EEG device detects consciousness in persons in persistent vegetative state

1 Comment

Here’s an interesting article from the New Scientist.

Excerpt:

Signs of consciousness have been detected in three people previously thought to be in a vegetative state, with the help of a cheap, portable device that can be used at the bedside.

“There’s a man here who technically meets all the internationally agreed criteria for being in a vegetative state, yet he can generate 200 responses [to direct commands] with his brain,” says Adrian Owen of the University of Western Ontario. “Clearly this guy is not in a true vegetative state. He’s probably as conscious as you or I are.”

[Owen’s team] devised a test that uses the relatively inexpensive and widely available electroencephalogram (EEG).

An EEG uses electrodes attached to the scalp to record electrical activity in the brain.

Owen and his team used an EEG on 16 people thought to be in a PVS and compared the results with 12 healthy controls while they were asked to imagine performing a series of tasks.

Each person was asked to imagine at least four separate actions – either clenching their right fist or wiggling their toes.

In three of the people with PVS, brain regions known to be associated with those tasks lit up with activity, despite physical unresponsiveness. This suggested to the researchers that the subjects were carrying out a complex set of cognitive functions including hearing the command, understanding language, sustaining attention and tapping into working memory.

“It isn’t the case that just because somebody doesn’t respond they’re not conscious,” Owen says. “There’s a growing body of data now demonstrating that many of these patients aren’t what they appear.”

The rest of the article talks about how the scientists are planning to use their new technique to communicate with patients by asking them to think of specific things which will mean “yes” or “no”. The long-term goal is to get the patients to be able to communicate, perhaps even allow them to move a mouse pointer by triggering reactions in their brains by using their thoughts.

I think this research dovetails nicely with the OCD research I mentioned before. Maybe now would be a good time to talk more about that research.

William Dembski discusses the OCD research of Jeffrey Schwartz.

Excerpt:

Schwartz provides a nonmaterialist interpretation of neuroscience and argues that this interpretation is more compelling than the standard materialist interpretation. He arrived at this position as a psychiatrist specializing in the treatment of obsessive-compulsive disorder (OCD). OCD sufferers recognize obsessive-compulsive thoughts and urges as separate from their intrinsic selves. For instance, after a few washings, the compulsive hand-washer realizes that his hands are clean and yet feels driven to keep washing them. It was reflection on this difference between the obvious truth (the hands are clean) and the irrational doubts (they might still be dirty) that prompted Schwartz to reassess the philosophical underpinnings of neuroscience.

From brain scans, Schwartz found that certain regions in the brain of OCD patients (the caudate nucleus in particular) exhibited abnormal patterns of activity. By itself this finding is consistent with a materialist view of mind (if, as materialism requires, the brain enables the mind, then abnormal patterns of brain activity are likely to be correlated with dysfunctional mental states). Nonetheless, having found abnormal patterns of brain activity, Schwartz then had OCD patients engage in intensive mental effort through what he called relabeling, reattributing, refocusing, and revaluing (the 4 Rs). In the case of compulsive hand-washing, this involved a patient acknowledging that his hands were in fact clean (relabeling); attributing anxieties and doubts about his hands being dirty to a misfunctioning brain (reattributing); directing his thoughts and actions away from handwashing and toward productive ends (refocusing); and, lastly, understanding at a deep level the senselessness of OCD messages (revaluing).

Schwartz documents not only that patients who undertook this therapy experienced considerable relief from OCD symptoms, but also that their brain scans indicated a lasting realignment of brain-activity patterns. Thus, without any intervention directly affecting their brains, OCD patients were able to reorganize their brains by intentionally modifying their thoughts and behaviors. The important point for Schwartz here is not simply that modified thoughts and behaviors permanently altered patterns of brain activity, but that such modifications resulted from, as he calls it, “mindful attention”-conscious and purposive thoughts or actions in which the agent adopts the stance of a detached observer.

It turns out that people can freely choose to exert “mental effort” in order to change what their brains are doing.

