Sorry to interrupt, but what is it about the nature of our species that is to so attracted to conspiracy theories? We can trace this as far back as Homer and plenty of modern examples as well.
If I had a crystal ball I think it may well show a 2416 Ox/Cam luminary frothing at the bung as he expounded on the impossibility of an illiterate uneducated Lennon seen as the co-author and author of his celebrated works. I took an interest in the claims of the Earl Of Oxford after the film Anonymous made its preposterous contribution in 2011. I was particularly interested in the fact that the denialists draw so much confidence from their claims to have discovered hidden ciphers in epitaphs and ancillary texts. The Oxfordian method of unwinding these hidden messages (they are never ciphers) involves little more than separating all the letters and making words out of them as if they were a Scrabble bag with two dozen blank tiles. Oxfordians tend to stop as soon as they have found what they want. I was able to go a bit further, whilst sticking rigidly to their 'method'. As a result, I can offer a few new ideas about Shakespeare's favourite books which not even Professor Jonathan Bate may not have considered.
If you're into conspirancy theories, read on.
