Legitimacy Vs Legality

I found the below in a KDE user's blog as a comment when he discussed about the current Revolution in Egypt, crack down of the Internet and Freedom of Speech. And kind of liked it.

The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man."

G.B. Shaw

This whole talk could (imho) be shortened to : "legitimacy vs. legality".

I'm from those who think that legitimacy matters first. And the reasonable man never questions the law.
