I think "natural" can work as a hypothesis for making things better, but it's just a hypothesis, not a source of reliable truth.
And I still can't see how [Matthew 21:18-21] is metaphorical unless you just take it that way. But I may as well open a history book and read "Napoleon crossed the Alps" and read that as a metaphor that even the best of us have to travel. --Hariant

Reading through, I see [edit: she - I apologize] later writes:
...a sentiment reminiscent of Orwell's thoughts.
I agree-- I've only skimmed the first few chapters but so far I find it quite clear-minded amongst very murky subject matter. There are some hilarious quotes in the first chapter. I don't know enough about postmodernism to know whether she's really addressing their core arguments.
I wouldn't defend postmodernism but the treatment of modern philosophy, particularly Humean phenomenalism, is pretty bogus. Just putting the two in the same camp is a mistake as far as I'm concerned. I've only skimmed the book (and of course I can't see parts of it) but it looks like she is systematically misunderstanding skeptical arguments (to the point where I really do doubt she has read Descartes closely) and then falling back on G.E. Moore type Here is a hand! idiocy. I do wish I could see her treatment of the burden of proof issue, though, since so much of her discussion relies on it. Part of the problem is that she is conflating around two dozen distinct positions. No real person would ever defend every single one of the positions this "Professor" defends! And every time the Professor just gives in after the Student refuses to accept one or more obvious premises. It's actually pretty frustrating to read. I probably don't accept more than a handful of the positions attributed to the professor though, so it's hard for me to tell if this is the case with all the arguments.
Jack, this is actually part of an ongoing debate with a friend and I would quite like to be better informed about what the various postmodern positions actually are. Can you recommend a good overview/starting point given that I don't have a very great amount of time to invest? Or is it simply too broad a subject to ever get a reasonable birds-eye view?
Everyone feels this way, including postmodernists.
Maybe. Can you give me a better idea of A) what the debate is about exactly and B) what your background is with philosophy?
Fair point :)
I've little formal philosophical training other than a little logic and what I've picked up out of my own personal interest.
The debate is about whether the general public's surprise when scientific consensus turns out to be wrong is explained by a misconception of realism. My counter-claim is that science attempts to approximate, and hopefully gets closer over time to, truth, and that no one should be overly surprised when a scientific theory is overturned in light of new evidence.
Readings for the topic. You can probably get by reading Wikipedia Entries and Stanford Encyclopedia of Philosophy Entries, for the purposes of your debate. Start with the Hacking, then the SEP articles then Kuhn, then Feyerbend and any other interesting names that come up.
Thomas Kuhn- The Structure of Scientific Revolutions (Summary)
Paul Feyerabend- Against Method (SEP Entry)
Ian Hacking- The Social Construction of What?
Some highly relevant SEP articles:
Social constuction
The Social Dimensions of Scientific Knowledge
Social epistemology
I wouldn't call any of the above postmodernist. Hacking just discusses "The Science Wars" from sort of a pox on both their houses perspective. Postmodernists are on the extreme social constructionist end of the debate but the best arguments don't come from there. Kuhn is classic and must read.
For general philosophy:
Descarte's Meditations on First Philosophy. Read, Meditations 1, 2 and 6. Read the middle ones only if you enjoy exercises in futility (you'll have to give Descartes the existence of God for #6 to make sense though).
David Hume Enquiry Concernign Human Understanding/Treatise of Human Nature Book One. Also, his critique of the Watchmaker argument if you haven't already heard it from Dawkins.
Kant and Hegel say some smart important things but basically not enough to justify their length and obscurity. If you can find good second hand summaries and descriptions of their views, do that. Hegel does seem to be really crucial for postmodernism.
Thom missed a couple of postmodernist forerunners. Between, Marx and the pomos, there whole Frankfurt school of Critical Theory, Adorno and Horkheimer are still canon I think, especially Dialectic of Enlightenment. And more recently Habermas (who is not close to being a postmodernist and actually is worthwhile if you're interested in political philosophy).
Postmodernists also take a lot from Freud and especially Lacan, for whom there are decent introduction out there. And then there is Derrida who really is a huge sack of bullshit. You could probably just wikipedia him and get the same out of it.
Contemporary analytic: Armstrong, McTaggart, Putnam, Quine, Frankfurt, Rawls, Nozick, Lewis, Parfit, a bunch more that will come to mind ten minutes after I publish this comment.
Postmodernism's intellectual founding fathers: Hegel, the least comprehensible philosophy of the modern world, Freud, whose theories either make no predictions of have been falsified with few exceptions and Derrida who basically just did silly things with words.
The question of how and why the general public reacts seem to be a question of psychology or sociology, not philosophy. So why are you asking about postmodern philosophical positions? worse, why are you discussing how people should react?
