On Time, Space and Being, part two

The last blog post was about how we misinterpret time, it's flow and our existence through that flow. Having established that we do not exist within the confines of time as we think we do, and therefore our ideas about god and the religions that surround him/her/etc... must be mere constructions, we can now turn to the second part of the discussion, matter.
Matter exists. Unlike time, it is a physicality. We are made of matter, the earth, the stars, every molecule and quark is a form of matter. Matter is the stuff, when we talk of stuff. It is easy for us to live our lives knowing this never really giving the issue much thought, but as we do with time and it's flow, when we glance over the underlying structure of matter, we allow ourselves to construct strange pseudo-realities that, while based on the taken-for-granted underlayment of material structure, are nonetheless leaps and bounds outside of sensibilty. I am of course talking about the ideas that we are immortal, that our physical bodies can be ressurected, and go to live, after we die mind you, in a place called heaven, or hell, depending. So let's look a bit closer at that which you and I take for granted in our everyday lives, our bodies.

We can start with our bodies in general. On the surface, they seem to be a marvel of intelligent design. We have all that we need. Fingers for grasping, hands for support and extending the fingers, arms for balance and extention. Toes for precision balance, feet for gross balance, legs for upright stance. A skeleton for internal organ protection and motor movement. Organs for their various functions. You get the point. Our bodies are in an assemblage which allows us the maximum environmental involvement at the macro-level, by having the various organs work in consort with each other. However, our organs and body parts are themselves made of smaller things, without which none would be able to operate, much less provide the services they do. Let's descend to the cellular level. Each of our body parts is composed of a multitude of cells. Each of these cells is tiny, microscopic, invisible to the unaided eye, but there nonetheless. Together, they work in tandem to perform particular functions such as digestion (within the stomach and intestinal lengths), oxygenation (within the circulatory and respiratory systems, via lung cells absorbing oxygen and then transferring it to the red blood cells which co-mingle in the capillaries inside the lungs) and immunization (within the lymph nodes, and white blood cells which help to disengage foreign pathogens and infectants). Each performs it's duty if you will, albeit unbeknownst to itself. A cell has no brain, no thoughts, no ideas. It performs a function that is integral to body as a whole, but that on it's own would be a useless gesture. Our bodies would not live without cells, but the same can not be said for cells. There are many examples of single-celled organisms (yes that is a direct quote from 7th grade biology class, thank you Ms. Pedersen :-)) Cells don't require a larger host organism to operate, but those particular cells in our bodies do a much larger work when combined together. This does not mean the cells in our bodies are more complex necessarily than those single-celled organisms, just more finely-tuned to do particular things. Our bodies are similar to an ant colony in this sense. A colony delegates tasks to individual sections, which when combined together will benefit the whole colony. Of course, cells themselves are comprised of smaller entities, namely molecules.
Since our cells do not have individual brains, then it stands to reason that individual molecules also lack them (especially considering a brain is an organ comprised of cells, which are in turn composed of molecules). Molecules make up everything larger than themselves. Up until now, we have been reducing gross matter to ever smaller constituents. At the molecular level we begin to see matter for what it really is. Molecules are the last step we take before we encounter that which comprises all in the universe we know of. Molecules make up cells (again, thanks to 7th grade biology) but they also make up everything else; water, rocks, air, fire. Although we are bodies, we are more primitively organs, and before that we are cells, and before that we are molecules. So in this sense we are no more than that which surrounds us, living or not (we will come back to what we are).
I'd like to return for a moment to the level of our bodies and discuss solidity. Feel your arm. Go ahead, feel it, touch it. Does your hand go through your arm? No of course not. Why not? Because your arm is covered in skin, filled with bone and muscle. It is solid. So is the chair you are sitting in while reading this, right? Well, I can't push right through my arm with my finger, so there is a bit of solidity involved here, but what about the cellular level. Cellular walls are readily punctured, this is how infection occurs. And since we are made of cells, aren't we not as solid as we think we are? How about the molecular level? Well, molecules are comprised of atoms, which are the singular manifestations of the elements which make up all of the matter in the universe. These atoms are in constant flux, meaning they bombard each other constantly, knocking some molecules awry and replacing the displaced atoms with themselves, thus changing the molecule itself. Molecules are atoms attached to each other via electron-compatability. This means that two hydrogen atoms and one oxygen atom will attach together because the number of electrons balances and leaves a stable molecular configuration. There is a lot of space in between the specific atoms of a molecule. Molecules are mostly made of empty space; electrons orbiting the nucleus, which is made of protons and neutrons. The molecules which make up the chair you are sitting in disallow you from falling through them by repelling you (specifically the molecules of the cells in the skin which covers your butt). The solidity you feel is simply the electro-magnetic repulsion from billions of molecules pushing against each other.
