Braxton Hunter's 10 questions for atheists

Apologist Braxton Hunter posed 10 questions for atheists, and in a slightly idle period, I thought I'd respond.

1. What facts about the real world does your personal worldview account for that mine as a Christian doesn’t account for?

My worldview (weltanschauung) is derived from my experiences, education, secular society and indigenous culture. I have advanced degrees in biology and decades of field experience on different countries. From my perspective, Christianity has been a complete failure at explaining the authenticity of native people's religious experiences. And the divided opinions on the different branches of Creationism tells me its failed to explain the diversity and distribution of life on earth. 

Nonetheless, I don't know what your particular Christian worldview holds, but if it subscribes to some of the more popular science-denying branches, I'm good sticking with mine. 

2. If your definition of atheism is merely that it's a lack of belief in God, and you're just waiting to be convinced, but then you speak of Him as though He's in some way synonymous with Santa Claus, the Easter Bunny or Fairies, doesn't that at least send the message to your listeners that you actually believe that there is no God?

I let people who call themselves atheists, define atheism for themselves. I don't expect agreement with any others. Personally I have concluded that deities do not exist, that yours was concocted very late in human history by a minor ancient Near Eastern tribe, before it got promoted to the chief deity of a slave-owning society.  For me atheism is not "a lack of belief in deities" but I don't assume that's the same for all. 


3. Do you see why supporting things that believers see as sin upon becoming an atheist might make those believers think that played some role in your adopting an atheistic worldview?

I disagree that there is an atheistic worldview. Atheism is a product of worldview that often, draws on knowledge of your religion's past and comparative religion, a preference for acquiring knowledge via scientific methods rather than revelatory and the support of secular moral philosophy over religious dogmas. From this worldview, atheism is often the result. After all, it encompasses only one issue whereas a worldview encompasses far more.  

I didn't become an atheist. There was never a transition. Your deity never seemed any more real than my native Atua (dieties) or the gods of ancient Greece. And was a lot less interesting to be honest. I've always been an atheist.

I might add that the Christian conviction in sin, drove them to suppress many of our pre-colonial beliefs and practices as these were regarded as sinful. So I am not bothered by what Christians now think of my support of these things. 


4. Exactly what probability do you assign to the proposition that gods or God in particular exist?

My Bayesian prior is 0. Humans lived as hunter-gatherers for about 200,000 years. Over much of the time we were animists (my own indigenous culture still has a strong grounding in animism). Deities really do not appear until after the human agricultural revolution and both High Gods and Moralising High Gods take centuries to appear. Deities are thus an outgrowth of our hardwired beliefs in animism. Nothing I've encountered about Christianity has caused me to revise upward this prior.

5. Does it bother you or worry you that non-theistic cosmologies offer unlikely-sounding or poorly specified explanations of the origins of the universe?

I disagree that say, a quantum perturbation acting on a super-hot, super-dense, minute particle is poorly specified. Nor does it seem unlikely, especially relative to a virgin-mating bloodgod conjuring it into existence.

6. Of the arguments for God’s existence, is there one that to you seems more interesting than the rest? Do any of them weigh in favor of theism?

None. Gods are the invention of ancient peoples and have earned no more credence than any other fantastic ancient creature from this period. 

7. What sort of evidence, if any, would be enough to convince you? (Let’s take experimental reproducibility off the table.)

There's two tests that come to mind. The Thomas test- a physical manifestation of Jesus in a personal encounter, down to being able to examine the wounds on his body or the Bruce Almighty test- a temporary gift of some of your deity's divine powers. 

8. To what extent did social and moral issues start you down your path to atheism?

Creationists often force biologists to take a position on deities. It was clear I couldn't be neutral in the face of their rank dishonesty. 

9. Can you name the last three academic books by theistic authors you read on the subject? How long ago did you read them?

What do you mean academic book? Last book that has any impact on me was Dietrich Bonhoeffer's Letters from Prison. 

10. If you knew that Christianity were true, would you accept God’s authority, repent of your sins, and trust Jesus as your king?

