Safe nuclear refers to many different new gen4 reactor units that rely on passive safety instead of engineered safety. The real difference comes with a slight bit of understanding of how nuclear tech works now, and why that isn't optimal.
Let us first consider this, even with current nuclear technology, the amount of people that have died as a direct and indirect result of nuclear is very low per unit energy produced. The only rival is big hydro, even wind and solar have a great deal of risk compared to nuclear as we do it and have done it for years. The main difference is when a nuclear plant fails, everyone hears about it...but when a oil pipeline explodes and kills dozens, or solar panel installers fall off a roof or get electrocuted and dies...it just isn't as interesting.
Pound per pound nuclear is already statistically very safe, but that isn't really what we are talking about, we are talking about what makes them more unsafe compared to new nuclear techs. Well, that has to do with how normal nukes work. So, firstly, normal reactor tech uses solid fuel rods. It isn't a "metal" either, it is uranium dioxide, has the same physical characteristics as ceramic pots you buy in a store. When the fuel fissions, the uranium is transmuted into other, lighter, elements some of which are gases. Over time, these non-fissile elements damage the fuel rod to the point where it can no longer sustain fission and need to be replaced. At this point, they have only burned about 4% of the uranium content, but they are all "used up". So while there are some highly radioactive fission products contained in the fuel rods, the vast majority is just normal uranium, and that isn't very radioactive (you could eat it and not really suffer any radiation effects, now chemical toxicity is a different matter). The vast majority of nuclear waste, as a result of this way of burning uranium, generates huge volumes of waste products that aren't really waste products, just normal uranium.
But this isn't what makes light water reactors unsafe compared to other designs. It is all about the water. Normal reactors use water to both cool the core, extract the heat, and moderate the neutrons to sustain the fission reaction. Water boils at 100c which is far to low a temperature to run a thermal reactor on, you need much higher temps to get power. As a result, nuclear reactors use highly pressurized water to keep it liquid. The pressure is an amazingly high 2200psi or so! This is where the real problem comes in. If pressure is lost catastrophically, the chance to release radioactivity into the environment increases. This is further complicated by the lack of water then cooling the core. Without water, the fission chain reaction that generates the main source of heat in the reactor shuts down, however, the radioactive fission products contained in the fuel rods are very unstable and generate lots of heat. So much heat over time, they end up causing the rods to melt if they aren't supplied with water. This is the "melt down" you always hear about. If you start then spraying water on them after they melt down, it caries away some of those highly radioactive fission products with the steam. This is what happened in Chernobyl, there was also a human element that overdid all their safety equipment, but that just goes to show you the worst case.
The same thing didn't happen in Fukushima. What happened in Fukushima is that coolant was lost to the core and they started to melt down. The tubes which contain the uranium are made from zirconium. At high temps, water and zirconium react to form hydrogen gas. Now modern reactor buildings are designed to trap gases, usually steam, in the event of a reactor breach. In the case of hydrogen, that gas builds up till a spark of some kind happens and causes an explosion. These are the explosions that occurred at Fukushima. Both of the major failures and dangers of current reactors deal with the high pressure water; but water isn't needed to make a reactor run, just this type of reactor.
The fact that reactors have radioactive materials in them isn't really unsafe itself. What is unsafe is reactor designs that create a pressure to push that radioactivity into other areas. A electroplating plant, for example, uses concentrated acids along with high voltage electricity in their fabrication processes. It "sounds" dangerous, and it is in a certain sense, but it is a manageable danger that will most likely only have very localized effects in the event of a catastrophic event. This is due mainly to the fact that there are no forces driving those toxic chemical elements into the surrounding areas...they are just acid baths. The same goes for nuclear materials, they aren't more or less dangerus than gasoline (gas go boom!), if handled properly.