Just as review, because we descended pretty quickly there: Molecules are made of atoms, atoms are made of protons, neutrons and electrons. Each descent takes us an order of magnitude smaller. While there is very little solid space inside a molecule, there is even less solidity inside an atom. Almost 99% of an atom is empty space. And whatever taken-up space there is so little as to be almost non-existant. And it doesn't stop there. Protons and neutrons are themselves composed of smaller particles (elementary particles) called quarks. Electrons are themselves elementary particles and are thus not composed of quarks. The space between quarks is even more ridiculously wide-spread. The only thing holding protons together are gluons (these are force-carrying particles, which transmit the strong nuclear force, which is what holds the protons and neutrons together). We are made of organs and there is space between these organs. Our organs are made of cells and there is even more space between these cells. Our cells are made of molecules, of which the space between widens fantastically. Our molecules are made of atoms which are held together by the stability created between the balanced number of electrons (nothing else), and the space between the atoms in a molecule is also immense. Our atoms are composed of protons, neutrons and electrons, where 99% of the space is empty. Our protons and neutrons are made of quarks, which are also almost completely empty.
On the sub-atomic level, we are comprised more than 99% of empty space! I'll say that again. On the sub-atomic level, on top of which all other components of ourselves are built, we are mostly empty space. This is as reductionist as you can get. reduce everything down to the most basic level and there is really nothing there, well almost.
As in the earlier post about time, this true nature of matter and how we are composed, makes it easy to see that all of humanity's endeavors are constructed as a house of cards. From politics, to religion, everything we think, we think from an assumptive standpoint. Since this particular blog is meant to derail religion, let's stay there. Religion says we are more than are parts. There is something that is non-physical about us. Religion would say of my deconstruction above that it is valid but irrelevant, because that which makes us is not part of the physical world, but rather the supernatural one. This is a stance that can be easily taken when one looks no further than the conglomeration which is our natural physical body. Like a person who listens to a piece of music and finds more than just the note patterns, the religious person looks at his/her body and finds more to it than what is there.
This can be done because the religious person assumes that the consort that the body works inside of is something that is greater than what the individual parts would be capable of. The complexity we see at our level is assumed to be an impossibilty for smaller much simpler component parts. This is the moment of truth, for it is here that the assumption leads some astray. The assumption is this: Complexity cannot arise out of simplicity. This is wrong. Complexity is the result of the layering and interweaving of simplicity. It can and only does arise from simplicity. Elementary particles are just that, the most fundamental constituent odf the known universe. when combined, they create a slightly more complex entity, the atom. There is no intelligence governing this intermingling, it is simply random in nature. But remember it is the intermingling that is random, not the coagulation. When combinations are made, it is because the combination is more stable than either previous singularity (not in the sense of the big-bang singularity). So the combination is purposeful, the purpose being a more stable configuration.
when simple atoms combine to form slightly more complex molecules, the process of intermingling is random but again the connection eventually made is not, nor is it intelligent. There is no decision made, nor recognition made that stability has been achieved. It is only that there are stable configurations and there are unstable configurations, those which are unstable break apart for obvious reasons and those which are stable stay together for obvious reasons.
When atoms combine to form molecules, they combine in a multitude of ways, one of which is DNA. The DNA molecule is a stable molecule, one which is also self-replicating. It is only a molecule, but by copying itself, it quickly gives rise to larger, more complex colonies which we call cells, which then give rise to our organs, also many times more complex, and so on. The complexity which we see sits atop the simplicity we can't. This blindness, which existed for millenia before the advent of molecular discovery and study, is what allowed religions to so fervently take hold of the human mind. Religion only exists as a remnant of the ignorance humankind lived with for so long. It serves no purpose beyond artificial comfort and dread. It lies as a testament to the need for further inquiry into the foundations of our world, because without this inquiry, assumptive practices can and most likely will destroy us. Next up, Location.

On Inductive versus Deductive reasoning

Since "coming out" to my family in January about my atheism, I've had a few debates with them and others about christianity versus atheism. Just the other day, two Jehovah's witness ladies came to my door, wanting to innocuously know if I believed the bible had a prophetic nature. They had no idea what they were in store for. It was a pleasant discussion, but ultimately one that had very little effect on either parties involved. A few months ago, I posed an email question to one of my long-distance friendly adversaries that said "What of science, do you accept?" They said, " I accept any claim of science reached through deductive reasoning. I disregard anything concluded as a result of inductive reasoning" This person categorized evolution as a postulate arrived at through inductive reasoning. This is interesting. Inductive reasoning (bad, for scientific truth), deductive reasoning (good, for scientific truth). My friend doesn't think evolution has occured, they think we were modeled out of dirt by the hand of god, 6,000 or so years ago, in our current form, as was everything on the earth (maybe not necessarily out of dirt, per se). They also give as one reason for their unacceptance of evolution, the statement that evolution was arrived at through inductive reasoning, not deductive reasoning.