That's quite the loaded question and irrelevant! There is no overt act of rebellion going on here. I consider my own nature gods more plausible than your Near Eastern god of blood and death, and I know my deities don't exist. Gods are human constructs.  

If you want people like me to conclude your deity exists, then you need less loaded or leading questions. Try accepting that people have carefully considered your religion's claims and honestly found them unconvincing.

Whip it, whip it good

One of the cruelest legacies of the Abrahamic religions, was the normalisation of slavery.  Slavery in the Western Christian world persisted largely until the 1800s. Islamic countries did not ban slavery for the most part until the 1900s.  Even then it survived in extremist groups as with Islamic militias in Sudan or ISIS in Iraq and Syria.

This slavery presents a major problem for theists.  It is in direct conflict with a range of claims. These include the moral character of their prophets.  Abraham owned slaves. Mohammad owned slaves. The benevolence of God of Abraham and the origin of morality with this deity, does not survive the reality of slavery.

Christians throughout history have used two main arguments to defend slavery.  These are that their version was more humane, and that slavery was in some sense, a necessary evil.

The Nice Version of Slavery Argument.

This is often seen in pop-apologist defenses of ancient Judeao-Christian slavery.  Apparently all slavery in the ancients kingdoms of Israel was voluntary debt-bondage, of limited scope (rolls eyes).  There's nothing wrong with slavery therefore, if it is practiced by ancient Israelites or Christians.

This is a completely made-up argument. The OT rules on slave ownership make it clear manumission-guarantees were limited to Jewish males. Foreign slaves did not get the right to be freed after 6 years. The OT also describes slaves taken in warfare. Exodus 21:20-21 contradicts alleged humane nature of this ancient slavery by sanctioning the beating of slaves, and more explicitly, defining them as property rather than human beings.

Despite many Christians today wanting to distance themselves from pro-slavery arguments, this 'nice slavery' defense is echoed in later centuries. The motif of the kind slaver-owner, solicitous of their slaves' welfare, was commonly employed to defend slavery.
"We ought to consider whether the negroes in a well regulated plantation, under the protection of a kind master, do not enjoy as great, nay, even greater advantages than when under their own despotic governments" - Michael Renwick Sergeant
This tries to justify slavery as welfare-enhancing. While slavery isn't a good thing per se, the slaves are better off than in their own countries.  Or even better, by being exposed to Christianity they would become Christian and so, save their souls. Slavery was a small, temporal price to pay for an eternity in heaven. And with such justifications, moral slippage occurs.
The blunting effects of slavery upon the slaveholder's moral perceptions are known and conceded the world over; and a privileged class, an aristocracy, is but a band of slaveholders under another name.
- Mark Twain A Connecticut Yankee in King Arthur's Court


The Necessary Evil Argument

This argument is duplicated by slavery apologists, both modern and historical.  Arguments from the 18th (and 19th Centuries in antebellum US) were that slavery had benefits. It civilised or Christianised the barbaric and pagan peoples of Africa.  

The blacks are immeasurably better off here than in Africa, morally, socially & physically. The painful discipline they are undergoing, is necessary for their instruction as a race, & I hope will prepare & lead them to better things. - Robert E Lee. 
Modern apologists do not balk at similar arguments. Slavery was necessary for ancient societies and economies. 
Noting that Jesus did not instruct followers to abolish slavery ignores the fact that slavery was often voluntary and civil and a component of societal functioning in Biblical times - Pop-Apologist Stephanie Thomson
I note that there are other forms of 'unfree' labour that ancient economies could use instead. Ancient Egypt and China used a corvee system of mass labour conscription in agricultural slack-months, to undertake public works.  And while slavery did exist in Ancient China, there were attempts to abolish it. The Han emperor Wang Mang did so in 9 CE- during the lifetime of Jesus. Serfdom in various forms was also possible. Slavery was not necessary.


But wait, Christians ended slavery

It seems always odd the Christians also want plaudits for ending slavery in the West.  While I appreciate the efforts of all who were involved in abolition movements, the reality is they were also strongly opposed by Christians. Some were still defending slavery when the Federal Army's guns reached Richmond.  Most people for much of Christendom's history, were not like Wilberforce.  

