"Fact 2:
Nonetheless, the world is objectively real."
I really disliked how the author randomly throws in opinions and beliefs like that in a context that didn't really warrant it. I thought I was going to read about epistemology; instead I got a summary of his worldview.
A learning strategy for history or literature: Subjective judgment is important; careful reasoning is not.
Really, careful reasoning is not required? This is patently false, and probably based on his English and History experiences in high school decades ago. I find that people who say such things rarely have adequate exposure to the subject area. Someone I encounter on a daily basis actually in the CS research community.
I wouldn't be so harsh. Yes, his choice of words could have been better. But it's obvious that to exert relevant subjective judgment you need careful reasoning. I think what he meant in this context is that you can't use deductive reasoning as the main learning strategy in literature and history.
But he isn't presenting some random opinion, he's claiming he's teaching how think clearly and one assumes he's trying to present well by example. Well, strike-three.
-- I think contrary to his rules, I don't think there is any set, global rules for presentation beyond the basic language skills he correctly says are rather in-born. What there are is a series of interlocking conventions and strategies on a per-subject and per-topic basis. Learning those well takes a long time and can't be summarized by a how-to...
I think what he meant in this context is that you can't use deductive reasoning as the main learning strategy in literature and history.
If you're not using deductive reasoning in the study of history or literature you're doing something horribly wrong. The authors statement is flat out wrong, no matter how you spin it.
1. How does that prove anything? What you are effectively saying is that standing in front of a bus will only kill you in an objective universe.
2. The comment you replied to did not state that the commentator holds that view, it was merely an observation that they didn't expect certain content in the article.
The point is not whether or not he's right (which is an incredibly tricky question, actually, when you stop generalizing in a cartoonish way), it's that he's presenting something as fact which is definitely not provable.
Provability (that is, being able to be proved by deductive means) is not generally taken to be a requirement for asserting a fact. To prove something is to demonstrate that it could not be otherwise (that it is necessary, given the logic employed and that that the premises are true).
For example, I might assert that "Tomorrow, the gravitational constant be the same as it is today." This seems like a fact: we have pretty strong theoretical justification for it, given certain empirical evidence, an assumption of regularity in nature, and the continued predictive success of the general theory of relativity. However, if tomorrow the gravitational constant is slightly different to what it is today, then although no (deductive [1]) logical law has been contravened (as would have to be the case if a provable statement turned out to be untrue), my assertion was clearly not a fact.
However, proofs (as in mathematical or logical proofs) are obtained through deductive reasoning, not inductive reasoning, as my statement was. Thus, I would argue, there is nothing wrong with presenting something as a fact which is not provable. Otherwise, we wouldn't be able to assert very much at all: the restricted epistemology obtained would rule out all of science, for starters, and might even cast doubt on certain classes of observation statements.
Of course, you may have meant something other by 'provable' than I do, in which case clarification would be appreciated, since you presumably meant something by your assertion that facts must be provable, and it would be nice to know what it was!
[1] It is controversial as to whether a general inductive logic can be formulated.
I think he is getting at the epistemological problem of first premises. If the only fact of epistemology that I accept is "I exist", the statement "Objective reality exists" cannot be proved.
I'm sure there's better formal language for this, but we could benefit by making a distinction between "facts in principle" and "facts in practice". Let's say a fact in principle is derived from a priori knowledge, whereas a fact in practice is one that we have accepted and depend on in order to make pragmatic decisions and survive. In principle, I believe that I exist but that I cannot prove objective reality exists. In practice, I accept that objective reality exists and that if I stand in front of a bus I will be hit.
His problem is even more basic than that. Axioms+rules+theorems make up a formal system, not a universe. (I can see how it's easy to confuse the two.) At some point, you must use induction & associate/identify some of its elements with observable quantities; that's what makes it a physical theory instead of a purely mathematical theory. Deduction alone gets you nowhere in the real world. And in its own domain the most it gives is consistency, not truth. I can't for the life of me understand why it's desired, or why its absence is relevant.
How is that a coherent statement? Even if a "proof" was possible (which it isn't by definition), you could just pick a different set of axioms & arrive at a different conclusion.
You nailed it. I'd like to challenge him to apply the Rule "(1) Your guesses and opinions have to be testable." I am just curious to see how he would test this guess (or opinion), and how did he promoted it as "fact".
