Awesome, I'll be checking this out for sure. I recently began studying computer security; do you have any more recommendations?

2Lumifer
Bruce Schneier's Applied Cryptography is a classic and his other books are also recommended.

I appreciate the initiative to send meta-sources rather than single pieces.

JMiller00

Added to my reading list, thanks!

Thanks Gunnar. Luke may not have linked his thread, because I did so in the OP.

0Gunnar_Zarncke
Oh yeah, the old problem of the visibilty of single-word links.
JMiller00

Thanks, Luke. I'll be checking your physics recommendations out soon.

If you are often travelling over bridge by car, having a car-knife could be handy in case you go over. The device generally comes equipped with a seat belt cutter, pressurized hammer, and flashlight.

Some policy issues affected by media in democratic countries: Daniel Komo argues that people hear about trade policy (I imagine this is extensible to other kinds of policy) largely because oppositions have incentive to attack government trade initiatives. But because propagating information is expensive, often opponents will focus attacks on simpler, easier to explain policy decisions, rather then ones that are more complex, since efficient use of space is cheap. He concludes that democratic political competition may lead to what I might call a kind of &qu... (read more)

Awesome, thanks so much! If you were to recommend one of these resources to begin with, which would it be?

0adbge
Happy to help! I like both Project Euler and 99 Haskell problems a lot. They're great for building success spirals.
JMiller00

I'm not. The reason I picked it up was because it happens to be the book recommended in MIRI's course suggestions, but I am not particularly attached to it. Looking again, it seems they do actually recommend SICP on lesswrong, and Learnyouahaskell on intelligence.org.

Thanks for the suggestion.

JMiller20

I am not sure if this deserves it's own post. I figured I would post here and then add it to discussion if there is sufficient interest.

I recently started reading Learn You A Haskell For Great Good. This is the first time I have attempted to learn a functional language, and I am only a beginner in Imperative languages (Java). I am looking for some exercises that could go along with the e-book. Ideally, the exercises would encourage learning new material in a similar order to how the book is presented. I am happy to substitute/compliment with a different re... (read more)

-1Douglas_Knight
Why are you committed to that book? SICP is well-tested introductory textbook with extensive exercises . Added: I meant to say that it is functional.

* I would heartily recommend Project Euler for Haskell and to anyone picking up a new language (or programming for the first time). * For Haskell specific problems, there is 99 Haskell problems. * For building monad intuition, there's a tutorial with some problems here. * This is a tutorial where you implement a Scheme in Haskell. * Programming Praxis has a bunch of practice exercises. * I haven't tried this project out, but it's supposed to allow you to work on TopCoder problems with Haskell. * There is a Haskell course with problems being put together here. I'm sure how it works, though, and documentation is sparse. * There's more advice here. * If you're looking for Haskell code to read, I would start with this simplified version of the Prelude.

Can you please explain more about "Thinking for five minutes of plans that can be executed in five minutes?"

Thanks!

7Vaniver
My suspicion is it's giving yourself 5 minutes to think of short, valuable things to do. For example, you might be planning to get dinner with a friend at a particular restaurant, and then stop to think of ways to prevent failure or make the dinner better. "I'm not certain they'll be open the day we're thinking of. It would only take a minute to call and see if they'll be open." -> "Oh, they aren't actually going to be open that day. Should we switch restaurants or days?" What's good about that prompt is that the cost of doing it is low (the amount of time you've dedicated to searching) and the search space is constrained (things that you can do quickly, which will probably be low-cost for that reason).
JMiller20

I'm not sure how comment notification works here, and whether you will auto-see what I say in other comments, but I am considering a career in software, but not as a programmer necessarily. I want to be more of an administrator/motivator, but I'm floundering in the dark as to how to go about gathering the necessary skills. Hence, I sort of defaulted to more school, since in Montreal university is really cheap. I'm still figuring things out :)

Thanks so much for the post.

