I believe there is a method to his madness, and it is madness. Every country has their own ideologies in place, which requires him to make adjustments in his pursuit of the end goal. However, IMO, there is a coherent and consistent ideology on his part and it is very frightening.

I met some of the OSI guys when I was in Hungry, we (my class) stopped by Central European University (which he basically founded).
It was a weird group, but in essence, they know one thing clearly, he is nuts.
They talk well of him, but in private, they think he's pretty much lost it with his "messiah complex".
He is also not known for long term thinking, and moves from one cause to another.
The OSI guys (the ones I met) over there, were actually big supporters of Free Market principles and believed that a big government (or activist government or strong centralized government) was an enemy to the beliefs of an "open society".
Bizarre guy, and no one takes his "philosophy" junk seriously, even Paul Krugman, who is nice to him, and usually says positive things about, has also hinted that Soros isn't exactly trustworthy in some writings noting him. Interestling, he held a debate with him once.....and lost.
