Definition of Symbolic AI Symbolic AI people are touchy about defining their subject. This is due to Symbolic AI having been more of a craft arising from a technology than a science with a philosophy. Whereas a science would be concerned with principle, and in particular with definitions, Symbolic AI has grabbed concepts from where it can find them and put them to work in its techniques. Artificial Intelligence is the study of ideas that enable computers to be intelligent. From this we glean the notion that AI is to do with artefacts called computers.
Intelligence remains undefined.
People's natural ability to recognise intelligent things 'defines' intelligence without any reference to any principles. The classic AI definition. A somewhat offbeat definition which is nevertheless important. The referral to the current moment seems a little awry. The essential point is that AI should be intelligence as far as the artefact is concerned.