I think one of the best reactor designs in terms of both safety and efficiency are the molten salt reactors. They don't use water as a coolant, and as a result operate at normal preasures. The fuel and coolant is a liquid lithium, fluoride, and beryllium salt instead of water, and the initial fuel is thorium instead of uranium. Since it is a liquid instead of a solid, you can do all sorts of neat things with it, most notably, in case of an emergency, you can just dump all the fuel into a storage tank that is passively cooled then pump it back to the reactor once the issue is resolved. It is a safety feature that doesn't require much engineering, you are just using the ever constant force of gravity. This is what is known as passive safety, it isn't something you have to do, it is something that happens automatically. So in many cases, what they designed is a freeze plug that is being cooled. If that fails for any reason, and you desire a shutdown, the freeze plug melts and the entire contents of the reactor are drained into the tanks and fission stops (fission needs a certain geometry to happen).
So while the reactor will still be as dangerous as any other industrial machine would be...like a blast furnace, it wouldn't pose any threat to the surrounding area. This is boosted by the fact that even if you lost containment AND you had a ruptured emergency storage tank, these liquid salts solidify at temps below 400c, so while they are liquid in the reactor, they quickly solidify outside of it. And another great benefit is they are remarkably stable. Air and water don't really leach anything from them, fluoride and lithium are just so happy binding with things, they don't let go!
The fuel burn up is also really great. You burn up 90% of what you put in, and if you try hard, you can burn up to 99%. So, comparing them to "clean coal" doesn't really give new reactor tech its fair shake. The tech we use was actually sort of denounced by the person who made them, Alvin Weinberg, and he advocated the molten salt reactor instead. I could babble on about this for ages, but I think Kirk Sorensen explains that better than I could...hell most likely the bulk of what I said is said better by him
http://www.youtube.com/watch?v=N2vzotsvvkw
But the real question is why. Why use nuclear and not solar, for instance?
http://en.wikipedia.org/wiki/Energy_density
This is the answer. The power of the atom is a MILLION times more dense that fossil fuels...a million! It is a number that is beyond what we can normal grasp as people. Right now, current reactors harness less that 1% of that power because of their reactor design and fuel choice.
And unfortunately, renewables just cost to darn much for how much energy they contribute. In that, they also use WAY more resources to make per unit energy produced. So wind, for example, uses 10x more steal per unit energy contributed than other technologies. It is because renewables is more like energy farming.
http://videosift.com/video/TEDxWarwick-Physics-Constrain-Sustainable-Energy-Options
This is a really great video on that maths behind what makes renewables less than attractive for many countries. But to rap it up, finally, the real benefit is that cheap, clean power is what helps makes nations great. There is an inexorable link with access to energy and financial well being. Poor nations burn coal to try and bridge that gap, but that has a huge health toll. Renewables are way to costly for them per unit energy, they really need other answers. New nuclear could be just that, because it can be made nearly completely safe, very cheap to operate, and easier to manufacture (this means very cheap compared to today's reactors as they are basically huge pressure vessels). If you watch a couple of videos from Kirk and have more questions or problems, let me know, as you can see, I love talking about this stuff Sorry if I gabbed your ear off, but this is the stuff I am going back to school for because I do believe it will change the world. It is the closest thing to free energy we are going to get in the next 20 years.
In reply to this comment by ReverendTed:
Just stumbled onto your profile page and noticed an exchange you had with dag a few months back.
What constitutes "safe nuclear"? Is that a specific type or category of nuclear power?
Without context (which I'm sure I could obtain elsewise with a simple Google search, but I'd rather just ask), it sounds like "clean coal".

World Chess #1 Explains How His Mind Works
>> ^Sotto_Voce:
Fischer was ridiculously dominant in his heyday, but comparing players across eras is difficult. Chess has become so much more professionalized now. The players train a lot harder, and more importantly they have computers to help them train, so in general players at the top levels now have a much tighter game than their counterparts in the 70s. It's kind of like tennis: if you judge based on dominance over his peers, Rod Laver is the greatest tennis player of all time, but I'm sure Federer, Nadal or Djokovic could absolutely spank Laver in his prime.
Still, you'll get no argument from me if you believe Fischer is a strong contender for the "greatest ever" title. I still prefer Kasparov, but I might be biased because Kasparov isn't a racist lunatic. It's good to know that it's possible for a person to be a transcendent chess genius and still be a functional human being.
Fischer is a stupid racist idiot. However Kasparov is a politician...soo not much better in my book.
