    These days, with GUI-installed Linux distributions, Linux suffers from the same problem Windows used to be derided for: services are on by default.

    Something I wrote for my website but haven't posted yet:

    Linux is much more secure than any version of Windows, both in design and in practice. There simply isn't any significant malware (viruses, spyware, adware, trojans, worms, etc.) for Linux. There have been no widespread viruses or spyware for Linux in all of its history. There are several reasons for this.

    Linux inherits from its Unix ancestors a robust, well-polished security model that has weathered a large number of attacks. One of the key elements of this model is notion of "normal" vs. "privileged" users. Windows, which has grown slowly and painfully out of DOS (a single-tasking, single-user system) has none of this history and its security suffers greatly.

    It's easiest to explain this by contrasting the schemes. Consider, say, Windows 98. Anyone using the system can do whatever they like to any part of the system including the fundamental operating system software. If you delete the wrong file, your computer is useless until you reinstall. More dangerous still, if any malicious program gets onto your machine, by any means at all (email, visiting the wrong website, downloading a program from the net), they can do anything to your computer. (And they do.)

    Windows 2000 and Windows XP are supposed to be better in this regard. The operating system can support "regular" users with limited privileges and "administrators" with more capabilities. However, Microsoft had a problem with this - most of the software developed for Windows requires more privileges than a regular user has. In practice, most software simply won't install or work properly for a regular user. So, in the real world, most people run with full administrator rights, and the situation is exactly the same as Windows 98 and its cousins.

    One of the main problems with this is that malware is no longer written primarily by adolescent pranksters. Malicious programs are now big business. Once they have taken over your computer, there are many ways to make a profit. First, they can use your computer to send spam email. They can also use your computer to host a website selling things advertised with spam. They can pop up advertisements on your screen regularly, and redirect your web surfing to sites they want you to visit. They can also use your computer as part of a Botnet, carrying out extortion against other websites. And, since they usually modify the fundamental operating system when they install themselves, they can be impossible to remove without wiping the system clean and starting over.

    Microsoft has recognized this problem and is trying to address it in Vista. The main feature intended to address this is called "UAC", or "User Account Control", where users run without full permissions, but when a program needs to do something that requires more permissions, Windows stops and asks the user if they wish to allow it. However, because of the history of Windows detailed above, almost anything you can think of - even just removing a shortcut from your desktop - requires extra privileges. So the warning popups arise constantly as you use the computer.

    Don't just take my word for it. See what a Windows fan has to say.

    In Linux, normal user accounts do not have the ability to change anything in the system willy-nilly. Even if a malicious program were to get onto the machine, it couldn't alter the OS or damage critical system files. Indeed, it would not even be able to alter the files and data of other users on the system.

    But this limitation, unlike Microsoft's attempts, is not opressive. When one needs to do some

    As I stated in my original post, Christianity traditionally has defined "free will" to mean the ability to do what is right.

    Functioning thermostats have that ability, too.

    First, "classical free will" wasn't defined as "unpredictable even in principle."

    Then help me out by maybe providing what your definition would be? Is it any of these? Apparently you're using some concept like "the decisions of a person with free will at instant 'X' are not fully determined by the state of the universe at time 'X minus epsilon'". Let's reformulate that a bit: "Even if you knew the state of the universe to infinite detail at time 'X-eps', you could not predict with 100% accuracy what Joe Freewill will do at time X."

    Now, let's propose something almost logically equivalent, but not quite: "No matter how much information about the state of the universe you gather at time 'X-eps', you could not predict with 100% accuracy what Joe Freewill will do at time X, for epsilon greater than some value."

    If epsilon is small enough, then in any concievable practice, there is no possible way to differentiate the two.

    Second, the bar for good scientific theory isn't chaos.

    The 'bar for good scientific theory' is if it makes accurate and testable predictions. Chaos theory does that. And yeah, there's plenty of research showing chaotic phenomena in the brain. Google for it.

    If something is unpredictable, we expect mathematically that it will follow decision paths with equal probability (law of averages and all that). But this is exactly the same thing as saying that there's no will involved whatsoever!

    Go read the link on chaos theory above. You really need to. Chaos is unpredictable but not random, and certainly doesn't involve all possibilities having 'equal probability'.

    You can't find a definition of free will that makes you anything but an automaton in science...

    So, yeah, you can't actually "propose any situation at all where the difference matters". How would you tell the difference between an 'automaton' that shows foresight, intelligence, and planning, but is not fully predictable... and someone with 'classical free will'?

    Science has already deflated a lot of overinflated, egotistical posturing by the human race. Our place in the Cosmos has moved very far from the 'center of the universe'. I'm not particularly troubled by the theoretical notion that everything I do is, in some sense, 'determined'. In any practical sense, it's not - there's no way to make any use of that insight. In what way would my life be improved by the addition of "classical free will"?

