Acknowledgements
We wish to thank all the participants in the workshop for making it such a fruitful event. Steve Fuller contributed the most to organize it and he was the first to suggest the possibility of publishing this special issue. The authors cooperated in a way that deserves praise. Miranda del Corral kindly helped us in the preparation of the manuscripts for publication. Jeremy Howick and Julian Reiss provided useful comments. We should acknowledge the constant supporting contribution of the Urrutia Elejalde Foundation, and the funding received from the CSIC (Instituto de Filosofía), FECYT (Fundación Española para la Ciencia y la Tecnología) and the Spanish Ministry of Education (grant SEJ2004–20076E). Another research grant on the emergence of scientific norms (HUM2005–01686/FISO) supported the authors’ research.
