Philosopher Aaron Sloman claims that symbol grounding is impossible. I say it is
possible, indeed necessary, for strong AI. Yet my own approach may be compatible with Sloman's.
Sloman equates "symbol grounding" with concept empiricism
, thus rendering it impossible. However, I don't see the need to equate all symbol grounding to concept empiricism. And what Sloman calls "symbol tethering" may be what I call "symbol grounding," or at least a type of symbol grounding.
Firstly, as Sloman says about concept empiricism :
Kant refuted this in 1781, roughly by arguing that experience without prior concepts (e.g. of space, time, ordering, causation) is impossible.