One thing that also struck me is how much the abolition arguments emphasised the cruelty and brutality of slavery, rather than Christian arguments for ending it. It seems odd that if the argument against slavery really was theological, that this was employed so rarely. 

The problem is also that Christians had to end slavery because no-one else could. They had the political power in the West. It wasn't the Atheists or Buddhists in Western countries that could abolish slavery. They had no power to do so.  And when slavery has been legal for say, 90% of your religion's history, it's not earning the religion much credit to finally abolish it. That's taken far too long and the agonising suffering slavery produced reached too great a scale. 


Summary

It seems ironic that modern apologists use arguments that mimic those from people they claim to oppose.  The Trans-Atlantic slave trade was terrible. Antebellum slavery was not wonderful. Both were defended by Christians for centuries. 

Overall, I find the arguments defending historical slavery inadequate and unconvincing.  They lack a proper moral justification.  It seems instead they require a degree of moral slippage that people outside these faiths, would balk at. In ancient times, few had the courage and moral character to seek the abolishment of slavery. Moses, Jesus and Mohammad were not among them.  I cannot reconcile slavery with the alleged morality of the Abrahamic prophets and deity.

Atheism and the meaning of life

I had a recent conversation on Twitter with a Christian on whether my life has meaning.  Many such theists seem to believe that life can have no meaning for atheists.  The fact that we can be out there, enjoying life and the experiences it offers, seems impossible for some to grasp.

Problem 1: The Permanence Assertion


The first problem is that argument is built on an assertion. The assertion is that an experience has to be permanent for it to have meaning.  The assertion is never proven, it is obstinately accepted by fiat by the theist.  Yet, I know that holding my daughter the moment she was born, was an extremely meaningful experience. It still provokes a powerful reaction in me. That eventually I'll be dead, does not alter the fact that I felt something real, that it did have meaning for me. It doesn't have to be a permanent experience to have meaning.

If I don't have the belief that permanence is a prerequisite for meaning, it's not enough to keep repeating that assertion. You need to produce a strong argument, not insults, to establish it.  I've never heard such an argument.

Problem 2: An eternal afterlife makes this life meaningless


This can be established by comparing the different outcomes under different assumptions about an afterlife.

Lets suppose however, that each experience in Heaven gives a payoff of B, you average an annual level of happiness of b when you're alive in the mortal realm, and that each torment in Hell gives you a payoff of -H. With Heaven being superior to this life, and Hell being worse, let's simply say the B > b > -H.

Both Heaven and Hell are eternal, and thus provide you with an infinite benefit (or harm) stream.
Hence the actual payoff to being in heaven is ∞B and the payoff to being in hell is ∞(-H). With these being infinite streams, then the B and and -H is not really relevant. Heaven has an infinitely positive good payoff, Hell an infinitely negative payoff.  This is largely the logic behind Pascal's Wager. In that wager doesn't matter how unlikely you think Christianity is true, you will always win by being a Christian (or feigning being one).  The size of the payoff completely dominates the probabilities.

Your earthly existence, assuming you generally enjoyed life, has a payoff of tb, where t is the number of years you lived.  This has to be finite. Nobody is immortal.

So the ratio of payoffs of of your mortal life to heaven is tb/∞, or zero (0). In short, your mortal life is such a tiny fraction of your total existence that all your earthly experiences vanish to nothingness. You may as well shuffle off to the afterlife as fast as you can.

If we change the assumptions to an atheist one, then there is no afterlife. All the afterlife payoffs drop to zero. Which means the ratio of payoffs to a mortal life, to the after life, is tb/0. With denominator being 0, the ratio is ∞.  In short, every experience now is of profound value when we recognise its finite. The only way life can have meaning, is if it is finite in nature.

Problem 3: the Omniscience Dilemma


It gets worse if the deity is omniscient (all-knowing) as is attributed to the Abrahamic god Yaweh. Now its not just short, finite life you face that produces meaningless. Because this deity knew before you were born, where you would end up after death. If you're Hell-bound, because say you voted for Hillary Clinton or had some gay friends, Yaweh knows you can't change anything to escape Hell. You'll exist for an insignfiicant fraction of time, before suffering horrible torture. The same argument applies to heaven. Life isn't really a test if your deity already knows you're going to pass and get to Heaven. What possible meaning can life have, if there's not a single thing you can change to avoid your eternal fate?

