Francis Bacon, 1st Viscount St Albans (22 January 1561 – 9 April 1626) was an English philosopher, statesman, scientist, lawyer, jurist, author and pioneer of the scientific method. He served both as Attorney General and Lord Chancellor of England. Although his political career ended in disgrace, he remained extremely influential through his works, especially as philosophical advocate and practitioner of the scientific method during the scientific revolution.

Bacon has been called the father of empiricism. His works established and popularized inductive methodologies for scientific inquiry, often called the Baconian method, or simply the scientific method. His demand for a planned procedure of investigating all things natural marked a new turn in the rhetorical and theoretical framework for science, much of which still surrounds conceptions of proper methodology today. His dedication probably led to his death, bringing him into a rare historical group of scientists who were killed by their own experiments.

Bacon was knighted in 1603, and created both the Baron Verulam in 1618, and the Viscount St Alban in 1621; as he died without heirs both peerages became extinct upon his death. He famously died of pneumonia contracted while studying the effects of freezing on the preservation of meat.

Bacon was born on 22 January 1561 at York House near the Strand in London, the son of Sir Nicholas Bacon by his second wife Anne (Cooke) Bacon, the daughter of noted humanist Anthony Cooke. His mother's sister was married to William Cecil, 1st Baron Burghley, making Burghley Francis Bacon's uncle. Biographers believe that Bacon was educated at home in his early years owing to poor health (which plagued him throughout his life), receiving tuition from John Walsall, a graduate of Oxford with a strong leaning towards Puritanism. He entered Trinity College, Cambridge, on 5 April 1573 at the age of twelve, living for three years there together with his older brother Anthony under the personal tutelage of Dr John Whitgift, future Archbishop of Canterbury. Bacon's education was conducted largely in Latin and followed the medieval curriculum. He was also educated at the University of Poitiers. It was at Cambridge that he first met Queen Elizabeth, who was impressed by his precocious intellect, and was accustomed to calling him "the young Lord Keeper".

His studies brought him to the belief that the methods and results of science as then practiced were erroneous. His reverence for Aristotle conflicted with his loathing of Aristotelian philosophy, which seemed to him barren, disputatious, and wrong in its objectives.

On 27 June 1576, he and Anthony entered de societate magistrorum at Gray's Inn. A few months later, Francis went abroad with Sir Amias Paulet, the English ambassador at Paris, while Anthony continued his studies at home. The state of government and society in France under Henry III afforded him valuable political instruction. For the next three years he visited Blois, Poitiers, Tours, Italy and Spain. During his travels, Bacon studied language, statecraft and civil law while performing routine diplomatic tasks. On at least one occasion he delivered diplomatic letters to England for Walsingham, Burghley and Leicester, as well as for the queen.

The sudden death of his father in February 1579 prompted Bacon to return to England. Sir Nicholas had laid up a considerable sum of money to purchase an estate for his youngest son, but he died before doing so, and Francis was left with only a fifth of that money. Having borrowed money, Bacon got into debt. To support himself, he took up his residence in law at Gray's Inn in 1579.

Bacon's threefold goals were to uncover truth, to serve his country and to serve his church. He sought to further these ends by seeking a prestigious post. In 1580, through his uncle, Lord Burghley, he applied for a post at court, which might enable him to pursue a life of learning. His application failed. For two years he worked quietly at Gray's Inn, until he was admitted as an outer barrister in 1582.

His parliamentary career began when he was elected MP for Bossiney, Devon, in a 1581 by-election. In 1584, he took his seat in parliament for Melcombe in Dorset, and subsequently for Taunton (1586). At this time, he began to write on the condition of parties in the church, as well as on the topic of philosophical reform in the lost tract, Temporis Partus Maximus. Yet, he failed to gain a position he thought would lead him to success. He showed signs of sympathy to Puritanism, attending the sermons of the Puritan chaplain of Gray's Inn and accompanying his mother to the Temple chapel to hear Walter Travers. This led to the publication of his earliest surviving tract, which criticized the English church's suppression of the Puritan clergy. In the Parliament of 1586, he openly urged execution for Mary, Queen of Scots.