World Chess #1 Explains How His Mind Works

#1 ranked in the world...I'll be Kasparov could come outa retirement and destroy this kid. Young whipper snappers. Also the FIDE rating is sort of messed up in certain ways. This guy though can play 10 games at once not looking at the board, that's a special sort of autism right there, pretty neat.
He has played Kasparov before, as he mentions at the end of the clip. They played two matches in 2004. One was a draw and Kasparov won the other one. Of course, Carlsen was only 13 back then, so I think he'd have a considerably better shot now. Anyway, very few chess players can hold a candle to Kasparov in his prime, but Carlsen is one of them, even though their playing styles are very different. Whether his career will be as impressive as Kasparov's remains to be seen, but he's definitely had a good start: youngest world number 1 ever, second highest FIDE ranking ever. He needs to win the World Championship now, but I'm sure that's coming. Incidentally, Kasparov actually coached Carlsen for a little while.
Fuck off with all this helpful information! Anyways Kasparov has been retired for a long time, so yeah Carlsen would probably take him. I still think FIDE rankings are bullshit, the best chess master ever as Fischer dammit!

Epic Stop Motion (Gundam) Battle
It seems to be one of the older original gundam series before they became super powered up.
A few things irk me on this animation though.
1) manual cocking of the guns.. not one but several of the weapons used here seem to have manual rod latches... WHY?! Gundam weapons should have zero problems having their internal bullet feeding mechanism be totally automatic. It isn't super mario 3 where the world of humans was made smaller, the guns are bigger, much bigger.
2) No radio communication? in the anime series they never seemed to be able to shut up.
3) Wide spread shots during air combat made bullet dodging convincing in the anime, but not so much on the ground. Gundams were usually forced to absorb a shot or two before quickly dispatching mobile armors, not play neo and dodge everything with matrix like reflexes.
Why Christians Can Not Honestly Believe in Evolution
"Ok, you need to understand two different concepts........the odds of getting so much similarity by accident is exceedingly small.
So in light of this reality.....supposedly bring down evolution."
Minor disagreements? I'm having a hard time believing that you've seriously investigated this subject if you are now claiming (scaled back from your prior claim of perfect agreement between "scores" of them) that molecular and morphological phylogonies typically have a high level of agreement. They don't. Agreement is the exception, not the rule. Even worse, molecular phylogonies don't agree with eachother either:
As morphologists with high hopes of molecular systematics, we end this survey with our hopes dampened. Congruence between molecular phylogenies is as elusive as it is in morphology and as it is between molecules and morphology. . . .
Partly because of morphology’s long history, congruence between morphological phylogenies is the exception rather than the rule. With molecular phylogenies, all generated within the last couple of decades, the situation is little better. Many cases of incongruence between molecular phylogenies are documented above; and when a consensus of all trees within 1% of the shortest in a parsimony analysis is published (e.g. 132, 152, 170), structure or resolution tends to evaporate
Congruence Between Molecular and Morphological Phylogenies
http://www.annualreviews.org/doi/abs/10.1146/annurev.es.24.110193.001101
"If only you were a bit better at it. Even the quotes you chose to mine serve to undermine your point. I think my point can be summarized by the following quote from your reference"
“On one side stand traditionalists who have built evolutionary trees from decades of work on species' morphological characteristics. On the other lie molecular systematists, who are convinced that comparisons of DNA and other biological molecules are the BEST way to unravel the secrets of evolutionary history.”
The relevant part here is the word “best.” These people are clearly just trying to decide what the most accurate method of phylogenetic determination is and this article represents nothing more than a discussion of one of the many battles that go on in the constant refinement of science. And this disagreement does nothing at all to disprove evolution""
Your charge of quote mining is false. Quote mining is the logical fallacy of quoting something out of context, distorting its intended meaning. The quote I provided was very much in context, and showed support for the assertion that molecular and morphological phylogenies do not have "perfect" agreement, and now I have further supported that assertion (and disproven your scaled back claim of very statistically significant agreement) that their agreement is actually very superficial. It is far more significant how little agreement there actually is.
The very reason there is a contention about which is the "best" method is precisely because there is so little agreement. In any case, molecular homology appears to be winning the battle, perhaps because the evolutionists are getting tired of never finding any evolution in the fossil record.
