There may be more usefully discriminable levels of abstraction than those. Where to draw the line between thought and unthought? It seems an uninteresting question to me. Should I draw a line between the United States of America and the people thereof? They are distinct, but the latter is a part of the former, and without their aggregate the former would not exist.

Usually I equate thought and consciousness, but perhaps there is a useful distinction there?

In mammals sentience precedes consciousness precedes sapience. In machines the necessity of the linkage is not clear. We can imagine sapience without consciousness, at least, but consciousness without sentience seems more questionable.
