According to conventional wisdom (as expressed in 'Seriously,Science?' at discovermagazine.com):
We all know that plastic is generally terrible for the environment because it doesn’t biodegrade, and just sits in landfills.
But why is having carbon locked up in relatively small known locations (rather than oxidized and maybe even methanized into the atmosphere and/or distributed widely in micro-particles of unknown toxicity) to be considered as "generally terrible for the environment"?

I think I would define consciousness in purely computational terms and I don't think I'd make it dependent on the specific structure in which the computation takes place.
eg, perhaps: "An entity is said to be 'conscious' if its state changes according (at least in part) to a computational process in which the input data includes a partial model of the state of the computational process itself."

Dear Conservative Canadians,
I share the fear of masked figures that is common in our culture, and I am more inclined than most to be put off by overt displays of religious and other affiliation. But the attempt to reduce our political debate to the level of such feelings is so shameful that it must not be allowed to succeed.
For many the niquab is an imposed symbol of male domination, but for others it is a choice based on feelings of religious commitment or maybe even just on a learned sense of what I would consider excessive modesty. But however little I empathize with the particular motives, the idea of forcing a woman to reveal herself when she does not want to feels like a kind of sexual assault.
As conservative commentator Andrew Coyne has pointed out, over the past years there have been just two women who felt unable to expose their faces in public an so were permitted to do so in private rather than during their actual citizenship ceremonies.
The cynical attempt by our current ruling party to make an issue of denying such women the right to citizenship without public violation of their privacy is something which will disgrace all of us if it is successful - or even if it seems to have been successful. So it must be made to fail.
The biggest factors contributing to our economy are external, and the actual differences between our parties on economic issues are minor compared to the harm that could be done to our social fabric by this kind of xenophobic bullying. So if you can't bring yourself to vote for any of the alternatives, then please just stay home on the 19th. Don't shame yourself by supporting the man who would make us a nation of small-minded bullies.
Our history proves why racial and religious division is dangerous.

From Charles Kenny of the 'Center for Global Development', writing in The Atlantic:
Those who are anti-coal, anti-gas, anti-dam, and anti-nuclear when it comes to energy development in the developing world are implying that people there shouldn’t use electricity at nearly the level or low price that Westerners do. This, in turn, denies people safety, security, longevity, and comfort.

From Alex Frankl in The Guardian (referring to Tony Abbot's anti-environmental success in Australia)
"After years running focus groups I’ve learned one thing: technical terms like ‘carbon’ and ‘emissions’ can never win against a simple story about tax"
except here in BC where Tieleman invented this regressive "populist" message and managed to turn it into a (well-deserved) loser for the NDP.

So begins Matthew Beard's response to Stephen Pinker's recent article about the effect of intrusions by "bioethicists" into decisions about medical research and practice (which all came to my attention via Russell Blackford's response to the response).

Almost every morning I wake up with thoughts running through my head. Often the internal monologue drifts into the formulation of something like an essay but it rarely gets written down.
In fact the exit from bed is often prompted my more immediate physiological needs and the resolution of major political and philosophical issues is deferred in favour of matters of less global significance such as whether or not to go to the gym before breakfast.
One of the reasons I started "blogging" was to try and capture these imagined gems (and others which come to me at other inopportune times like when driving or riding my bike). But in practice my blogging has been more in the reactive mode which originally led to the term "weblog" as a log of web activity to refer to a record of annotated links to web resources. Time for a change perhaps.

In his post on Hyperbolic and exponential discounting, Murray Bourne objects to the comment by 'kissmetrics' in Six Advantages of Hyperbolic Discounting that "the phrase hyperbolic discounting is despicable jargon".
But actually I tend to agree with that judgement - though not to the credit of the 'kissmetrics' author. ...more »

France has log been a leader in finding and using alternatives to Carbon combustion, and also in legislating against potentially dangerous extraction schemes such as fracking. And now that solar technology has become cheap enough to make sense in many contexts, France appears ready to back it with legislation rather than bribes.
But in the article France Says New Roofs Must Be Covered In Plants Or Solar Panels (at ThinkProgress), ends with a weaselly remark that "France has lagged behind other major European countries like Germany, Italy and Spain in solar power development. As of last summer, France had just over five gigawatts of photovoltaic capacity, accounting for around one percent of total energy consumption. Germany has nearly 40 GWs installed. France is heavily reliable(sic) on nuclear power for its energy, and nuclear generation in 2012 made up about 83 percent of the country’s total generation." So Germany's solar effort, being about 8 times that of France, displaces about 8% of its Carbon combustion - which France has beaten by a factor of ten by going nuclear. Some laggard!

