Dr. Furukawa had a sharp view in pinpointing that the crucial issue in skill science lies in discovering missing parts, that it is an act of abductive thinking, and that logic programming can be best used to encourage people, who intend to learn embodied skills, to think and feel more than without it. In the wake of the grief that our communities lost Dr. Furukawa, discussions on implications that his great contributions to AI, cognitive science and skill science have brought to us are a necessary “must” for all that keep doing researches for people’s well-being.