Which brings us to the many issues with molecular homologies, specifically, their lack of falsifiability:
"We believe that it is possible to draw up a list of basic rules that underlie existing molecular evolutionary models:
All theories are monophyletic, meaning that they all start with the Urgene and the Urzelle which have given rise to all proteins and all species, respectively.
Complexity evolves mainly through duplications and mutations in structural and control genes.
Genes can mutate or remain stable, migrate laterally from species to species, spread through a population by mechanisms whose operation is not fully understood, evolve coordinately, splice, stay silent, and exist as pseudogenes.
Ad hoc arguments can be invented (such as insect vectors or viruses) that can transport a gene into places where no monophyletic logic could otherwise explain its presence.
This liberal spread of rules, each of which can be observed in use by scientists, does not just sound facetious but also, in our opinion, robs monophyletic evolution of its vulnerability to disproof, and thereby its entitlement to the status of a scientific theory.
The absolute, explicit and implicit, adherence to all the monophyletic principle and consequently the decision to interpret all observations in the light of this principle is the major cause of incongruities as well as for the invention of all the genetic sidestepping rules cited above."
A Polyphyletic View of Evolution
Schwabe and Warr
This is why Schwabe, a biochemist, wrote:
Molecular evolution is about to be accepted as a method superior to paleontology for the discovery of evolutionary relationships. As a molecular evolutionist I should be elated. Instead it seems disconcerting that many exceptions exist to the orderly progression of species as determined by molecular homologies; so many, in fact, that I think the exception, the quirks, may carry the more important message
It's a shell game where virtually any kind of data can be accomodated, and at no point is the theory questioned. Ad hoc explanations can be invented for any kind of discrepency.
""There are analogous debates going on in nearly all branches of academic study. Taking an example with fewer existential implications for religion, look towards the Holocaust. There is an ongoing effort by Yad Va Shem, a jewish organization, to catalogue all those who died under the Nazi regime as well as those who aided jews in various ways (http://www1.yadvashem.org/yv/en/remembrance/hall_of_names.asp). Now at the moment they have verified only three million names and something like 24000 people who helped, and details on each vary. But wait, oh no! We all know that there were roughly six million victims! And we don’t even have complete information about the paltry three million we’ve catalogued. Does this mean that the Holocaust did not happen? Of course it doesn’t. You need to take the internal debate in context and realize that the total sum of evidence is overwhelming. Creationists, however, can not be so objective with such a threatening theory as evolution.""
A mountain of weak, circumstantial evidence (much of which contradicts itself) does not prove macro evolution. "We're working on it" does not somehow validate that evidence. We know the holocaust happened; there is no proof for macro evolution.
""As for your junk DNA article, you similarly blow the relevance way out of proportion. Here’s the last sentence from the text that summarizes the relevance of the article:
“The present study suggests that some selfish DNA transposons can instead confer an important role to their hosts, thereby establishing themselves as long-term residents of the genome.”
Here it states simply that some of the junk DNA, not all of it, can become useful to the cell. This sentence proves you wrong in two ways. First, it admits that they have only found a few instances of utility for this junk DNA, which is a far cry from the evidence that would be necessary for the slow death you speak of. Second, the acknowledges that this as an instance of Junk DNA incorporating itself into the genome and taking on novel and useful roles. In other words, evolution!
The genome is huge and nowhere in biology does it say that all of the DNA we have designated as junk is most certainly junk. Again, this is just another example of incrementally refining our understanding about how things work, but it is not revolutionary and it still demonstrates a clear framework.
And regardless or whether or not your article shows that a lot of Junk DNA has function (which is common knowledge, by the way), it does not at all disprove the fact that junk DNA shows typically exhibits much higher rates of mutation because its specific sequence is less rigidly constrained than coding DNA (http://www.nature.com/nrg/journal/v12/n11/full/nrg3098.html?WT.ec_id=NRG-201111). It is not a complete lack of function that demonstrates evolution, but simply a higher rate of mutation that results in sequences that will be more varied the more distantly related two species are.""