Completely agree.
Well my friend seems to think that it all comes down to a misplaced belief in objective reality. I disagree, but it's hard to counter-argue when I don't know what the philosophical positions she refers to actually are.
If you don't have much experience with philosophy, I would not recommend starting with anything postmodernist, or anything along those lines. Before bothering to try to understand what those folks are up to (not much, in my opinion) you might as well look at more worthwhile stuff, like:
Logic. Learn sentential (propositional), predicate, and modal logic. Learn how the recursion theorem guarantees a function to exist which maps freely-generated syntax to semantics.
Ancient. Read some (Socrates) Plato / Aristotle. "The trial and death of Socrates" plus the Republic is a good package of Plato, and Nicomachean Ethics is enough Aristotle.
American. Read everything by Emerson, and some Peirce and James. Also Wittgenstein - he counts.
Contemporary. Dennett is always a good read. Also probably some other stuff.
Existentialists. I'm not quite sure what they're doing, but it's weirdly thought-provoking. Read whatever Nietzsche you'd like (other than Will to Power), some Sartre, and whatever else falls off the shelf. Now you're getting dangerously close to postmodernism, so expect a lot of it to not make any sense.
Utter nonsense. If you're serious about taking postmodernism seriously, you need to read a lot of their forerunners. Hegel, Marx, and Heidegger are particularly bad examples. You can skip Marx, since practically everything he said about economics was wrong, and everything he said about anything else was already said better by Hegel.
Postmodernism. Feel free to complete the descent into madness by reading actual postmodernism, or just read whatever shows up here. Also consider looking in the dark places of the world, invoking the True Name of one of the elder gods, and ripping the skin off your flesh with your fingernails while blood eyeballs leak from the ceiling ichor Nyogtha permeates my face
Thank you very much for this Tom.
Why do you single out the Will to Power among Nietzsche's works?
Yes, what Jack said exactly.
The Will to Power is a posthumous publication of some of Nietzsche's notes ordered, selected and occasionally revised by his nationalistic and anti-semitic sister. It's widely thought to be not at all representative of anything he believed.
It's funny. I think this list is probably both overkill and underkill. No Hume?!?!?!
Nothing ever said by someone other than Hegel was better said by Hegel.
Also, Heidegger was an existentialist and Sartre just took his stuff and watered it down.
I'm pretty sure Heidegger asserted that he was not an existentialist (and that he was an existentialist), and he specifically said that Sartre got him entirely wrong. Though when I actually go back to find such claims, I find very few places where Heidegger actually seems to be expressing a proposition. But then, I read English translations - we all know German philosophers make more sense in the original French. And Sartre said some things that had nothing to do with Heidegger.
I agree with the sentiment, but a study of some Hegelians should demonstrate otherwise.
What in Hume is valuable? If you want to read interesting stuff about causality, read Judea Pearl. I didn't think a section on political philosophy led down the right road (for humor), and I'd recommend Locke and Mill before Hume. For empiricism, the Pragmatists really should do well enough. And surely you wouldn't want people reading Hume directly in order to understand economics? What else is there?
I have to concede - 87% of my knowledge of postmodernism consists of reading Edward Slingerland's What Science Offers the Humanities, which is yet another refutation.

"If it works for you, it works because of you." -- Mark Greenway on marriage
...it would be a mistake to suppose that the difficulty of the case [for gender equality] must lie in the insufficiency or obscurity of the grounds of reason on which my convictions rests. The difficulty is that which exists in all cases in which there is a mass of feeling to be contended against. So long as opinion is strongly rooted in the feelings, it gains rather than loses in stability by having a preponderating weight of argument against it. For if it were accepted as a result of argument, the refutation of the argument might shake the solidity of the conviction; but when it rests solely on feeling, worse it fares in argumentative contest, the more persuaded adherents are that their feeling must have some deeper ground, which the arguments do not reach; and while the feeling remains, it is always throwing up fresh intrenchments of argument to repair any breach made in the old. And there are so many causes tending to make the feelings connected with this subject the most intense and most deeply-rooted of those which gather round and protect old institutions and custom, that we need not wonder to find them as yet less undermined and loosened than any of the rest by the progress the great modern spiritual and social transition; nor suppose that the barbarisms to which men cling longest must be less barbarisms than those which they earlier shake off.

Does pure recreational enjoyment count?
After I answered your comment I still had to think about it and I had to add the following. Often it's hard to separate serious reading from enjoyment: for example you could be reading reddit or hackernews either knowing that you are just doing it for entertainment or rationalizing it by thinking you are doing serious reading not realizing that the real reason is the dopamine rush you get. How much time are you willing to spend on random internet reading and other time wasters? You have to judge it yourself. But if you are investing a large amount of your time into that maybe it's good to start reevaluating your information diet.
