Thomas Hobbes

Thomas Hobbes of Malmesbury (5 April 1588 – 4 December 1679) was one of the most consequential philosophers of early modern Europe and one of the principal architects of modern political philosophy. His writings transformed the conceptual vocabulary of sovereignty, political obligation, natural right, social contract, representation, law, liberty, necessity, and the relationship between civil and ecclesiastical authority. At the same time, Hobbes developed an ambitious materialist and mechanistic philosophy of nature, mind, language, and human action, attempting to construct a unified system of knowledge founded upon bodies, motion, nominal definition, and demonstrative reasoning.

His intellectual career unfolded against the extraordinary political and scientific transformations of seventeenth-century Europe: the final decades of the Tudor monarchy, the Jacobean and Caroline periods, the English Civil Wars, the Commonwealth and Protectorate, the Restoration of Charles II, and the emergence of the new experimental science associated with figures such as Galileo, Mersenne, Gassendi, Descartes, Boyle, and the Royal Society. Hobbes's political philosophy was shaped by this world of instability, but his response was radically different from the classical and medieval traditions against which he reacted. Political order, for Hobbes, was not grounded in an Aristotelian conception of the naturally political human being or in a teleological hierarchy of natural ends. It arose from the rational necessity of securing peace among fundamentally vulnerable and competitive individuals.

His most famous works—The Elements of Law, Natural and Politic, De Cive, Leviathan, De Corpore, De Homine, Behemoth, and the writings on liberty and necessity—form a body of work whose importance extends far beyond political theory. Hobbes was simultaneously a philosopher, political theorist, translator, classicist, historian, rhetorician, mathematician, optical theorist, theologian, and polemicist. His complete philosophical system was conceived as a tripartite science of Body, Man, and Citizen, although the order of composition and publication ultimately differed radically from the original plan.

Birth, Family, and Education

Hobbes was born on 5 April 1588 at Westport, then a separate settlement immediately outside Malmesbury in Wiltshire. The traditional story, preserved in Hobbes's own autobiographical verse, connected his premature birth with the panic caused by the expected arrival of the Spanish Armada. He famously wrote that his mother gave birth to “twins at once, myself and fear.”

His father, Thomas Hobbes senior, was vicar of Charlton and Westport. He was not a major intellectual or ecclesiastical figure, and his career ended disastrously after a quarrel and physical altercation with another clergyman. He subsequently disappeared from the family's life. Hobbes and his siblings were therefore largely supported by his uncle Francis Hobbes, a prosperous Malmesbury glover and alderman.

Hobbes showed exceptional intellectual ability from childhood. He attended the school attached to the church at Westport, where he learned Latin and Greek at an unusually early age. The tradition that he translated Euripides' Medea into Latin verse during his adolescence is consistent with the extraordinary classical education that prepared him for Oxford.

In 1603 Hobbes entered Magdalen Hall, Oxford, where he studied within the scholastic curriculum then dominant in English universities. He graduated B.A. in 1608. The Aristotelian natural philosophy and scholastic logic taught at Oxford left a lasting negative impression upon him. Hobbes subsequently attacked the scholastic use of obscure terminology and abstract entities, arguing that philosophy should proceed through precise definitions and demonstrative reasoning rather than through verbal disputes concerning entities that could not be clearly conceived.

The Cavendish Connection

The decisive event of Hobbes's early adult life was his appointment in 1608 as tutor to William Cavendish, later second Earl of Devonshire. The Cavendish family became the central institutional and financial support of Hobbes's entire career.

His relationship with the Cavendishes lasted for more than seventy years. Hobbes served successively as tutor, secretary, intellectual adviser, and family associate. The connection gave him access to private libraries, aristocratic patrons, political networks, and the financial independence necessary for a life devoted primarily to scholarship.

His association with the Cavendish family also enabled repeated journeys to the Continent. These travels were crucial to the development of his philosophy because they brought him into direct contact with intellectual cultures considerably more dynamic than the scholastic environment he had known at Oxford.

The First Continental Tour and Humanist Scholarship

In 1610, Hobbes accompanied William Cavendish on his first major European tour, visiting France and Italy. The journey exposed him to continental humanism, classical scholarship, and the changing intellectual landscape of early seventeenth-century Europe.

During his early career Hobbes was not yet primarily a philosopher. He was deeply engaged with classical literature, rhetoric, and history. His intellectual interests included Thucydides, Tacitus, and other historians whose writings he interpreted in relation to questions of political order and civil conflict.

He also became associated with Francis Bacon. Hobbes worked within Bacon's intellectual circle and is traditionally described as having served as Bacon's amanuensis and translated some of Bacon's essays into Latin. Their relationship is important, but Hobbes should not simply be regarded as a disciple of Bacon. His mature philosophy departed sharply from Baconian empiricism by emphasizing deductive demonstration, nominal definition, and mechanical causation.

The Translation of Thucydides

Hobbes's first major printed publication was not a philosophical treatise but a translation of Thucydides.

The first edition appeared in London in 1629 under the title Eight Bookes of the Peloponnesian Warre written by Thucydides the sonne of Olorus. Interpreted with faith and diligence immediately out of the Greeke by Thomas Hobbes secretary to the late Earle of Deuonshire. It was printed for Henry Seile at the Eliot's Court Press.

The translation was reissued in 1634, and later during Hobbes's lifetime in further editions, including 1648 and 1676. The work is fundamental for understanding Hobbes's early political thought. His Thucydides is not merely a linguistic exercise. The Greek historian provided Hobbes with a powerful historical demonstration of the destructive effects of faction, ambition, popular demagogy, and political instability. Thucydides consequently became an important intellectual precursor to Hobbes's later theory of civil conflict.