About this time, he again approached his powerful uncle for help; this move was followed by his rapid progress at the bar. He became Bencher in 1586, and he was elected a reader in 1587, delivering his first set of lectures in Lent the following year. In 1589, he received the valuable appointment of reversion to the Clerkship of the Star Chamber, although he did not formally take office until 1608 – a post which was worth £16,000 a year.

In 1588 he was returned as MP for Liverpool and then for Middlesex in 1593. He later sat three times for Ipswich (1597, 1601, 1604) and once for Cambridge University (1614).

Bacon soon became acquainted with Robert Devereux, 2nd Earl of Essex, Queen Elizabeth's favorite. By 1591, he acted as the earl's confidential adviser.

In 1592, he was commissioned to write a tract in response to the Jesuit Robert Parson's anti - government polemic, which he entitled Certain observations made upon a libel, identifying England with the ideals of democratic Athens against the belligerence of Spain.

Bacon took his third parliamentary seat for Middlesex when in February 1593 Elizabeth summoned Parliament to investigate a Roman Catholic plot against her. Bacon's opposition to a bill that would levy triple subsidies in half the usual time offended many people. Opponents accused him of seeking popularity. For a time, the royal court excluded him.

When the Attorney Generalship fell vacant in 1594, Lord Essex's influence was not enough to secure Bacon that office. Likewise, Bacon failed to secure the lesser office of Solicitor General in 1595. To console him for these disappointments, Essex presented him with a property at Twickenham, which he sold subsequently for £1,800.

In 1596, Bacon became Queen's Counsel, but missed the appointment of Master of the Rolls. During the next few years, his financial situation remained bad. His friends could find no public office for him, and a scheme for retrieving his position by a marriage with the wealthy and young widow Lady Elizabeth Hatton failed after she broke off their relationship upon accepting marriage to a wealthier man. In 1598 Bacon was arrested for debt. Afterwards however, his standing in the Queen's eyes improved. Gradually, Bacon earned the standing of one of the learned counsels, though he had no commission or warrant and received no salary. His relationship with the Queen further improved when he severed ties with Robert Devereux, 2nd Earl of Essex, a shrewd move because Essex was executed for treason in 1601.

With others, Bacon was appointed to investigate the charges against Essex, his former friend and benefactor. A number of Essex's followers confessed that Essex had planned a rebellion against the Queen. Bacon was subsequently a part of the legal team headed by Attorney General Sir Edward Coke at Essex's treason trial. After the execution, the Queen ordered Bacon to write the official government account of the trial, which was later published as A DECLARATION of the Practices and Treasons attempted and committed by Robert late Earle of Essex and his Complices, against her Majestie and her Kingdoms ... after Bacon's first draft was heavily edited by the Queen and her ministers.

The succession of James I brought Bacon into greater favor. He was knighted in 1603. In another shrewd move, Bacon wrote his Apologie in defense of his proceedings in the case of Essex, as Essex had favored James to succeed to the throne.

The following year, during the course of the uneventful first parliament session, Bacon married Alice Barnham. In June 1607 he was at last rewarded with the office of Solicitor General. The following year, he began working as the Clerkship of the Star Chamber. In spite of a generous income, old debts still could not be paid. He sought further promotion and wealth by supporting King James and his arbitrary policies.

In 1610 the fourth session of James' first parliament met. Despite Bacon's advice to him, James and the Commons found themselves at odds over royal prerogatives and the king's embarrassing extravagance. The House was finally dissolved in February 1611. Throughout this period Bacon managed to stay in the favor of the king while retaining the confidence of the Commons.

In 1613, Bacon was finally appointed attorney general, after advising the king to shuffle judicial appointments. As attorney general, Bacon prosecuted Somerset in 1616. The so-called "Prince's Parliament" of April 1614 objected to Bacon's presence in the seat for Cambridge and to the various royal plans which Bacon had supported. Although he was allowed to stay, parliament passed a law that forbade the attorney general to sit in parliament. His influence over the king had evidently inspired resentment or apprehension in many of his peers. Bacon, however, continued to receive the King's favor, which led to his appointment in March 1617 as the temporary Regent of England (for a period of a month), and in 1618 as Lord Chancellor. On 12 July 1618 the king created Bacon Baron Verulam of Verulam or, as the new peer styled himself, Francis, Lord Verulam.