It's kinda hard to abandon your worldview to study knowledge, when your paradigm dictates what that knowledge means to you.
I am holding a butter knife to my imaginary 3D-scanner: you have 64px^3 of the resultant image to determine the nature of the object. If you see the tip of my butter knife you'd assume it was a smooth, dull blade with a rounded form. If you saw the middle of the blade you'd know that it was serrated, but would have to speculate about the endpoints and the form of the knife. If you saw the end of the knife, you'd be hard pressed to determine its function; you'd only know that it is rounded, smooth, and roughly 1.5cm thick. Maybe you could guess that it was a knife, but you'd still remain ignorant of its greater nature.
Your knowledge consists of this tiny view of the knife, or else you're privileged to know all knowledge (so that you might approach it without a worldview or paradigm) or to know someone who does.
You cannot study knowledge without studying worldviews, or studying it with a worldview of your own.
Metaphysics is more akin to "world view" although one's epistemological opinions/beliefs are certainly informative of their prevailing ontological stance.
"If you can't figure out how to organize your material, try this: Write down ideas in random order, then sort them".
I wish they taught me to do this before the 5-paragraph essay format. The latter of which is a useless exercise that has almost no application in real-life writing.
The 5-paragraph essay isn't meant to be the end all be all but a starting point on writing your thoughts down in a cohesive manner.
Even the great essayists (MLK Jr. for one) followed this to a degree. Introduce your point, support your point, tie it all together and conclude.
You learn it in what? Like 5th grade or Jr. High? Why would it be the pinnacle of real-life adult writing? But that very simplistic structure is the basis for much more complicated essay formats that you learn about in college (Compare & contrast, cause and effect, argumentative, etc.).
The 5-paragraph essay is often the last essay format one learns seriously. We spend the most time teaching it and no other essay format even comes close. A one semester writing course freshmen year in college does not count.
Also, just because some people can run well with 10 pound weights strapped to each leg doesn't mean it's a good idea to run with weights strapped to your legs. I've seen great 5-paragraph essays, but then again, I've also seen some great Visual Basic programs as well. These things serve as great starting points, but it is important to progress beyond them as you become more educated.
I think of 5 paragraph essays as a construction used by teachers so they can evaluate how well a student is learning the process, akin to "showing your work" in mathematics. More of a scaffold for the learning process than anything else.
The 5-paragraph essay with the self-similar structure (first sentence is an introduction, body sentences have the meat, final sentence is a conclusion) leads to incredibly rigid and repetitive essays. I too wish it was more well-known that this was the most basic, paint-by-numbers way to make an essay, and not the pinnacle of writing style.
It took me years to unlearn the 5 paragraph format. I actually wish that I had been thrown into the deep end and taught to write from reading actual quality essayists like Thoreau.
A part of me feels sad that the American schooling system relies so heavily on sub-par standards to teach the basics.
me european, had to look up 5-paragraphs essay in wikipedia.
i've heard the basic "introduction, narration, .." - structure in school, but it sounds to me when you say 5para essay you really mean an essay with five paragraphs.
Popper’s principle implies: (1) Your guesses and opinions have to be testable.
They have to say what will not happen.
Beware of vague predictions that are compatible with any outcome!
But that is Popper's view as to the demarcation of science. Popper was not of the view that science is the only realm of legitimate knowledge. And it's in conflict with:
If all knowledge depends on physical measurement, then not only do you lose truth, beauty, and love, you also lose mathematics, logic, and even epistemology!
Truth, beauty and love can be tested. If I think someone loves me, I can hug them and see how they hug back. If I think something's beautiful, I can hang it on my wall next to something else I think is beautiful, and see if I still like it next week. Truths can be tested by finding & testing physical implications of that truth. None of these tests are absolute Popper-grade refutations, but they're good enough to be useful.
Startups are generally based on some hypothesis (like "people want to communicate by multicasting 140-character messages"). Not refutable, exactly, but testable by building a company around it. Smart founders keep track of their hypotheses and are always looking for evidence for and against them.
"Beauty" is an aesthetic concept of the mind that varies between each person, not a property that you can give to an object. The object is beautiful because its perceiver finds it to be so; without the perceiver, there is no beauty. Therefore, it is a mistake to talk about beauty as an intrinsic property ("X is beautiful") when it is actually a perception ("Jim finds X beautiful.").