I agree with you (and Tim). I could benefit from reducing my information diet and giving my brain it's dopamine in a different manner.
Timothy Ferriss himself reads one hour of fiction every day prior to sleeping so I guess he was only referring to information you consume for non recreational purposes.

Three ways to increase your intelligence
Continually expand the scope, source, intensity of the information you receive. Constantly revise your reality maps, and seek new metaphors about the future to understand what's happening now. Develop external networks for increasing intelligence. In particular, spend all your time with people as smart or smarter than you.
I'll give an upvote to whoever knows the source of that.

"He who refuses to do arithmetic is doomed to talk nonsense."
-John McCarthy, on mainstream environmentalism.
As someone who regularly gets into arguments about this, I can say that he's definitely right; you wouldn't believe the amount of nonsense that can be disposed of simply by looking up the relevant numbers and doing a minute's worth of easy arithmetic.
For example, I've heard some people recently claiming that a combination of solar photovoltaics, electrolysis to produce hydrogen, and these new Bloom box fuel cells are cheaper than nuclear fission. Look up the costs of solar farms; about $3 per peak watt. Their average power output is less; we can very optimistically assume that they run at 20% of capacity on average. Efficiency losses from electrolysis and fuel cells are about 50%. Putting it all together, this would cost about $30 per watt of average power delivered. Not including the cost of the fuel cells.
A little googling will show that the total cost of building two new AP1000 reactors in Georgia is about $14 billion, and they average at least 93% of their peak power, and transmission line losses bring their average power delivered to about 1000 MW each. So their cost is about $7 per watt of average power delivered, or about 23% the cost of solar.
There's a lot of extremely harmful bullshit out there, and defeating most of it doesn't take any advanced techniques; it just takes a willingness to look up some relevant numbers and do a bit of arithmetic.
You can't run cars with power that comes directly through the power line.
You ignore the running cost of the nuclear reactors. You don't price risk from blowups and you don't price long term storage costs. Risk from peak uranium http://www.technologyreview.com/blog/arxiv/24414 is also unpriced.
If the word "average" would be meaningful in this context than you would simply compare solar cell productivity + transmission line losses to nuclear plant costs + transmission line losses.
Of course you can do simply arithmetic but that doesn't mean that you are right when it's not clear that you are using the right numbers.
No, but you can power people's homes, businesses, and industry. Currently we're burning ungodly huge amounts of coal to do that. Just because a green energy source isn't the final solution to all energy needs is not a point against it.
I was addressing the argument, often put forward, that the up-front costs of nukes are much higher per-kilowatt than other green energy sources. The operations and maintenance costs of nuclear energy are so low that they are seldom attacked. Here are some approximate numbers
Those are both included in the O&M costs, actually. And by the way, name me a single light water reactor that has blown up. Or any modern reactor, for that matter. There are good reasons to believe that such an event is very unlikely or (in some cases) actually impossible.
As for long-term waste management, I've addressed that in more detail here. It's surprisingly straightforward.
Construction costs? O&M costs? O&M plus loan payments until the up-front investment has been amortized off? There's more than one type of cost to consider, so I decided to focus on the particular argument that construction costs were too high.
As for "average" being meaningless, it's true that I've ignored transmission line losses. Those are not high enough to significantly affect the calculation, and both nuclear and solar tend to have longer-than-average distances between the plants and the consumers, so I doubt there would be too much difference between them (unless you went with something like the idea of putting solar farms in the Sahara desert and sending the electricity to Europe).
You aren't comparing the price of nuclear vs. the price of solar but the price of nuclear vs. solar + hydrogen.
By your own numbers the price of solar is 3$ per watt while the price of nuclear is 7$ per watt.
Your solar power plant that's backuped with hydrogen produces the energy at different prices at different times. While a nuclear plant can produce the same amount of power at night than at day it's not possible to change the amount that gets produced as fast as you can change how much hydrogen you burn in fuel cells.
Oh crap, you're right. I got this confused with another discussion. Sorry about that. Anyway, the latter is a more meaningful thing to compare.
That's cost per peak watt; a more relevant number is cost per average watt (assuming perfect energy storage at no cost). To get that, you have to multiply by the capacity factor. For new nuke plants, that's about 93%. For solar, it about maxes out at 20%. So construction cost per average watt would be about $7.50 for nuclear and $6 for solar.
Of course there's more to it. There's the cost of storage and backup, and maintenance, and of course the plant lifetimes differ by a factor of 3-4, and both types of power will get significantly cheaper to build over the next decade or so. But as a first approximation, you could do worse than multiplying peak cost by capacity factor.
Correct (for large light water reactors). Power grids do need the ability to adjust production to meet rapid changes in demand. What of it?