Summary


The argument atheists can have no meaning to their life is not based on rational deliberation. I suspect rather, it's based on being intimidated by mortality and hoping a pact with an ancient god will allow the theist to escape this. People do derive however, meaning from their lives in varied ways. Living according to the values of some ancient Near Eastern pastoralists doesn't really satisfy the goals of all.  Indeed, I'm surprised anyone finds it satisfying.

Let's Run

Introduction


This isn't so much a blogpost on running. It's a personal account, that includes running.  Maybe it's important. Maybe it's not. But it gives some perspective at least, on myself. If anyone is interested.

The Human Runner


The human body is well adapted to running. We have relatively long legs, a narrow pelvis, a valgus knee and a rigid toe.  Within the animal kingdom, we are superb endurance runners. Many of us can, and will run 42 km without stopping. Few animals can match that. We do it because its fun. We do it because it's a challenge.

I find running to be calming (running does produce good things). It gets you outside, the kilometers pass by your running shoes, for a time modern life is shut out.  You don't have to think, to interact, just settle into a rhythm and run.  You're out feeling the sun, or the wind, or the rain.  That inner African plains ape is released.

The Teenage Runner

I wasn't particularly athletic before then. I hit the teen years though, as family-life took a hit. It's somewhat too personal to go into here, and there's nothing unique about the teenage years being rough.  Still, one relationship has never recovered. Running was therapeutic. It was an escape.  I started to win races.

Later we moved. It was to a rural village. There wasn't a lot of things to do there. By the time I was 15, there were 5 other boys my age there. By the end of the year, only 2 of us were left alive.

J took the longest to die. He was smart. Really smart.  He was probably smarter than I was (and I've got a PhD so not lacking there). He got leukemia though. The bad kind. He withered away over the months and died.

His sister committed suicide a few years later.

I stayed in contact with his mother for years afterward.

K was also my age. A gangly kid teenage boy. Got on well with lots of people. He died suddenly. One day he was catching the bus to school with us. Then he wasn't. He swung some irrigation pipes over his shoulder at his farm. They hit power lines.

I never saw his mother smile again.

I wasn't close to the other two. They died in a car crash. Old cars, rural roads and teenage boy drivers aren't a good combination.  It was still a shock.  There were too many funerals that year.

I ran a lot. It helped. There was an isolated lake over some hills I could reach if I wanted to. I could disappear for a while. Feel the dry summer grass crunch under my shoes.  Feel the sun on my skin. I ran a practice marathon once, just to see if I could do it. And I got fast and fit. By the time I'd finished High School I'd got several athletics awards and cups.

I met the only other survivor of that year, G, years later at his mother's funeral. He was the one with the prison guard. He'd been let out for the occasion. He'd got fat. Teeth were missing. We locked eyes, but he didn't recognise me.  I remembered though.

I still think of J.  He'd already won scholarships at his age.  He should have lived. 

The Raw Runner

I'd got back from university for a summer break. Xmas had past. I was at  remote beach in NZ.  R was also there. Older than I was. Wife had died a bit earlier.  That was the catalyst.

He drowned himself. 

It was before cellphones hit the market, not that we'd have had coverage out there.  Getting to a landline took time. That sense of panic is still there, despite the years. It took 3 hours from the drowning, to when emergency services arrived at the beach.

That's not an optimal duration to be left with a dead body.

The nightmares started soon after.  Sleeping crashed.  Being asleep was worse than being awake.

I ran in the night instead. If you push your body to the limits of physical exhaustion, you can over-ride the brain. You'll get some sleep. My feet quickly got blisters. The blisters would burst or bleed. And I'd keep running.

After a while the insomnia wins. There are vast holes in my memory from that year.  I'd hallucinate stuff.

That was the first time I used therapy.  I was practically ordered to by the University.  There were things outside my friends' experiences. Outside their comprehension. It needed something for the experts.