Bacon continued to use his influence with the king to mediate between the throne and Parliament and in this capacity he was further elevated, as Viscount St Alban, on 27 January 1621.

Bacon's public career ended in disgrace in 1621. After he fell into debt, a Parliamentary Committee on the administration of the law charged him with twenty - three separate counts of corruption. To the lords, who sent a committee to enquire whether a confession was really his, he replied, "My lords, it is my act, my hand, and my heart; I beseech your lordships to be merciful to a broken reed." He was sentenced to a fine of £40,000 that was remitted by King James and committed to the Tower of London during the king's pleasure; his imprisonment lasted only a few days. More seriously, parliament declared Bacon incapable of holding future office or sitting in parliament. He narrowly escaped being deprived of his titles. Subsequently the disgraced viscount devoted himself to study and writing.

There seems little doubt that Bacon had accepted gifts from litigants, but this was an accepted custom of the time and not necessarily evidence of deeply corrupt behavior. While acknowledging that his conduct had been lax, he countered that he had never allowed gifts to influence his judgement and, indeed, he had on occasion given a verdict against those who had paid him. The true reason for his acknowledgement of guilt is the subject of debate, but it may have been prompted by his poor state of health, or by a view that through his fame and the greatness of his office he would be spared harsh punishment. He may even have been blackmailed, with a threat to charge him with sodomy, into confession.

When he was 36, Bacon engaged in the courtship of Elizabeth Hatton, a young widow of 20. Reportedly, she broke off their relationship upon accepting marriage to a wealthier man — Edward Coke. Years later, Bacon still wrote of his regret that the marriage to Hatton had not taken place.

At the age of forty - five, Bacon married Alice Barnham, the fourteen year old daughter of a well connected London alderman and MP. Bacon wrote two sonnets proclaiming his love for Alice. The first was written during his courtship and the second on his wedding day, 10 May 1606. When Bacon was appointed Lord Chancellor, "by special Warrant of the King", Lady Bacon was given precedence over all other Court ladies.

Reports of increasing friction in his marriage to Alice appeared, with speculation that some of this may have been due to financial resources not being as readily available to her as she was accustomed to having in the past. Alice was reportedly interested in fame and fortune, and when reserves of money were no longer available, there were complaints about where all the money was going. Alice Chambers Bunten wrote in her Life of Alice Barnham that, upon their descent into debt, she actually went on trips to ask for financial favors and assistance from their circle of friends. Bacon disinherited her upon discovering her secret romantic relationship with John Underhill. He rewrote his will, which had previously been very generous to her (leaving her lands, goods, and income), revoking it all.

Though the well connected antiquary John Aubrey noted among his private memoranda concerning Bacon, "He was a Pederast. His Ganimeds and Favourites tooke Bribes", biographers continue to debate about Bacon's sexual inclinations and the precise nature of his personal relationships. Several authors believe that despite his marriage Bacon was primarily attracted to the same sex. Professor Forker for example has explored the "historically documentable sexual preferences" of both King James and Bacon – and concluded they were all oriented to "masculine love", a contemporary term that "seems to have been used exclusively to refer to the sexual preference of men for members of their own gender." The Jacobean antiquarian, Sir Simonds D'Ewes implied there had been a question of bringing him to trial for buggery. This conclusion has been disputed by others, who consider the sources to be more open to interpretation.

On 9 April 1626 Bacon died of pneumonia while at Arundel mansion at Highgate outside London. An influential account of the circumstances of his death was given by John Aubrey's Brief Lives. Aubrey has been criticized for his evident credulousness in this and other works; on the other hand, he knew Thomas Hobbes, Bacon's fellow philosopher and friend. Aubrey's vivid account, which portrays Bacon as a martyr to experimental scientific method, had him journeying to Highgate through the snow with the King's physician when he is suddenly inspired by the possibility of using the snow to preserve meat: "They were resolved they would try the experiment presently. They alighted out of the coach and went into a poor woman's house at the bottom of Highgate hill, and bought a fowl, and made the woman exenterate it".