The motto of this book on sustainable energy is Every BIG helps
up-voted, but I don't think it's simple arithmetic that they're missing, there's a lot of ideological baggage preventing the masses from seeing nuclear as the better alternative.
I'd caution against such under estimation of people's mental capacities, if only they knew how to add and subtract almost entirely misses the point-and is too condescending, not good PR.
politics is the mind killer seems to be relevant here.
I never said that they're incapable of doing the math, just that they don't. For whatever reason. No further condescension is intended; just a really helpful suggestion.
ok, I see your point.
You can make the calculation return any result you want, for example by including cost of millennia of nuclear waste storage in price of nuclear power; another thing - nuclear power gets massive federal insurance subsidies (but then coal gets free license to kill people by pollution etc., so it's not exclusively nuclear problem).
If you know what result you want, you will be able to come up with it.
You can calculate arbitrarily high costs for anything if you try hard enough. What of it? We're not going to deal with nuclear waste by sticking it in Yucca Mountain and guarding it for thousands of years; that would be silly. Here's a summary of how to realistically deal with nuclear waste. We have more than enough money for this budgeted as part of every nuclear plant's operating and maintenance fees.
Not true (PDF warning). The nuclear industry runs its own insurance pool, paid for out of their own pocket. The regulations requiring this do say that the federal government may help out in extreme circumstances (i.e. something on the scale of Chernobyl) but to date the feds haven't spent a dime on this. And I see no reason to believe that they ever will.
If you're motivated to play games with the figures, consciously or not, then sure you can. But I try to avoid that sort of thing, and it tends to be pretty obvious.
Note that I'm not accusing you of dishonesty -- but I'm guessing that you ultimately got those arguments from someone who was trying to make the numbers fit his position, rather than the other way around.
Another thing to calculate on the cost of nuclear power:
photovoltaics don't have evacuation plans, labled evacuation routes, large government monitoring safety boards, or National Guard/Air Force aerial defense concerns.
It's hard to look up data on so-called "externalities" like that.
Solar power requires heavy industry to build, and that has loads of externalities. It takes up a lot of space and affects local climate and ecology. And then there's the unreliability of the sun, which can have economic consequences.
As for the nuclear externalities you mentioned, the evacuation planning and government safety things are paid for by power plant fees, and budgeted into the cost of building and operating the plants. Defending the plants is something you have to do with all forms of power generation, and I actually think you're miscalculating the risks by looking at the power plants themselves, which (in the case of nuclear) tend to be pretty beefy and well-guarded. Attacking the transmission lines would be much easier, and much harder to defend against. This goes double for wind and solar farms that are located far away from everything and have to use longer power lines.
(And really, what are the odds you'll ever have to use those evacuation plans? I'd worry more about crossing the street. No water-moderated reactor has ever had an accident that made evacuating people nearby a good idea, even after all these decades of operating them, and there are good theoretical and practical reasons to believe that it never will.)
And while we're looking at externalities, consider this: nuclear is the only option that's currently competitive with coal on a cost-per-kWh basis. Very cautious safety regulations, by holding nuclear power back, are responsible for a lot of coal emissions -- which are far more dangerous than anything people are talking about for nuclear plants. Paradoxically, our worries about nuclear safety have made us much less safe. What we have here is a widespread failure to shut up and multiply.
I really like this as a test-case for rationality, because it's important and we really can look at it probabilistically for insight.
As a point withiin the greater whole, I don't think that the security requirements of photovoltaics are the same as those for a nuclear reactor. Also, security difference between "spent" photovoltaic cells v. spent nuclear fuels?
In any case, the overarching point: "you wouldn't believe the amount of nonsense that can be disposed of simply by looking up the relevant numbers and doing a minute's worth of easy arithmetic." turns out to not be so simple, because there are a lot of issues involved. There's the issue of disposal, which you show a link to, but you don't seem to have incorporated those numbers. There's the issue of how much taxpayer money goes into scrambling jets near Indian Point each time alerts are raised, etc.
The calculation clearly isn't easy in the present, and also does not incorporate the cost/benefits analysis of focusing on photvoltaics because ultimately they will almost certainly be more efficient (your efficiency/production rates for existing infrastructure doesn't reflect changes and advances in technology, of which there are many).
In short, "easy arithmetic" isn't always so easy.
I won't bother looking up figures as I'm not terribly interested in long term nuclear waste, but you're wrong about insurance (at least your argument is wrong, not necessarily the conclusion).
Implicit or explicit guarantee for extreme cases are worth trillions. There were some papers measuring how much even implicit guarantee was worth for Fannie Mae/Freddie Mae, and this was enormous amounts by letting them raise money far cheaper than would be otherwise possible (and taxpayers eventually paid, but it was beneficial to Fannie/Freddie long before that).
