Continuously following the first link of any Wikipedia article will eventually lead to “Philosophy.” Try it here
That's neat, but I wonder what would happen if one used some other term as the stopping term. For example, what if one followed first links until one got to, for example, English? That wouldn't work because starting with philosophy one just gets back to philosophy. For example: philosophy, rational argument, reason, rationality, philosophy.
What this is really saying is that Philosophy is a basin of attraction for first word links. So the question becomes what are the other basins of attraction?