After stuffing the fowl with snow, Bacon contracted a fatal case of pneumonia. Some people, including Aubrey, consider these two contiguous, possibly coincidental events as related and causative of his death: "The Snow so chilled him that he immediately fell so extremely ill, that he could not return to his Lodging ... but went to the Earle of Arundel's house at Highgate, where they put him into ... a damp bed that had not been layn - in ... which gave him such a cold that in 2 or 3 days as I remember Mr Hobbes told me, he died of Suffocation."

Being unwittingly on his deathbed, the philosopher wrote his last letter to his absent host and friend Lord Arundel:

My very good Lord, — I was likely to have had the fortune of Caius Plinius the elder, who lost his life by trying an experiment about the burning of Mount Vesuvius; for I was also desirous to try an experiment or two touching the conservation and induration of bodies. As for the experiment itself, it succeeded excellently well; but in the journey between London and Highgate, I was taken with such a fit of casting as I know not whether it were the Stone, or some surfeit or cold, or indeed a touch of them all three. But when I came to your Lordship's House, I was not able to go back, and therefore was forced to take up my lodging here, where your housekeeper is very careful and diligent about me, which I assure myself your Lordship will not only pardon towards him, but think the better of him for it. For indeed your Lordship's House was happy to me, and I kiss your noble hands for the welcome which I am sure you give me to it. I know how unfit it is for me to write with any other hand than mine own, but by my troth my fingers are so disjointed with sickness that I cannot steadily hold a pen."

Another account appears in a biography by William Rawley, Bacon's personal secretary and chaplain:

He died on the ninth day of April in the year 1626, in the early morning of the day then celebrated for our Saviour's resurrection, in the sixty - sixth year of his age, at the Earl of Arundel's house in Highgate, near London, to which place he casually repaired about a week before; God so ordaining that he should die there of a gentle fever, accidentally accompanied with a great cold, whereby the defluxion of rheum fell so plentifully upon his breast, that he died by suffocation.

At his funeral, over thirty great minds collected together their eulogies of him, which was then later published in Latin.

He left personal assets of about £7,000 and lands that realized £6,000 when sold. His debts amounted to more than £23,000, equivalent to more than £3m at current value.

Francis Bacon is the father of the scientific method, which is fundamental to natural philosophy. In his magnum opus, Novum Organum, or "new instrument", Francis Bacon argued that although philosophy at the time mainly used deductive syllogisms to interpret nature, mainly owing to Aristotle's logic (or Organon), the philosopher should instead proceed through inductive reasoning from fact to axiom to physical law. Before beginning this induction, the enquirer is to free his or her mind from certain false notions or tendencies which distort the truth. These are called "Idols" (idola), and are of four kinds:

• "Idols of the Tribe" (idola tribus), which are common to the race;
• "Idols of the Den" (idola specus), which are peculiar to the individual;
• "Idols of the Marketplace" (idola fori), coming from the misuse of language; and
• "Idols of the Theatre" (idola theatri), which result from an abuse of authority.

The end of induction is the discovery of forms, the ways in which natural phenomena occur, the causes from which they proceed.

Bacon explicated his somewhat fragmentary ethical system – derived through use of his methods – in the seventh and eighth books of his De augmentis scientiarum (1623) – where he distinguished between duty to the community (an ethical matter) and duty to God (a religious matter). Bacon claimed that:

• Any moral action is the action of the human will, which is governed by belief and spurred on by the passions;
• Good habit is what aids men in directing their will toward the good; and
• No universal rules can be made, as both situations and men's characters differ.

