Converting Nerve Impulses to Muscle Stimulation

berticus says...

@jonny also sifted this.
>> ^L0cky:

Upvoted, but to be honest they could have been making all that up for all I know.
Also I'm surprised by the amount of steps and chemical reactions considering the response time between thinking and doing. Did anyone share my naive imagining of magical electricity shooting from my brain and contracting my muscles?
What I'd find interesting is learning how nerve impulses (also known as action potentials!) form, or begin. How they get from or are cued from this seemingly virtual world of my thoughts into actual things that do stuff to my body.

Essentially you have a branching network of fibers (dendrites) that join together at the neuron (brain cell) body. If enough of these dendrites stimulate the neuron body then the neuron sends the action potential, if there is not enough stimulation, then no action potential is sent. So while a neuron can be activated in a variety of ways (e.g dendrites coming from various areas of the brain) there is only one outcome - either the action potential is sent or it isn't.

Movement is a lot more interesting than just thought - action potential - movement, however. This is because parts of our brain can store movement patterns, so many of our learned movements (e.g. dancing) just need a trigger and then some movement pattern is initiated at a sub-conscious level - the cerebellum is a part of the brain that helps with this.

@L0cky - I was worried the jargon would be a bit too much. The video definitely assumes knowledge of certain physiology concepts. I'd be happy to explain as much of that as you like. But I'm not sure if you're asking about the basic biology, or something more metaphysical in the sense of how conscious thought is transformed into patterns of neural activation.

As for the speed of the process, keep in mind that this is at a molecular scale. This is all happening at the speed of very tightly coordinated chemical reactions.

Stephen Colbert interviews Neil DeGrasse Tyson

Well, let's talk about rationality for a minute, since you seem to be a logical person. I just don't think there is any basis in a secular worldview for rationality. For instance, if you believe in evolution then you believe that life came from non-life, which means that your rationality came from irrational forces. How can you trust it? If you have inherited your reasoning capability from rocks and primates, how is it trustworthy?

Another question is, how do you have any free will in a secular worldview? If the way things are at this moment is due to the arrangement of atoms at the beginning of the Universe, then there is no such thing as free will. Those atoms have you locked in from birth to death and no one has any meaningful awareness. There is no way to get outside this box that materialism puts you in. How do you respond to this quote:

If there is no God, then all that exists is time and chance acting on matter. If this is true then the difference between your thoughts and mine correspond to the difference between shaking up a bottle of Mountain Dew and a bottle of Dr. Pepper. You simply fizz atheistically and I fizz theistically. This means that you do not hold to atheism because it is true , but rather because of a series of chemical reactions… … Morality, tragedy, and sorrow are equally evanescent. They are all empty sensations created by the chemical reactions of the brain, in turn created by too much pizza the night before. If there is no God, then all abstractions are chemical epiphenomena, like swamp gas over fetid water. This means that we have no reason for assigning truth and falsity to the chemical fizz we call reasoning or right and wrong to the irrational reaction we call morality. If no God, mankind is a set of bi-pedal carbon units of mostly water. And nothing else.

Douglas Wilson

Since you mentioned that you work with math, where do you find the laws of logic in nature? How do you presuppose something which is unchanging and immaterial in a Universe which is material and always changing? I can account for these things in a theistic worldview, so how do you account for them?

I can relate to tyson, as I felt the same feelings when i was a kid..started reading cosmos at age 4, went to planetariums, got a telescope, devoured any and all information i could get my hands on about astronomy. I can relate to his sheer sense of wonderment about it. What I find interesting though is how he talks about having a personal relationship with the Universe, that it talks to him, that it was "calling" him, and how the Universe (as starstuff) is within him. That is unmistakably worship.

Indeed, this video talks much about the irrational kinds of religious orders secular people still hold to, like love or living forever. People, even those who claim to be rational, still deal with our monkey nature more oft then they would like to admit to themselves <IMG class=smiley src="http://cdn.videosift.com/cdm/emoticon/teeth.gif">

The Religious Mind Is Morally Compromised: Demonstration

shinyblurry says...

I appreciate your comment because it shows thoughtful people on the sift what you, and people who think like you, are all about. It shows the facism inherent in your idealogy. It sounds like you'd fit right into the communist regimes of the 20th century.

As far as your claim on genetics goes, I find it ironic because your faith in materialism and evolution demands that your thoughts and beliefs are the result of unconscious processes and chemical reactions in your brain. In this view, your militant antitheism was decided by the arrangement of atoms at the beginning of the Universe. You inherited your reason from unreasoning animals, and your so called rationality is determined by irrational forces, IE, it is untrustworthy and should be discarded.