Do you consider the law regarding car liability insurance to be a subsidy? It requires you to carry liability insurance up to a finite amount, despite the fact that you can do much more damage than that with your car, and then bankruptcy law will shield you from paying the full amount.
This is the same kind of insurance nuclear plants have: they're require to have an insurance on up to $X of damages, and then "someone else" bears any cost beyond this.
Nuclear plants can't be insured for the damages in a meltdown. Not because the risk is so huge that it should never be done, but because any jury award would be effectively infinite, irrespective of the actual damage. There's no point to buying insurance when the uncovered liability increases in lockstep with your insurance coverage. However, the actual meltdown risk is extremely small and even the required insurance is effectively overinsuring the plants.
This nuclear plant "insurance" can't be compared to what FM/FM had because they are able to continue operation and making profits after a "meltdown", while a nuclear plant would be over and done with.
If you don't like the kind of uncovered liability nuclear plants have, they're the least of your concerns -- you really should be advocating an end to driving, since no driver can meet the insurance standard you seem to expect out of nuclear plants.
Now, with that said, you are correct that comparisons of green technologies to coal do conveniently leave off the damage that coal plants spill off onto other people and are therefore misleading. I've long railed against assessments of coal that ignore the cost of dumping toxic crap into people's lungs. Example. (ETA: Better example.) Still, that requires an objective accounting of environmental costs, not just (as is often the case) assuming they're infinite.
Making drivers not responsible for damages they cause is a massive subsidy, and without it we'd have far more investment in car safety (and I mean genuine kind like replacing human drivers with robots, black boxes, and compulsory alcohol testers before it lets you drive, not current air bag waste of time), and far fewer deaths and injuries.
Pardon, but I don't see how this is responsive to my comment.
1) Drivers are made responsible for the damages they cause, up to the limits imposed by bankruptcy law; the law also attempts to ensure [sic] that each driver on the road is capable of paying up to $X in damages. What they are not made responsible for is arbitrarily large damage they could potentially do, but this is unavoidable -- no one is capable of setting aside that much money, even solar power operators (or rich people).
2) In absence of "making drivers not responsible for damages they cause", we most certainly would not have more investment in car safety; we wouldn't have cars, period. (BrE: Full stop.) Or, without the multiple negatives: If everyone driving had to be capable paying all damages they could ever potentially do with their vehicle, no one would be allowed to drive, or use most technologies. I don't think you're understanding the implications of this requirement.
Yes, drivers -- and nuke plants -- should carry insurance. Maybe the required amount (in either case) is too high. Or too low. Or derived from the wrong process. But no one can insure unlimited liability, so the safety improvements you describe just wouldn't happen if that were a requirement; the technology just wouldn't be used. But once you accept that people should only have to insure up to a finite amount, and given the low, self-borne risk of nuclear plants, you must accept that they already meet this.
3) Arguably, the reason we don't already have self-driven cars is precisely the phenomenon I warned about: uncovered liability increasing in lockstep with coverage. The average person who kills someone with their vehicle is typically required to pay a lot less than when it is done by a wealthy corporation. Given jury reactions to new technologies and wealthy corporations, if someone actually did offer self-driving cars, they could very well have to pay out more in damages, even if they were safer than 99% of human drivers!
Not to dispute your point, but solar photovoltaics should hopefully soon become much cheaper:
http://media.caltech.edu/press_releases/13325
Very cool, although it needs to become a lot cheaper if it's going to be competitive. I see a viable niche for solar in places like California, where the air conditioning needs in the summer cause the peak power to come at a time when the sun is shining brightest. This is rough on the power grid. Solar panels could be very useful for smoothing out the peaks there, if it can be made cheap enough.
Meanwhile, nuclear has a new wave of modular reactors coming. It's going to get quite a bit cheaper, too, and it's still nowhere near its full potential, as the LFTR folks can attest.
Anyway, nerding out aside, my point remains that simple arithmetic is necessary and often sufficient to discuss this sort of thing like grown-ups.
Emotions are the lubricants of reason. —Nicholas Nassim Taleb
A touchstone to determine the actual worth of an "intellectual" — find out how he feels about astrology. —Robert Heinlein
While I understand, judging people's intelligence by comparing their beliefs to yours should be done with care.
Worth as an intellectual is completely different to 'intelligence' but your point stands even then.
It would be more interesting to hear how someone justifies believing in astrology. Typically it's a long string of horrifying nonsense that tells you quite a bit more about a person than just asking "Do you believe in astrology? [Y/N]"
I'm atheistically agnostic about astrology..."I doubt it, but who am I to say?". As in intellectual exercise once I tried to come up with a plausible mechanism for how astrology might happen.