2RolfAndreassen
Well, then I reiterate my comment about what mathematics background you really need: All the more so. You don't need calculus to be a programmer; there's mathematical intuition and there's "coding intuition", and both are built up by practice but they are quite different skills. And a manager needs even less to know the mathematical details. So, you may be stuck with calculus classes due to the course structure of your school, but if at your current level you can struggle through and get acceptable grades, I suggest that your marginal unit of effort is likely better spent coding. (If you're looking at a fail, or at insufficient preparation for a tougher course next year, that's a different question.) And I strongly suggest that you do not want to take courses labeled "computer science", except perhaps a very introductory one to cover data structures and big-O analysis; you want "software engineering". Possibly the courses you are taking as prereqs can be reconsidered in light of this.
JMiller00

Perhaps you are right wrt my belief that I understand concepts. An example of what I meant is; while explaining what a derivative is in class today, I understood rather easily what it is used for and how it works. However, as soon as numbers were put on the board, it was harder for me to interpret what was going on.

4mwengler
The idea of a derivative is definitely worth understanding and you can understand it without being able to do a lot of actual derivatives. Most "practice" of doing derivatives is applying a set of rules you learn for exponents, chain rule, and so on. BUT if you understand the concept, you should be able to derive some or all of these rules, which is a form of doing problems. Make sure you can derive the rule for differentiating x^n from infinitesimals, for example. That always made me happier to apply the rules without thinking I was doing something arbitrary.
JMiller00

As I mentioned in another comment, I am not necessarily looking to become a programmer. I am more interested in big-picture design and management, but I figured that I ought to get as good fundamentals as possible first.

JMiller00

I said software, but I don't think I meant programming. I intend to be in some sort of quarterbacking/ management capacity. I think my comparative advantage lies in the intersection between technical work and leadership/social skills. I figured it would be best to learn as much as I can first.

1mwengler
You'll need to do some programming to get any kind of respectable job managing or leadership. Otherwise you are in marketing, and even there if you were any good you would have some technical experience informing your bullshit.
JMiller20

That's a good idea. Thanks a lot.

JMiller00

I think the step I am worst at is not the "what am I being asked" step, but the "now that I know what I'm being asked, which formulas/ rules/ concepts am I allowed to use here" step.

2Vaniver
Typically, most mathematical operations can be seen as functions that take something of type X and return something of type Y. (For example, addition might take "real plus real" and turn it into "real".) For many problems, you start out with something of type A and need to turn it into something of type D. (For example, you might have "4-1" that you need to turn into a single number.) You can visualize this as a search problem over a network, with the benefit that you can go from both ends. You want a D, so find things that take some other argument and turn it into a D. Suppose there's only one operation you know that gives you a D, which takes a C. Now you look at operations that take an A, and see if there are any that get you closer, and find that one gives you a C. So now you can go A->C->D and be done. (The example you gave of turning "4-1=x" to "x+1=4" to "x=3" has an obvious interpretation here, and also highlights that there can be many paths through the network.) It may help to explicitly map out the things you know how to do in a given context. This isn't exactly an example of what I mean, but here's a map which shows relationships between probability distributions. For Newtonian mechanics, you might have a map which identifies every kind of useful unit, and the relationships between them (a distance and a velocity are related by a time; a velocity and an acceleration are related by a time; an acceleration and a force are related by a mass; a force and kinetic energy are related by a distance) and within them (momenta are related to each other by conservation of momentum). (The within relationships are often less interesting, but it can help to know that momentum and energy are conserved but distance isn't, say.) This sort of preparation seems useful at daisychaining- you see a momentum, and you immediately have in your mind "I know how to turn this into a force, a velocity, a mass, or a kinetic energy." As mentioned elsewhere, practice. In particular
JMiller20

Yeah, that sounds like it makes sense. Thank you.

JMiller20

I can concentrate for long amounts of time. A bigger problem is physical restlessness. I use a whiteboard to keep myself standing and moving, which seems to make it easier. My handwriting sucks, so it also lets me be a bit more neat.

