“A Preference for Facts”

“A Preference for Facts”         January 26, 2020          Dr. Roger Ray, pastor
“Reality is that which, when you stop believing in it, doesn’t go away.”  Philip K. Dick, writer
When western civilization was emerging in ancient Greece, philosophy and math were not seen as being separate fields. Pythagoras, is someone you will read about in both introductory college philosophy classes and in geometry
Because both are foundational to the study of logic.
So, even in philosophy classes you will see some equations that look rather like algebra.  This might be a good time for me to implore our internet audience to stick with me. You good folks here in the sanctuary are basically trapped, mostly by tradition and good up bringing but it is easier to tune me out on YouTube.
The translation of this equation is “if p then q, and if q then r, therefore, if p then r. A common teaching application of this syllogism is this: the claim that all men are mortal, and Socrates is a man, therefore, Socrates is mortal. 
An aspect of logic that is applied not only in mathematics but becomes crucial to research in all fields of science, is the whole realm of trying to figure out probability.
We all know that when you flip a coin you have a 50-50 chance that it will come up as either heads or tails. However, if you flip a coin 10 times, it will probably come close to being five heads and five tails, but it won’t always be exactly that. But here is the tricky part of logic. If you flip a coin nine times, and all nine times it comes up heads, what are the chances that it will come up heads again on the 10th time? Has the probability gone down to 10% since there have been nine heads in a row? Or 1%?
The fact is that the probability for any coin toss is 50-50 even if the previous 999 tosses had all somehow come up as heads because, men and women, coins have no memory. It may very well “feel” like it should be improbable for it to come up heads a tenth time but, and here is the point, philosophy, math, science, reality, doesn’t care what you feel. And the corollary of that is that theology doesn’t care what you believe. 
The reliability of any logic syllogism is, of course, rooted, in the reliability of the original assumptions. Therein lies the problem of conflict between the world’s religions . . . Christians have tended to believe that in some manner, God wrote the Bible. Muslims have tended to believe that in some manner, God wrote the Quran. If you start with that premise, then you are obviously going to come down to some pretty seriously different conclusions. Of course, if anyone believes that God wrote either one of those books and then you actually read those books seriously, you will likely conclude that God is quite schizophrenic. 
But once you give up on the notion that God writes books, especially particularly self-contradicting, confusing, and largely false books, then you are left with the problem of determining what to believe. Not just the question, “What is true?” but the more nuanced, “What is probably true?” Or, “How likely is it to be true?”
You will have heard either a lawyer or a philosophy professor citing the rule of logic that affirms that you cannot prove a negative. For example:
I might tell you that angels do not exist. In fact, I will tell you that: Angels do not exist. And a traditional person of faith might counter, as they often have, “You don’t know that, you can’t prove that they don’t exist.” Which is true. Unless I have seen everything that exists in all of the universe or multi-verses of speculative existence, if I have not searched every corner of existence, I cannot prove that angels don’t exist. 
However, by that logic, I could claim that unicorns are real. And none of you can prove that they don’t exist for exactly the same reason that I can’t prove that angels don’t exist. So what is reality? Is it just what we like to think?
If reality is based on my likes and dislikes, my personal beliefs and preferences, then angels can be real, and unicorns, elves, dragons, and even King Kong. For that matter there could be a mythically perfect wife or husband, or a perfect presidential candidate . . . all of which are matters of fable and myth.

And for that, we have our old friend, Carl Sagan for saying it very simply. “Extraordinary claims require extraordinary evidence.” It could be true, for example, as some have claimed, that vaccinations cause autism or that wind turbines cause cancer.
However, there is no evidence that links vaccinations to autism and there is lots of evidence that vaccines prevent polio, measles, mumps, and rubella, along with a host of other dangerous childhood diseases. And we know that wind turbines don’t cause cancer because Trump says that they do, and we have a high probability that he is wrong about this because he is typically wrong about everything that he says. That last one is actually what is called an ad hominem fallacy in logic, but I still like saying it . . . and wind turbines don’t cause cancer.
So, the more extraordinary a claim is, the more proof we should reasonably demand for believing it. It may seem impossible that a huge aircraft made of steel and filled with people, fuel, and luggage can actually fly through the air but we have seen it, most of us have been in them, we have studied the physics of air displacement and I have even taken the training to become a pilot and have flown light aircraft across the country. 
It is an extraordinary thing to claim, and yet, in the miracle of modern flight, the evidence is in and none of us have reason to doubt it. We might very well doubt it if just one or two people claimed to have seen it or ridden in one, but we have compelling firsthand evidence. 
So, when it comes to religious beliefs, how do we approach this matter of probability and evidence? It is a vexing problem because, for the most part, the practice of religion is an invitation to assassinate your brains and believe a pre-formed set of beliefs . . . you can be a Jew or a Christian, a Buddhist or a Hindu or a Muslim, and in each instance you can break that down in many ways . . . Christians can be Catholic, Protestant, or Orthodox . . . Protestants can be Baptists, Lutherans, Pentecostals, or about a thousand variations all of the way out to the more bizarre beliefs of Mormons, Jehovah’s Witnesses, and Christian Scientists. 
But what if you don’t want to just accept anyone’s pre-formed package of beliefs? What if you only want to believe what has a high probability of being true? And while there is not an “ap for that” there is a formula that is remarkably helpful.
In the early 18th century there was actually and organization in London, the Fellows of the Royal Society, who discussed matters of philosophy and science, trying to enlarge the body of possible knowledge. A member of the Royal Society, one Thomas Bayes, a Presbyterian minister who was educated in both logic and theology, proposed what we now call Bayes theorem which attempts to put beliefs about probability into a mathematical formula, about which entire courses are taught in grad school . . . so, A person wearing glasses and smiling at the camera