>> ^SpaceGirlSpiff:
Why do you all still argue with Shiny? I've said it before and am saying it again. You are wasting your time. Shiny has no capacity to change his mind based on reason, logic or rational evidence. You may as well spend your time trying to convince a dog to change the color of its hair.
You will cite reason, logic and rationality... he will cite dogma. Rinse, repeat.
He is most certainly one of those who is genetically predisposed to be religious (http://www.nytimes.com/2009/11/15/weekinreview/12wade.html) and cannot help thinking the way he does. I would pity him if he and those that think like him did not pose such a threat to the civilized world.
He is a lost cause, but there are others who can be "saved" and brought to see reason. I suggest you find those and spend your time helping them instead.
You are better off ignoring him. Let his dogma go unnoticed and starve him of attention. Let his dogma die of starvation and fade into the past.

A mind created and designed it, therefore a mind is involved, therefore it is an invalid example..


So, by this argument, if we live in a deist universe, in which the universe was created but the creator pays it no mind, then abiogenesis and evolution by natural selection are completely plausible. That's an interesting position, it does not really help you here.

>> ^shinyblurry:

Abiogenesis is unproven because there is no evidence, it is just metaphysics. It's your faith that it is true. It is not the only coherent explanation, it is just the explanation that you have to believe because you have ruled out an intelligent designer apriori.


You seem to not understand the meaning of apriori. A few hundred years ago everybody in the western world, at least claimed to, believe the creation myth of genesis. We got to here from there, don't pretend your ideology has not had a chance, you were in charge of the game, we called your bluff, you just had nothing in your hand, you still don't.

Evolving molecules exist, they came into being at some point after it was possible for them to exist in this universe. The only non-magic hypotheses we have are based on a naturalistic model where these molecules are generated by a series of non-evolving processes. The gaps in the chemical record are very much like the gaps in the fossil record used to be, we have not filled them all, but neither have we found one that can not be crossed, and no reason to think they will not be filled.

Here is the hypothesis


The ID position is stated there in four parts, the last three follow from common decent, and the first one is either false, like all Behe's examples, or undemonstrated. It is mathematically possible that there is irreducible complexity somewhere, just as with faeries and unicorns, absence of evidence is not evidence of existence.

All the Discovery Institute links were painful in their fail. DI is a propaganda organization, only one of their links discusses any scientific discovery, and it actually makes no ID claims. The rest of the articles either make no claim, or have been shown to be false. If Well's article is going to be your flagship falsifiable ID position, fine, but you should probably know it's already been falsified here .

>> ^shinyblurry:

There is obviously a concrete difference since life doesn't come from non-life, and has never once been observed doing so. You have everything in the world to prove here.


This is your premise, and your conclusion, draw the line, and I will show you something on either side that confounds your "distinction". If you can't define the problem, I can't show it's flaws. Refusing to define your terms may get you by in theology, we are talking chemistry here, chemistry does not "work in mysterious ways".

>> ^shinyblurry:

if our mental processes are just chemical reactions, then there is no reason to believe anything is true. If our mental states have their origin in non-rational causes, rationality can't be trusted. You can't know if the rationality we have from evolutionary processes is discerning the truth of the world or not.


Ontology can't help you here, gods, since the can intervene, make it more difficult to make truth claims, not easier.

>> ^shinyblurry:

The reason it is labeled magic is because there is no proof.


There is no proof of anything. There is evidence of RNA/DNA metabolism, there is evidence of general chemical probability, there is no evidence for irreducible complexity, or anticipatory design in any non lab built genome. You can scream about nonexistent, and unneeded proof all day, science follows the evidence.

RSA Animate - The Divided Brain

Skeeve says...

The point is that his experience contradicts everything which is taught in this video. By all accounts he lived a normal life, with feelings and relationships and struggles, but did not have anything approximating the brain structure described in this video. Clearly you can see much that is being spouted here is just a materialists wet dream. The attempt to approximate all human experience into mechanistic terms.

No, Dandy-Walker does not contradict everything taught in the video. He has (and others like him have) most of the same brain structures (especially the ones related to consciousness). For the most part, they are missing their cerebellar vermis, which controls and analyzes spatial motion. The parts that have something to do with consciousness are still there, and they are even in pretty much the same place as they would be otherwise.

