Absolute Ethics

Monday, August 29th, 2011

Joel Marks ‘Confessions of an Ex-Moralist’ came to me via Jean Kazez.

Another attempt to “derive ‘ought’ from ‘is’ ” is provided by CamelsWithHammers who identifies “goodness” with “effectiveness” at enhancing the “function” of a being. But his use of the word “function” (rather than something more neutral such as “effect) seems to beg the question by implying value before deducing it.

And in cases where the function of a being is not unique,the goal of enhancing the effectiveness with which a function is performed raises the question of how to weight the competing interests of different functions of the same being.

As an example of this, consider your case of the river.It is effective at several competing functions – transport of precipitated water back to the ocean, carving valleys, filling other valleys and deltas with silt, providing habitat for birds and fishes, etc,etc,etc. Now ask whether drilling a tunnel to bypass a long sweep of the river around a massif (which enhances the water flow at expense of carving), or building a dam (which enhances bird habitat at the expense of some kinds of fishes) is “good for” the river. How can you answer these questions without imposing some relative value on the different functions? And from where can you find that relative value except in your own preferences? (or appeal to authority, the choice of which is really just another expression of personal preference)?

Learning by Trial-and-Error

Monday, August 29th, 2011

Steve Jobs is one example of the general principle that learning and problem solving occurs most efficiently via a process of successive approximation or error-and-correction. I know that, for me, the solution of a math problem generally proceeds this way, and I suspect that, for those who are less successful, the problem is less with capacity for generating ideas than with lack of willingness, first to take the risk of being found wrong, and then of accepting one’s wrongness and abandoning a false idea.

The Lesson of Adam and Eve

Tuesday, August 23rd, 2011

Sean Carroll of the Cosmic Variance blog at Discover Magazine claims that the “Fall” of Adam and Eve is “a terrible lesson on which to found a system of belief”

On the contrary, it is a wonderful “lesson on which to found a system of belief” because its flexibility of interpretation demonstrates to any with eyes to see the vacuity of the entire concept of a “system of belief”.

In fact, the religion Carroll claims to want want – and just about anything else anyone else might want as well – is a legitimate interpretation of judaeo-christian mythology. So long as we don’t confuse the search for truth with the claim to have found it, then the search for truth and defiance of authority are not in conflict with the idea of the “forbidden fruit” being “knowledge of good and evil”. The only justified claimant to such knowledge is identified as “God” (who probably does not exist), and to claim his authority, ie to “take his name in vain”, is not only presented as the fundamental source of human suffering, but is also explicitly forbidden in another of the Hebrew books and is also a recurring theme in the Aramic/Greek books where “Jesus” frequently rails against religious “authority” and proclaims “judge not lest ye be judged”.

What is the True Essence of Humanity?

Wednesday, August 17th, 2011

In this post at Discover Magazine (referencing a New Yorker article on Svante Pääbo), Razib Khan suggests that “Perhaps the difference between Neandertals and behaviorally modern humans was less about large between group differences in individual level traits, and more about the fact than Neandertals simply lacked the leadership cadre which behaviorally modern humans possessed“.

One of the other commenters beat me to it, but I too am inclined to suggest that perhaps what distinguishes “humanity” (from eg the apparently more cranially endowed Neandertals) is the “capacity” for suppressing one’s own intellect and immediate interests in favour of some socially determined doctrine and leadership. Perhaps this does lead to greater reproductive success for individuals who can affiliate with such groups, and perhaps those of us who are too “bright” to be fully “human” might then be well advised under most circumstances to mimic the general dimmness rather than fail the test of credulity and get pruned as  defectors from the common interest.

Huh?

Tuesday, July 12th, 2011

Here is how people who consider themselves especially rational behave:

Person A does something which person B finds discomfiting. She says so and (without identifying A) publishes a request that others refrain from such behaviour. Howls of outrage (mostly anonymous blog comments) are directed at the unknown A on the basis of unfounded interpretations of his intent which were not explicitly alleged by B (although she did say that suspicion of such was what motivated her discomfort). More howls of outrage are directed at B, and person C publicly expresses a dismissal of B’s concerns. Person B publicly responds to C by name and objects to the dismissal. More howls of outrage either at the offense of C or at B’s response (for having the indecency to respond publicly to a public rebuke). Famous person D, having had plenty of time to come up with a considered and humane response which might calm the waters, decides instead to post a derisive attack on B’s right to express discomfort by sarcastically comparing it with others’ more serious problems, and when asked for a retraction chooses to elaborate by saying that B had no reason to feel any discomfort at all.  More howls of outrage against all of the participants. Person B expresses offense at D’s attack and responds by withdrawing her approval and support of him until he apologizes – and urges others who agree with her to do likewise. Person E calls this “vile” and a “character assassination” of the wonderful person D and characterizes it as “unskeptical” (apparently confusing skepticism with niceness and not understanding that it is a word which applies to opinions not behaviours). More howls of outrage on all sides, while outside the teacup real stuff is happening.