Regarding faith, in De augmentis, he wrote that "the more discordant, therefore, and incredible, the divine mystery is, the more honor is shown to God in believing it, and the nobler is the victory of faith." He wrote in "The Essays: Of Atheism" that "a little philosophy inclineth man’s mind to atheism; but depth in philosophy bringeth men’s minds about to religion." Meanwhile in the very next essay called: "Of Superstition" Bacon remarks - "Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation: all which may be guides to an outward moral virtue... but superstition dismounts all these and erecteth an absolute monarchy in the minds of men: therefore atheism never did perturb states; for it makes men wary of themeselves... and we see the times inclined to atheism (as the time of Augustus Caesar) were civil times; but superstition hath been the confusion of many states, and bringeth in a new 'primum mobile.' that ravisheth all the spheres of government." However, Bacon did maintain his own Christian beliefs, of which he differentiated from "superstition". Bacon notes that “It is better to have no opinion of God at all, than such an opinion as is unworthy of him: for the one is unbelief the other is contumely; and certainly superstition is the reproach of the Deity.” Yet even more than this, Bacon's views of God are in accordance with popular protestant theology, as he writes that “They that deny a God destroy man's nobility; for certainly man is of kin to the beasts in his body; and, if he be not of kin to God by his spirit, he is a base and ignoble creature.”

Nevertheless, Bacon contrasted the new approach of the development of science with that of the Middle Ages:

"Men have sought to make a world from their own conception and to draw from their own minds all the material which they employed, but if, instead of doing so, they had consulted experience and observation, they would have the facts and not opinions to reason about, and might have ultimately arrived at the knowledge of the laws which govern the material world."

Since Bacon's ideal was widespread revolution of the common method of scientific inquiry, there had to be some way by which his method could become widespread. His solution was to lobby the state to make natural philosophy a matter of greater importance – not only to fund it, but also to regulate it. While in office under Queen Elizabeth, he even advocated for the employment of a Minister for Science and Technology; a position which was never realized. Later under King James, Bacon wrote in The Advancement of Learning: "The King should take order for the collecting and perfecting of a Natural and Experimental History, true and severe (unencumbered with literature and book learning), such as philosophy may be built upon, so that philosophy and the sciences may no longer float in air, but rest on the solid foundation of experience of every kind."

While Bacon was a strong advocate for state involvement in scientific inquiry, he also felt that his general method should be applied directly to the functioning of the state as well. For Bacon, matters of policy were inseparable from philosophy and science. Bacon recognized the repetitive nature of history, and sought to correct it by making the future direction of government more rational. In order to make future civil history more linear and achieve real progress, he felt that methods of the past and experiences of the present should be examined together in order to determine the best ways by which to go about civil discourse. Bacon began one particular address to the house of Commons with a reference to the book of Jeremiah: "Stand in the ancient ways, but look also into present experience in order to see whether in the light of this experience ancient ways are right. If they are found to be so, walk in them." In short, he wanted his method of progress building on progress in natural philosophy to be integrated into England's political theory.

Bacon's works include his Essays, as well as the Colours of Good and Evil and the Meditationes Sacrae, all published in 1597. (His famous aphorism, "knowledge is power", is found in the Meditations.) He published Of the Proficience and Advancement of Learning, Divine and Human in 1605. Bacon also wrote In felicem memoriam Elizabethae, a eulogy for the queen written in 1609; and various philosophical works which constitute the fragmentary and incomplete Instauratio magna (Great Renewal), the most important part of which is the Novum Organum (New Instrument, published 1620); in this work he cites three world changing inventions:

"Printing, gunpowder and the compass: These three have changed the whole face and state of things throughout the world; the first in literature, the second in warfare, the third in navigation; whence have followed innumerable changes, in so much that no empire, no sect, no star seems to have exerted greater power and influence in human affairs than these mechanical discoveries."

Peter Linebaugh and Marcus Rediker have argued that Bacon was not as idealistic as his utopian works suggest, rather that he was what might today be considered an advocate of genocidal eugenics. A year prior to the release of New Atlantis, Bacon published an essay that reveals a version of himself not often seen in history. This essay, a lesser known work entitled, An Advertisement Touching a Holy War, advocated the elimination of detrimental societal elements by the English and compared this to the endeavors of Hercules while establishing civilized society in ancient Greece. He saw the "extirpation and debellating of giants, monsters, and foreign tyrants, not only as lawful, but as meritorious, even divine honour..."

