Question: Which English philosopher did Henry Seymour believe authored plays under the pseudonym of William Shakespeare?

full_context: Document 1: Sonnet 28: Sonnet 28 is one of 154 sonnets written by the English playwright and poet William Shakespeare, it was first published in 1609. The sonnet is a part of the Fair Youth sequence, in which the poet expresses his love towards a young man — usually referred to as "the young man" or the "friend". Shakespeare's use of "friend" means more than just of a sexual nature, it highlights the Renaissance ideal of male fidelity and equality. From sonnets 18 to 126, Shakespeare writes about his relationship with the said young man. Although the identity of the young man is still unknown, Henry Wriothesley and William Herbert, 3rd Earl of Pembroke, are the two leading contenders.
Document 2: Henry Seymour (secularist): Henry Albert Seymour (1861–1938) was a British secularist, individualist anarchist, gramophone innovator and survey author, and Baconian. He published the first English language anarchist periodical in Britain and is credited, in 1913, with introducing the Edison disc into the country.
Document 3: Sonnet 110: Sonnet 110 is one of 154 sonnets written by the English playwright and poet William Shakespeare. Sonnet 110 was published along with the other sonnets in the 1609 Quarto. The sonnet falls in place with the Fair Youth sequence of Shakespeare's sonnets, in which the poet expresses his love towards a young man. The mystery of the young man is still unknown today. However, there are many different theories by various scholars of who this young man may be. There has been much debate whether or not this sonnet was written about Shakespeare's disdain with the stage and actors. Whereas others have interpreted sonnet 110 as the poet confessing his love to a young man.
Document 4: Lord Henry Seymour (politician): Lord Henry Seymour (15 December 1746 – 5 February 1830) was a British politician, the second son of Francis Seymour-Conway, 1st Marquess of Hertford. He was known as Hon. Henry Seymour-Conway until 1793, when his father was created a marquess; he then became Lord Henry Seymour-Conway, but dropped the surname of Conway after his father's death in 1794.
Document 5: William Shakespeare: William Shakespeare ( ; 26 April 1564 (baptised) – 23 April 1616) was an English poet, playwright, and actor, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet, and the "Bard of Avon". His extant works, including collaborations, consist of approximately 38 plays, 154 sonnets, two long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright.
Document 6: John Bacon (judge): Bacon is first mentioned as acting in the capacity of attorney to Queen Eleanor in 1278-9, and is described in certain indentures of the exchequer, dated 1288, as 'clericus Regis' and 'custos rotulorum et brevium de Banco' and 'Regis thesauriarius et camerarius,' his business being to keep a list of the cases argued in the common pleas, and to transmit records thereof, and also 'pedes chirographorum,' i.e. memoranda of fines levied throughout the country, to the treasurers and chamberlains of the exchequer, of the receipt of which the indentures already mentioned were acknowledgments. The 'chirographa,' or fines in question, were fictitious suits, by means of which it was the custom to bar entails and convey the landed property of married women. Bacon seems to have held this post as late as 1309. In 1291 he was entrusted with the charge of Leeds Castle in Kent (a royal residence). In 1313 he was appointed to a justiceship of the common pleas, and in the same year we read of his being retained in London to advise the king upon some important matters. In 1314 he was made one of the commissioners of oyer and terminer for the counties of Norfolk and Suffolk, to try certain assessors and collectors of the revenue charged with breach of trust. In 1315 William de Beresford, the chief justice of the common pleas, being suddenly summoned to the king, the business of the court devolved upon Thrikingham and Bacon exclusively. We may conjecture that it was not very promptly or efficiently despatched, for it was but a short time since he had been enjoined to pay a more diligent attention to duty. In 1317 he was summoned with the rest of the judges to parliament at Lincoln, but the invasion of the Scots in that year caused the postponement of the parliament sine die. In 1320 he was placed on a commission to try certain persons charged with debasing and counterfeiting the coinage in the counties of Essex, Norfolk, and Suffolk, and in 1321 upon another directed to inquire into offences committed by sheriffs and other legal functionaries under colour of their official duties in the counties of Norfolk, Suffolk, Cambridge, and Huntingdon. He appears to have died in this year, Stonore being appointed justice of the common pleas in his place. He had landed property in Reston, Hemingston, Cleydon, and Akenham, places all of them in the county of Suffolk, and also in Essex, and at Shouldham in Norfolk.
