The comic XKCD recently published a strip which in the hidden text claimed that if you started on any page on Wikipedia and clicked the first link that wasn't in italics or brackets and do so in each article that comes up from that initial click and you will always eventually end up at the article about Philosophy.
So I thought I would test that out.
Let's see... let's start with Samuel L. Jackson
Samuel L. Jackson
Civil Rights Movement
It is just that easy!
It is a fun little experiment, though I think I know the pattern (since most of my searches end up at science and then trickle down to philosophy following that). Since tangible ideas are based on ideas, deep down they all end up boiling down to philosophy if you keep clicking through.
Try it yourself. Come on, you know you want to!