When we say "X is beautiful", it is actually shorthand for "Lots of people find X beautiful", or "The consensus is that X is found to be beautiful".
'"Beauty" is an aesthetic concept of the mind that varies between each person, not a property that you can give to an object.'
Not everyone would agree to this. There are people who believe that objective beauty really is "out there" in the world, independent of human judgement.
Your opinion is very fashionable at the moment, particularly among academics and intellectuals, and similar arguments are applied to morality and anything else not subject to empirical investigation. But as I said, this way of thinking is by no means universal.
But what, other than intelligent beings, can ponder the concept of beauty? When we say something is beautiful, we mean it is aesthetically pleasing, and without a perceiver of an object, there is nothing to be aesthetically pleased.
If you believe in god, space aliens, etc., we can shift the admirer of beauty to another perceiver, but still, without the perceiver there is no concept of beauty ascribed to the object.
If I like ugly things, great. I can find art I enjoy for cheap.
People are weirdly insecure about their taste in visual art. Nobody worries "Uh-oh, what if I like music that's actually bad?" I guess at least with bad music, you feel like you have company. If you're into Eminem you'll meet other people with Eminem T-shirts, but you don't see people with Thomas Kinkade or Jeff Koons T-shirts.
Exactly... and so it's possible to have other knowledge that can not be tested. I would just add to not be naive enough to believe everything you touch is this very rare special kind of truth. It's a dangerous blind path we'd walk then.
Really strong beginning just to spoil it in the second part with his own opinions about the scientific method and how to make conclusions.
In my opinion this single topic is impossible to fit in a presentation. A book is more reasonable format. I would recommend "Zen and the Art of Motorcycle Maintenance"
I found it easy to read, my eyes tend to wander when reading black text on white, maybe I have ADD or something, I found the huge white text on the dark red background easy to read, relaxing. Weird.
There's probably a deep insight for AI to be had by whoever discovers why verbose, repetitive writing is easier and more "natural" than taut, clear prose (which is "unnatural" insofar as it is rare and hard to achieve).
Not some folk-theory or heuristic, but actually understanding the mechanism.
You dislike verbose, repetitive writing because its information content is low. Taut, clear prose has high information content. The taut, clear prose you are talking about is usually higher in total content than masses of verbose, repetitive writing, despite the quantity of words. I mean "information" in the information theoretic sense, especially in the semi-informal "extent to which the words are a surprise" sense (which I find the most useful formulation for measuring English text, though note there's a relative component to that definition).
It is not surprising that more effort is required to create more information. I don't see where we need a new theory here.
I wasn't clear or you're blurring information content and density and thereby missing my point (!). Consider:
- VERBOSE: “One of the best things you can do for
yourself to improve your writing is to learn
how to cut out words that are not
necessary.”
- TAUT: “To improve your writing, cut out
unnecessary words.”
In at least the senses I care about I don't see any information in TAUT absent from VERBOSE; if you see any such information TAUT please do point it out.
Which is what I was getting at: TAUT prose communicates identical thoughts with fewer words; why is it so difficult and unnatural to generate?
I find this curious. I now have some suspicions but nothing extremely well-formed.
(!) You'd be right that in the context of essays-for-school the target wordcount is predetermined and information is expensive so the lazy satisfy the requirement(s) with the verbal equivalent of double-spacing + jumbo font.
In verbose form, it's almost like letting your thoughts spew onto the page directly. With taut writing, a lot of that mental clarification is done in your head before it hits the page.
But it's not necessarily true that if "verbose
repetitive writing", has less information content than
"taut clear prose". They could have the same information content, just the former has used more bits to describe the same information (i.e. is less compressed). I guess his question is why
some people naturally produce the former and not the latter. Perhaps they just haven't performed the necessary computation required to compress the information while they were learning it, i.e. compression could either take place while they are storing the information in memory, or else during the editing process.
It depends on the goal of your writing. Concise writing with minimized wording and maximized content is good for informative writing. However writing a book or a paragraph to cause or reflect emotional effect does require additional unnecessary words and possible redundancy
Less verbose and more information rich writing requires a more nuanced and deeper command of the language. Think of it like a compression algorithm. Algorithms that can encapsulate more information in a smaller file size are much more complex than less information-efficient algorithms.
