    It still seems to me like you are not understanding the distinction I am making, and are making other (valid) points tangential to what I'm talking about. You are working from the assumption that we have a single agreed-upon uncontroversial definition of "X", and that "the philosophy of X" just means "X"; when my point is that "philosophy of X" is often used to mean the field which asks "what is the definition of X?"

    I agree completely that whatever philosophical principles genuinely underlie the activity called science ("the philosophy of science" in the sense you seem to use it), those principles are identical with science proper, and science proper is defined as just those principles, whatever they are. I further agree that asking if and how those principles are justified is, as you say, doing something else, namely epistemology and metaphysics. But that's not what I'm talking about.

    There are many people who ask, rightly or wrongly, "what is the correct definition of science?" Many philosophical questions are really quests for proper definitions. Nobody sat down a few hundred years ago and said "We define 'science' to be such-and-such, and henceforth will proceed to derive conclusions from these definitions", thus beginning the field of science. We just have all these people who came to be called scientists who are all doing this activity which we came to call science; but what it is that all those scientists do, which distinguishes what they're doing from other things that we don't call science, seems to be a contentious question, at least amongst some people. The field of study wherein people ask these questions is what it usually called "the philosophy of science". The phrase is analogous to "the philosophy of education" or "the philosophy of art"; those phrases don't name a particular philosophy that underlies education or art, but rather a field that asks questions about philosophies which may underlie some form of education or art.

    A clearer analogue would be if you said something like "economics says that [whatever]", instead of something like "the theory of supply and demand says that [whatever]". Economics itself doesn't say anything, it's a field of study; various theories in that field say things. One is a set of questions; the other is a set of answers. Everything you're saying is true of "the philosophy of science" understood to mean the set of answers to epistemological and metaphysical questions which constitute the scientific method; my point is that it is not usually understood to mean that amongst people who commonly use that phrase, but rather they use it to mean the set of questions about "what answers to epistemological and metaphysical questions constitute the scientific method?"

    Your objection seems to overlook the point I was making.

    There is a philosophy, as in some system of philosophical propositions, underlying science; or you could say that science is an application of some set of philosophical conclusions; or that science, as an ideal methodology rather than as a sociological phenomenon (you might say "true science" as opposed to "whatever people labelled 'scientists' do"), is itself a philosophy in this sense. This is actually a contentious claim, but we both seem to agree on it so I won't harp on that.

    Then there is a branch of philosophy which asks "what are the philosophical underpinnings of science?", since it appears that many proposed answers to that question can be met with examples of things we want to call great examples of science, yet which do not adhere to the proposed philosophical characterization of science. And then, as you say, epistemology and metaphysics etc say things about the validity of those underpinnings, once we identify what they are. I personally don't think this is such a tricky philosophical problem to name what philosophical assumptions distinguish science from non-science (in other words I disagree with Feyerabend), and that epistemology and metaphysics do us just fine in investigating whether and why those assumptions are the right ones, but nevertheless there is a field devoted to the study of such things anyway.

    The only point I'm making is that while the phrase "the philosophy of science", understood literally outside any history of that phrase, could be used to mean the first of those two things ("whatever philosophical positions actually underly science"), which is how you seem to be using it, it is traditionally used to mean the latter thing ("the branch of philosophy asking questions about what underlies science") instead, and that talking about "the philosophy of science" meaning the former thing could throw off someone used to it meaning the latter. As a philosopher by training, I am accustomed to the latter sense of the phrase, and so I had to reread your post a few times before I understood that you weren't talking about a field of philosophical investigation, but rather about a set of philosophical propositions. I thought it might be helpful to point that out for future usage in case other people end up more confused than I was.

    I'd just like to comment, to all of those arguing about why science is better than non-science of some sort or another, or more particularly why philosophy is worthless compared to science: you are doing philosophy right now. Yes, even if you are arguing against philosophy, in doing so you are doing philosophy; specifically metaphilosophy, which is the philosophical investigation of philosophy itself.

    Any investigation, argument, or debate, taken far enough, has to end up in philosophy. Your fellow physicists may disagree about some details of your pet theory but agree with your underlying assumptions and methods; other physicists from very different schools (e.g. string theorists vs anyone else) might disagree with some of those underlying assumptions and methods but at least you all agree on some general, vaguely defined scientific methodology, something critical, mathematical, empirical, and realist. But if you're trying to defend such science against voodoo or whatever, you end up doing philosophy, just as much as if you wanted to defend voodoo against science.

    Philosophy is not a side in any battle: it is the battlefield.

    Previously, you said :
    the state should not punish them simply for doing something that might increase the odds of them causing harm, if no actual harm was caused.

    Recklessness is doing something that might increase the odds of causing harm, but does _not_ necessarily cause harm.

    I admit that I misstated my position there, and my parallel examples of attempted (intentional) harm and my being OK with preventing such was intended to clarify that.

    The idea is that your state of being itself should never be a crime, not should performing any action in a particular state of being in the same way as performing said action in a different state of being. Being angry should not be a crime; trying to punch someone should be, and actually punching someone should be. Likewise, bring drunk should not be a crime; flailing around wildly and dangerously should at least warrant a stop and check that this person is not doing to be a further hazard; and actually smacking somebody by drunken accident should still be a crime. Similarly, being angry should not be a crime, but trying to hit someone with you car should, and actually hitting someone definitely should; and likewise, being drunk should not be a crime, but swerving all over the road wildly and dangerously should at least warrant a stop and check that this person is not doing to be a further hazard; and actually hitting someone with your should still be a crime.