Who's to say that planetary alignment could not in fact subtly effect protein expression or the development of neuroligcal systems during very critical stages of cell division and development in the embryo? To be clear, I don't really buy it, but with a little imagination.....
By the way: Welcome to LessWrong! Feel free to post an introduction of yourself! If you want to get a good head-start on the kind of thing we do here, "What Do We Mean By Rationality?" is a good start, and if you're ever looking for other material, you can browse the sequences and the top-rated posts to find a lot of good essays.
On this specific issue, ata has the most relevant link, but I would add a couple other points:
Just because you could, in theory, be convinced of astrology at some point doesn't mean you have to be agnostic now - you can be quite strongly convinced of its incorrectness and still accept correction should some ever come to your attention.
If you are actually quite skeptical of astrology - if you believe it to be strongly contradicted by the evidence - this is one of the places where we would hope you would say so. Humility is a virtue when it makes you careful, not when it is attire you wear to affirm your open-mindedness.
Please keep posting, by the way - your remark on the externalities of nuclear power was a good one, and I would like to hear your thoughts on other occasions.
Being that there is a total absence of evidence that astrology can consistently predict anything better than chance, why is it even worth talking about possible mechanisms? Until there's any positive evidence for it, the right answer to "How does astrology work?" is "It doesn't."
"I doubt it, but who am I to say?" is still being too generous to it. It is an arbitrarily privileged hypothesis.
Edit: Be careful with those "intellectual exercises", by the way. You're not going to become a stronger rationalist by practicing rationalization: "Your strength as a rationalist is your ability to be more confused by fiction than by reality. If you are equally good at explaining any outcome, you have zero knowledge."
Point taken about evidence of predictive value v. random chance. Just to clarify, the intellectual exercise was more in the lines of, rather than taking an astrology book and seeing if what it says is predictive v. chance, let's rephrase the question: The question not as "is Astrology real or correct", it becomes "could time of birth affect development, apart from seasonal effects?". (why day or hour of birth, from year to year, might matter). Then the exercise leads to "could planetary alignment (gravitational changes, electrical fields, etc.) have subtle and predictive effects on personality or development?" And that is where I hit "who am I to say" seeing as that's not my area of knowledge, and I have not come across any studies that might have analyzed that either way. Maybe it's because some proto-analysis suggests that it's not "worth" studying because there's nothing to study (fields from high-tension power lines affecting development, possibly), but maybe the "worth" is more monetary: who's going to bother funding it? a. it seems ridiculous, b. it would be really really hard = expensive, c. the effect might be there but too subtle for us to measure at this time. Anyway, I'm in no way a proponent of astrology, just relaying a process that seemed a rational exploration at the time.
"The question not as "is Astrology real or correct", it becomes "could time of birth affect development, apart from seasonal effects?"
I have wondered that too. Trouble is: signal-to-noise ratio. Maybe you were born in December and it was cold, so you have a slight tendency to think of the world as hostile (say).
But that will be drowned out by a zillion other far-more-important influences.
Same a fortiori with gravitational/electromagnetic fields. Start with gravity. I calculate on the back of the envelope the pull of Proxima Centauri (the nearest star that's not the sun) as being on the order of 7 piconewton, or 7 trillionths of a newton. (A newton is enough force to lift a hamburger.) So what if you are pulled in the direction of P. Centauri by an amount as feeble as that? That's about as much gravitational pull as an orange has on you 50 metres away. :) Not to mention all the other stars are acting in opposite directions. Result: nil.
Electrical force argument left as an exercise for the reader.

Scrapheap Transhumanism:
"I’m sort of inured to pain by this point. Anesthetic is illegal for people like me, so we learn to live without it; I’ve made scalpel incisions in my hands, pushed five-millimeter diameter needles through my skin, and once used a vegetable knife to carve a cavity into the tip of my index finger. I’m an idiot, but I’m an idiot working in the name of progress: I’m Lepht Anonym, scrapheap transhumanist. I work with what I can get."

Interesting article, but that guy could have avoided some suffering if he knew about ways to lessen pain without anesthetic. A common technique used by body piercers is to numb the area with ice beforehand.
Really though, most of the benefits of those things don't require any cutting. Why not wear the RFID tag in a bracelet? Why not temporarily glue rare earth magnets to his fingertips? If that guy ever needs an MRI, he'll have to get the magnets removed from his body. If he's in an accident and the doctors don't know about his magnets, the MRI could injure him or damage the scanner.
Edit: Oh, he has a blog. It's umm... interesting.
Just a note: Lepht is genderless. It identifies as gender neutral.
Fringe people are associated with defects both mental and physical; like many stereotypes, there's some truth to it.
Why is anesthetic illegal for "people like him"?