"Instead of doing what’s easy for you, do what’s easy for your reader."
It is easier for the author to convert the PowerPoint into a PDF, but what is easier for the reader is if the information was in HTML/web format. The author should package the information so that it enters our heads as easily as possible.
This is why user-centered interfaces are better than programmer-centered interfaces. The point is to make it easier for the user, not easier for the programmer.
Indeed. You're taking the effort of making it once, but the collective readers are taking the effort of reading it tens, hundreds or thousands of times.
The five steps in the writing process: Planning, Drafting, Revising, Editing, Formatting.
Formatting is last. This is why I like to write in plain text (I use emacs, but that's not really important). When I use something like MS Word, formatting is in your face from the get-go (probably 80% of the toolbar and menu items concern formatting), and I tend to sidetrack into formatting too much at the expense of properly organizing my ideas.
This strikes me as a mechanistic, black-and-white view of certain aspects of thinking and learning that are, in reality, replete with many nuances, qualifications and caveats. It's a classic case of simplistic, Philistine shotgun approaches.
His disdainful view of the value of rhetoric and vicious hostility to the achievements of high culture, or the use of language in artistic ways to express in more aesthetically appealing ways thoughts that can be expressed more "simply" toward largely semantically equivalent ends (from an empirical perspective, anyway) also rubs me the wrong way.
I mean, sure, saying something as tersely as possible is often valuable and a good lesson to teach. It is also often the wrong thing to do or, more likely than being flat-out wrong it simply has costs as well as benefits. What precisely those are depends on what you're trying to achieve with your writing.
Should one take Dr. Covington's suggestions when writing a novel, an interesting anecdote, or a persuasive expository essay, even if one is otherwise partial to the goals of clarity in the thinking and writing that goes into it? Do most writers we consider interesting, compelling, thought-provoking, intriguing, entertaining, etc. follow his stylistic suggestions? Would their writing conserve those essential qualities if they did?
In short, while his objectives may be good lessons for people that write in unclear, logically incoherent or circumlocutory ways, he seems to tend toward very extreme reductions. It is a necessary part of intellectual development to learn to grapple with the complexity that inheres in many facets of existence, and that includes gestalt complexity that cannot be reduced to very simple atoms as, for example, in the ontology Functional Programming preaches. The world is not a giant software construction.
By his own criteria, I am taking the title of his presentation literally and denotationally, in the most simpleminded, straightforward and unambiguous way possible. After all, if he doesn't quite say precisely what he means, he's not writing very "clearly," is he?
He purports to teach me to "How to Write More Clearly, Think More Clearly, and Learn Complex Material More Easily."
Yup same here. I found it much easier to read white on red.
In my experience, to write better, you need to write more. Starting a blog about something I love has greatly improved the quality of my written communication.
Having learned English as a second language, I actually pronounced it "Wedness day" for some time before finding out how it was supposed to be pronounced... I think. That was a while ago.
Perhaps that's why many foreigners write much better English than natives: they don't get to find out the pronunciation before they see the word in writing.
I find his views on learning from text books vs reading
literature interesting. The problem I have with this self directed kind of learning is that sooner or later I always get stuck and have no one to ask questions to. For example, I'm currently going through this book on neural networks that someone posted last week (http://page.mi.fu-berlin.de/rojas/neural/). However, when I get to the exercises at the end of the chapter, I inevitably fail to complete some of them. Most of the time I don't even want the answer, since that defeats the purpose, but some kind of hint to get me going in the right direction would be really useful. It would be perfect if you could just
ask someone who knows the area. Anyone doing a lot of self directed learning from text books with suggestions?
I spend a lot of my free time doing self directed learning from text books and frequently hit a wall where I don't know where to even begin.
Usually I recognise this as either an incomplete understanding of the topic, or a representation of the problem that I'm not familiar with.
When this happens, I usually make a note of the question or topic, and specific questions I have that are preventing me from understanding the problem, and I seek out different sources of similar knowledge.
I find different authors present ideas and concepts in different ways, and sometimes if a concept isn't clear in one text, it's clear in another.
In your specific example, I'd recommend seeking another book or article on neural networks and skim it until you find information on the concept you're stuck with, and see if it can add any pieces to the puzzle.
If that fails, sometimes just forgetting about it and proceeding will unlock understanding at random later on, usually in the shower in my case.