Finland, Home of the $103,000 Speeding Ticket — The Atlantic.The clearest case for this is in cases where there is a fine or jail time option. Why should the poor suffer loss of a much greater fraction of their entire lives than the rich for the same offence? But total assets should figure in as well as current income, and the same principle should apply to corporate wrongdoing - with the penalty being conversion to the state of a fraction of total equity (including voting rights) comparable to whatever the jail term for the same crime would be for a guilty individual as a fraction of an average expected lifetime.

Massimo Pigliucci has a new blog about his experience of following a "stoic" philosophy.
My goal in following Massimo is not to become a Stoic but just to get a better understanding of what it means, and in particular how the attribution to Stoics of faith in the Logos squares with the often expressed idea that they didn’t hold to an objective moral law.
As one who strives to live "according to positive values” but “reject the idea of an objective, universal and unchanging moral law”, I don’t see any contradiction there. But given how often people claim to see one, I will be interested in leaning more about how the classical responses to that perception compare to my own. ...more »

Sean Carroll identifies some Wrong Objections to the Many-Worlds Interpretation of Quantum Mechanics, which is fine but I'd rather he addressed some of the better ones.
I have always thought of (my own experience of) the universe as corresponding to (a very small part of) one particular configuration of a stochastic system, and that having a theoretical model for that system allows me to predict conditional probabilities of certain features (measurements) given others (state preparations). I suppose other configurations could be regarded as alternate worlds which *could* in some sense exist. But why is it necessary (and in fact, what would it mean) to suggest that they *do* exist?
Oh dear! Now I feel a little Feynmanesque "poem" coming on:
We don't know the meaning of "meaning",
And we don't know the meaning of "is".
So how can we possibly claim to know
What the meaning of "the meaning of "is"" is?

Shadi Hamid and William McCants (of the Brookings Institution) object that "John Kerry Won’t Call the Islamic State by its Name Anymore". The article contains two arguments, the first very bad and the second very good.
The good argument is that no non-Muslim has any business dictating what is or is not "true Islam". It may be fine to report on one's understanding of what the majority of Muslims seem to be saying on the matter, but to put that in the form of an authoritative declaration is both patronizing and ridiculous.
But the idea that this forces one to accept the self-declared "name" of an organization is also ridiculous. If the LRA had decided to call itself "Christians of Africa" would anyone seriously think it appropriate to go around saying "the Christians of Africa must be destroyed"? Of course it is appropriate to refuse ISIS the dignity of calling it "The Islamic State", and indeed to accept that designation is an insult to the many Muslims who do not accept it as such. (But of course this refusal can and should be done by reference to the requests of other Muslims rather than to one's own position on what is "true Islam".)

The proper response to Islamic Zealotry (including some criticism of Walzer's position) has also been discussed (again in 'The Atlantic') by Shadi Hamid with particular reference to the situation in France.
Hamid points out some of the real inconsistencies in the French (and much of the European) position, but his analysis also seems to me to be dangerously off-base in some respects.

Apparently the conservative pundits and right wing religious types are all excited about President Obama's having mentioned that using religion to brutalize other people is neither a Muslim invention nor foreign to the American experience.
According to ThinkProgress, Russell Moore, President of the Southern Baptist Ethics and Religious Liberty Commission, said, “The evil actions that he mentioned were clearly outside the moral parameters of Christianity itself and were met with overwhelming moral opposition from Christians.” Would that be the same Southern Baptists whose very raison d'etre was to split off from the main Baptist Church in order to allow their preachers to be slave owners (and who continued resisting integration right through the 1960's)?
See also Ta-Nehisi Coates' take on this, and also Jim Fallows, at The Atlantic.

The European has an article on the new Greek finance minister - which apparently picks up on a report in The Guardian. There is also news about his discussions with Osborne and other Euro finance ministers but in a profile of the man I would have liked to learn more about his economics background. Anyhow I guess it's nice to see even just one example of a male politician being discussed largely in terms of his appearance and clothing.

