Nearly 30 years ago I wrote a piece for Sociological Research Online entitled: ‘Simulation - A Way Forward?’ One thing I will do in the closing plenary is reflect on how what I have heard and seen informs an answer to that question today, but here are some things to note which whilst I do believe in the great potential value of simulation as a tool of social science still at this point remain issues for me given that like Paul Cilliers I believe that modelling complex systems is impossible but nevertheless we have to model them: getting beyond a micro-emergent account; developing an understanding of the role of social structures which gives them causal  powers; enabling an account of how power works in relation to the capacity of agents to shape social structures; writing nature and its power into our simulations.