> If your writing is nonsense, maybe your thoughts are nonsense too!
I was in a meeting at VeryBigCompany where someone presented a PRD for review. A large Word document, projected. In theory this is a high leverage document; getting things right would make life easier downstream.
I noticed a few spelling errors, and gently pointed them out. I was ignored. Unwisely, no doubt, I sharpened my voice a bit and repeated the comment. The author recorded my comment with the air of someone humoring a small child.
Next I noticed grammatical errors. Some sentences had two plausible meanings; some had none.
To the other participants, the important thing was that the PRD touched on the key concepts. My focus on minutiae was inappropriate.
But to me, the flaws in expression signified flaws in thinking. I think Covington was right in this case, and the thoughts were nonsense too.
I used to think like you, until I started working with some brilliant people who can't spell, or produce grammatically correct writing, to save their life. Be careful with that indicator... it's far from a surefire signal.
That is so true. My partner in business is a lady that is dyslexic, but extremely smart. If I would be distracted by her spelling I'd miss the good stuff in the message
It's very important to remember that language is a tool for communicating ideas, if you focus on the language as the 'end' you are forgetting it is only a 'means'.
Even brilliant people can use a spell checker. And if you are presenting at any sort of formal meeting, wouldn't it be a good idea to show your presentation to someone before the main event?
The fact that you can't spell doesn't mean you're stupid. The fact that you are unable to find a way to correct your spelling does.
Spell checkers don't help with this level of poor language. And these people do use me as an editor when doing presentations and the like. But I get to see the full gory disaster that is their initial version, and what I'm saying is, I've learned not to discount their intelligence based on that.
I enjoyed this overall, but I just want to point out that he didn't really make an argument against moral relativism, just said "practically, that's dumb." Most moral relativists [that I know] aren't so concerned with practice—they're instead trying to explicate that human sentient culture is just one possible variety of sentience in the universe. For example: if we could make exact copies of ourselves (incl. knowledge et all), would that be a good idea? Well, we have one moral viewpoint; the people we will be when we need to answer that question, though, will have different cultural biases—that is to say, context—than us. The universe has as many definitions of "good" or "bad" within it as there are ways to compose a utility function.
"Because the world is objectively real, of course some things are better than others, by any reasonable criteria."
Given a set of criteria with objective measures, one can objectively tell if something meets those criteria, or not, or whether it meets more of those criteria, or not. But words like better and good express emotional value judgements. It is, as far as I can tell, impossible to prove that my criteria for what makes something good is objectively better than yours.
E.g., I may think food A is better than food B because it is spicier. You may may think food A is worse than food B for the very same reason. How do you determine whose version of better really is?
Does anyone have a good tool for jotting down ideas and rearranging them? I find that word processors are not very good for this, because they are more concerned with formatting than manipulating units of text. Simplicity is paramount.
Org-mode in Emacs is brilliant for this. Write things as outlines, shift sub-trees around trivially, fold (hide) and un-fold (reveal) subtrees, embed links within your outline, export to text or HTML when needed.
If you don't know emacs and you already have Word you could use the outline mode of it. I have used it in the past and it works pretty well. I haven't sat down and learned emacs so I have yet to try org-mode but I hear that works well too.
I have yet to find a truly great outlining program yet. (Note: I plan on learning org-mode emacs but I am a vim guy so the initial inertia of learning it is high.)
I don't really understand why this got 100 points. It's a passably good presentation, at least for the first half, but serving it out as a pdf was silly (why not just upload it to slideshare if you must share it in slide form?) and it really degenerated into randomness as it progressed.
It's alright, but not good enough to deserve top spot on HN for hours. Maybe it's just a really slow news day for HN.
Very good. The 25->8 word exercise was a good little demo.
Though I smiled when I saw "if you can spell ... int main(int argc; char* argv[]);" -- his first semicolon should be a comma in C. Also: the world is (more or less) spherical, not round. :-)
Actual quote: "Instead of doing what’s easy for you, do what’s easy for your reader."
But that actual quote is an important point, expressed in few words: many inexperienced writers are "in love with the sound of their own voice" and forget to put themselves in the position of the reader.
I really disliked how the author randomly throws in opinions and beliefs like that in a context that didn't really warrant it. I thought I was going to read about epistemology; instead I got a summary of his worldview.
