There are a number of approaches to this question, Jo; but essentially and in summary (and i do a great injustice to a very powerful philosophical school), the deterministic tradition suggests that since we''re fundamentally bounded chemical systems immersed in a "sea" of ever more elaborate chemical processes, regulated by immutable (replicable and predictive) physical laws, and nothing else (which takes you back to the mind/brain question), our actions are no more than expressions of these chemical processes, constrained at an aggregate level by universal physical laws. When we think we make decisions based on choice, it is the mind "stroking" itself since, in terms of "proximate" action, we know that our decisions are preceeded in time by a neuro-electrcal "footprint" (interesting work by Benjamin Libet, presented in his book "Mind Time"); and in terms of more deliberative action, we are pretty certain to make the same decisions over and over again given the same set of variables, since our cognition is hard wired, and its operations are governed by the self same chemical processes and physical laws. Hence the question: do we have free will? and if we do, how much free will do we have?
