On this issue, we can distinguish 4 approaches: (1) let symbols get their meaning through "interpretation" (provided in another language) --- this is the approach used in traditional symbolic AI.
(2) let symbols get their meaning by grounding on textual experience --- this is what I and Kevin suggested. (3) let symbols get their meaning by grounding on simplified perceptual experience --- this is what Ben and Shane suggested. (4) let symbols get their meaning by grounding on human-level perceptual experience --- this is what Brooks (the robotics researcher at MIT) and Harnad (who raised the "symbol grounding" issue in the first place) proposed. My opinion is: in principle, the approach (1) doesn't work well for AI, while the last 3 approaches are in the same category. Of course, the richer the experience is, the more capable the system will be. However, to actually develop an AGI theory/system, I'd rather start with (2), and leave (3) for the next step, and (4) for the future. Therefore, though I basically agree with what Ben and Shane said, I won't do that in NARS very soon.