By the way, if you like this topic, and want a resource to show your friends, be sure and get a hold of the debate on mind vs. brain between Jeffrey M. Schwartz and Michael Shermer.

Polemics

Christianity and the doctrines of exclusivism, inclusivism and pluralism

Leave a comment

Are you familiar with the differences between exclusivism, inclusivism and pluralism? This article from Leadership University explains all three of them.

Here’s exclusivism:

The following is a succinct explanation of the central characters and ideas behind each position. The exclusivist position has been the dominant position of the church as a whole through much of its history until the Enlightenment. Major representatives include Karl Barth, Emil Brunner, Hendrick Kraemer, D.A. Carson, William Lane Craig, and R. Douglas Geivett.

Key to this position is the understanding of God’s general and special revelations. God is manifested through creation (general revelation), but Man has responded by freely going against this revelation and, thus, stands guilty before a holy God. However, God has demonstrated a reconciliatory mercy through His word and deed, fulfilled completely in Jesus Christ. The historical person of Jesus, then, is the unique, final, decisive, and normative self-revelation of God to Man (special revelation). Exclusivists believe that Jesus Christ is the sole criterion by which all religions, including Christianity, should be understood and evaluated. Calvin Shenk explains:

Christ did not come just to make a contribution to the religious storehouse of knowledge. The revelation which he brought is the ultimate standard. Since in Christ alone is salvation and truth, many religious paths do not adequately reflect the way of God and do not lead to truth and life. Jesus is not, therefore, just the greatest lord among other lords. There is no other lord besides him.

Specific texts often employed by exclusivists include Acts 4:12; John 14:6; 1 Corinthians 3:11; and 1 Timothy 2:5-6.

And inclusivism:

Inclusivism is a blanket term to characterize a sort of “middle way” between exclusivism and pluralism. Most prominent within mainline Protestantism and post-Vatican II Catholicism, its notable proponents (in one formor another) include Karl Rahner, Raimundo Panikkar and Stanley Samartha, and Hans Kung. Evangelical theologians such as Clark Pinnock, Norman Anderson, and John Sanders have also identified themselves with this position. Herein, the agnosticism associated with the latter option above is replaced with outright optimism. Christian salvation is not confined to the historical or geographic extent special revelation has spread, rather it must be available to all cultures, irrespective of age or geography.Salvation is still posited wholly in Christ and his salvific work. Specific knowledge of this work, however, is not necessary for the effect (i.e., salvation) to apply to those within a different religious culture who have responded to the general revelation available. Once again, Shenk explains:

Inclusivists want to avoid monopolizing the gospel of redemption. They acknowledge the possibility of salvation outside of Christian faith or outside the walls of the visible church, but the agent of such salvation is Christ, and the revelation in Jesus is definitive and normative for assessing that salvation. Jesus Christ is believed to be the center, and other ways are evaluated by how they relate to him. Other religions are not just a preparation for Christ, but Christ is actually present in them.

The fundamental differences between exclusivism and inclusivism… are the nature and the content of “saving faith.” The former emphasizes explicit faith while the latter points to an implicit faith.

And pluralism:

Finally, there is the pluralist position. This is undoubtedly the most difficult of the three to define in any general sense. The spectrum of pluralistic thought is as wide as it is long. The focusof this particular study will examine the contributions of its key figures: Paul Knitter, John Hick, and Wilfred Cantwell Smith. Just as in the previous positions, the interpretative range within just these three individuals varies. It is fitting, however, to focus primarily on them since they are the most vocal and influential figures espousing pluralism today.

Hick and Knitter argue the case for pluralism on the following grounds: (1) ethically, it is the only way to promote justice in an intolerant world; (2) in terms of the “ineffability of religious experience,” so no religion can claim an absolutist stance; and (3) through the understanding that historical and cultural contexts must be the filter for any absolute religious claim. Hick has argued that all world religions attempt to relate to the unknowable Ultimate Reality (or, the Real), but because of their various cultural and historical contexts these attempts are all naturally different. Hence the various conceptions of the Real and the salvation(s) sought. The common soteriological goal, toward which all religions strive, though, is rooted in the desire to transcend self-centeredness and, in turn, encounter a new (unexplainable) experience with the Real. But, he emphatically emphasizes the fact that there is “no public evidence that any one religion is soteriologically unique or superior to others and thus has closer access to Ultimate Reality.”

