AI with its emphasis on reasoning with abstract symbols. There is also the Connectionist approach, with its exploration of the synergies of many interconnected simple structures. ``Nouvelle Robotics'' with a focus on the interplay between systems generating skill or behaviour in complete agents - there is scope for considerable argument about principles, research programmes, and the Nature of Things. There is also of course, room for compromise and synthesis. This collection of papers, presented at AISB95 (the 10th biennial conference on AI and the Simulation of Behaviour) reveals both argument and synthesis.
