Hansen on global warming

"It's hard for people to realize that climate is an emergency."

Conservatives write ELCA policy on homosexuality.

The Task Force for Sexuality Studies in the Evangelical Lutheran Church in America has issued its "Recommendation on Ministry Policies". According to a Worldwide Faith News report,

"If steps one and two are accepted, step three asks the assembly to commit to implementing steps one and two "in such a way that all this church bear the burdens of the other, love the
neighbor, and respect the bound conscience of any with whom they disagree." According to the report, "decisions about policy that serve only the interests of one or another group will not be acceptable."

Step four presents a proposal for how the ELCA could move toward change "in a way that respects the bound conscience of all," said the report. The fourth step is different from the previous steps in that it is "not simply a commitment in principle, but makes a specific recommendation for flexibility within existing structures and practices of this church to allow for people in publicly accountable, lifelong, monogamous, same-
gender relationships to be approved" for professional service in the ELCA, stated the report.

I often find it useful to compare the philosophical underpinings of contemporary, "unsettled" issues to the "settled" ones of yore. Mentioning "Hitler" is probably still too incendiary in this day and age, so I look at the issue of slavery.

The issue of a change in sexual ethics could have been taken two ways. One, they could have taken up an issue of "personhood"-- and stated that God requires us to change our ways and accept all persons as fully part of God's table. Perhaps some pretty effective law and gospel appeals could have come from that. But you might have to call out folks as being "sinners", even if you meant the prejudiced ones. In so doing, they would have been purely in the philosophical tradition of the abolitionists and civil rights advocates.

Another tack, the one taken here, is the honoring the "bound conscience"s of all. I'm hearing that the Recommendation takes on a philosophical underpining of affirming every one's conscience. And in so doing, it took on hook, line, and sinker, the argument of the slaveholders, who wanted a local option. The holders wanted everyone to "I trust people.". In the words of Scrooge, "I wish to be left alone." I'll say that politically, and spirituallly, this philosophy is an anathema to me. It's not the philosophy I read in the confessions or a Theology of the Cross or of all the great "busybodies" in the history of the church triumphant, with folks like Bonhoeffer and Dr. King coming to mind.

Improvements in flocking algorithm

This post represents improvements after multiple iterations in my flocking algorithm. I fixed a bug where my "maximum" acceleration was actually coded as a minimum acceleration. I removed the drag component outright, and spent some time tweaking the various parameters of avoidance strength and maximum acceleration. I even put in a counter to track the closest that two particles ever come to each other.

This animation represents a flocking simulation done with 150 particles across 400 frames in povray. It has a pretty nice feel for gracefully avoided near-collisions.

Accusations of religious totalitarianism (by philosophical totalitarians)

Imagine for a moment a Muslim cleric or imam living in rural Iraq or Afghanistan. He takes seriously to heart all of the Koran, especially those passages which cause him to live a self-examined life. A large measure of the demands he sees from the Koran are to life a life of charitable acts and self-control. He believes all of it to be literally true, and the only true revelation from the Power that Created the Universe, whom he calls Allah. He strives in the public square to make a case for his religion as part of respectful dialogue with his friends of other religions and sects. He believes them all to be 100% mistaken.

What does the ELCA say about this guy? He's a terrorist.

Granted, this is not what every pastor or pew-sitter of the Evangelical Lutheran Church in America believes. Hopefully, it's not what even a small fraction believe. But it is practically what was said in a podcast by the radio ministry of the Evangelical Lutheran Church in America, "Grace Matters". The episode is entitled, "The Dangers of Religious Totalitarianism". In the name of advancing respect for those of other faith traditions, the podcast took a hard tack on the topic of religious totalitarianism versus religious pluralism. Elements of totalitarianism was defined as believing other religions are wrong.
Host Peter Marty says:

"People of this or that persuasion convince themselves that they have the truth on various matters. They may stop listening to others of a different mind or faith, simply because they cannot fathom there's a way that anyone else could possibly have an angle on the truth.

This is why Islamic absolutists, or those Muslims with a totalitarian mindset, to use Eboo Patel's phrase, blow up the mosques of other sects within their own world of Islam. It's why certain Christian absolutists, or totalitarian minded Christians, have been known to blow up abortion clinics served by Christians of a different perspective than their own. "

I find Rev. Marty's position to be completely untenable. If I disagree with people, does my conviction of my rightness mean I have to go kill the erants? The number of cases in our everyday life where we know we have a unique angle on the truth, from observations in science to knowledge of a slippery spot on the floor, and we may see a need to "convert" others to our worldview, lest they slip on the floor. We may also have a conviction about human freedom, that people may walk where they may after you warn them, perhaps in the way a parent might need to teach a child an object lesson. But there can be no debate over whether there is a spot on the floor. Some questions are not open to existential debate. Asserting that a spot exists is not the same as shooting those who walk on the spot we'd identified.

Blog housekeeping

In looking at the Google Analytics report for this web site, I learned that one of the most popular pages on the blog was a reference to a web-based service that no longer exists. I offered a short discussion of the service and provided a link to it. (I fear that if I say anything more specific about the service, then this post will generate hits from Google's search engine.) In the interest of giving everyone who visits this site or uses Google a fun ride, I have removed that post from this blog.

As you were.
