Call The Fifth AISB Symposium on Computing and Philosophy was held at the joint AISB/IACAP World Congress 2012 in Birmingham from 2nd to 6th July 2012 (http://events.cs.bham.ac.uk/turing12/in\\... on the topic of Computing, Philosophy and the Question of Bio-Machine Hybrids. The Congress was co-organised by AISB (http://www.aisb.org.uk) and IACAP (http://www.iacap.org), and was held in honour of Alan Turing, as part of the Centenary celebrations of his life and work. Following this symposium, a special issue of Springer's Philosophy & Technology journal (http://www.springer.com/13347) is now being planned. We invite all those working in these (typically interdisciplinary) areas to participate in the project by contributing a paper for consideration to the special issue. In this call we particularly encourage submissions that address one or more of the themes discussed above. Authors who presented a paper at this conference are invited to submit an original, recently revised, version of that paper, while other interested authors are invited to submit original papers related to the topics mentioned below. All submissions will be double peer-reviewed according to usual standards. Submitted papers must not have