Laurence Lampert has interpreted Bacon's treatise An Advertisement Touching a Holy War as advocating "spiritual warfare against the spiritual rulers of European civilisation."

In 1623, Bacon expressed his aspirations and ideals in New Atlantis. Released in 1627, this was his creation of an ideal land where "generosity and enlightenment, dignity and splendor, piety and public spirit" were the commonly held qualities of the inhabitants of Bensalem. In this work, he portrayed a vision of the future of human discovery and knowledge. The plan and organization of his ideal college, "Salomon's House", envisioned the modern research university in both applied and pure science. There has been much speculation as to whether a real island society inspired Bacon's utopia. Scholars have suggested numerous countries, from Iceland to Japan; Dr. Nick Lambert highlighted the latter in The View Beyond.

The Novum Organum is a philosophical work by Francis Bacon published in 1620. The title is a reference to Aristotle's work Organon, which was his treatise on logic and syllogism. In Novum Organum, Bacon detailed a new system of logic he believed to be superior to the old ways of syllogism. In this work, we see the development of the Baconian method, consisting of procedures for isolating the formal cause of a phenomenon (heat, for example) through eliminative induction.

Bacon's ideas were influential in the 1630s and 1650s among scholars, in particular Sir Thomas Browne, who in his encyclopaedia Pseudodoxia Epidemica (1646 – 1672) frequently adheres to a Baconian approach to his scientific enquiries. During the Restoration, Bacon was commonly invoked as a guiding spirit of the Royal Society founded under Charles II in 1660. In the nineteenth century his emphasis on induction was revived and developed by William Whewell, among others.

Some scholars believe that Bacon's vision for a Utopian New World in North America was laid out in his novel New Atlantis, which depicts a mythical island, Bensalem, located somewhere between Peru and Japan. He envisioned a land where there would be greater rights for women, the abolition of slavery, elimination of debtors' prisons, separation of church and state, and freedom of religious and political expression. Francis Bacon played a leading role in creating the British colonies, especially in Virginia, the Carolinas, and Newfoundland in northeastern Canada. He has been connected to the mysterious Oak Island buried treasure. His government report on “The Virginia Colony” was submitted in 1609. In 1610 Bacon and his associates received a charter from the king to form the Tresurer and the Companye of Adventurers and planter of the Cittye of london and Bristoll for the Collonye or plantacon in Newfoundland and sent John Guy to found a colony there. In 1910 Newfoundland issued a postage stamp to commemorate Bacon's role in establishing the province. The stamp describes Bacon as, "the guiding spirit in Colonization Schemes in 1610." Thomas Jefferson, the third President of the United States wrote: "Bacon, Locke and Newton. I consider them as the three greatest men that have ever lived, without any exception, and as having laid the foundation of those superstructures which have been raised in the Physical and Moral sciences".

The Baconian theory of Shakespearean authorship, first proposed in the mid 19th century, contends that Sir Francis Bacon wrote the plays conventionally attributed to William Shakespeare, in opposition to the scholarly consensus that William Shakespeare of Stratford was the author.

Francis Bacon often gathered with the men at Gray's Inn to discuss politics and philosophy, and to try out various theatrical scenes that he admitted writing. Bacon's alleged connection to the Rosicrucians and the Freemasons has been widely discussed by authors and scholars in many books. However others, including Daphne du Maurier (in her biography of Bacon), have argued there is no substantive evidence to support claims of involvement with the Rosicrucians. Frances Yates does not make the claim that Bacon was a Rosicrucian, but presents evidence that he was nevertheless involved in some of the more closed intellectual movements of his day. She argues that Bacon's movement for the advancement of learning was closely connected with the German Rosicrucian movement, while Bacon's New Atlantis portrays a land ruled by Rosicrucians. He apparently saw his own movement for the advancement of learning to be in conformity with Rosicrucian ideals.

Francis Bacon's influence can also be seen on a variety of religious and spiritual authors, and on groups that have utilized his writings in their own belief systems.
