Subject: Re: becoming a better programmer From: Erik Naggum <firstname.lastname@example.org> Date: 18 Sep 2002 14:29:27 +0000 Newsgroups: comp.lang.lisp Message-ID: <email@example.com> * synthespian | There's one thing that I definitely think is a basic flaw with ontologies, | at least the way they're set up (I may have a very limited understanding on | the topic, however): the ontology is defined by the "definer". That is, it is a flaw in the system that it is designed by humans for humans. This is an age-old philosophical problem which I personally consider totally nuts. We /are/ humans. This is /not/ a flaw. We take what we have and deal with it. Wishful thinking and dreaming about changing the human condition may be fun, but it is not productive. | For example, the person who defines the ontology has motives for indexing | something in the ontology. Why does he/she do it? What are the "economics" | or "psychology" behind it? This is relevant, as anyone who works with | narketing will tell you. So you have at least discovered that all human knowledge is contextual. This is a good step up from the desire that human knowledge should be acontextual or absolute, a desire which has frustrated people for ages when they do not think things through. Coupled with a "magical" weltanschauung where things become what we think about them, there can only be chaos. But there is a different fundamental outlook on this: The world out there is the same for all people, and no matter which contorted approach you take to grasp it, you will, eventually, end up with the same knowledge as everybody else. The real question is whether there you can find ways to approach this whole knowledge thing that would result in fewer blind alleys and false starts, and there is. This is what philosophy is all about, or at least the branch of it called epistemology -- or the study of how we know what we know. I know of no serious effort to study epistemology that has ended up with the same kind of "magical" weltanschauung that people who have not studied it, but have sort of adopted the pre-scientific model of religions, tend to hold. | Another thing is the very meaning of a word. How then, does he/she | understand the meaning of the word? Words change meaning over time, a fact | any linguist will tell you...And, if that wasn't enough, they mean different | things to different people. I'm not talking about you defining that <zp> | means <zip code>, but the very concept of zip code (ok, my example isn't so | good. But let me give you a *real* example: a sociologist here in Brazil | set out to discover what percentage of the population understood the correct | meaning of the concepts of "right" and "left" in politics...A total | disaster...An amazing amount had no clue, and actually exchanged meaning. | Now imagine a candidate for the the congress asking for votes...you get the | picture...) No, on the contrary: I think you show a massive lack of insight into these issues, and thus react with fear, uncertainty, and doubt about issues that are not only taken well care of by professionals who know their business, but never actually arise in practice when the system is used by skilled users. And believe me, if you are observant and wish to understand, instead of approaching a system with preconceived notions that how you have done things up until now is flawless and perfect and anything that deviates from it is bunk, it takes very little time to understand Dewey or the Universal decimal classification well enough to predict where you will find things. For the fine-grained classification of new works, however, it takes serious investment in studying it and discussing with other classifiers. This is, after all, social engineering. I think most of the problems you allude to actually come from the desire to see a system usable in a vacuum by one person with no prior exposure to the system. I believe that novices should be willing to learn something rather than be willing to judge something they do not know. I realize that I am in the minority in this modern world where many people think that not knowing something is superior to knowing it, at least morally, and that the only people you cannot ask if you want to know something are experts in the field. This anti-rational, anti-intellectual, anti-knowledge stance is not usually conscious, however, and most people will deny that they have such attitudes, but still act on them and feel much "safer" if they ask some fellow ignorant than if they ask an expert. It has puzzled me greatly for as far back as I can remember. None of the experts I have asked have been able to give a good answer. [Pause for effect...] The people who tend to feel this way, however, are usually unable to argue for it, because as soon as they start to think, they move into the rational world where their attitudes are very different from their default non-thinking ones. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