Therefore, with pluralism, Christ is no more definitive or normative than any religious figure or concept. Or, as Andrew Kirk explains, “Rather than confessing that Jesus Christ is the one Lord over all, this view asserts that the one Lord who has manifested himself in other names is also known as Jesus.” By “crossing the Rubicon,” as Hick and Knitter illustrate, Christians are encouraged to abandon any claim of Christian uniqueness and the possibility of absolute revelation, accepting the fact that the Christian faith is one among many options.

Now maybe you didn’t know this, but Roman Catholics seem to have taken a turn away from exclusivism and towards inclusivism in the last century.

So, I thought I would post a rebuttal to the Roman Catholic embrace of inclusivism from one of my favorite Christian apologists, Greg Koukl.

Excerpt:

There are some issues of Christianity that are intra-Nicene, intramural discussions between believers, in which I think a charitable person can easily see how another Christian can hold a different view because there are things that are difficult to understand in Scripture. For instance, though I’m Reformed in my soteriology, my understanding of salvation–I’m a Calvinist–I am sympathetic to an Arminian perspective because I can see how they, in lines of reasoning from the New Testament and verses themselves from the New Testament, can come to their view. So, though I would disagree, and I think they’re mistaken, I understand how they can see it.But there are other positions that I cannot understand because there is no New Testament evidence in favor of it, and, to the contrary, almost to a word, as the New Testament touches the issue, it says quite the opposite.

Earlier this week, I was honored, flattered, and, frankly, humbled to have a very unique opportunity on Monday to address an audience of about 150 Jewish people that were in the midst of Jewish High Holy Day services–morning services, evening services–at kind of a pause time in the afternoon, in which my host and I and another guest had a discussion about Jews and Christians. The three of us were on the panel:  my host, Dennis Prager, a man I have a tremendous admiration and affection for, and Greg Coiro, a Roman Catholic priest and a professional friend. I’ve known both of these men over 20 years and have been in many discussions, both in private and public on the air with Dennis and Greg Coiro.

It was in this opportunity that, in a sense, the ancient quarrel of sorts, theologically, was revisited, that I’ve had in the past many years ago when we were talking about this in interfaith dialogues. This difference of opinion is a historically new development in Roman Catholicism that stunned me when I first encountered it in the early days of being on Religion on the Line in the late eighties, a radio panel Dennis Prager hosted for many years. The priests on the panel uniformly held the conviction, informed by Vatican II, that Jews don’t have to believe in Jesus in order to receive the benefits of Jesus’ salvation. This is a view called “inclusivism.” It’s not the same as pluralism, but in my view, it seems to have the same impact: “Yes, Jesus is necessary for salvation, but you don’t have to believe in Jesus to benefit from Jesus.”

Now, at this afternoon panel recently, the very first question that came up was whether trust in Jesus is necessary for salvation. “Greg, do you believe that? Do Protestants believe that?” I answered, “Yes, I believe that. And no, not all Protestants believe that. But let me try to explain it to you in a way that doesn’t sound so stark. Let me try to give it some perspective.” I explained that it wasn’t as if God was up there looking down at a bunch of religious clubs and prefers some over others. He used to prefer the Jewish club and now He prefers the Christian club. It may sound that way to many when this doctrine of Christianity is put forward: Jesus is the only way of salvation; you must believe in Jesus in order to benefit from what Jesus did.

Talk about Daniel in the lions’ den. Anyway, click through and read the whole article to get an idea of how to make your stand for exclusivism in difficult places.

For a general article defending the Christian doctrine of exclusivism, check out this article by William Lane Craig. One of my favorites, from way way back to when I was an undergraduate.