I think he meant people doing self-surgery on their own. Ie. you can't go to a pharmacy and buy lidocaine just because you want to implant an RFID chip in your hand. As for why, well, that's perhaps another point.
Due to not being an appropriately-credentialed expert, I expect. The article does mention that he got a very negative reaction from a doctor.

"There is an expiry date on blaming your parents for steering you in the wrong direction; the moment you are old enough to take the wheel, responsibility lies with you."
-- J.K. Rowling, Harvard commencement address.
This is potentially misleading. If you want to improve your life, discovering who you should really blame does not amount to accomplishing an instrumental goal.
I don't see how this relates to the quote, unless you're interpreting "responsibility lies with you" as meaning "you've only yourself to blame". To which I would say, well, don't do that.
Alas after a certain age, every man is responsible for his own face. -Camus
If they raped you, starved you/fed you paint chips, beat you to the point of brain injury, tortured you? How about being born in a place where the pollution is so bad that you're likely to get sick/die from with a very high probability? Places that are completely ravaged with drought or famine? Places where genocide is fairly regular? Where your parents are so destitute that they are forced to feed you the absolute worst food (or even non-"food") so that your brain/body never develops properly?
Of course, for people/places where rape/forced childbirth is prevalent or the knowledge of how pregnancy occurs is still non-existent, it's understandable. For places where the former isn't and the latter is, there really should be no statute of limitations on blame.
The quote is good, but should be understood to apply only in certain contexts (i.e., to people who weren't born into horrific conditions and who live(d) in a place with something resemble equality of opportunity.) Not understanding this perpetuates the idea that "everything that happens to you is your own fault" that appears in some popular strains of political thought today, when it clearly cannot be universally applied.
For most of the cases you describe, the antecedent isn't satisfied, so the local implication (old enough to take the wheel -> responsible) is trivially satisfied.
All advice is relative to a certain context.

Not true! The ancient Greeks measured the circumference of the Earth to within 1%.
But five hundred years ago ancient Greeks hadn't lived for centuries already.
They (Italians and other Europeans) still knew the Earth was round. Indeed, if you live near a sea port this is a very easy thing to figure out. The resistance Columbus faced was that everyone thought the world was much too big to get to the Indies in a reasonable period of time by sailing west. And of course everyone was right and Columbus had no idea what he was talking about.
Edit: And actually I'm pretty sure the authorities cerca 1492 were basing their beliefs about the size of the Earth on work done by the ancient Greeks.
note that it wasn't Europeans alone who 'knew' this by that time.
Right, I just didn't want to start listing cultures since I'm not sure who had this down and who didn't. Actually, I'd be surprised to learn of any seafaring cultures that hadn't figured this out. There is also the question of how much this information and trickled down to the non-educated person. In seems plausible some landlocked and illiterate European peasants might have believed the Earth to be flat.

Can we have a norm of using the Custom Search bar to check if a quote has already been posted?
by "have a norm of" you mean "mention explicitly in the monthly threads that this is a norm", right? As, as far as I can see, this norm pretty much seems to exist already.
Yes, I think this should be mentioned explicitly in the monthly threads.
My intentions were to decrease future occurences of duplicate posts, establish a standard of effort that should go into avoiding duplicate posts, and not hit Johannes' comment too hard because it was made before the standard was expressed and agreed upon.
Oops. I do feel a bit embarrassed for just assuming that the strip in question was recent enough not to have been posted to last month's thread. Voted in favor of the proposed norm.
I vote in favor - do you want to make a poll of it?
Edit: My vote is now registered in the poll.
Poll: vote this up if you are against the proposed norm. (And vote down the Karma Balance comment.)
Why is this voted down? Poll procedure would have this comment voted up or the other up and the karma balance down.
I find it troubling that we have to kludge a poll out of comments and upvotes.
I find it awesome that we routinely kludge whatever we need out of whatever's on hand.
No less impressive is that we occasionally notice the need.
If we begin to have a lot of polls (I admit, it's looking that way at the moment), we should request programming a new polling feature.

It's ROT13 - a Caesar cipher with a period of 13, so that encipherment and decipherment are the same operation. rot13.com has a decoder.
Ditto. On the Mohs scale of sci-fi hardness, Blindsight is aggregated diamond nanorod.
The Mohs scale is used to rank hardness of solids. It does not measure faithfulness of books to the science fiction ideal.
According to V. S. Ramachandran, schizophrenics lack the ability to understand or create metaphors.
I didn't want to link to the massive time vacuum that is TV tropes, but I figured people would understand the metaphor even if they hadn't run in to it before.
People yes. Paperclip maximizers/office assistants no.
actually it's not that easy to see the tvtropes connection, I mean I spend quite a while on tvtropes when I go there-who doesn't?- but in never crossed my mind that that was what you meant.
