Re: Limits of Knowledge

I noticed that most contributors are happy to show off what they know, but are less up-front about what they don't know. Especially in science, only a few are willing to admit ignorance. As Wiki is for everybody, I would suggest to frame content more in terms of what we know and what we don't know. This might help avoid intimidation of simple minds like mine, and help knowledge seekers get a better picture of the limits of knowledge and the challenges ahead.--Robert van der Hoff 01:13, 4 May 2007 (UTC)[reply]

We have some lists of unsolved problems in various fields; this sounds like the the sort of thing you're looking for – Gurch 15:25, 5 May 2007 (UTC)[reply]

Thank you for pointing me at the list of unresolved problems. I browsed through them, and found them varied in style and substance. On the one hand, there are some very technical lists that are practically meaningless to the uninitiated, and on the other hand, there is the item on unresolved philosophical problems which is an article in itself. I could add a few that are not listed, and I don't dare to classify them as physical or philosophical: Where does energy come from, has it always been there, and why does it exist?--Robert van der Hoff 05:12, 7 May 2007 (UTC)[reply]
