> particularly in these times when knowledge is so vast and there is so much to read. I come down on the other side of this. The implicit assumption here is that more is better, but it's like drinking from the firehose. > The principle to keep in mind is "Knowledge for Knowledge sake." The other position is that knowledge is only useful if it lets you do something that you couldn't do without it. If you're gaining knowledge for the pleasure of gaining it, and I see no need to justify why one would do this, then whether you read deeply or read widely doesn't make much of a difference. But if you want to do something with that knowledge, the approach you take should be informed by what you want to do.

> The implicit assumption here is that more is better, No, that is the assumption that you are making and not what i meant. It is an undeniable fact that today we have a far far greater amount of Scientific and Technological Knowledge (sheer Data without making any value judgements) than in any time in the past Human history. Our Society's dependence on Science/Technology has also increased exponentially since the beginning of Industrialization thus forcing us to know/learn more and more.

This is a very limiting viewpoint which is what the posted article and my comments are arguing against. The utility of some knowledge may not be apparent at its inception but may turn out to be of utmost importance when other fields have also developed so everything can come together into a greater whole.

  > It is an undeniable fact that today we have a far far greater amount of Scientific and Technological Knowledge I don't dispute it. What I dispute is the implication I believe your proposing, which is "there is more knowledge, and therefore we need to read broadly and not focus as much on deep understanding". If that is not what you mean, please correct me since I don't see what other implication you mean. > The utility of some knowledge may not be apparent at its inception but may turn out to be of utmost importance when other fields have also developed so everything can come together into a greater whole. I don't disagree. But to apply this knowledge later you need to have remembered about it, and writing notes (which is where this discussion started) absolutely helps with this. I'm arguing for writing down the concepts that you found important or interesting at the time, not a synopsis of each subchapter. > The justification has to do with getting exposed to a greater amount of concepts/ideas and not necessarily understanding/assimilating everything. Here reading widely does make a difference. But reading widely only makes a difference to the degree that you do assimilate the content and that it changes you. > Many a time in scientific research one does not even know the utility of something until sometime in the future when things align correctly. Except we are not talking about doing scientific research (where I agree getting more knowledge is the whole point). We're talking about reading other people's work to get something out of it. And, especially, in this context there is a trade-off between "just in case" knowledge and "just in time" knowledge.

    > which is "there is more knowledge, and therefore we need to read broadly and not focus as much on deep understanding". If that is not what you mean, please correct me since I don't see what other implication you mean. I did not say "not focus as much on deep understanding". I am only talking about exposure to all sorts of concepts/ideas. When the time for application of knowledge comes, depth will be achieved as a matter of course since it becomes a prerequisite. Reading broadly and widely for knowledge (so to say to get a map of the terrain) is different from reading deeply for a specific objective/need and has to be cultivated consciously. > But to apply this knowledge later you need to have remembered about it, and writing notes (which is where this discussion started) absolutely helps with this. I'm arguing for writing down the concepts that you found important or interesting at the time, not a synopsis of each subchapter. I think maybe you are confusing my comments with somebody else's and meant this as a reply to somebody else? I have not mentioned note-taking in any of my comments in this thread. However, In past HN threads to do with note-taking, i do argue for the benefits of this discipline but in the context of this thread i am only arguing for "Reading broadly and widely" (with/without note-taking). > But reading widely only makes a difference to the degree that you do assimilate the content and that it changes you. No, mere exposure and fuzzy understanding is many a times good enough. Assimilation can be superficial or in-depth as needs dictate. What Reading widely/broadly enables is to see interconnections/interplay between various subjects the very existence of which you might have been unaware of earlier. This is particularly true in today's times where there is so much knowledge that it is impossible to go deep into everything. > Except we are not talking about doing scientific research (where I agree getting more knowledge is the whole point). We're talking about reading other people's work to get something out of it. And, especially, in this context there is a trade-off between "just in case" knowledge and "just in time" knowledge. I was using the example of "Scientific Research" since it is the classic textbook exemplar of knowledge before utility. But the same idea is also applicable to reading various subjects. It is also the case that "just in case" knowledge will generally always trump "just in time" knowledge. As an example, you can write software without knowing anything about predicate logic/formal methods. There is no "just in time" to acquire this knowledge unless you happen to work on projects where they are needed (a very small percentage). But if you were to study this "just in case" and even if you don't use it rigorously the very act of knowing it will allow you think about program construction in a whole new light which will give you superior insight and increase your effectiveness/productivity immeasurably.