I understand metaphors. I just don't understand why there would be a need for scale for science fiction writing. It's much more important to be able to look up material properties.
What about a scale that tells us how much a work of fiction deals with paperclip manufacturing and resource harvesting? Surely you need some way of communicating the traditions and norms of paperclip creating to your youth.
Edit: and come to think of it wouldn't you be interested in in fictional explorations of possible future ways of manufacturing paperclips? And wouldn't you want to know which of those explorations was the least fantasy and most based on reasonable extrapolations from current knowledge?
In theory, yes. In practice, humans have very little to offer in terms of the ultra-efficient methods of paperclip production I normally use. I don't expect any book to be rated higher than 1, if you compare to what I already have.
What are you talking about? I don't have to do biological self-replication (or sexual semi-replication at the genetic level) like humans do. I just make a perfect copy of myself. It already has all my knowledge and values.
You're thinking of Mohs Scale of Mineral Hardness. AngryParsley was referring to Mohs Scale of Science Fiction Hardness, neither of which should be confused with Mohs Scale of Rock and Metal Hardness.

I just read their website.
Its embarrassing but I have to say that honestly the centripetal force argument never occurred to me before. Rough calculations seem to indicate that a large man 100Kg should be almost half a pound heavier in the day time as he is at night. Kinda cool.
Now I am dying to get something big and stable enough to see if my home scale can pick it up.
Quick look didn't find it, but I don't see why this follows (and at a wild guess, I'm guessing it doesn't). Can you link?
As you stand on the equator, with the Sun directly overhead, its gravity is pulling you away from the Earth's center. On the other side of the Earth, the Sun's gravity pulls you in towards its center. Consequently you weigh slightly less at noon than at midnight. However, since the force of the Sun's gravity on a 100-kg mass 1 AU distant is about 0.006 Newton, an average bathroom scale is not going to notice.
And the Earth is slowly curving in its orbit, generating an apparent centrifugal force that decreases your weight at midnight, and increases your weight at noon. Except for a very tiny tidal correction, these two forces exactly cancel which is why the Earth stays in orbit in the first place. This argument would only be valid if the Earth were suspended motionless on two giant poles running through the axis or something.
This was my original thought until I realized that of course it cancels or else the earth would crack into pieces.
The non-cracking of the Earth demonstrates only that the tidal force is small relative to that required to crack the Earth apart, which may not be a particularly strong upper bound on human scales. :) However, RobinZ's numbers show that it's also small relative to human weights, so there we go.
The Earth is a (fairly) rigid body held together by its internal structure, and is not required to be moving at orbital velocity at every point on its surface. That is, the effect you mention exists, but it is not clear that it exactly cancels the gravitational effect. (Or equivalently, it's not obvious that the tidal effect is small.) Don't forget that the Earth's rotation is reducing your effective orbital velocity on the day-side, and increasing it on the night-side.
Now, if you have some numbers showing that the cancellation is close to exact for the specific case of the Earth, that's fine. An argument showing that it's always going to be close to exact for planet-sized bodies in orbit around stars would also be convincing.
According to Wikipedia, solar tides are about 0.52*10^-7 g, as opposed to lunar tides of about 1.1*10^-7 g. One part in twenty million and one part in ten million, respectively.
No, because it pulls you, your scale and the Earth all (very close to) equally.
This would only be relevant if you were accelerating relative to the Earth. The scale measures the normal force keeping you at rest relative to the Earth's center; the force being exerted on the Earth does not change that. (Modulo the orbital-velocity argument, which I'll respond to separately.)
I feel like an idiot for not seeing this earlier: you're right; this is the tidal force problem.
In other words, the measured weight of 100-kg human changes from Solar gravity by 5.2 [edit: milli]grams between equitorial solar noon or midnight and equitorial dawn or dusk.
I got 0.6N (=6.7e-11 * 2e30 * 100/(1.5e11)^2). Still small, but potentially measurable. (Er, except for the whole frame-of-reference thing mentioned above.)
Oops, added a zero typing the numbers into my calculator. :oo
It doesn't. My though process was too silly to even bother explaining.
Don't forget to adjust your calculations for not being on the equator, and to take into account that 'nighttime' is not equivalent to 'the Sun pulls you directly towards the center of the Earth'. Both tend to make the effect smaller.
Even this isn't true!
I haven't yet tracked down a good quote on this type of "asymmetric intellectual warfare", where one advances some outlandish claim that lays waste to large portions of a consistent belief network, and then insists it's the victim's obligation to repair the damage. I'm pretty sure the idea has been around for a while, perhaps not in terms of that military metaphor. Is that topic covered somewhere in the Sequences?
It's clearly an abuse of the concept of the Burden of Proof. Along with some motivated skepticism.