Edit: I've only ever told one other person the full story of those hours at the beach. And that was my therapist. Nobody else really knows. Not my parents. Not my wife. I can't.  

I didn't stop running. But I eased back on the damage.

Everybody Hurts


I wasn't ignorant of what it was like to parent a child with a disability. My uncle R was born late in my grandparents lives. He had spina bifida. And significant intellectual impairment.   It was tough on my grandparents. It was from an era where there was little social support for such problems.  He died when he was a teenager.  As my parents were starting their family.  All that is left of him is a few scattered memories and a name on a tombstone.

At the very end, my grandmother would dream of him and her late husband. Despite the gulf of the decades, and numerous children, grandchildren and even great grandchildren, it was R she came back to.

Something is Wrong

He didn't talk.  That was the first sign. I read to him every night. It was part of the therapy. Sometimes my wife would come in to find us both asleep, book open in my hand. It exhausted us.

Along the way there was the trips to the hospital. The school years, when nobody ever invited him to a birthday party, or to hang out after school.  The sudden collapses and seizures without warning. You entered the world of MRIs, and of specialists. Of teetering on that edge of uncertainty of whether it was a terminal illness or not.  Of battling the system for the promised support, that never seemed to be as timely or as fulsome as promised.

And along the way, your friends and family find reasons not to visit as often.

Eventually you notice they don't come at all.

It's not just the people with disabilities who get marginalised, and pushed to the edges and cracks of society. Their families get carried along with them.

I like to run. It takes me back to those years when I was running as a teenager. That for a period of time, the world is calmer and simpler. I'm slower than I was then.  But the calm of eating up the kilometers in running shoes remains.

So I run.

On the side of the angels?

Or, a closer look at Morality

One of the popular arguments for deities (specifically the Abrahamic god) is based on morality.  This has always surprised me.  The argument that our morality is derived from this deity seems absurd.  The idea that we'd get morality from an ancient blood-god that commanded and committed genocide, seems, well, beyond ridiculous.  It's way out there in cloud-cuckoo land.

Nonetheless, it merits a deeper response. Many theists seem fond of it. I'm even accused of borrowing my morals from Christianity (rolls eyes).  One assumes if I was to borrow my morals from some other belief system, it wouldn't be one with a body-count as high as Christianity. Or Islam.

The argument roughly is that humans have objective morals, objective morals can only come from gods that need living creatures killed to deter its retribution, therefore this god exists.

1. Objective or Subjective Morals?

 The first problem is that a false dichotomy is created with morals. Borrowing from axiology (philosophy of values) it is asserted that locus of morality is either the object, or the subject.  If morality is objective, all the subject need do is recognise what is moral in that case. Morality is external to the subject.

If morality is subjective, the subject applies their values to the relevant case. It is thus the subject that determines if something is moral.  Morality is internal to the subject.

The crucial difference is that we would not disagree on what is moral, it it is objective.  It can't change. It's a property of that case.  We can only disagree if morals are subjective.

This however, is not the only way morals could be classed.  We could also distinguish that is authoritarian, and that which is rational.  The challenge for theists is explaining why their morality is objective, rather than authoritarian.

Let's illustrate. The bible contains the edict to kill witches. Exodus 22:18 - "Thou shalt not suffer a witch to live".  For centuries, thousands and thousands of people were killed by Christians for witchcraft. It continues in some parts of the world.  It is a merciless and cruel act, tragically based on a fictional crime.



It's clearly not an application of a subjective, or rational, moral philosophy.  If the only option is objective, then it must be the objectively moral thing to do.  It is also vile and repugnant. In truth, it is not objective. It is authoritarian. And for most of Christianity's history, it was also the right thing to do.  So, no, I don't borrow my morals from Christianity!

2. Do Objective Morals Exist?

What would it take to show that morals are objective?  This requires finding a moral rule that we agree is moral, but is inexplicable by other means.  I can conceive of a minimum of two tests.

a) The Evolutionary Test

Evolutionary biology provides several mechanisms to account for why humans would adopt rules and behaviours we would class as moral.  These include kin-selection and reciprocal altruism.  In addition, some behaviours can be Evolutionary Stable Strategies.  Their evolutionary advantages make them stable and are selected for in successful societies.

