I'll put up a paper saying "ACX Meetup" so you know who to wander over to.

We'll meet at the library and then head over the Pho place for lunch.

Is the goal of all this persuasion to get people to fire off a letter like the one above?

Thanks, I've fired off a version of this to my three representatives.  I'm going to pass out copies to my friends and family.

I think I can express Sam's point using logical argumentation.

1) Your internal motivational structure is aimed at X.

2) Y is a pre-requisite for X.

3) You ought to do Y in order to achieve X. (This is the only sense in which "ought" means anything).

First time post! I signed up just to say this. If there's a problem with the formulation I just described, I'd love to know what that is. I've been confused for years about why this seems so difficult for some, or why Sam can't put it in these terms.
