Intelligence: Natural, artificial, or what?

We consider the competing attributes of natural intelligence (NI) and artificial intelligence (AI). Attention is paid to conceptual, theoretical, stylistic and aspects of both, and non-human intelligence. Intelligence is related to information processing and current views of physical structuring. Means of distinguishing between NI and AI are noted, and neural and digital structures are described. Pribram's bi-computational neural networks are introduced, and high-level computation is discussed. We describe the hierarchical Aquarium scheme, along with an AI implementation, and conclude with a proposition for future based artificial intelligence.