    Basically, I say if you cannot tell by a person's gross actions that they are a dangerous (whether of intentional or accidental harm), then their state of mind should be of no legal consequence. The practical upshot of that being, cops should be pulling people over for driving recklessly and then assessing whether they are safe to drive and taking them off the road if they're not, regardless of why they may be unsafe (drunk, tired, angry, whatever); but they should not be stopping people randomly and doing a chemical test just to see if you have certain blood chemical levels that would dispose a significant fraction of people to drive recklessly. The law needs to care only about your actions, and only about those actions which directly threaten (intentionally or accidentally) immediate harm to person or property.

    Yes against speeding laws unless the speed is demonstrably reckless. Just driving fast is not bad; driving recklessly is.

    Firing an AK-47 into the air in Times Square is reckless and so I would not be OK with that. By "reckless" in general I mean something like "demonstrably threatening immediate harm". If I attempt to punch someone, I think someone should be allowed to stop me before I actually land the punch; that's malicious intent though, so lets look at something slightly more analogous. If I am running around blindfolded swinging my fists wildly and people are having to dodge out of the way to avoid getting hit, then likewise I should be stopped before I actually hit anybody. That is recklessness. Likewise firing a gun wantonly in a crowded place is the reckless analogue of trying to shoot somebody. And swerving all over the road is the reckless analogue of trying to run someone down with your car.

    But just "moving around while blindfolded" should not be illegal, if somehow you are managing to do so safely; nor should "firing a gun without a target", if you are somehow far enough from other people that no one is threatened by that; nor should "driving while drunk", if somehow you can do so and maintain control of your vehicle. In all three cases, doing one thing is probably a bad idea because it is very unlikely that you can do that without recklessly endangering other people. But the recklessly endangering part is the bad part that should be punished, and if somehow you can manage to do whatever without recklessly endangering anyone, then that whatever should not in itself be punishable.

    I'd say you should be able to drive whatever vehicle does not damage public resources (e.g. roads, air) in its operation, anywhere on public property, in any safe manner, without any kind of licensing, yes.

    This is a recurring problem in many areas of law: we need to punish the actual harmful acts, rather than just things with high correlation to such harms. For this example, I agree that driving drunk is stupid and a bad idea because your reaction time and coordination is probably not good enough to safely operate a vehicle. But the only actual problem is you unsafely operating a vehicle. That should be the punishable crime, and the cause for you unsafely operating the vehicle should be irrelevant (except as testimony to your mens rea; if you're unsafely operating a vehicle because you have an unexpected aneurism through no fault of your own while driving, that's different from if you are doing so because you voluntarily inebriated yourself; one is an accident, the other is negligence).

    Even worse with driving is we say that you are unilaterally not allowed to do something that by all rights should be allowed (operate a device in a safe and harmless way in a public place) unless you jump through these specific hoops. If those hoops were just a way to check yourself that you are able to operate the device safely and harmlessly, then they would be fine; if you can skip them and still operate it safely and harmlessly, no harm done, should be no crime. But instead we presume that you are unable to operate it safely and harmlessly, presume that if you operate this device you definitely will be doing something wrong, and so we make operating the device at all a crime until you can prove your ability to operate it without doing anything wrong.

    Note that this doesn't actually stop people from driving without a licence. Anybody can still get in a car with no license and drive around, and if they do so in a safe and harmless fashion nobody would be any the wiser unless they get stopped at a random check point or something; or they get stopped for one thing, and the lack of licensing is just another charge to slap on. The only crime is doing something without the state's permission, because they presume that you are unable to refrain from causing harm, even if you didn't cause any actual harm.

    To be clear, I think people should pass a driving test before they start driving. I think people should not drive under the influence of alcohol or other drugs. People should generally do the things that the law currently requires them to do, because if they don't, they will probably cause harm. And the state should punish them for causing such harm. But the state should not punish them simply for doing something that might increase the odds of them causing harm, if no actual harm was caused.

    I don't think this is a stock answer, but I expect it would be acceptable to a Biblical literalist: everything was perfect in the beginning, and things do mutate, but mutations cause "devolution", not evolution; things get worse over time. The survivors of the flood were still pure enough to repopulate the world on their own, but since then we've accumulated all these recessive defects that make inbreeding a problem. Probably because of Sin. (Cause, you know, Sin is radioactive and causes genetic degradation).

    - Why do people still believe any of this as any kind of science when it consistently and constantly refutes observable events? "The Lord Works In Mysterious Ways" is OK for a civilization that doesn't understand the world around them, but it's not like we're short on credible, observation-based theories that can explain things in much more likely terms than "Then A Miracle Happened".

Either it's impossible for information from the future to reach the past*, which doesn't necessarily mean determinism is false, just that it's insufficient for perfectly <em>predicting</em> the future; in fact, determinism basically guarantees that information cannot travel back in time except in self-sustaining ways (closed timelike curves), another classical time-travel paradox solution; alternatively, there are multiple possible futures, in which case determinism is effectively false.

If X is earlier in time than Y, then P's choice in the past is somehow being affected by what Q will tell him in the future.

Events in one time having a causal connection to events at another, or people at one time knowing about people's choices at another, don't make any difference as to whether a choice-event was free or not.

Randomness is no more freedom than determination, and adding a little randomness into an otherwise deterministic system (or adding determination into an otherwise random system) doesn't magically introduce freedom.