From Kenan Malik comes this discussion (to me via 3QuarksDaily) of the 'Kennewick Man' controversy (which, it seems, basically boils down to the question of whether modern indigenous tribes have a right to claim the bones of Starfleet Captain Luc Picard - who was apparently killed by someone he came upon during a time travel excursion to ancient North America).
To what extent should people's religious beliefs and claims be given sufficient credence to interfere with the reasonable activities of others (such as the excavation of a site which any plausible interpretation of the data dates to well before any ancestors of the claimants were likely to be in the area)?
Is it perhaps plausible that North American aboriginal populations of hunter gatherers of 5 to 10 thousand years ago were so much more sedentary in their habits that they occupied the same territories for periods over which almost every other region of the Earth has been occupied by multiple different populations?
Does "respecting" even the irrational and/or harmful aspects of traditional belief systems as appropriate for some racially defined populations not insult the basic humanity of the individuals in those populations by letting them be indoctrinated as children into irrational and often racist beliefs and attitudes?
Has not the urge to throw off the chains of silly oppressive dogma been both expressed and suppressed throughout history in all races and cultures, so that the torch of enlightenment has never been owned by one particular culture and the struggle to maintain and extend its reach is not a recent "clash of civilizations" but an ongoing conflict within each culture and family, and even often within each individual?

Prompted by Michael Walzer's piece on Islamism and the Left in 'Dissent Magazine' (to which I was led by Jeffrey Goldberg's report in 'The Atlantic' on French PM Manuel Valls' resistance to the term "islamophobia" ).
The Zealotry of Righteous Assholes
- is a universal phenomenon to which we are all susceptible
- is the most disproportionally visible external face of all religions
- is also highly visible in various political tendencies
- is often prompted by some kind of imperialist or classist oppression but distorts the response into an excuse for the exercise of excessive violence and other self-indulgent behaviour
The identification of everything that is fair and reasonable as "Western" values to which the rest of the world should not be "subjected" is a cruel "Occidentalist" echo of the simplistic and patronizing "Orientalist" attitude that was condemned (and arguably much too sweepingly attributed) by Edward Said. Or, as Walzer says, “individual liberty, democracy, gender equality, and religious pluralism aren’t really Western values; they are universal values.”
The article is linked to a response by Andrew March and a reply to that from Walzer. March's response strikes me as turning Walzer on his head and interpreting him as accusing the left of refusing to confront Islamism at all, when his main thrust seemed to me just to be against the all-too-frequent pseudo-PC rejection of even appropriate levels of anti-Islamism as "Islamophobic". March correctly identifies that the problem is often "a less black-and-white disagreement about political judgment in specific contexts". And he goes on to identify the "critical motive" of those who "have expressed doubts about the applicability of European conceptions of strict secularism to Muslim countries" as "the freedom, autonomy, and self-representation of the peoples in question"(note peoples not people). But when he says that "The war against violent Islamism is taking care of itself", what he really seems to mean is that it is just fine to let it be handled in the worst possible way - which will indeed turn it into a "clash of civilizations" rather than an appropriate level of support for those who resist zealotry wherever it arises.
In a way this argument is reminiscent of some at the height of the cold war when leftists struggled with their own kinds of zealotry and disagreed on how to respond to the errors and misdeeds of the "communist" world relative to those of our own people and governments.

Briggs is certainly right that much of what is touted as 'Artificial Intelligence' is just the use of electronic machinery to implement the calculations in a method devised by human intelligence. Indeed, for now that really is all that computers can do. But it already goes far beyond playing optimally at tic-tac-toe (trivial) , or chess, or simple kinds of poker. Those are what attract popular attention, but they imply far less for the future than do even the earliest attempts at voice and image recognition./p>
A true "learning" program isn't just the implementation of a previously worked out method of solution to a particular problem, but takes as its input the results of its various earlier responses to similar problems and from that constructs a better solution algorithm than the one it had before[*]. This can be done deterministically by a machine, and perhaps it is only hubris that convinces some of us that what we do is qualitatively different from that.
So I think Briggs' commenter Larry Geiger nailed it with “The extrapolation from what computers can do to what some people *think* that they can do is foolishness”(emphasis added).
[*]Update(2015-01-13) - like this which coincidentally came to my attention on the morning after I wrote the above.
