How We Know That Shakespeare Wrote Shakespeare: The Historical Facts
You should probably black-list that website because it's totally freaking useless and those moron have no understanding of anything.
Conclusion
How do we know that Shakespeare wrote Shakespeare? We know because the historical record tells us so, strongly and unequivocally.
Yet they fail to provide a single shred of evidence.
The historical evidence demonstrates that one and the same man, William Shakespeare of Stratford-upon-Avon, was William Shakespeare the player, William Shakespeare the Globe-sharer, and William Shakespeare the author of the plays and poems that bear his name -- and no person of the Elizabethan and Jacobean eras ever doubted the attribution.
Lack of doubt is not evidence.
No Elizabethan ever suggested that Shakespeare's plays and poems were written by someone else, or that Shakespeare the player was not Shakespeare the author, or that Shakespeare the Globe-sharer was not Shakespeare of Stratford.
Suggestions are not evidence.
No contemporary of Shakespeare's ever suggested that the name used by the player, the Globe-sharer, or the author was a pseudonym; and none of the major alternative candidates -- not Francis Bacon, not the Earl of Oxford, not Christopher Marlowe -- had any connection with Shakespeare's acting company or with his friends and fellow actors.
Lack of suggestions or connections are not evidence.
Not only does your erroneous source fail to provide even one piece of evidence, they're entire view is 100% anachronistic.
Maybe if Shakespeare was writing in the last 30 years they're irrelevant claims might hold some weight but still not rise to the level of evidence.
Plus they lack moral and ethical integrity by addressing the real issue. In other words, they lied.
There's something called forensic document analysis. Everyone has a unique style of writing, the order of elements (nouns, verbs, adjectives and adverbs) and go to phrases and buzzwords in addition to unique phraseology.
Forensic document analysis is how the so-called Unabomber was identified and many other criminals as well as verifying the authenticity of other works over history.
The two most well-known are the Hebrew and Greek texts. Jeremiah and Hilkiah had a thing for the phrase "to this day" which is how we know they committed pious fraud and forged Deuteronomy and then heavily emended, amended and redacted the first four books.
For example, X-Moses' real name was probably Amenmoses or Anmoses (meaning "emanated/emanating from Amen" or "emanated/emanating from An) and Jeremiah and Hilkiah would have found the use of an Egyptian deity to be totally offensive and so they just struck it from the texts leaving "Moses" ("emanated/emanating from").
It's also how we know the Hebrew works existed as 3 separate texts written by 3 different people and then edited over the centuries by editors and we can identify the editors because of their writing style and phraseology and then those 3 texts were combined into one and we know one person had a hand in that because of their phraseology.
Well, actually four separate texts because the Abrahamic text was a separate text.
Some of Shakespeare's plays are questionable. There's a couple of plays about kings that Shakespeare did not write but he was a co-author and they were published under his name.
Something your anachronistic source doesn't understand is that someone read a play, it sounded a lot like Shakespeare and so it was attributed to Shakespeare. That is not a forgery but it is a misattribution.
A couple of others like
Lord Cromwell are clearly not Shakespeare. It isn't his style and isn't his phraseology and not his go to buzzwords. That's either a misattribution or someone published it under Shakespeare's name.
Your anachronistic source doesn't understand that they didn't have driver's licenses and they didn't have TV so if some guy came into your printing shop and said
"I'm William Shakespeare and I want you to print this up" you wouldn't question it at all.
