# Quote — Robert A. Heinlein, The Moon Is a Harsh Mistress

> I'm a Fifth Internationalist, most of the Organization is. Oh, we don't rule out anyone going our way; it's a united front. We have Communists and Fourths and Ruddyites and Societians and Single-Taxers and you name it. But I'm no Marxist; we Fifths have a practical program. Private where private belongs, public where it's needed, and an admission that circumstances alter cases. Nothing doctrinaire.