0ChristianKl
As far as I understand most people use paper for solving the kind of problems that you face in basic calculus. Maybe the whiteboard is making you slower.
JMiller20

My math teacher in Hs thought I may be dyslexic, I tend to think of problems backwards and to solve 4-1 by computing 3+1, for example. I do have some trouble with directions, but nothing too debilitating.

JMiller00

Ok, I'll keep that in mind. I definitely intend to expand my horizons.

JMiller00

No, no aversion, although I sometimes feel initially overwhelmed when I see many symbols. I was one of the quickest in the class in elementary school. Didn't like or appreciate math or science in hs even though I was in the advanced group, so part of my problem stems from poor fundamentals.

Hi, I am taking a course in Existentialism. It is required for my degree. The primary authors are Sartre, de Bouvoir and Merleau-Ponty. I am wondering if anyone has taken a similar course, and how they prevented material from driving them insane (I have been warned this may happen). Is there any way to frame the material to make sense to a naturalist/ reductionist?

1ChristianKl
Ignorance isn't bliss. If the course brings you in contact with a few Ugh fields that you hold that should be a good.
4hesperidia
1. If you do not have a preexisting tendency for depression as a result of taking ideas seriously, you probably have nothing to worry about. If you are already a reductionist materialist, you also probably have nothing to worry about. Millions of college students have taken courses in existentialism. Almost all of them are perfectly fine. Even if they're probably pouring coffee right now. 2. In LW terms, it may be useful to brush up on your metaethics, as such problems are usually most troublesome about these kinds of ideas in my social circle. Joy in the Merely Real may also be useful. I have no idea how your instructors will react if you cache these answers and then offer them up in class, though. I would suggest not doing that very often. 3. In the event that the material does overwhelm you beyond your ability to cope, or prevents you from functioning, counseling services/departments on college campuses are experienced in dealing with philosophy-related depression, anxiety, etc. The use of the school counseling services should be cheap/free with payment of tuition. I strongly suggest that you make use of them if you need them. More generally, talking about the ideas you are learning about with a study group, roommate, etc. will be helpful. 4. Eat properly. Sleep properly. Exercise. Keep up with your studying. Think about things that aren't philosophy every once in a while. Your mind will get stretched. Just take care of it properly to keep it supple and elastic. (That was a really weird metaphor.)
0IlyaShpitser
I think existentialism is very compatible w/ naturalism/reductionism. Existentialists just use a weird vocabulary. But one of the main points, I think, is coping with an absent/insane deity.
3pragmatist
When reading Merleau-Ponty it might help to also read the work of contemporary phenomenologists whose work is much more rooted in cognitive science and neuroscience. A decent example is Shaun Gallagher's book How the Body Shapes the Mind, or perhaps his introductory book on naturalistic phenomenology, which I haven't read. Gallagher has a more or less Merleau-Pontyesque view on a lot of stuff, but explicitly connects it to the naturalistic program and expresses things in a much clearer manner. It might help you read Merleau-Ponty sympathetically.
3fubarobfusco
All of those weird books were written by humans. Those humans were a lot like other humans. They had noses and butts and toes. They ate food and they breathed air. They could add numbers and spell words. They knew how to have conversations and how to use money. They had girlfriends or boyfriends or both. Why did they write such weird books? Was it because they saw other humans kill each other in wars? Was it because writing weird books can get you a lot of attention and money? Was it because they remembered feeling weird about their moms and dads? People talk a lot about that. Why do they talk a lot about that?

I suspect that warning was intended as a joke.

This could be a Lovecraft horror story: "The Existential Diary of JMiller."

Week 3: These books are maddeningly incomprehensible. Dare I believe that it all really is just nonsense?

Week 8: Terrified. Today I "saw" it - the essence of angst - and yet at the same time I didn't see it, and grasping that contradiction is itself the act of seeing it! What will become of my mind?

