“Shakespeare” was obsessed with truth. In his works he used the word “truth” at least 309 times and “true” no less than 766 times, with “truer” and “truest” and “truths” about three dozen times – well over a thousand usages of those five word forms. Equally obsessed with truth was Edward de Vere, starting with his earldom motto VERO NIHIL VERIUS or Nothing Truer than Truth. So similar are “Shakespeare” and Oxford in this respect that “truth” is another reason to believe they were one and the same.

The similarity is not just in terms of quantity but also in regard to how “truth” is used by “Shakespeare” and by Oxford in writings under his own name. For example, in the Shakespearean plays the phrase “truth is truth” appears three times: King John (1.1); Love’s Labour’s Lost (4.1); and in Measure for Measure (5.1), when Isabella says: “It is not truer he is Angelo than this is all as true as it is strange: Nay, it is ten times true; for truth is truth to the end of reckoning.”
Oxford wrote to Robert Cecil on 7 May 1603, several weeks after the death of Queen Elizabeth and the accession of King James: “But I hope truth is subject to no prescription, for truth is truth though never so old, and time cannot make that false which was once true.”
In my view, Oxford wrote Shakespeare’s Sonnet 123 during the same period, just a few days before Elizabeth’s funeral on 28 April 1603, expressing the same theme: “NO! Time, thou shalt not boast that I do change … Thy registers and thee I both defy … For thy records, and what we see, doth lie … This I do vow, and this shall ever be: I will be true, despite thy scythe and thee.”
Given such a similarity between the words in Oxford’s letter and those of Shakespeare’s sonnet, how can we fail to consider that both might have been written by the same man? “Shakespeare” believed that even though the winners of political power struggles would write the history for future generations, the truth will eventually come out. Certainly that was his overall objective for the sonnet sequence. His intention was to create a “monument … which eyes not yet created shall o’er-read.” (Sonnet 81)
The Merchant of Venice (2.2): “Give me your blessing; truth will come to light; murder cannot be hid long; a man’s son may, but at length truth will out.”
The Rape of Lucrece (stanza 135): “Time’s glory is to calm contending kings, to unmask falsehood and bring truth to light.”
Oxford to Robert Cecil in January 1602, in eerily similar words: “But now time and truth have unmasked all difficulties.”
Sonnet 82: “Thou, truly fair, wert truly sympathized in true plain words by thy true-telling friend.”
In the Shakespeare play, Troilus echoes Oxford’s motto Nothing Truer than Truth:
True swains in love shall in the world to come
Approve their truths by Troilus: when their rhymes,
Full of protest, of oath and big compare,
Want similes, truth tired with iteration,
As true as steel, as plantage to the moon,
As sun to day, as turtle to her mate,
As iron to adamant, as earth to the center,
Yet, after all comparisons of truth,
As truth’s authentic author to be cited,
“As true as Troilus” shall crown up the verse,
And sanctify the numbers.
(Troilus and Cressida, 3.2, emphasis added)

“Truth , which only doth judge itself, teacheth that the inquiry of truth, which is the love-making or wooing of it, the knowledge of truth, which is the presence of it, and the belief of truth, which is the enjoying of it, is the sovereign good of human nature.” Francis Bacon
Well said, Sir Bacon.
