AI with common sense:what concept of common sense?

Common sense is a theme that is present from the very beginning of artificial intelligence (AI); it was claimed already in 1958 that a particular computer program displayed ‘“common sense’”. However, what is ‘“common sense’” (CS), we must ask? This chapter lists and seeks to clarify eight different concepts of ‘“common sense’”. These historically derive from three historical types: Aristotle's ‘“koine aisthesis’” of sensory integration, the ‘“natural reasoning’” of the Scottish Enlightenment, and Vico's ‘“‘‘un-reflected moral community’’” which is both universal and culturally distinct. We also capture the tension of positioning CS in a vertical hierarchy or on a horizontal continuum of different forms of knowing. Being aware of different concepts of CS will enable us to assess critically claims made as to AI with CS’”: which kind of CS is invoked?
