But we should also tempter our expectations because of how we know liberal societies work. In a free market there's competition, and the winner isn't always the best in all respects.

An idea that may work for a counterculture may fail as a culture for those who lack elite discipline or resolve.

But it's an interesting question: How should humanists try to convert others to their way of thinking?