Description automatically generatedyes, it is both beautiful and terribly complex and yet it fits neatly onto a t-shirt, thank you Dr. Jimenez. This formula is used in all manner of scientific research but when we bring it into the realm of theology, we have to assign numerical values to the evidence that we have to support any particular religious assertion of truth. 
I fear that if I wander any deeper into the weeds here that I not only might lose my entire audience but I might become hopelessly lost myself and never find my way home, so let me sum it up this way: the probability that any belief (A) is true, is predicated on the strength of the objective evidence that can be known (B) such that the strength of our conviction about anything should be weighed strictly on the degree of evidence that we have to support the belief. 
Churches have often applauded those who have belief without evidence, in fact, there are passages of scripture that go directly to that point, “blessed are those who believe who have not seen.” I have to object. Believing without seeing leaves one on thin ice, logically, with a sketchy relationship to reality. 
The evidence for the existence of heaven or hell is based on belief with no evidence. There are those who claim to have seen angels but there are those who have claimed to have seen unicorns, the Loch Ness monster, and who claim to have endured a rectal prob on an alien spaceship, but they never have any corroborating evidence. Thousands of people have similarly described near death visions, most of which can be medically explained through oxygen deprivation to the brain coupled with an extremely active imagination and a desperate need for attention. 
The late science fiction writer, Philip Dick, provided our wisdom lesson today. He made his living writing fiction but he was very clear eyed about what is real and what is not. He said: “Reality is that which, when you stop believing in it, doesn’t go away.”  Where now is the first church of Odin? Of Zeus? We decorate our homes with art work and images that reflect ancient Greek religions but we do not venerate those images because the beliefs once associated with them have evaporated. 
Reality, however, doesn’t need a religion to maintain it. The odd thing to me, however, is how religious people will look at facts and just say, “I don’t believe that,” as if reality was determined by whim or personal preference. Try balancing your check book that way and see if your bank is willing to bend through various beliefs about what your checking balance is.
What I am clearly rejecting is the unsubstantiated, if not magical or superstitious aspects of traditional religion but I am still here . . . I’m still a pastor because there are fact based aspects of what it means to be religious that are not only worth living for but, under the right circumstances, are worth dying for.
Where most religious people can find agreement is in the claim that real faith, whether it is Christianity, Islam, Hinduism, Judaism, or Buddhism, is about love and compassion. We can’t reasonably debate the existence of souls, or an afterlife, or angels or demons, but if we are invested in love and compassion, here is what I do know:
About 1 in 5 children in the richest country in the world is growing up in poverty.
There are more than a half a million Americans who are homeless, and about a thousand of those people live within five miles of this church. We have about 50,000 suicides every year in America now and what we know about them is that almost all of those people died because they didn’t feel sufficiently connected to anyone to want to live. All of these churches and all this religion of love, and tens of thousands of people feel so unloved that they take their own lives.  We have about 60,000 deaths from drug over-doses and I’m not sure how many of them would have happened if they felt sufficiently connected to anyone in a loving relationship.
I’m not wanting to blame family members and friends for suicides and over-doses, I’m just saying, for a country that has so much religion based on love, it doesn’t look like there is enough loving going on. Which is why I keep saying that we need to get our spiritual heads out of the clouds . . . we need to stop with the magical thinking and the superstitious stuff that has eaten up so much of our energy, attention, time, and resources, and get seriously invested in what we can demonstrate to be true, real, important and necessary. 
In the past few years we have heard a lot about fake news. And, honestly, there is a lot of what passes for news that is clearly not true or is so spun up into propaganda as to be beneath our dignity. Typically, the way that propaganda works is to tell a lie over and over until, in its repetition, most people will believe that it is true. 
Trump keeps saying that the Russia investigation is all fake, even though 34 people and 3 companies have already been either convicted, indicted, or have pled guilty.
That’s just my opinion but, it if my calculations are correct here, I’m probably right.