There are numerous sources showing that junk dna is not junk:

http://www.nature.com/scitable/topicpage/transposons-or-jumping-genes-not-junk-dna-1211
Based on your earlier argument, "we're working on it", you should realize that what some scientists consider to be junk dna stems entirely from ignorance. The idea that it got in there by "viral dna insertions" and the like is simply another ad hoc explanation among many.

@shinyblurry - No, yours is and here's why:
Ok, you need to understand two different concepts. The first, is the notion that science is constantly refining itself. It is never 100% correct, and there is near constant debate about what is the best method of determining something to be factual. In this case, we're talking about whether molecular systematics or morphological characteristics are the most accurate means of determining phylogeny. The second is the notion of statistical significance. Now I'll admit that in saying that they "coincide perfectly," I failed to adhere to a more accurate and rigorous description of what is actually happening, so I'll rectify that now. The correlation between the different trees constructed by different fields within biology have an extremely statistically significant amount of correlation. This means that while we can expect disagreement and there will be debate about the best method to refine the results, the odds of getting so much similarity by accident is exceedingly small.
So in light of this reality where science is never 100% correct and there is a constant debate over the relative effectiveness of varying methods of phylogenetic determination, there will be a huge excess of material for you to quote mine in an effort to distort the significance of the minor disagreements that are common in science to a scale that can supposedly bring down evolution.

There is an ongoing effort by Yad Va Shem, a jewish organization, to catalogue all those who died under the Nazi regime as well as those who aided jews in various ways (http://www1.yadvashem.org/yv/en/remembrance/hall_of_names.asp). Now at the moment they have verified only three million names and something like 24000 people who helped, and details on each vary. But wait, oh no! We all know that there were roughly six million victims! And we don’t even have complete information about the paltry three million we’ve catalogued. Does this mean that the Holocaust did not happen? Of course it doesn’t. You need to take the internal debate in context and realize that the total sum of evidence is overwhelming. Creationists, however, can not be so objective with such a threatening theory as evolution.
As for your junk DNA article, you similarly blow the relevance way out of proportion. Here’s the last sentence from the text that summarizes the relevance of the article:
“The present study suggests that some selfish DNA transposons can instead confer an important role to their hosts, thereby establishing themselves as long-term residents of the genome.”
Here it states simply that some of the junk DNA, not all of it, can become useful to the cell. This sentence proves you wrong in two ways. First, it admits that they have only found a few instances of utility for this junk DNA, which is a far cry from the evidence that would be necessary for the slow death you speak of. Second, the acknowledges that this as an instance of Junk DNA incorporating itself into the genome and taking on novel and useful roles. In other words, evolution!
The genome is huge and nowhere in biology does it say that all of the DNA we have designated as junk is most certainly junk. Again, this is just another example of incrementally refining our understanding about how things work, but it is not revolutionary and it still demonstrates a clear framework.
And regardless or whether or not your article shows that a lot of Junk DNA has function (which is common knowledge, by the way), it does not at all disprove the fact that junk DNA shows typically exhibits much higher rates of mutation because its specific sequence is less rigidly constrained than coding DNA (http://www.nature.com/nrg/journal/v12/n11/full/nrg3098.html?WT.ec_id=NRG-201111). It is not a complete lack of function that demonstrates evolution, but simply a higher rate of mutation that results in sequences that will be more varied the more distantly related two species are.
And finally, read these articles if you want a more complete understanding about how the comparisons between phylogenetic trees are indeed imperfect, but well supported and constantly refined:

Santorum: I Don't Believe in Separation of Church and State
Well, despite your condescending tone, you at least have a quote and make a valid point. Nice work.
I'll try to wrap my tiny brain around these life-shattering ideas. I'm not sure how well I'll do after how soundly you made fun of my education, or lack thereof. I thought I had a pretty good public school education. Thank you for showing me the light, that I was obviously the victim of liberal elites who spent too much time getting us to read and think rather than indoctrinating us. We didn't focus too much on what religion early Americans subscribed to, we just learned what they did. They called this "history." Maybe I'll come to an epiphany and find that I too want to write a revisionist history showing how all the founding fathers were really ancient pre-neo-cons, who went on religious crusades to oust any shred of diversion from the One True Faith from this, God's greatest country of all time. Amen.
