A Rose by Any Other Name...

October 22, 2015

One riddle often heard in my childhood was, "Who's buried in Grant's tomb?" Although the remains of Ulysses S. Grant (1822-1885), the 18th President of the United States, and his wife, Julia Grant (1826-1902) are in this Manhattan monument, they're not buried there; rather, they are entombed.

What sounds like a nearly equivalent riddle, "Who wrote the works of William Shakespeare," is a question that's been argued for nearly two hundred years. Some claim that Shakespeare was the literary equivalent of the mathematician, Nicolas Bourbaki. Just as Bourbaki was the pseudonym of a group of 20th century mathematicians, some have claimed that Shakespeare was the pseudonym for one or more authors who chose to remain anonymous.

The Cobbe portrait is similar in likeness to the Droeshout engraving of Shakespeare that appears in the First Folio of 1623, albeit with a little more hair.

The circumstantial evidence for the claim that Shakespeare did not write Shakespeare is that the historical Shakespeare doesn't seem qualified to have written literature at such a grand scale. Such authorship more likely rests with an educated nobleman or courtier. Although Shakespeare's authorship of his literary corpus was never doubted in his lifetime, or for centuries thereafter, many other people have been proposed as the real Shakespeare. Prominent in this list are Christopher Marlowe (1564-1593) and Sir Francis Bacon (1561-1626).

Mark Twain, as revealed in his 1909 book, Is Shakespeare Dead?, agreed with the theory that Bacon was the author of Shakespeare's works. Along the lines of where have we read this story before, people have searched for ciphers offering clues of Bacon's authorship of Shakespeare's works in the works of both Bacon and Shakespeare.

Bacon was an early proponent of what is now called the
scientific method, although his techniques were more empirical than analytical. That's why he's called the father of empiricism, and not the father of the scientific method.

U.S. Congressman, Ignatius L. Donnelly, whom we encountered in connection with the Atlantis myth in a previous article (Science and the Atlantis Myth, May 18, 2012), added fuel to the fire with his book, The Great Cryptogram.[1] In this book, Donnelly presents arguments that Bacon inserted ciphers that expose his authorship into the Shakespeare texts.

The prominent 20th century cryptographer, William F. Friedman, examined the question of such secret codes, and he found that the idea had no merit.[2] Friedman even used the same techniques to "prove" that U.S. President, Theodore Roosevelt, was the actual author of Shakespeare's works.

Although the cipher issue is apparently dead, the computer age has brought us new tools in the examination of the authorship of Shakespeare's works. There's no lack of source material, since there are 36 plays in the First Folio of 1623. The primary tool is stylistic analysis, especially writer invariant text. Such analysis indicates Marlowe's hand in at least some portions of Henry VI, Part 1 and Part 2.[3]

There's a converse problem of Shakespeare authorship; namely, which works not in the original folios might actually have been written by him. A prime example is the 1727 play, Double Falsehood (a.k.a., Double Falshood, or The Distrest Lovers). This is a play written by the 18th century English playwright, Lewis Theobald (1688-1744), but acknowledged by him as being based on three unnamed Shakespeare manuscripts. These original manuscripts were lost, probably in a library fire. All this has engendered another controversy that this was an original work by Theobald, who tried to generate interest in his play by claiming it to be an adaptation of a work by Shakespeare.

There is evidence that this play, inspired by the character, Cardenio, in Cervantes' Don Quixote, is actually based on a lost play, Cardenio, by William Shakespeare and John Fletcher. Such a play was registered at the Stationers' Register, September 9, 1653. This presents the question of how much of Double Falsehood, if any, is Shakespeare's own, independent of Theobald and Fletcher.

Psychologists at the University of Texas at Austin have done an analysis of Double Falsehood, and they found strong statistical and psychological evidence of Shakespeare and Fletcher's co-authorship. To do this, they developed a psychological "signature" for each possible author, and their analysis indicates that the play was not a forgery by Theobald. Their research is reported in Psychological Science.[4-5]

Rather than using the word counts and linguistic regularities of stylistic analysis, the study compares authors' psychological profiles.[5] Says graduate student, Ryan Boyd, who co-authored the study with UT-Austin professor, James Pennebaker,
"Research in psychology has shown that some of the core features of who a person is at their deepest level can be revealed based on how they use Language. With our new study, we show that you can actually take a lot of this information and put it all together at once to understand an author like Shakespeare rather deeply."[5]

Boyd and Pennebaker analyzed 33 plays by Shakespeare, 12 by Theobald, and 9 by John Fletcher. Extraneous information, such as publication information, was removed, and software made possible an analysis of such things as the use of function words (pronouns, articles, and prepositions) and words related to categories such as emotions, religion, and sensory perception. The heavy use of nouns, articles, and prepositions indicates a formal way of thinking. People who use such words often tend to be emotionally distant, while people who use such words sparingly tend to live in the moment, and they are more social.[5] In such ways they created a thematic signature for each author.[5]

By every measure except one, Shakespeare was identified as the most probable author of Double Falsehood.[4-5] Shakespeare's hand is most apparent in the early part of the play, in the first three acts, while Shakespeare and Fletcher shared authorship of the fourth and fifth acts.[5] Theobald's influence was minor, as confirmed by the assessment that the play's authors were sociable, while Theobald was known to be rigid and abrasive.[5] Says Boyd,
"Honestly, I was surprised to see such a strong signal for Shakespeare showing through in the results... Going into the research without any real background knowledge, I had just kind of assumed that it was going to be a pretty cut and dry case of a fake Shakespeare play, which would have been really interesting in and of itself... We don't need a time machine and a survey form to figure out what type of person Shakespeare was -- we can determine that very accurately just based on how he wrote using methods that are objective and easy to do."[5]
