Hal Finney quotes:

Bitcoin seems to be a very promising idea. I like the idea of basing security on the assumption that the CPU power of honest participants outweighs that of the attacker. It is a very modern notion that exploits the power of the long tail.

Since we're all rich with bitcoins ... we ought to put some of this unearned wealth to good use.

The computer can be used as a tool to liberate and protect people, rather than to control them.