Even if the parts of their brain were jumbled up a bit, that doesn't mean they couldn't necessarily have consciousness. The body does some amazing things considering some of the biological errors that happen. People can be born with holes in their hearts, or on the wrong side of their body, and have perfectly functioning circulatory systems - that doesn't mean the circulation of their blood is transcendent from their circulatory system.

Let's put it this way..If you believe you're nothing more than material machinery then you don't have free will and you can't even trust your own rationality. You don't have free will because all of your choices are preceeded and caused by unconscious material processes.

This is a complete cop-out. I can say the same to you. If your god is omniscient, then he knows what you are going to do before you do it. Therefore you don't actually have free will because, no matter what, you are going to do what god always expected you to do.

If consciousness is "entirely transcendent of its wiring" then why can damage to that wiring change/destroy the conciousness?

Consciousness is consciousness, whether the brain is damaged or undamaged. The key part is having it, and It stems from the soul. The quality of the consciousness is effected by the relative performance of the medium, but if access to information is lost in the physical, it doesn't mean it is gone. It's purely your assumption that it can be destroyed in any way. The access may be lost in the physical, but it still exists in eternity. God knows everything, so He is the ultimate memory storage for our souls.
As for the French civil servant with Dandy-Walker syndrome, let's get some facts straight: firstly, he has a lower than average IQ and secondly, his brain is not a "small slice in the center of his skull about one inch thick", it is pushed up against the sides of the skull with an empty cavity in the center.
The fact that he isn't lacking in consciousness isn't what makes it newsworthy either. It was newsworthy because he went so long without it being diagnosed and without having the common problems associated with it. The mortality rate for people with this disorder is high, but it isn't uncommon for a survivor with the disorder to have a normal cognition. The reason that is, is because their brain is misshapen and missing pieces, but those missing pieces tend to be the ones that deal with more basic functions like muscle control as opposed to those parts used for consciousness.

"For [many people], freedom of will is synonymous with the idea that, with respect to any specific thought or action, one could have thought or acted differently. But to say that I could have done otherwise is merely to think the thought, “I could have done otherwise” after doing whatever I, in fact, did. Rather than indicate my freedom, this thought is just an epitaph erected to moments past. What I will do next, and why, remains, at bottom, inscrutable to me. To declare my “freedom” is tantamount to saying, “I don’t know why I did it, but it’s the sort of thing I tend to do, and I don’t mind doing it.”
And this is why the last objection is just another way of not facing up to the problem. To say that “my brain” has decided to think or act in a particular way, whether consciously or not, and my freedom consists in this, is to ignore the very reason why people believe in free will in the first place: the feeling of conscious agency. People feel that they are the authors of their thoughts and actions, and this is the only reason why there seems to be a problem of free will worth talking about."
You can't trust your own rationality because it is based upon on chemical reactions in the brain, a process which evolved from the lower animals and with guarantee of any truth. Here's what darwin said about it:
"With me, the horrid doubt always arises whether the convictions of man's mind, which has been developed from the mind of the lower animals, are of any value or at all trustworthy. Would any one trust in the convictions of a monkey's mind, if there are any convictions in such a mind?"
So, if I am speaking to someone who can't make independent choices, with rationality that came from monkeys, why should I believe anything that you're saying?

Here is the hypothesis

http://www.ideacenter.org/contentmgr/showdetails.php/id/1156

Here is a story about ID being published in a biology journal making predictions for cancer research

http://www.discovery.org/a/2627

I am arguing not that there are no differences in the world, but that there is no concrete distinction between life and chemistry. You can assume there is, you can assert there is, but until you can demonstrate that there is I have nothing to disprove.

There is obviously a concrete difference since life doesn't come from non-life, and has never once been observed doing so. You have everything in the world to prove here. Everything in the Universe is made up of atoms, does that mean there is no difference between you and me? Is there no difference between a duck and a neutron star? You can't just say that because there are trivial similarities that they are the same thing.

And if you think like that, and you just believe we are all chemicals in motion, then you can't trust your own mind because if our mental processes are just chemical reactions, then there is no reason to believe anything is true. If our mental states have their origin in non-rational causes, rationality can't be trusted. You can't know if the rationality we have from evolutionary processes is discerning the truth of the world or not. Even Darwin realized this:

The bottom right hydroxyl group is the only difference between RNA and DNA, to suggest that molecules can't lose parts, is to argue that the universe is not as it observably is.

Since the step you clearly label (MAGIC) in the RNA-> DNA path is so obviously trivial, why should anybody believe that the other step you label (MAGIC) is any more complex

?
Well this is plainly false. RNA to DNA is far more probable than ROCKS to RNA. The reason it is labeled magic is because there is no proof. It doesn't mean that they are both equally likely. It is less likely by large orders of magnitude.