I'm sorry, I did not mean to be condescending. What they call American history today sanitizes the role of Christianity, to the point that the youth is completely unaware of this nations deeply rooted Christian heritage. The seculization of this country is a recent phenomena. Look at these state constitutions:
Constitution of the State of North Carolina (1776), stated:
There shall be no establishment of any one religious church or denomination in this State in preference to any other.
Article XXXII That no person who shall deny the being of God, or the truth of the Protestant religion, or the divine authority of the Old or New Testaments, or who shall hold religious principles incompatible with the freedom and safety of the State, shall be capable of holding any office or place of trust or profit in the civil department within this State. (until 1876)
In 1835 the word “Protestant” was changed to “Christian.” [p.482]
Constitution of the State of Maryland (August 14, 1776), stated:
Article XXXV That no other test or qualification ought to be required, on admission to any office of trust or profit, than such oath of support and fidelity to this State and such oath of office, as shall be directed by this Convention, or the Legislature of this State, and a declaration of a belief in the Christian religion.”
That, as it is the duty of every man to worship God is such a manner as he thinks most acceptable to him; all persons professing the Christian religion, are equally entitled to protection in their religious liberty; wherefore no person ought by any law to be molested… on account of his religious practice; unless, under the color [pretense] of religion, any man shall disturb the good order, peace or safety of the State, or shall infringe the laws of morality… yet the Legislature may, in their discretion, lay a general and equal tax, for the support of the Christian religion. (until 1851) [pp.420-421]
Constitution of the State of South Carolina (1778), stated:
Article XXXVIII. That all persons and religious societies who acknowledge that there is one God, and a future state of rewards and punishments, and that God is publicly to be worshipped, shall be freely tolerated… That all denominations of Christian[s]… in this State, demeaning themselves peaceably and faithfully, shall enjoy equal religious and civil privileges. [p.568]
The Constitution of the State of Massachusetts (1780) stated:
The Governor shall be chosen annually; and no person shall be eligible to this office, unless, at the time of his election… he shall declare himself to be of the Christian religion.
Chapter VI, Article I [All persons elected to State office or to the Legislature must] make and
subscribe the following declaration, viz. “I, _______, do declare, that I believe the Christian religion, and have firm persuasion of its truth.”
Part I, Article III And every denomination of Christians, demeaning themselves peaceably, and as good subjects of the commonwealth, shall be equally under the protection of the law: and no subordination of any sect or denomination to another shall ever be established by law.” [p.429]
But, until I get to that, might as well spout my hippie babble…
First, I'm not going to do your little workbook assignment. I grant, and did grant in my previous posts, that many of the founders could be considered "Christians." I'll also grant that Washington, Jefferson and Adams all went to church regularly and, at the birth of our country, "going to church" was a common social activity.
In this way, religion was woven into the fabric of American society. This is why, in my previous posts, I never said that all the founders were deists or non-believers, but that they understood deism and let it inform their understanding of their own, personal religion. More importantly, they let deism inform how they set up American government.
It wasn't just a social phenomena. Christianity has shaped our nation at the roots. Consider the Mayflower Compact, the first governing document of the Plymoth Colony:
"In the name of God, Amen. We whose names are under-written, the loyal subjects of our dread sovereign Lord, King James, by the grace of God, of Great Britain, France, and Ireland King, Defender of the Faith, etc.
Having undertaken, for the glory of God, and advancement of the Christian faith, and honor of our King and Country, a voyage to plant the first colony in the northern parts of Virginia, do by these presents solemnly and mutually, in the presence of God, and one of another, covenant and combine our selves together into a civil body politic, for our better ordering and preservation and furtherance of the ends aforesaid; and by virtue hereof to enact, constitute, and frame such just and equal laws, ordinances, acts, constitutions and offices, from time to time, as shall be thought most meet and convenient for the general good of the Colony, unto which we promise all due submission and obedience. In witness whereof we have hereunder subscribed our names at Cape Cod, the eleventh of November [New Style, November 21], in the year of the reign of our sovereign lord, King James, of England, France, and Ireland, the eighteenth, and of Scotland the fifty-fourth. Anno Dom. 1620."