And, if you would like to listen to a debate on pluralism, then here is a debate featuring pluralist John Hick.

Obama pleases environmental lobby by killing 20,000-job Keystone XL pipeline

Leave a comment
Obama Economic Record November 2011
Obama Economic Record November 2011

From the Daily Caller.

Excerpt:

Roughly 20,000 oil industry construction jobs are being thrown under Obama’s 2012 campaign bus, largely because the president needs to pump up his sagging support among the environmentalists.

The pitch came Thursday when President Barack Obama put his leadership behind a State Department plan to study alternative routes for the pipeline, which is intended to bring oil from Alberta in Canada to oil refineries along the Gulf Coast.

“We should take the time to ensure that all questions are properly addressed and all the potential impacts are properly understood,” said Obama’s afternoon statement.

The construction jobs, and the revenue from operating the Keystone XL pipeline, may now go to Canadian workers.

That’s because Canadian government officials are already planning to help build a competing pipeline from Alberta’s oil fields to new West Coast ports near Vancouver. The likely destination point is the port of Kitimat in British Columbia.

The U.S. Department of State will begun studying an alternative route for the Keystone pipeline, even though an earlier department study had concluded the proposed route is the best of several alternatives. The new study will delay any final approval until after the 2012 election, allowing Obama to boost his support among environmentalist groups, activists and voters.

But the delay may kill the U.S. segment of any pipeline, because the decision increases the environmentalist movement’s clout during any future round of approval disputes, and also spurs the development of a pipeline through Canada.

The job-killing decision was panned by GOP legislators and business groups.

“More than 20,000 new American jobs have just been sacrificed in the name of political expediency,” said a statement from Ohio Rep. John Boehner, the Speaker of the House of Representatives.

“This is clearly a political decision and everyone knows it… Politics has trumped jobs in this decision and we can only wonder if the Administration’s delay will cause Canada to turn their pipeline west and ship their energy and American jobs elsewhere,” said  statement from the U.S. Chamber of Commerce.

But the decision helps the Democratic-allied green-energy industry, which is now reliant on government subsidies to compete against the oil energy industry.

The oil that would be pumped through the Keystone XL pipeline would make gas cheaper for drivers, and worsen the competitiveness of the green-tech companies.

The stock value of green-energy companies, and their supply of commercial investment, has already dropped in the last several months because investment analysts believe an Obama loss in 2012 will prompt GOP legislators to cut federal subsidies.

Before his 2008 election, Obama predicted he would raise oil-energy prices to spur the green-energy industry.

The Wall Street Journal explains more.

Excerpt:

In April 2010 and again this August, State produced multivolume environmental impact statements that concluded the pipeline would have “no significant impacts” on the environment. That should have ended the matter.

But the President’s environmentalist friends have decided to make Keystone a test of his green virtue. “We’ll see if [Mr. Obama] is an oil guy or a people guy,” eco-agitator Bill McKibben recently warned at an Occupy Wall Street event, and the Sierra Club has threatened that it won’t “mobilize the environmental base” in 2012 if he approves the project. Various Hollywood worthies have marched in front of the White House in protest.

[…]We’re guessing this decision to abdicate was really made by President Plouffe, as in David Plouffe, the White House political aide who seems to be running most of the executive branch these days. The Keystone cop-out couldn’t be a clearer expression that this Administration puts its anticarbon obsessions—and Big Green campaign donors—above job creation and blue-collar construction workers. He’s President of the 1%.

This reminds me of the way that Obama hurt the economy by delaying three free trade deals for three years, in order to appease his union supporters.

When Obama tries to create jobs, he ends up doing thinks like giving $535 million taxpayer dollars to Solyndra – to repay his Democrat fundraisers. And then they go bankrupt, because green energy is a hoax. The right way to create jobs is by letting businesses keep the money they earn, and keeping government out of their operations. Unfortunately, Obama doesn’t like it when people earn money by selling services and products, and he thinks that government needs to regulate businesses. So, we are stuck with high unemployment.