Week 12: The nothingness! The nothingness! It "is" everywhere in its not-ness. I can not bear it - oh no, "not", the nothingness is even constitu... (read more)

One of the things I'm considering is a joint math/ comp sci degree. Thanks for the suggestion.

Hmm, that's a very interesting idea, thanks!

Great idea. I would be interested in joining. I can begin mid June.

JMiller30

Awesome, I look forward to reading this. Thanks, Luke and crazy88!

JMiller00

Viliam! Thank you!

That was very clear, except for one thing. It seems like you are conflating human desires with morality. The obvious (to me) question is: what happens if, instead of currently loving other people and being aware that I may become a psychopath later, I am a psychopath now and realize I may disposed to become a lover of people later?

I do see how any moral theory becomes deontological at some level. But because the world is complex and the human brain is crazy, I feel like that level ought to be as high as possible in order to obtain the la... (read more)

2Viliam_Bur
I am probably using the words incorrectly, because I don't know how philosophers define them, or even whether they can agree on a definition. I essentially used "morality" to mean "any system which says what you should", and added an observation that if you take literally any such system, most of them will not fit your intuition of morality. Why? Because they recommend things you find repulsive or just stupid. But this is a fact about you or about humans in general, so in order to find "a system which says what you should, and it makes sense and is not repulsive", you must study humans. Specifically, human desires. In other words, I define "morality" as "a system of 'shoulds' that humans can agree with". Paperclip maximizers, capable of reflexivity and knowing game theory, could derive their own "system of 'shoulds'" they could agree with. It could include rules like "don't destroy your neighbor's two paperclips just to build one yourself", which would be similar to our morality, but that's because the game theory is the same. But it would be game theory plus paperclip-maximizer desires, so even if it would contain some concepts of friendship and non-violence (cooperating with each other in the iterated Prisonner's Dilemma's) which would make all human hippies happy, when given a choice "sending all sentient beings into eternal hell of maximum suffering in exchange for a machine that tiles the universe with the paperclips" would seem to them like a great idea. Don't ever forget it when dealing with paperclip maximizers. If I am a psychopath now, I don't give a **** about morality, do I? So I decide according to whatever psychopaths consider important. (I guess it would be according to my whim at the moment.)
JMiller20

Hey Hen,

Thanks for your suggestion, I like it.

I see how it appears that I was begging the question. I was unclear with what I meant. When I say that "consequences matter because they are real effects", I only mean that consequences imply observable differences in outcomes. Rightness for its own sake seems to me to have no observational qualities, and so I think it is a bad explanation, because it can explain (or in this case, justify) any action. I think you are correct that I need to defend why real effects matter, though.

Jeremy

Cool, I will check him out. Thanks.

Thanks for the encouragement!

I might as well also mention also that Luke recommended a chapter from miller's contemporary metaethics pdfs linked here- Specifically, to read the section on ethical reductionism in this comment- http://lesswrong.com/lw/g9l/course_recommendations_for_friendliness/89b5
JMiller20

Hmmm that's right! I can't believe I didn't see that, thanks. I think Railton is more similar to Luke then Jackson is to Eliezer though, if I understand Eliezer well enough. Is there a comparison anywhere outlining the differences between what Eliezer and Luke think across different fields?

JMiller10

Thanks Jack. Is it ever frustrating, (or is it more often fun) to be on a forum with such a large percentage of realists?

I like the theological analogy. I need to think about it some more because I think there are some important differences.

3buybuydandavis
I think the percentage of moral "realists" is lower here than in the general population.
2Jack
Well, I stopped taking ethics classes and focused on metaphysics and philosophy of science. But that was more just a matter of interests. I got more frustrated with professors tolerating the epistemic relativism popular among students.
JMiller20

It isn't that I don't understand the sequences on their own. It's more that I don't see a) how they relate to the "mainstream" (though I read Luke's post on the various connections, morality seems to be sparse on the list, or I missed it). And b) what Eliezer in particular is trying to get across. The topics in the sequence are very widespread and don't seem to be narrowing in on a particular idea. I found a humans guide to words many times more useful. Luke's sequence was easier, but then there is a lot less material.