The magic is RNA self-replication:

http://www.lifesorigin.com/chap10/RNA-self-replication-3.php

And if you had bothered to do any real research, you would see that the leap from soup to these complex molecules is anything but trivial..here is a list of just of basic issues...

http://www.godandscience.org/evolution/chemlife.html

Some quotes for you:

Instead of revealing a multitude of transitional forms through which the evolution of the cell might have occurred, molecular biology has served only to emphasize the enormity of the gap. We now know not only of the existence of a break between the living and non-living world, but also that it represents the most dramatic and fundamental of all the discontinuities of nature. Between a living cell and the most highly ordered non-biological system, such as a crystal or a snowflake, there is a chasm as vast and absolute as it is possible to conceive....

Molecular biology has also shown that the basic design of the cell system is essentially the same in all living systems on earth from bacteria to mammals. In all organisms the roles of DNA, mRNA and protein are identical. The meaning of the genetic code is also virtually identical in all cells. The size, structure and component design of the protein synthetic machinery is practically the same in all cells.

In terms of the basic biochemical design, therefore no living system can be thought of as being primitive or ancestral with respect to any other system, nor is there the slightest empirical hint of an evolutionary sequence among all the incredibly diverse cells on earth. For those who hoped that molecular biology might bridge the gulf between chemistry and biochemistry, the revelation was profoundly disappointing."

Dr. Denton, Ph.D (Molecular Biology),
An evolutionist currently doing biological research in Sydney, Australia

Now we know that the cell itself is far more complex than we had imagined. It includes thousands of functioning enzymes, each one of them a complex machine in itself. Furthermore, each enzyme comes into being in response to a gene, a strand of DNA. The information content of the gene (it's complexity) must be as great as that of the enzyme it controls.

A medium protein might include about 300 amino acids. The DNA gene controlling this would have about 1,000 nucleotides in its chain, one consisting of a 1,000 links could exist in 41000 different forms. Using a little algebra (logarithms) we can see that 41000 = 10600. Ten multiplied by itself 600 times gives us the figure '1' followed by 600 zeros! This number is completely beyond our comprehension."

Frank Salisbury,
Evolutionary biologist

Perhaps an "effort", but not a method, or a hypothesis. ID makes no predictions, it simply tries to find arguments to prop up a baseless assumption, that is the opposite of science.

If any ID proponent, or any theologian for that matter, can demonstrate even one example of anything true that their ideology can reliably tell us that we don't already know I will admit that it has predictive power, and that it could qualify as a hypothesis, and then eventually a theory. I'm betting you can't find one.

There is no ID hypothesis, Behe came the closest to actually trying, and any competent high school biology student could pick his little charade to pieces in a few hours with a half decent encyclopedia.
Given two possibilities, one being unlikely, and the other being false, I'll go with unlikely.

So you acknowledge that information is trivially synthesized, by
non-minds? That's the opposite of your original claim. Is that a
retraction?

No, see above.

You said, and I quote: "if you already have DNA, you can certainly expect a cell to form."
Do you mean that DNA must already have the information required to do so? because lots of DNA does not, otherwise are you asserting that DNA is somehow "mind", which you claim would be required for that information to come into being?

The distinction between "life" and "non-life" does not exist.
So there is no difference between you and a rock? I can admit I see similarities, heart wise..:)
Let's see some evidence for your claim that there is no difference between life and non-life.

I am arguing not that there are no differences in the world, but that there is no concrete distinction between life and chemistry. You can assume there is, you can assert there is, but until you can demonstrate that there is I have nothing to disprove.
You can't disprove unicorns, I can't disprove the life boundary, and we have no reason to believe either exists.

It's not false. This is your pathway to DNA: RNA - (MAGIC) - DNA This is your pathway to RNA: ROCKS - (MAGIC) - RNA Just because you can get RNA to self-replicate doesn't automatically mean it is either likely or plausible this could happen.

Please consider this image: http://en.citizendium.org/images/thumb/f/f6/RNA_base_vs_DNA_base.jpg/350px-RNA_base_vs_DNA_base.jpg
The bottom right hydroxyl group is the only difference between RNA and DNA, to suggest that molecules can't lose parts, is to argue that the universe is not as it observably is.
Since the step you clearly label (MAGIC) in the RNA-> DNA path is so obviously trivial, why should anybody believe that the other step you label (MAGIC) is any more complex?