Consider that the "Old Deluder Satan Act", enacted so that Americans would learn scripture and not be deceived by Satan, is the first enactment of public education in this country.
When you say the say our government was influenced by Deism, and not Christianity, you have a long way to go to prove that. At least 50 of the framers were Christians, out of 55.
http://www.adherents.com/gov/Founding_Fathers_Religion.html
Every single president has taken his oath on the bible and referred to God in his inaugural address.
The supreme court, after an exaustive 10 year study, declared in 1892 in the Holy Trinity decison "This is a relgious people. This is a Christian nation.".
The supreme court opens every session with "God save the United States of America.
The reasoning behind the checks and balances is because man has a fallen nature and cannot be trusted with absolute power:
"It may be a reflection on human nature, that such devices should be necessary to control the abuses of government. But what is government itself, but the greatest of all reflections on human nature? If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself."
James Madison
It would be incredulous if I had suggested that these men outright rejected Christianity. They did not, nor is it the purpose of the establishment clause to reject any religious sect (the establishment clause, and Santorum's misinterpretation of it, you'll remember, is the main subject of this comment thread).
As I said, you cite some valid evidence that the concept of god has always been a part of our government. But, you also haphazardly claim long-dead men to be zealous Christians when there are plenty of primary source documents to suggest they were not. I'm saving my big quote for something that has to do with the establishment clause directly, so you'll have to do your own homework if you want to find the many instances where all of the men you reference criticize organized religion. They are there, and if you like, we can have a quote war in later posts.
Here's my long quote response to you, more on topic than yours, I think:
"Gentlemen,
The affectionate sentiments of esteem and approbation which you are so good as to express towards me, on behalf of the Danbury Baptist Association, give me the highest satisfaction. My duties dictate a faithful and zealous pursuit of the interests of my constituents, and in proportion as they are persuaded of my fidelity to those duties, the discharge of them becomes more and more pleasing.
Believing with you that religion is a matter which lies solely between man and his God, that he owes account to none other for his faith or his worship, that the legislative powers of government reach actions only, and not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should "make no law respecting an establishment of religion, or prohibiting the free exercise thereof," thus building a wall of separation between church and State. Adhering to this expression of the supreme will of the nation in behalf of the rights of conscience, I shall see with sincere satisfaction the progress of those sentiments which tend to restore to man all his natural rights, convinced he has no natural right in opposition to his social duties.
I reciprocate your kind prayers for the protection and blessing of the common Father and Creator of man, and tender you for yourselves and your religious association, assurances of my high respect and esteem."
-TJ 1802
Do you not realize that this very letter you are citing, which TJ wrote to the Danbury Baptist association from France, is the entire foundation of the claim of "seperation of church and state"? Those words do not appear in the constitution or anywhere else. It was only a series of court rulings starting in 1947 which interpreted the establishment clause through this particular letter that led to "seperation of church and state" as we know it today. However, this interpretation, in light of the evidence I presented you in the previously reply, is obviously false. The "wall of seperation" that Jefferson is referring to does not mean what you and the liberal courts think it means. If it did, again..why would Jefferson attend church in the house of representitives? Why would he gives federal funds to Christian missionaries? Why would he be okay with teaching the bible in public schools? None of that makes any sense in light of the interpretation that is espoused today. Consider these quotes from William Rehnquist, former chief justice of the supreme court:
"But the greatest injury of the 'wall' notion is its mischievous diversion of judges from the actual intentions of the drafters of the Bill of Rights. . . . The "wall of separation between church and state" is a metaphor based on bad history, a metaphor which has proved useless as a guide to judging. It should be frankly and explicitly abandoned.”
“It is impossible to build sound constitutional doctrine upon a mistaken understanding of constitutional history. . . . The establishment clause has been expressly freighted with Jefferson's misleading metaphor for nearly forty years. . . . There is simply no historical foundation for the proposition that the framers intended to build a wall of separation [between church and state]. . . . The recent court decisions are in no way based on either the language or the intent of the framers.”