Personally I have no stake in the social environment of skeptics conventions and no interest in correcting every insane blog commenter, so if it weren’t for Richard Dawkins’ problematic involvement in the issue I probably wouldn’t have given any of it more than a moment’s thought. But when someone of his stature appears to behave badly it prompts more serious consideration of what the proper standards are.

I believe that any person has the right to say what makes them uncomfortable and ask for it to stop, so long as their request does not intrude unduly on others. Others may decide to accede to the request, or not. And it is reasonable to explain one’s response. But it is not reasonable to publicly belittle a reasonably and unintrusively expressed concern, nor is it reasonable to deny the existence of a bad feeling in another person since we have no reliable means of measuring the existence or extent of their distress.

What is “undue” intrusion is of course a judgement call, but
Watson’s original “elevator guy” message was made in her own space and did not intrude at all. Perhaps if it had been made during a conference presentation on another topic it might well have been judged “unduly” intrusive, but what was expressed in that more intrusive way was something different. It was a response to a pattern of responses to the original complaint which, in Watson’s opinion, was sufficiently serious to warrant the intrusion of bringing it up in the way she did. Public debate as to the appropriateness of that intrusion has been extensive and inconclusive but has no bearing on what follows.

Dawkins’ belittlement of the original concern was an inappropriate attack. (It would have been fine to disagree with Watson about the need for responding as she did to the responses, or with some of the allegations of sexism in Meyers’ post and comment stream, but not to do so by attacking Watson’s *original* concern). This was compounded by his subsequent denial of any harm at all (“zero bad”) associated with the expressed discomfort which he had no way of assessing.
So in my opinion there is nothing inappropriate in Watson’s demand for an apology.

Come to think of it, I guess he owes me an apology too – on account of the time I have wasted thinking about all this.

The Uses of Philosophy

Wednesday, July 6th, 2011

A bit of a coincidence today as John S Wilkins returns to the theme of scientists’ disrespect for philosophy at the same time as Chris Hallquist announces that philosophy is dysfunctional.

I suspect that the root of the problem is in the apparent claims of some philosophers to be finding “truth” – which is hard to credit when they consistently fail to find common ground on just about anything.

The value of reading and doing philosophy to me is not in the “answers” but in (some of) the questions and, to a lesser extent, some of  the arguments. These may not actually solve anything for me but, like poetry or literature they may colour the attitude with which I approach real problems.

 

 

 

Citizen Surveillance

Thursday, June 23rd, 2011

I tend to agree with Stephen Downes that there is nothing wrong and much to be admired in the use of social media to record criminal acts and bring the perpetrators to justice. And I particularly object to Alexandra Samuel‘s apparent agreement with referring to those who do so as “douchebags”. But the line between bringing to justice and punishing by public censure can be important if there are either possible mitigating circumstances and/or the censure remains public record for an excessively punitive duration, and/or when the behaviour is offensive to some but not illegal,and so on. As one who generally favours open access to information I tend to have little time for privacy concerns but I have to admit that sometimes they do have a real basis and the question of how to address them deserves some serious consideration.

How to find the equation of a quadratic function from its graph :: squareCircleZ

Wednesday, May 18th, 2011

Murray Bourne of squareCircleZ has posted on ‘How to find the equation of a quadratic function from its graph‘. This is indeed the type of discussion and exercise that we need to see more of.  Not only does it promote a deeper understanding of the mathematics than the reverse but it is also relevant to more practical applications. Occasionally we do come up with a formula and want to see what it looks like but, especially when it comes to specific examples as opposed to general patterns, it is more often that we have data and want to find or verify a formula.  One of the activities in my own “Blue Meanies” game (at http://qpr.ca/math/applets/meanies/ )asks students to “guess” the equation of a parabola through three points by imagining the curve and using its geometry (in various ways) to determine the equation. Of course in such “modelling” problems, with limited data there will be many possible model types that can be used, and there is an interesting interplay between fitting with a particular class of functions (eg polynomial or exponential) and giving reasons why one or other such class might be more appropriate in a given situation.

The Escape of Osama Bin Laden

Tuesday, May 3rd, 2011

In retrospect it is obvious that the mission had no hope of success. Obviously anyone with the resources available to Osama bin Laden, when building a special-purpose hiding place, would have included an escape shaft from his apartment which led to a subterranean bomb shelter with a tunnel connecting it to the outside. At the first appearance of US helicopters OBL surely walked into the escape closet climbed down the shaft to his bomb shelter and by the time that the SEALs had fought their way up to his apartment he was well on the way down the half kilometer long tunnel from which he climbed out at an unknown location on the bank of a nearby gully or river. Good luck finding him now!

Kenny Felder who I “met” as an appreciative user of my GraphExplorer applet has written a number of Essays and Commentaries that I find quite interesting.

Was Montaigne the First Blogger?