It is an effort to empirically detect whether the "apparent" design in nature, which biologists acknowledge, is actual design. It is only useless to you because you have ruled out design apriori, which is just simply ignorant.

Perhaps an "effort", but not a method, or a hypothesis. ID makes no predictions, it simply tries to find arguments to prop up a baseless assumption, that is the opposite of science.
If any ID proponent, or any theologian for that matter, can demonstrate even one example of anything true that their ideology can reliably tell us that we don't already know I will admit that it has predictive power, and that it could qualify as a hypothesis, and then eventually a theory. I'm betting you can't find one.

Perhaps I can be more clear. Christ existing is obviously a necessary condition for Christianity to be true - but it's not sufficient. I suppose some people might say "Oh, Christ never existed so Christianity isn't true", but I don't think anyone's doing that here - and that's why I thought it was an odd thing to bring up. I think most non-Christian people here would say something more like "Jesus probably existed, and probably said more or less the same stuff that's in the Bible - but he didn't do miracles, isn't the Son of God, and didn't come back from the dead".

The belief that Jesus is a myth seems to be more prevelent, actually, and many of the people I have debated here have claimed this. I think only a very unthoughtful and intellectually incurious person could actually believe it, as you'd be hard pressed to even find a secular historian who does. He is by far the most influential person in history, which continues to this day. That in itself speaks to His claims. Our great land was founded on judeo-christian values, and the freedom that we enjoy today was predcated upon those values of personal liberty.. Even the pursuit of science was founded upon Christian understaniding; It was thought we could determine the operation of the cosmos because the Universe is orderly and has regularity due to Gods oversight. Yet, even with all this some people close their eyes to the simple truth that Jesus Christ even existed. Yet, these are the same people who champion their own rationality as being superior.

This martyr argument is another one you come back to, but surely with any reflection you understand why it isn't convincing. Christianity doesn't have a monopoly on martyrs - there's been plenty of, for example, Muslims who've chosen to die for their beliefs in a great variety of circumstances, sometimes very pro-active ones. But even if Christianity has the most (or most spectacular martyrs), certainly there are many people who've died for all sorts of causes: religious, secular, or personal.

While it certainly says Christianity is a powerful idea that so many have died for it, I don't think an idea has to be true to prompt this level of conviction.


I think the martyr argument is very powerful when you consider the original disciples. They were the ones who truly knew if Jesus was in fact risen. If Jesus was not raised from the dead, there isn't any plausible explanation as to why they would all willingly die for something they knew to be a lie, when all they had to do was recant their testimony. It is also powerful for the early church because it was formed in the times of the living witnesses of Christ, and it was under very heavy persecuation. It was to a persons great disadvantage to follow Christ, socially, economically, and was often putting your life on the line. Being a Christian then was like being a Christian in Iran today. There is no good reason why the church should have ever survived under those conditions, but it did more than; it thrived and expanded expodentially. Yes, people martyr themselves today..most notably members of Islam. Islam isn't under persecution though..people are indoctrinated from birth and told if they even think one bad thought about Allah they will face eternal torment. There is no atonement in Islam, so if you screw up once you're done for. Under these conditions, and considering that Islam advocates exterminating all other religions and people, it isn't surprising it creates conditions in which people willingly martyr themselves. These situations however are night and day in regards to motivation.

First off, I should say that I appreciate the effort you're putting into legitimate debate here. I do. While I disagree with your recent points, I also accept them as honest reasoning and I think we're discussing things on a better level than we have in the past. So thanks, and I'll try to rein in my own douchebag forum persona.

Anyways, I'll (hopefully) explain what I was trying to get at better. It is my belief that religions often effectively "poison the well" for detractors by saying that the detractors are doing so for alternative motives, or that those detractors cannot understand the truth because of some flaw. To illustrate this, I was saying that Scientologists are quick to call out detractors (who are, to be fair, usually former members with a grievance) for their character flaws or crimes. Facetiously (because I don't actually know Scientologist beliefs), I was suggesting that they might also blame detractors' disagreements on confusing Thetans.

I was attempting to illustrate how awkward this attack is to refute for the detractor. The detractor certainly does have "crimes" (because, as I think we all agree, people all do things they aren't proud of). And he certainly can't be convincing if he says he has no Thetans. How can he make the case for that, when he doesn't even believe in Thetans anymore, and is definitely no longer being cleared of them?
From a perspective of a non-believer, a Christian detractor is in a similar position. Many (or even most) will have personal grievances that make their arguments sound suspect. And all will have sins. Many will have sins associated with their departure. Given that it's common Christian thought that sin clouds thought (or bars revelation or conscience or similar), we're left with a tidy way to undermine almost all detractors.