Webster's dictionary:
induction: inference of a generalized conclusion from particular instances.
deduction: inference in which the conclusion about particulars follows necessarily from general or universal premises.

Please take a moment to look at the difference between the two definitions.

To induce that something is the case, you must begin with a set of particulars, from which you can then extrapolate a more complex and wider idea. The beginning is the details.

To deduce that something is the case, you must begin with a general or universal premises, from which you can then conclude that the particular, observable micro details are direct results.

My friend doesn't accept evolution because it begins with a set of particular observations about nature a: extinction, through the observable particular of fossil remains, b: genetic mutation, through the observable particular of both laboratory DNA experiments and natural adaptive attributes of different species. My friend doesn't accept evolution, because it then proceeds with these particulars to expand a more widely-encompassing set of explanations, which arebased on the little details already observed. My friend DOES NOT ACCEPT evolution because of this.
But, my friend, accepts most everything else they encounter in life which employs the exact same process.
Take breakfast, my friend decides to have breakfast after having taken inventory of the particulars of their pantry. They start with the details. They then induce that breakfast is a possibility, so hunger and energy will dissipate and increase respectively, extrapolations based on detailed information gathered. My friend accepts inductive reasoning when it comes to breakfast being helpful, but does not accept inductive reasoning in regards to evolution. What else do they contradict themselves with? Well, how about travel? My friend goes to work each work day, and I presume they employ some method of transit to facilitate this trip, either individual car, mass transit system, paddleboat, something. Well, how do they do this. Do they begin with the universal premises that travel is a possibility? Yes and No. Yes, in that, to the short-lived human individual, confined to the particulars of past discovery, it is inevitable that to my friend, it seems a universal premises that traveling fast via non-human means is a real possibility. However, that universality is only seemingly so. The wheel was undiscovered at one point in our history, albeit well before I or my friend lived. My friend and I both enjoy the benefits of the wheel, but the wheel was at one point, an observable particular of the environment. Using this observable particular, our ancestors extrapolated that this arc-edged implement could be used to speed things up for them, and the rest is history. So in this way, the answer is no. My friend as a human being, can never begin, at the real beginning with a universal premise that faster travel is possible, they must always and forever be grateful for the particulars discovered by their distant ancestors.

Inductive reasoning is validly accepted as a way of discovering scientific descriptions of our world. Evolution could only ever have been the result of inductive reasoning, and rightfully so, that is exactly what makes it make sense. It started with details, and Darwin induced from those details that something more fundamental and unseen to the incurious, was going on.

But what about deductive reasoning? The taking of a universal premise and gathering the observed details underneath the umbrella. This is a different approach, and certainly not one that scientists regularly employ. Particle physicists sometimes employ this method, because without such a method, the unobservably small constituents they are concerned with would never have been postulated to begin with. Elementary particle such as quarks, leptons, and electrons don't leave tell-tale signs for the laymen to see, which is how each of them remained unpostulated for so very long. However, the only other arena which regularly utilizes deduction is that of religion. It makes sense to me, that my friend, a fundamentalist, southern christian conservative, would accept deduction but not induction, because religion starts with the universal premise that god exists. It then gathers under that assumption, the ideas that we are his creation and we are sinful by nature. The evidence gathered under the umbrella is done so after the macro-assumptions are made. The bible is one of the particular evidences of the truth of christianity, as is the idea of our possession of self-awareness. These two particulars of evidence are assimilated into the general idea that god exists, only after the the premise has been both postulated and accepted. This is the nature of deductive reasoning. So according to my friend's logic, they can willingly accept the inexact theories of string theory, the multiverse, and both quantum mechanics and special and general relativity (which few non physicists really understand), but they can't accept that breakfast might fend off hunger and increase productivity.
All of this is prelude to the real subject of this blog, and that is this:

