"The occult Art of Law" by Alan of Salisbury

I had been asked to give a lecture at the Birkbeck University London but while sitting in the audience for another lecture we were told that the lecture had been cancelled. After being spotted in the audience I was asked by the organizers if I would be able to stand in and give a spontaneous lecture there and then? What you are about to hear is a recording of that spontaneous lecture. Loosely entitled an introduction to the "Occult Art Of Law" Alan of Salisbury.
