http://pebblepad.glos.ac.uk/blog.aspx?blogoid=5503 - hope it is useful. [It may be of interest to those studying A-level, ( As / A2) Religious Studies, Philosopy & Ethics - or for thier revision]

[Oh - posts about the skills needed to study philosophy and/or ethics are still very welcome on the post below...]
