A general model of primitive consciousness

We present a simple model of consciousness as it may exist in animals and can exist in man-made artifacts. The minimum unit of consciousness is a brain/body in interaction with a world. No parts of that system are themselves, conscious. Emphasis is placed on structures that could have evolved from earlier structures by small steps each of which conferred advantage to its possessors. The model is functional, so it becomes possible to build such conscious systems. Indeed, we show why conscious systems should be built as well as how humans should interact with them.
