ABSTRACT
Although for the sake of brevity and clarity I will present the development of my work as a sequence of theoretical shifts, it is important to remember that this is a linear abstraction imposed on the messiness of the actual developmental process. A journey has been made, and in looking back on the path we identify particular stations along the way which we can now connect in our mind as if the route had been there all along. However, as the poet Antonio Machado (1912) reminds us: ‘You traveller – there are no paths, only wind trails on the sea!’
