From Spider Solitaire to Philosophy – and Back Again

And now for something completely different:

Let us try the following experiment. We start with the Wikipedia page on Spider Solitaire and then do the following:

  • click the first link of the “main text” (but ignoring anything in parentheses).
  • Rinse
  • Repeat

From the screenshot below, step 1 says should click on the word “patience”


After a few iterations we reach a closed loop of the form Philosophy > Existence > Ontological > Philosophy.

The interesting phenomenon is that the starting point is almost always irrelevant: if you pick a random page then it is heavy odds on you reach the same closed loop involving “philosophy”. Not surprisingly, Wikipedia itself has a page on this phenomenon and it is estimated (as of February 2016) that 97% of all articles in Wikipedia lead to Philosophy. The remaining articles either lead to “sinks” (no outgoing wikilinks), non-existent pages or closed loops other than Philosophy. This phenomenon was pointed out to me by someone from Adelaide University on the 4th of March.

Just for the record, here is the chain that starts with Spider Solitaire. I will not discuss this chain in detail – the reader is invited to draw his or her own conclusions:

  • Spider (solitaire)
  • Patience
  • Card games
  • Game
  • Play
  • Intrinsically motivated
  • Desire
  • Emotion
  • Biological
  • Natural science
  • Branch of science
  • Sciences
  • Knowledge
  • Facts
  • Reality
  • Imaginary
  • Object
  • Modern Philosophy
  • Philosophy  > existence > ontological > philosophy

Being a self-proclaimed Grand Master of Spider Solitaire, I am more interested in the reverse process. Starting from the Wikipedia page on Philosophy, is it possible for me to choose any outgoing links of my choice (not necessarily the first) and eventually land on the Spider Solitaire page? I don’t have a definitive answer. All I know is the random link algorithm proposed by my good friend Ninja Monkey doesn’t work so well!

If anybody can find a path from Philosophy to Spider Solitaire I will be happy to grant said person the title of Great Grand Master of Spider Solitaire. Challenge accepted anyone?