The most common objection I hear from someone is not that they haven't done evil, or that they aren't guilty of crimes against God. It's not even that they would disagree that they deserve to be punished. It's that they just defacto reject Gods authority over them because they don't want to stop living the way they do. In a very real way, they reject God over their preference to sin as they wish. This is exactly what the bible means in John 3:19-21 when it says:

This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil

Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed.

But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God.


Even Christopher Hitchens outright admits it. Skip to 6:26 for his confession.

A person who is railing against Christianity due to personal grievances is not only not rational, but is completely disingenuous. Such a person willfully avoids the truth, because their objection isn't based on rational grounds, but emotional ones. I have yet to meet a single person who has a legitimate gripe against Christianity as it is described in the bible. It is all due to the failings of men who didn't live up to Gods word. Yet, to the world you're a Christian if you say you are, and every evil thing man has done in the name of Christianity is ascribed to it, ignoring the fact Christ specifically taught against it.

I understand your argument..but you're basically saying it's unfair because the bible accurately describes the condition of man. That it's easy for a Christian to pigeonhole unbelievers because man is in fact habitually evil and hypocritical as the bible describes.. Man has a sin problem, but how is it any different when one might reference a scientific worldview. To blame the wickedness of human beings on animal instincts, or the "reptile brain" (serpent consciousness), or chemical reactions. Survival of the fittest. Science even says that people who believe in God have it in their DNA to do so, and even associate it to a certain area of the brain. There is no real empirical evidence for any of this, so how is it much different than saying man is corrupted by sin? It really isn't. They are competing worldviews. Science says it's a physical issue, but the bible says it is spiritual. Only one can be right.

So my overall point is an analogy. Both the Scientologist and the Christian believer have similar reasons to doubt the detractor. However, I think we'd both agree that the Scientologist detractor is right despite those reasons. So while I understand that you still would not accept the Christian detractor, my point would be that we can't completely refute him on these grounds because he could (in principle) be the same as the Scientologist detractor. The differences between the Christian and the Scientologist detractor (with regards to these ideas) are generally only differences from the perspective of someone who already believes Christianity and not Scientology (and certainly I think we'd agree that believing Christianity is more rational than believing Scientology - I'm just using it as a convenient analogy).

My point was that instead of looking at him (the detractor) in terms of his grievances, or in terms of factors (like sin or Thetans) that could cloud his judgement - it's safer to just consider his arguments, which will stand or fall on their own qualities regardless of the speaker.


Yes, I do understand your analogy. Yes, a scientologist might reject a detractor because they think he has thetans, but we know those are made up. There is a similarity in that basic approach, but since Scientology is easily disproven, there aren't any arguments to consider. In that case, people are rejecting his truth because its clearly not true, not because it isn't possible that people reject truth because they are corrupted by evil. It's still a strawman any way you look at it. The point here is, what is the best explanation for reality and the human condition. If it is true that everyone sins, and that people are hypocrites, then that is something you as an unbeliever have to come to terms with. If I can accurately portray the human condition better than you can, and give reasonable explanations for human behavior according to biblical truth, those are obviously points in favor of the bible and not some cheap tact. It's perfectly legimate to point out that the objective stance people claim to take (and the claim they lay to reason itself) is mostly just smoke and mirrors for their personal prejudices and very real rebellion against Gods authority.

Tommy Chong Confronts "War on Drugs" Profiteer

>> ^tsquire1:

What a fucking tool. Marijuana addiction? addiction?
Y'all know that SB1070 was written by Corrections Corporation of America, right? Y'all know why? Because undocumented people are seen as a source of profit ($200 per bed, per night). Same thing goes for the 'war on drugs'. Its a way for the capitalist scum to profit off our misery.
Fuck 'em


So the brain can't become addicted to the chemical reactions it receives from THC? Is that what you're saying? Why is it so far-fetched to you that marijuana is very much an addictive substance? It may not be as addictive as some other things such as methamphetamines but it most certainly is addictive. ANYTHING can be addictive if the brain sees a reward from it. Gaming, extreme sports, drugs, alcohol, even reading can be addictive. Weed IS addictive and denying that fact is only keeping yourself in the dark.

Of COURSE people make money off of it. What don't people try to capitalize on? That doesn't make it any less true that it's an affliction for many people.