Document 7: Anonymous (film): Anonymous is a 2011 political thriller film directed by Roland Emmerich and written by John Orloff. The film is a version of the life of Edward de Vere, 17th Earl of Oxford, an Elizabethan courtier, playwright, poet and patron of the arts, and suggests he was the actual author of William Shakespeare's plays. It stars Rhys Ifans as de Vere and Vanessa Redgrave as Queen Elizabeth I of England.
Document 8: Baconian theory of Shakespeare authorship: The Baconian theory of Shakespearean authorship holds that Sir Francis Bacon, philosopher, essayist and scientist, wrote the plays which were publicly attributed to William Shakespeare. Various explanations are offered for this alleged subterfuge, most commonly that Bacon's rise to high office might have been hindered were it to become known that he wrote plays for the public stage. Thus the plays were credited to Shakespeare, who was merely a front to shield the identity of Bacon.
Document 9: Henry Bool: Henry Bool (1846–1922) was an American individualist anarchist. Bool was born in England and in 1872 emigrated to Ithaca, NY, (arriving in New York NY 15 May 1872) where he lived as a businessman for 30 years before returning to England, where he died in Montacute, Somerset, in 1922. While in the U.S. Bool began reading and adopting the philosophy of the American individualist anarchists as his own; he said, "I am a believer in the doctrines of the individualistic school of Anarchists, to which Garrison, Emerson, Proudhon, Thoreau, Spooner, Andrews, Warren and Tucker belong." He is most noted for opposing propaganda by the deed and communist anarchism.
Document 10: Henry Mayhew: Henry Mayhew (25 November 1812 – 25 July 1887) was an English social researcher, journalist, playwright and advocate of reform. He was one of the co-founders of the satirical and humorous magazine "Punch" in 1841, and was the magazine's joint-editor, with Mark Lemon, in its early days. He is also known for his work as a social researcher, publishing an extensive series of newspaper articles in the "Morning Chronicle" that was later compiled into the book series "London Labour and the London Poor" (1851), a groundbreaking and influential survey of the city's poor.
Document 11: Ben Jonson: Benjamin "Ben" Jonson (c. 11 June 1572 – 6 August 1637) was an English playwright, poet, actor, and literary critic, whose artistry exerted a lasting impact upon English poetry and stage comedy. He popularised the comedy of humours. He is best known for the satirical plays "Every Man in His Humour" (1598), "Volpone, or The Fox" (c. 1606), "The Alchemist" (1610) and "Bartholomew Fair" (1614) and for his lyric poetry; he is generally regarded as the second most important English playwright during the reign of James I after William Shakespeare.
Document 12: Josiah Warren: Josiah Warren ( ; 1798 – April 14, 1874) was an individualist anarchist, inventor, musician, and author in the United States. He is regarded by some as the first American anarchist, (though he never used the term himself) and the four-page weekly paper he edited during 1833, "The Peaceful Revolutionist", the first anarchist periodical published, an enterprise for which he built his own printing press, cast his own type, and made his own printing plates.
Document 13: Shakespeare's life: William Shakespeare was an actor, playwright, poet, and theatre entrepreneur in London during the late Elizabethan and early Jacobean eras. He was baptised on 26 April 1564 in Stratford-upon-Avon in Warwickshire, England, in the Holy Trinity Church. At age 18 he married Anne Hathaway with whom he had three children. He died in his home town of Stratford on 23 April 1616 at the age of 52. Though more is known about Shakespeare's life than those of most other Elizabethan and Jacobean writers, few personal biographical facts survive about him, which is unsurprising in the light of his social status as a commoner, the low esteem in which his profession was held, and the general lack of interest of the time in the personal lives of writers. Information about his life derives from public instead of private documents: vital records, real estate and tax records, lawsuits, records of payments, and references to Shakespeare and his works in printed and hand-written texts. Nevertheless, hundreds of biographies have been written and more continue to be, most of which rely on inferences and the historical context of the 70 or so hard facts recorded about Shakespeare the man, a technique that sometimes leads to embellishment or unwarranted interpretation of the documented record.
Document 14: Herbert Ingram: Herbert Ingram (27 May 1811 – 8 September 1860) was a British journalist and politician. He is considered the father of pictorial journalism through his founding of "The Illustrated London News", the first illustrated magazine. He was a Liberal politician who favoured social reform and represented Boston for four years until his early death in a shipping accident.
Document 15: Henry Seymour (16th-century MP): Sir Henry Seymour (c. 1503 – 5 April 1578) was an English landowner and MP, the brother of Jane Seymour, queen consort of Henry VIII, and consequently uncle to Edward VI. He was created a Knight of the Bath after his nephew's coronation.