I think this gets to the heart of the matter better than you or I ever could. For you, it shows that Jefferson wasn't shy about using religious rhetoric and proclaiming that he believed enough in Christianity to appeal to this group of clergymen on their home turf.
For me, it shows exactly (though more aptly worded than I could pull off) the point I and others have been making in this comment thread. Not that the founders were without religion, but that they realized the danger of letting religious "opinions" guide legislative policy. It speaks volumes of their intellect that these men, even when living in a society where being religiously aligned was the norm, even having attended seminary and church on a regular basis, still sought fit to vote against aligning their new country to any one religious sect.
There are plenty of founders who believed that Christianity was central to our identity as a nation. Why do you think it says in the declaration of independence:
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
It says our rights come from God and not from men. Why do the founders say things like this:
"Resistance to tyranny becomes the Christian and social duty of each individual. ... Continue steadfast and, with a proper sense of your dependence on God, nobly defend those rights which heaven gave, and no man ought to take from us."
John Hancock
"And as it is our duty to extend our wishes to the happiness of the great family of man, I conceive that we cannot better express ourselves than by humbly supplicating the Supreme Ruler of the world that the rod of tyrants may be broken to pieces, and the oppressed made free again; that wars may cease in all the earth, and that the confusions that are and have been among nations may be overruled by promoting and speedily bringing on that holy and happy period when the kingdom of our Lord and Saviour Jesus Christ may be everywhere established, and all people everywhere willingly bow to the sceptre of Him who is Prince of Peace."
--As Governor of Massachusetts, Proclamation of a Day of Fast, March 20, 1797.
Samuel Adams
Cursed be all that learning that is contrary to the cross of Christ."
James Madison
“To the distinguished character of Patriot, it should be our highest glory to add the more distinguished character of Christian."
George Washington
God who gave us life gave us liberty. And can the liberties of a nation be thought secure when we have removed their only firm basis, a conviction in the minds of the people that these liberties are of the Gift of God?”
Thomas Jefferson
This is why some of us get bent out of shape when Santorum proves his ignorance on this issue. He may understand the establishment clause, but if so, he presents his position as an appeal to ultra-religious citizens. When he addresses arguments against his stance, he interprets them as "a religious person cannot participate in government."
I'll say it again: Religious citizens have just as much right to participate in government as anyone else. But, their opinions, if they are to be considered in an official capacity, must stand on their own merit. Laws are not just if their only basis is: Jesus says so.
I think the misunderstanding is entirely on your side of the debate. Atheists are basically trying to rewrite history and say this nation was intended to be secular, when all evidence points the other direction.
i sincerely esteem the constitution a system which, without the finger of god, never could have been agreed upon by such a diversity of interests
Alexander Hamilton
Atheists are trying to remove God from every sphere of public life, even suing to remove the word God from logos or remove nativity scenes from public property. That was never the intention of the founders. Many of them were openly religious and felt free to use the government and government funding towards furthering Christianity.
It would be akin to you inviting me to stay at your house, and then I inform you that I am going to completely redecorate it without your permission. I also tell you that you have to stay in your room at all times so I don't have to see you. This is why Christians have a problem with this narrative. This nation has always been predominantly Christian. Our many liberties come directly from biblical principles.
americans combine the notions of christians and liberty so intimately in their minds that it is impossible for them to conceive of one without the other.
alexus de tocqueville 1835
You're a smart guy, right? You have all that fancy schooling. So, tell me you get this.
Finally, if you would, please expand on your comment: "Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other."
I'm curious on who you consider "moral and religious" and what we should do with those heathens who aren't
We all have a God given conscience which tells us right from wrong. I think anyone is capable of being moral, at least to a point. We're all equal in Gods eyes, and that is the way it should be in this country. I am not interested in establishing a theocracy; that could only work if Jesus returned. This whole idea though of no government endorsement of Christianity is ridiculous. It's ingrained on our monuments, written on the walls of all three branches of government, stamped on our money, and is deeply rooted in all aspects of our history and culture. You cannot seperate the two. We've already seen the shocking moral decline that America has gone through in its departure from biblical morality. This is evidence that if you try to rip out the foundation, the whole thing will crumble.
