This is just some ramblings based on views.
I've had a problem with the corpus of facts that people are willing to allow in their arguments lately. These in turn lead to stupid arguments, that lead to my compliants. So here are the complaints.
The first is:
Mankind has been wrong about science for all of recorded history, why are some people assuming that the newest theory is the absolute, final, last word?
Science is a progressive refinement of ideas. There was a time when the public believed that that maggots came from rotting meat and that frogs came from mud around lakes and streams or that they came from rain. Given the corpus of facts that they could work with, those were perfect, scientific beliefs.
The corpus of truth, or the accepted facts at that time [through Europe, at least] included only what could be viewed by the naked eye, and what was accepted by the Church. Since the Church probably didn't have much to say about maggots and rotting meat, it was a simple observation that (1) you had rotting meat, (2) maggots appeard, therefore maggots came from rotting meat. Similarly, (1) While at a pond there were no frogs, (2) It started raining, (3) the area got muddy, (4) frogs appeared. Sure, modern science has pretty much cleared up the origin of maggots and frogs, but it doesn't stop there.
Newtonian physics was around for quite some time, and they have been succeeded by similar equations based on Relativity. These are being further refined today. But these refined models will probably be succeeded in a few decades by yet another model that more accurately describes the Universe, and our current views will be considered 'Wrong'. But that won't mean that Newtonian models will suddenly stop working, or that the Einstienien models will stop working, just that there are more accurate models that can be used.
The point is that our current scientific views should never be taken as the absolute fact of the thing, but just as another iteration that is better than what was there before. Each of these 'facts' is added to our corpus of truth, which helps us better understand the things around us.
This leads to my second complaint,
Some people claim "Religion cannot be demonstrated by Science". That is a stupid argument.
This comes back to the corpus of truth. What are you willing to give me in my corpus? If you give me only the things I can observe with my naked eye and bare hands, I'll prove that maggots come from rotting meat and frogs come from either rain or mud. But with only my bare hands and my naked eyes, I cannot prove cellular theory, or astronomy, or even how reproduction works. If you give me only what can be observed with the naked eye and manipulated with bare hands, it becomes difficult to prove religion.
If you take one simple thing from a mathematician's corpus of truth, let's say the definition of equality or the definitions of addition and subtraction, they will lose all ability to operate. Sure, it is possible to prove addition and subtraction with advanced math, but that math cannot be proven without addition and subtraction. Similarly, if I require proof that a number is always equal to itself, but I refuse to allow any definition of equality, I can destroy all of mathematics.
The point here is that all science is based on postulates. Things that cannot be proven for whatever reason but are accepted as fact anyway. For most people, things that can be directly observed are postulates -- you cannot prove that what you saw is actually what happened, or even that you observed it, but you accept that it is what you observed, and that it is correct.
If you give just enough postulates, those can be expanded to a corpus of truth that can demonstrate the existance of a higher power.
Finally, there are the people who never accept into their corpus of truth anything that contradicts their world-view.
These are the people I most feel sorry for. Yes, there are many things out there that I may disagree with, but I am willing to accept as a theory into my corpus of truth. I may not accept it as a fact, but at the least, I will accept that you accept it. But as is the way with science, contradictions in your corpus of truth must be resolved, or at least marked as 'further research required' before being accepted as fact. When enough evidence is collected to resolve the things to fact, Science is content.
So to the people who assert that Aliens are near Earth, that Alien UFO's abduct people and return them after performing whatever experiments they had in mind, I look at the body of observations that counter them. Air traffic controllers around the world would likely detect such a vessel. Millitaries and governments would quite likely have seen them. Their motion would be seen by astronomers of all kinds, those paid for by governments, by corporations, and by schools, the students and private researchers, and arm-chair scientists. Anything trying to cover it up would be improbable (not impossible).
Of course, I DO beleve in UFO's. They are simply that -- unidentified flying objects. Individuals cannot identify them. Governments deny them, and often for good reason. Many people saw classified aircraft and the governments denied their existance until they unveiled them publically. These were UFO's. Many people have been exposed to (in many cases illigal) radition tests or toxicity tests or other experiments that governments have denied, only to admit to decades later. Yet other things are not easily explained by governments, but by bizzare acts of nature. Lakes turn over, and can even explode. Mists of a dense fog, carbon dioxide, can form naturally and flood towns with death.
While these things may not be easily explained, theories can be developed, and they can be enterered into the Corpus of Truth, to be later accepted or denied.
But now I have looked at my watch, and looked at the time. I don't want to accept the consequences that my Corpus of Truth says I will likely face if I spend more time on this article, so I am finished now.
