In Proceedings of the twenty-sixth Australasian computer science conference on Conference in research and practice in information technology, Adelaide, Australia (pp. 55-60). Darlinghurst, Australia: Australian Computer Society, Inc.https://hdl.handle.net/10289/1391In response to Searle's well-known Chinese room argument against Strong AI (and more generally, computationalism), Harnad proposed that if the symbols manipulated by a robot were sufficiently grounded in the real world, then the robot could be said to literally understand. In this article, I expand on the notion of symbol groundedness in three ways. Firstly, I show how a robot might select the best set of categories describing the world, given that fundamentally continuous sensory data can be categorised in an almost infinite number of ways. Secondly, I discuss the notion of grounded abstract (as opposed to concrete) concepts. Thirdly, I give an objective criterion for deciding when a robot's symbols become sufficiently grounded for "understanding" to be attributed to it. This deeper analysis of what symbol groundedness actually is weakens Searle's position in significant ways; in particular, whilst Searle may be able to refute Strong AI in the specific context of present-day digital computers, he cannot refute computationalism in general.application/pdfenThis is an author’s version of an article published in Proceedings of the twenty-sixth Australasian computer science conference on Conference in research and practice in information technology.