If christianity were truly true, then christians should have been able to arrive at their belief system wholly divorced of the bible. Now doesn't that contradict the entire preceding section? Didn't I just get finished saying my friend arrived at their belief because of deductive reasoning? While that is true, it doesn't really counter what I've already said. Again, If christianity were really true, then evidence other than the bible should support it's claims. Christians have only the bible as external evidence that what they claims is true is so. Without the bible, for the last 4,000 years (torah and later the new testament) what grounds would the christian church have had with which to not only survive, but to flourish as it has? I say, the christian has only the bible as an external source of evidence, but what about the recognition we all have of ourselves, our self-awareness? That is not an external source of evidence but an internal one, something that is confined to the individual and cannot be rightfully used to gauge the truth of a social trend such as a particular religion. Social truths (memes) as religions claim to be, can only be found to be as such, if A: they are the result of individual(s) within the population coming to exactly the same conclusions time and again throughout the entire course of the population's existence (species), and B: if there is indeed an all-powerful controlling entity which actively participates in the lives of the individuals in such a way as to ensure that such social decisions are being arrived at. However, such a discovery is not possible, because it pits inductive reasoning against deductive reasoning. Remember inductive reasoning involves starting with the particulars and ending with the big picture, while deductive reasoning starts with the big picture and fits the details into that big picture. The problem with trying to affirm or deny god's existence by evaluating the testimonial truth of self-awareness as internal evidence, is that it requires that we start with inductive reasoning, the details being the observable, comprehensive and macro-social behaviours of the species, and the resulting arrival at the same behavioral conclusions, all of which will result in the big picture of god existing as the controller of this drama; and, it simultaneously requires that we begin with deductive reasoning: assume there is an all-powerful, active participant in our social lives, having endowed us with self-awarness, thereby granting us the ability to construct social lives, whose further activities center around ensuring our arrival at a universal set of behavioral conclusions. We must start with the big picture of god absorb all the details into this as to make them fit with our preconception. we must deduce that the details are the result of god's being in existence, but we must also induce that god exists because of the myriad of details which poin to that conclusion. This is circular. You can not have both inductive and deductive reasoning at play at the same time.
Rest assured, I am by no means suggesting that humanity, in all it's societies has actually resulted in the same universal morals, as such a discussion would require. It is painfully obvious that we as a species have exhibited throughout our history a deplorable lack of compassion for our fellow man. Genocide's existence testifies to our incapability of agreement on the universal sanctity of life, So does slavery. For that matter, all violence testifies to the one thing that makes humanity the same, we are animals. Our self-congratulatory religions might feign to celebrate the simultaneous prestige and disdain of humanity, but our behaviours illuminate our animalistic nature much more so. I suggested that christianity should have some other source of external evidence with which to support it's claims. Here are a few suggestions:
Let's see some literal stars fall to the ground (impossible since stars are bigger and hotter than the earth, and so would burn us up without being able to "touch" the ground): Mark 13:21-25.
Let's hear some mountains sing about how good god is (again impossible since sounds must utilize vibrations and mountain cannot be simultaneously the source and agent of vibrations, not to mention what language the mountains would sins in ): Isaiah 55:12
Or how about some rocks crying out: Luke 19:40.
How I'd love to see a big-ol mouth open up on Teddy Roosevelt's face at Mt. Rushmore and hear him start singing the hallelujah chorus....
There is no evidence away from the bible, for the christian to believe in christianity. Without this, it is impossible to validate the truth of christianity's claims, therefore, without taking anything else into account, the best christianity can do at this point is acknowledge that it is severely deficient in it's case for the ultimate in truth. But we must take into account many other things, for instance: a: The existence of rival religions, some of whom make almost identical claims using almost identical sources of "evidence", b: The existence of secular explanations for the issues religions concern themselves with; life, thought, feelings, etc...
When these alternative explanations are taken into account, the christians case slides from being severely deficient, to that of one of maliciously outright deceipt. It is no excuse for the christian to assert that their belief system has brought comfort to anyone, much less many billions of people over the years. Comfort with an idea is not a way of validating it's truth. I may be very comfortable with not working a day in my life, but that is no reason to believe that not working a day in my life is how I should spend my existence. It might be very comfortable for me to simply ignore the cries of my child, because I'm tired, but that doesn't mean that my child isn't hungry, just because I am more comfortable thinking that if I wait long enough, he will stop being hungry and stop bothering me. Comfort is a not only an invalid excuse it is a deplorable one. The truth of existence, will only ever be discovered, it will not be nor has it been revealed, not in the manner which religions speak of.
Christians: you have no acceptable reason to say the things you say, you have no honor in speaking of things about which you've never invested any amount of effort in trying to disprove, and you have no sympathy from those of us who recognize your false humility.
Atheists: you have a responsibility to call out your lazy religious friends and make them confront what they say they believe, but do so in a nice way, so as to make them sure that you're confrontation is a plea for reason and not an attack on a personal level.
Scientists: You have a responsibility to do your jobs, continue collecting the data, and inducing from your data, larger more encompassing explanations of our world. It is to you who the world looks for it's answers, despite what the world might say to the contrary. It is widely accepted that cars will work, we base our transitive lives around this fact, but I'm unaware of any church official who beat Henry Ford to the punch and invented the automobile before he did. Science is what we need, not religion. Keep up the work.
