This is what I propose we call the idea that if an idea excites emotions in you, that it is good. The background, of course, is the movie portraying the gradual indocrination of a postman by a Communist (resulting in a scene we never see in his death while participating in some act of violence).
Perhaps we could oppose theatricality to practicality. This works well, for example in contrasting Hollywood with rural Iowa. Fields don’t plow themselves, and cows don’t milk themselves. Neither cares about the emotional committments of the farmer, or how good his intentions are.
But for their part the actors can farm an almost infinite array of emotions resulting from the joy they feel in contemplating themselves contemplating helping people.
Thoughts can only be works of art if they work. Everything else is show, and belongs in playgrounds, not the academy or the halls of power.
