Wikipedia:Comparison to Stanford Encyclopedia of Philosophy

This essay began (on March 16, 2005) as a section of criteria removed from the article "Stanford Encyclopaedia of Philosophy" (SEP). Other sections have been added, to the essay, to expand details for specific subjects.

Comparing the Stanford Encyclopaedia of Philosophy to Wikipedia
An exercise in quality assessment might suggest itself: compare what is found on various topics at the SEP to what is found here (and perhaps, as further datapoints at other online philosophy resources). For example:


 * Truth with http://plato.stanford.edu/entries/truth/
 * Axiomatic set theory with http://plato.stanford.edu/entries/set-theory/

How is one to assess the results of such an exercise? The following criteria and issues would appear to be to the point:
 * Expository quality: how much of value does the reader learn from the texts? The order in which the entries are read is very much to the point!
 * Reliability: how much trust can the reader, who typically is not an expert on the topic, place in the encyclopaedia?
 * Comprehensiveness: how many important topics are covered? Naturally, each of these resources have holes the other lacks; particularly to the point is that the index of the SEP mostly consists of entries that correspond to an article that has been commissioned but not yet accepted, meaning the reader must go elsewhere.
 * Bias: are the alternative viewpoints presented and presented fairly? Both projects handle risk of bias in a quite different manner, and it is difficult to compare like with like here.
 * Granularity: the results of the above exercise may be unfair, in that Wikipedia coverage of the topic tends to be spread out over several smaller articles, so by comparing just the pages is to compare the SEP's whole summing up off a topic with little more than the equivalent of an introductory preamble.

Errors
Although the Encyclopedia is peer reviewed, some errors slip by the process:

Case study: Wittgenstein/Russell
Another comparison was made in mid-November 2008, for the articles about 2 famous philosophers: Ludwig Wittgenstein (1889–1951) and Bertrand Russell (1872–1970).

Over a period of a few days, the 2 articles on Wikipedia were compared with the Stanford Encyclopedia of Philosophy (SEP) to analyze the differences. Perhaps the Wikipedia (WP) articles had some unsourced opinions, but the Stanford Encyc. articles for Russell & Wittgenstein were crammed with tons of opinions in them. Neither of those SEP articles would work on WP because they were far too narrow: it's the "Stanford Encyc. of Philosophy " only, and not biographies with friendships, 4 marriages or protest marches. Because Wikipedia covers everything, the WP article on Russell had 10x to 100x times more information than the SEP. As for the Stanford Encyc. on "Wittgenstein" (uber-famous guy) – that article was a bunch of opinions with very few quotes from Wittgy or his reviewers having "conundrums" about his "covering all by being silent about the rest" and other stuff typically said by a smart-alec word prankster. I would hope an article on Wittgy would quote notable people saying he played word-games trolling philosophers during his "troll period" (or such), but don't even let Stanford Encyc. try to tell intelligent people that "Wittgy was the greatest" without attempting to quote sources that Wittgy tried punking the world, when realists were "educating" philosophers that time slows down in a strong gravitational field, and atomic clocks on airplanes flying east ran 59 nanoseconds slower than clocks on Earth, etc. And, few would blame Wittgy if he went bonkers about time dilation or computers injected via needles: very few people fully understand all that. Bottom line: the Einstein/Bohr revelations by 1922 had made "philosophers" obsolete unless they spoke tensor calculus (etc.) to model reality: the English language could no longer represent truth about Life, the universe, and everything. So let's update the Wikipedia "Russell" & "Wittgenstein" articles to mention tensor calculus, which Stanford Encyc. of Philosophy probably won't cover. As it stands (in November 2008), the ''Stanford Encyc. of Philosophy seems 10x to 100x more narrow than Wikipedia, because it does not provide encyclopedic'' coverage about personal lives and other tangent subjects that affect ideas in philosophy. Philosophy cannot be covered, adequately, without including tensor calculus, the Special Theory of Relativity, the General Theory of Relativity, those megadeath weapons, and other subjects beyond the traditional viewpoints before 1900.