Saturday, February 26th, 2011

Ian Brunskill’s review of Sarah Bakewell’s recent book about Montaigne ends with “Montaigne was happy in a way that no blogger ever could be. There is, in the end, something to be said for the little room behind the shop.” This seems to me exactly wrong (not to mention being insufferably presumptious about the feelings of others). In fact thousands of bloggers like me are quite happy in our own little rooms with neither expectation nor fear of being heard by others. …more »

Rodney Dangerfield Award

PLENK10: PEL vs EPL

Memetic Allergies and Mutations

Saturday, August 14th, 2010

Ruth Howard asks Is Critical Thinking a Meme to Counter Memes? (in a post which came to my attention via #CritLit2010). And then she goes on to suggest that some skeptics become inflamed and hyper-sensitive when exposed to allergenic stimuli such as conspiracy theories (or at least that’s how I interpreted her juxtaposition of so many interesting analogies and ideas). I suspect that the biological metaphors are getting mixed here, but I get (and like) the idea that, in their hyper-enthusiasm for debunking some kinds of nonsense, people such as Brian Dunning in his “Here be Dragons” video go overboard to the extent of failing to apply critical thinking to their own position.

Ruth’s comments on Dunning’s video are apt. I was dismayed on seeing it myself at the manipulative presentation, including, for example, the frequent juxtaposition (to sinister sounding music yet!) of items representing real fraud or nonsense with others on which it is only fair to say that the jury is still out.

The Top Five Lies (about AGW)

Friday, August 13th, 2010

Discover Magazine is asking for readers to suggest their candidates for the Top Five Lies About Global Warming.

Here are my suggestions:

1. It has recently been proved
(False – it was “proved” in the 19th century by Svante Arrhenius. Yes there were gaps in the “proof”, and some imaginable mechanisms for the climate system to evade it, but they were always far fetched, and foolish to put a high stakes gamble on)
2. Evidence matters
(False – looking for evidentiary proof is like asking for such proof that you will eventually ht the ground after falling off a cliff and arguing about whether the fact that air resistance is reducing your acceleration means that you’ll actually be just fine)
3. We can all make a difference by changing our own lifestyle
(False – it will require universal collective action. So far, just 20% of the world have been “defectors” from abstinence and even with an 80% “participation” rate the strategy of living poor isn’t working)
4. Energy efficiency is the solution
(False – even with 100% efficiecy of all devices, with currently available of foreseeable energy sources there is no way we can continue to do what we do without causing more global warming)
5. Reducing our energy consumption is the solution
(False – Even compulsory mandated limits on travel and other forms of energy consumption would not suffice unless those limits were low enough to reduce us all to a “third world” standard of living. If we lower Western/Northern populations to any acceptable standard of living the effect would be more than offset by what would be necessary to raise all the rest to that same minimum standard.)

So what WILL bring AGW to an end?

Plan A is an immediate compulsory global one-child policy which will halve our population in about 50 years and cut it back to about 2.5 billion by the end of the century,
and if that is considered too draconian there’s always…

Google and Verizon

Monday, August 9th, 2010

Stephen Downes and Jay Hathaway are upbeat about this, but I share the doubts expressed by ‘saltrix’ and ‘Alain’ on Jay’s posting, and by the critics quoted in the NYT’s more recent article. Namely “protecting the internet” won’t mean a damn once there’s a new “differentiated” network on which the anomaly of relatively cheap publication costs for small independent sources can be done away with. At present the internet is supported by the traffic of big and small transmitters, but if the big ones leave it may get squeezed – and if the big corporate entities find it more congenial to ‘competerate’ with one another rather than with the less predictable challenges afforded by upstarts, then squeeze they will.

New Web Host

Sunday, August 8th, 2010

For some time I have been looking forward to the arrival of WordPress v3 which, among other things, enables easily setting up a separate blog for the CMR website. But to install it I needed my host to run a more recent version of MySQL than I had currently available. It turns out that they could do that, but that the process of transferring my database would be no less complex than taking my hosting business to a new provider whose interface I find more compatible and whose price is a lot less also.

So, after a week or so of email exchanges with webnames.ca (where the staff were always polite and helpful but the interface repeatedly defeated me), interspersed with productive work on a new “free trial” site at dreamhost.com, I have decided to go with the latter. And after one last slight unexpected delay in getting the DNS change recorded it seems that everything is now being served from the new host – including the new blog-of-its-own for CMR and an up-to-date installation of Moodle (into which I have been able to upgrade the old work I was doing re inclusion of editable graphs and dynamic math in quizzes).

Do we really need these “new agnostics”?

Saturday, July 31st, 2010

The rise of the new agnostics. – By Ron Rosenbaum – Slate Magazine. is a childish rant against the so-called “New Atheists” based on the canard that

Atheists display a credulous and childlike faith, worship a certainty as yet unsupported by evidence—the certainty that they can or will be able to explain how and why the universe came into existence. (And some of them can behave as intolerantly to heretics who deviate from their unproven orthodoxy as the most unbending religious Inquisitor.)

Faced with the fundamental question: “Why is there something rather than nothing?” atheists have faith that science will tell us eventually.