I think he was playing devil's advocate. Thanks for the comment.

0LauralH
I think EY's central point is something like: just because there's no built-in morality for the universe, doesn't mean there isn't built-in morality for humans. At the same time, that "moral sense" does need care and feeding, otherwise you get slavery - and thinking spanking your kids is right. (But it's been a while since I've read the entire ME series, so I could have confused it with something else I've read.)
JMiller00

Yeah, we read Railton's sophisticated consequentialism, which sounded pretty good. Norcross on why consequentialism is about offering suggestions and not requirements was also not too bad. I feel like the texts I am reading are more valuable than the classes, to be frank. Thanks for the input!

0[anonymous]
You should try some Brad Hooker. One of the most defensible versions of consequentialism out there.
2BerryPick6
To answer a question you gave in the OP, Jackson's views are very close to what Eliezer's metaethics seem to be, and Railton has some similarities with Luke's views.
JMiller00

I didn't think about it like that, that's interesting. As I said though, I don't think consequentialists and deontologists are so far apart. If I had to argue as a consequentialists I guess I would say that consequences matter because they are real effects, whereas moral intuitions like rightness don't change anything apart from the mind of the agent. Example: if incest is wrong only because it is wrong, (assume there are no ill effects, including the lack of genetic diversity), to me it seems like the deontologists must argue what exactly makes it wrong. ... (read more)

1[anonymous]
This strikes me as begging the question. You say here that consequences matter because they are real effects [and real effects matter]. But the (hardcore) deontologist won't grant you the premise that real effects matter, since that is exactly what his denial of consequentialism amounts to: the effects of an action don't matter to its moral value. If you grant my criticism, this might be a good way to connect your views to the mainstream: write up with a criticism of a specific, living author's defense of deontology, arguing validly from mutually accepted premises. Keep it brief, run it by your teacher, and then send it to that author. You're very likely to get a response, I think, and this will serve to focus your attention on real points of disagreement.
JMiller50

Thanks! That's a very good exercise to try.

JMiller10

Ah I see. What I ment by that is the tendency to argue about terminology and not content, that's all. Sorry for the confusion.

1RomeoStevens
I think arguing over semantics is a natural reaction to edge cases. The case is extreme so suddenly the boundaries of what we mean by the word "child" becomes magnified in importance.
JMiller20

Actualy, given your above comment, it is my desire to "measure" that is the problem. Your post DID do a good job of staying away from the concept, which is what you intended. I didn't realize that was part of the point, but now I see what you mean. Thanks for clearing that up for me.

"See for example, everything written about the topic"

Nice.

Right? I would venture to guess that over 50% of students in my department are of the continental tradition and tend to think in anti-realist terms. I would then say 40% or more are of the analytic tradition, and love debating what things should be called, instead of facts. the remianing 10% are, I would say, very diverse, but I have encountered very few naturalists.

These numbers might be very inflated because of the neagtive associations I am experiencing currently. Nevertheless I am confident that I am correct within ten percentage points in either direc... (read more)

Out of curiosity, where to you go to school?
JMiller10

Thanks for the idea. In a way, I think they are simillar. Normative ethics is traditionally defined as "the way things ought to be" and descriptive ethics is "the way people think things are". But, the way things ought to be are only the way things are on another level.

If you mean that I am confusing what people think with what is the case, I am having difficulting understanding what from my comments led you to think that.

0RomeoStevens
I don't think of them as being in the same bucket. Descriptive ethics to me is something like "we noticed that people claimed to value one thing and did something else, so we did an experiment to test it." And prescriptive ethics is decision theories. What gave me the idea is this sentence: "as opposed to taking account of real effects of moral ideas in the actual world. " which sounds like thinking about descriptive ethics while the post title refers to prescriptive ethics.