    And it might bother you the most that when Christianity talks about the will, it's logically more consistent...

    If a god builds a universe, it can build in a particular moral code if it so chooses, or even a plethora of moral codes, each applying to different entities in different situations.

    If you assume that moral codes are simply prescriptive mandates handed down from on high, then I suppose so. How, exactly, would the 'moralness' of such a 'moral code' be mediated? Could a God create a universe precisely like this one in all observable aspects, with the sole difference being that taking care of human infants was, in fact, evil, and the highest moral good was torturing babies to death instead? What is the specific feature that invests one rule or the other with 'moralness'?

    There are alternative, and to my mind far more defensible, ways of developing a 'moral code'.

    This is not what Socrates showed at all.

    Au contraire, what he pointed out is that there's really only two choices to pick from. Either something is 'good' purely because (the) God(s) will it so, or else some things just are good, and God perfectly recognizes those things that are good. My choice of language about Nazis was not 'biased', it pointed out the logical conclusion of picking the former. In that case, there really is no difference between "Speed Limit 55" and "Thou Shalt Not Kill"; it's just that the latter is backed up by the Biggest Beat Cop Around. It really is just the ultimate case of "Might Makes Right", as my 'torturing babies' case makes above.

    The latter choice is, as I point out above, far more defensible. A 'God' could design a universe with various features, and moral codes would arise from the desires and intents of the sentient agents within it interacting with the features of that universe. But that would mean that you could not have a universe that was "identical in all respects except that baby-torturing is good", because the fact that torturing babies is evil is logically compulsory given what humans are and what kind of universe they live in.

    It hasn't anything to do with prediction. Science by its nature doesn't allow free will, unless you want to invest rocks with as much free will as you have. So your assumption is grounded on an attribute you've invested yourself with that contradicts the facts, at least as far as you're willing to gather them. All you've really done here is to change the meaning of "free" to "(humanly) unpredictable."

    There is no practical difference between "classical free will" and "unpredictable even in principle". (Note: chaos isn't just "(humanly) unpredictable". It means "nothing in this universe can hope to gather the kind of information necessary to predict it for any useful length of time".) A rock can be predicted in an enormously wide variety of situations (though not all of them - e.g. a rock in a chaotic orbit) to a very large degree of accuracy.

    Can you explain why I should care if I only have 'an effectively perfect simulation of free will', and not the genuine article? Can you propose any situation at all where the difference matters? Come on, how can anyone differentiate between someone with "classical free will" and someone that's "unpredictable even in principle"?

    It doesn't look like all school districts have the combination of money and interest to do that. Too bad, because education is most important in areas where people have a strong need to move up the economic ladder.

    The gist of it is this -- we all seem to have some innate sense of morality that transcends culture and societies. (The idea that actions can be right and wrong is pretty much ubiquitous, regardless of whether a particular act is socially acceptable.)

    Let me show you an example of that moral sense. Take two tests for me. Here's the first one - a set of cards with letters on one side and numbers on the other. Which cards do you have to flip to determine if the following condition holds: "If there's a D on one side, then there's a 3 on the other.":

    D / F / 3 / 7

    Okay, now here's another test. You have a set of cards before you. Each card has information about patrons in a bar. On one side is what they are drinking, on another side is their ages.

    Drinking wine / Drinking soda / 25 years old / 16 years old

    Now, let's say you're the bouncer at that bar. Your job is to make sure that no one under the age of 21 is drinking alcohol. Which of the above cards do you need to flip over to see if that condition is met?

    Most people have a lot of trouble with the first test, but find the second test pretty easy. The answer's the same in both cases - the first and the last card. Note that the logical structure is exactly equivalent in both versions. A lot of research has been done on this stuff, and it seems pretty well demonstrated at this point that the reason why the second test is so easy is because it asks people to detect if a social contract is being violated - in other words, it asks people to spot cheating. And people seem to have "hardware accelerated modules" in their brains for doing just that.

    Now, can you imagine why social animals, that live in groups, might do well to have such talents? Note that analogous skills have been observed in other relatively intelligent social animals like chimps and dolphins.

    So, considering that humans have been around for roughly 100,000 years (and near-human ancestors for a few million years before that), living in pretty much the same environment (physical and social) and facing pretty much the same challenges (physical and social) for all that time... do you think it likely that a 'general moral sense' might develop via evolution?

    So, yeah, I don't find that 'shared morality' argument to be terribly convincing for theism.

    ...then logically you have no reason to comply with society's proscribed values other than avoiding retribution for your anti-social actions.