Parental care is easily explained by kin-selection mechanisms.  Charity toward others also appears to be an ESS.  Early human societies would have suffered from a lot of food variance.  Being willing to sharing food acts like an insurance policy for all. An unwillingness to share would be punished by others refusing to share. This would hurt the selfish during times they suffered food shortages.

In short, we expect certain rules and behaviours to be selected for because they are evolutionary stable or advantageous.  They benefited humans, in the communities they lived in.

b) The Rawlsian Contractarian Test

Rawls is not an explicit Contractarian. Rather he is a hypothetical Contractarian.  Whether a rule is moral or not, can be evaluated rationally by all parties. If the parties agree on the rule, it can be considered moral.  To prompt rational consideration, Rawls uses the veil of ignorance.  Nobody knows whether they will be the victim of such a rule, or a benefactor.  This ignorance forces everyone to consider everyone.

Hence, a Contractarian would argue that say, killing people for witchcraft or owning blacks as slaves, is immoral.  The parties would not agree such acts are moral out of concern they could be victimised by the rule.

This makes Contractarian rules, neither purely subjective nor objective. It makes moral rules a rational product of human societies.

c) Do such rules exist?

There are many Christian rules that fail the tests above.  The problem is they're also immoral.  Whether it is the public execution of non-virgin brides, or the killing of Sabbath stick-gatherers, they don't appear moral.

3. Objective Morals Don't Exist

The morality argument fails on its first premise. Objective morals don't appear to exist.  What is considered moral changes.  Our attitude to slavery has changed, in many parts of the world, so has attitudes to divorce, gay marriage, women's suffrage and capital punishment.  Applying the brutal and authoritarian morality of the slave-owners of the biblical era would get you arrested today.

These changes in morality are more consistent with an explicit Contractarian moral philosophy.  We debate what is moral. We try to consider the welfare effects not on us, but others. And what was once moral, like slavery, becomes immoral. What was once immoral, like homosexuality, is no longer.

4. Conclusion

The argument that the Abrahamic god is the source of our moral sense is ridiculous. It relies on a false dichotomy between objective and subjective morals. It confuses authoritarian, or evolutionary stable rules, as objective morals.  And it turns a blind eye to the atrocities undertaken, and commanded by the Abrahamic god.

Index: Brave Christians

I read and debunked SJ Thomason's (aka @lead1225 on twitter) "Brave Christian" argument for god, so you don't have to

Basically, it ignores contemporaneous martyrdom in other Jewish sects, provides a very low body count of early Christians, ignores natural explanations of Paul's vision and conflates an historic Jesus with the gospel Jesus.

The long versions:
Part 1: Not a fan of Carrier

Part 2: Will the brave Christians standup?

Death and Legend in Judea

Introduction


Well, Easter has come and gone again.  That seems to be a good time to talk about the resurrection. Because many Christians have been talking about it.  How else can we explain the empty tomb if Jesus wasn't magically resurrected via the power of an ancient bloodgod? It's the only explanation that makes sense! (rolls eyes)

The problem with the question is its loaded nature.  The empty tomb is presented as a fact. This has some major credibility problems.


Problem 1: Timing


The empty tomb isn't used as proof of Jesus' divinity and resurrection until we get to the gospels.  The  (genuine) letters we have from Paul do not mention it. Nor is it present in other early NT letters.  For something that's supposed to convince us all that Jesus was divine and resurrected, its absence for decades in early Christianity literature is astonishing.

The gospels are generally reckoned to be written after Jerusalem was besieged by the Romans (70 CE) because they're not referenced in earlier Christian documents. Paul seems completely unaware of them.  And prophecies of Jerusalem being sacked are always easier to make after the event...

The sequence for the gospels is usually reckoned as Mark, followed by Luke and Matthew, and finally John.  This spans around 30-40 years.  And all are long after the alleged event. The gap between when the empty tomb alleged occurred and when it's first mentioned is extraordinarily large.

