agree, the argument is used frequently. Philosophically, I don’t like it. We are voicing classic Argumentum ad Ignorantiam (argument from ignorance). Nonetheless, I find myself using the argument with the shroud. It seems true.
In 1963, John Walsh wrote:
The Shroud of Turin is either the most awesome and instructive relic of Christ in existence…or it is one of the most ingenious, most unbelievably clever products of the human mind and hand on record…it is either one or the other, there is no middle ground.
And we weren’t clever enough to figure out how it might have been manmade so many of us found ourselves agreeing it was real. We still do. Can such logic be defended? Stephen Jones is one of the few people to tackle this question and he has done so very effectively. In a posting, Shroud of Turin News, October 2013. Stephen began by quoting Jonathan Pitts of The Baltimore Sun saying:
To believers, the Shroud of Turin, as it’s known, is the cloth that cloaked the body of Jesus before his planned burial. To skeptics, it’s a hoax conjured up to sell Christianity or draw tourists.
And then responding:
The “skeptics” (who are themselves “believers” in the Shroud’s non-authenticity) have no evidence that the Shroud was “a hoax conjured up to sell Christianity or draw tourists”. They cannot cogently explain: Who conjured it up? How was it conjured up? When was it conjured up? Why can’t they conjured it up (i.e. make a convincing replicate copy of the whole Shroud)? The “skeptics” (so-called) cannot even agree on how the Shroud was “conjured up”. As Ian Wilson concluded after reviewing all the major sceptical theories of how the Shroud was forged:
“Yet ingenious as so many of these ideas are, the plain fact is that they are extremely varied and from not one of them has come sufficient of a groundswell of support to suggest that it truly convincingly might hold the key to how the Shroud was forged – if indeed it was forged.” (Wilson, I., “The Blood and the Shroud,” 1998, p.10-11).
Quoting Pitts again:
It has been studied by everyone from theologians to NASA historians, and still, no one knows. “The shroud is the most analyzed artifact in history, yet it’s still the world’s greatest unsolved mystery,”
Stephen follows through with:
This alone is effectively proof that the Shroud is authentic. It is an important qualification of the usual “argument from ignorance”, that if something should have been discovered by qualified investigators but hasn’t been, that “absence of proof of its occurrence” is “positive proof of its non-occurrence”:
“Argumentum ad Ignorantiam (argument from ignorance)… A qualification should be made at this point. In some circumstances it can safely be assumed that if a certain event had occurred, evidence for it would have been discovered by qualified investigators. In such a case it is perfectly reasonable to take the absence of proof of its occurrence as positive proof of its nonoccurrence. Of course, the proof here is not based on ignorance but on our knowledge that if it had occurred it would be known. For example, if a serious security investigation fails to unearth any evidence that Mr. X is a foreign agent, it would be wrong to conclude that their research has left us ignorant. It has rather established that Mr. X is not one. Failure to draw such conclusions is the other side of the bad coin of innuendo, as when one says of a man that there is `no proof’ that he is a scoundrel. In some cases not to draw a conclusion is as much a breach of correct reasoning as it would be to draw a mistaken conclusion.” (Copi, I.M., “Introduction to Logic,” 1986, pp.94-95. Emphasis original).
Stephen then concludes:
Similarly, if the Shroud were a 14th century or earlier fake, the science of the 20th-21st century should have discovered that by now (see below on the 1988 radiocarbon date of the Shroud to 1260-1390 is itself a fake!). So that absence of proof by modern science that the Shroud is a fake, after 35 plus years of intensive scientific study of the Shroud, is positive proof that the Shroud is not a fake!
Okay. That is unless we missed something. How do you evaluate that possibility?
That is all fine and good until argument from ignorance logic turns into a building foundation:
Myra Adams, in a recent article, Jesus `most significant person ever’ in new research study, (and see my posting, How the Shroud Becomes Part of the Conversation) stated:
. . . that is why [=Jesus’ significance] the mysterious Shroud, which could prove Christ’s physical resurrection – the foundation of Christianity, is still an open and active cause célèbre among believers in Jesus’ divinity and members of the scientific community who continue to study the Shroud and remain intrigued by its unique properties.
which resulted in a swift and direct reaction from Stephen:
The Shroud of Turin already has proved, beyond reasonable doubt, Christ’s physical resurrection and therefore that Christianity is true. But that does not mean that that proof cannot continue to be unreasonably denied, by those (including some Christians) who don’t like the implications of there being scientific proof that Christianity is true.
So am I a denier? And, apparently, I don’t like the implications of there being scientific proof that Christianity is true? Has a weak argument from ignorance become the basis for saying that we have “scientific proof that Christianity is true?”
Fear the person who has no doubt. Witness George Armstrong Custer.