Edit: this alone persuades me that the empty tomb was a later contrivance.  

Problem 2: Inconsistencies


Despite the synoptic gospels (Mark, Matthew, Luke) patently using the same sources, they can't keep the empty tomb story straight. Throw in John and it gets worse.  The number of women who went to the tomb, when they went, what they saw at the tomb, what they did afterward, whether they were believed or not are all inconsistent across the gospels.

The Apologist gambit is to assert that this is what we expect with eye-witness accounts.  No. It's consistent with a bunch of people who didn't balk at making things up to sell their religion.


Edit: the women are not the only inconsistency of course. E.g. Matthew has guards and a seal that everyone else seems to forget. The accounts are more what we'd expect with oral traditions and attempts to establish the orthodoxy or early doctrines over several decades.

Problem 3: It conflicts with Roman practice


As far as we can tell Romans did not normally allow crucified victims to get buried in tombs. Crassus left thousands of ex-slaves rotting on crosses after the suppression of the Slave revolt.  Normally crucified victims were left aloft to be picked clean by birds and the like.  

To be buried, and buried ceremoniously instead of in a common pit, is a deviation that begs for explanation.   


Edit: this is the weakest objection I have, and one that Richard Carrier has explained to my satisfaction. It is highly likely Romans allowed the locals to maintain their traditional burial practices. 

Problem 4: Joseph of Arimathea


It has always struck me how much of a Deus ex Machina Joseph plays.  In order to get Jesus from the cross, into a tomb and in the time available, requires a very powerful and capable character.  There's nobody in the disciples capable of pulling this off.

Enter Joseph.  He fixes all the problems with the plot.  First, he's politically powerful.  He's part of the council that condemned Jesus.  But like all superhero fiction, he has a secret identity.  He's also a disciple of Jesus.  He's influential enough to persuade Pilate to take the body off the cross.  He's also rich.  This is also necessary for the plot.  They have to buy linen cloth and 100 pounds of myrrh and aloe that evening.  He's also already got a tomb ready.   Every plot-hole (bar one) is immediately fixed.  Evening might be approaching when he asked Pilate for the body, but Jesus is lying in a shroud, in a tomb, with a stone covering the entrance in time for his resurrection. Phew!

The remaining plot hole of course, is there isn't enough time to get this all done in the time available. 

Joseph's appearance in the story is dramatic.  He's not mentioned in the gospels before this.  And he disappears just as dramatically. He's never mentioned again.  He's not mentioned in Acts, he's not mentioned in any of the letters preceding the gospels.  Paul, Peter and James have no recollection of him at all. He's a powerful and connected guy with massive influence, and nobody mentions him?! Amazing.  

Joseph only has one job.  He appears at exactly the right time to fill in a bunch of critical plot-holes, and then disappears.  He has the traits of a literary invention that appears decades later when the empty tomb story gets added to the Jesus legend- not the traits of an historic person. 

Edit: Even the locale of Arimathea appears made up. 

(If you want a much deeper analysis of Joseph of Arimathea, I recommend John Loftus' blog).


Conclusion


I don't feel that I need to explain the empty tomb, because I don't think there was one.  Early Christendom was plagued with doctrinal problems.  Hints of this are preserved in the letters of Paul, James and others.  This also created a range of heretical sects, such as the Arians.  

The gospels weren't written to be histories.  They were written to convince people that Jesus was the Messiah and of divine origin.  And by drawing on the authority of Jesus and the early disciples, they could be used to resolve doctrinal disputes.  Was the resurrection a mostly spiritual personal visionary event?  Or was it a physical event?  For anyone who believed in a physical resurrection, the canonical Gospels make a perfect argument. And they get more elaborate the later the gospel is composed. It's the last gospel, John, that introduces Thomas as the clincher for the physical resurrection. 

So either major scientific laws were broken to miraculously bring the offspring of an ancient god and virgin back to life.  Or the belief that the resurrection was a physical event evolved slowly in a community that was willing to add embellishments that showed this, in retelling, over decades.  It's not really difficult deciding what's the least plausible.