The translation also reveals a characteristic feature of Hobbes's intellectual method: classical texts were not merely objects of antiquarian scholarship but instruments through which the political problems of his own age could be examined.

The Discovery of Geometry and the New Science

Hobbes's intellectual transformation accelerated during his continental travels of the late 1620s and 1630s. A famous anecdote, recorded by John Aubrey, relates that Hobbes encountered a copy of Euclid's Elements and was struck by the demonstrative structure of geometry. According to the story, he initially encountered the Pythagorean theorem and, finding its conclusion apparently impossible, worked backward through the propositions until he understood the demonstration. The anecdote became central to the later mythology of Hobbes as a philosopher who attempted to reconstruct knowledge according to geometrical method.

The exact historical details of the story should nevertheless be treated with caution. What is beyond doubt is that geometry and the idea of demonstrative science became central to Hobbes's mature philosophy.

During his continental travels he encountered the intellectual circles associated with Marin Mersenne, Galileo Galilei, Pierre Gassendi, René Descartes, and other figures of the emerging scientific culture.

His encounter with Galileo was especially significant. Hobbes developed a mechanical conception of nature in which physical reality consists fundamentally of bodies in motion. Human perception, imagination, appetite, aversion, and action were subsequently interpreted within the same general framework.

Hobbes's mature philosophy therefore attempted to eliminate the sharp separation between physics, psychology, and political theory. Human beings are bodies; their mental operations are motions within those bodies; their passions produce actions; and political institutions are artificial constructions created by human beings to control the consequences of these passions.

The Philosophical System: Elementa Philosophiae

Hobbes conceived his philosophy as a systematic science divided into three principal sections:

De Corpore — Body

De Homine — Man

De Cive — Citizen

This structure was intended to proceed from the most general principles of body and motion, through human nature, to the artificial body of the commonwealth.

The intended logical sequence was therefore:

Body → Man → Citizen.

The actual publication sequence was radically different. Because of the English political crisis, Hobbes published the political section first:

De Cive — 1642

Leviathan — 1651

De Corpore — 1655

De Homine — 1658.

This reversal is one of the most important facts in the history of Hobbes's works. The political philosophy for which he became famous was, in his own conception, only the final part of a much larger natural-philosophical system.

The Elements of Law, Natural and Politic

Hobbes's first systematic statement of his mature political philosophy was The Elements of Law, Natural and Politic, composed in 1640. The work circulated in manuscript among politically interested readers and was not originally published as a single book. Hobbes's manuscript tradition is particularly important: several manuscript copies survive, including copies preserved in the Cavendish collection at Chatsworth and in the British Library. In 1650, without Hobbes's authorization, the work was printed in two separate parts:Human Nature, or the Fundamental Elements of Policy and De Corpore Politico, or the Elements of Law, Moral and Politic.

Thus the familiar title The Elements of Law, Natural and Politic refers primarily to the manuscript work of 1640 rather than to a contemporary authorized printed edition. A complete scholarly edition based on the manuscripts was eventually produced by Ferdinand Tönnies in 1889, an event of major importance in Hobbesian textual scholarship. The work already contains many of the principles later developed in De Cive and Leviathan: human equality, competition, fear, the state of nature, the laws of nature, covenant, sovereignty, and the necessity of an undivided political authority.

Exile and De Cive

The political crisis of 1640 profoundly altered Hobbes's circumstances. Fearing that his writings and royalist associations might expose him to danger, he left England for France in late 1640.

In Paris he entered the intellectual world surrounding Mersenne and came into direct contact with leading continental philosophers and mathematicians. The first edition of ** De Cive ** appeared in Paris in 1642 under the title Elementorum Philosophiae Sectio Tertia De Cive. It was a comparatively small edition. A substantially revised second edition appeared at Amsterdam in 1647, printed by the Elzevir press, and this became the principal early Latin form of the work.

The importance of De Cive is enormous. It represents Hobbes's first published systematic exposition of his political philosophy and anticipates much of the argument later developed in Leviathan.

The central problem is the relationship between natural liberty and political obligation. Human beings possess by nature the right to do whatever they judge necessary for their preservation. Yet universal liberty in the absence of a common power generates insecurity. Rational individuals therefore have reasons to seek peace and establish a sovereign authority capable of enforcing covenants.

An English version appeared in 1651 as Philosophicall Rudiments Concerning Government and Society, making the argument available to the English political world just as Leviathan was being published.

Hobbes and Descartes

Hobbes participated in the intellectual controversies surrounding René Descartes's Meditationes de prima philosophia. At Mersenne's request, Hobbes contributed objections to Descartes's Meditations, published in 1641 among the Objectiones and Responsiones. These became known as the Third Objections. Hobbes objected particularly to Cartesian dualism and to the conception of an immaterial thinking substance. His insistence that thought must be understood in relation to corporeal processes was consistent with his broader materialist programme.

The disagreement was therefore not merely personal or terminological. It concerned the fundamental ontology of early modern philosophy: whether thought required an immaterial substance or could be explained through the motions of bodies.

Leviathan: Composition, Publication, and Structure

Hobbes's masterpiece, Leviathan, or The Matter, Forme and Power of a Commonwealth Ecclesiasticall and Civil, appeared in London in 1651, printed for Andrew Crooke. The first edition is one of the most famous books in the history of political thought and in the history of European printing. Its engraved frontispiece depicts the sovereign as a gigantic human figure whose body is composed of hundreds of individual human beings. In his right hand he holds the sword of civil authority; in his left, the staff of ecclesiastical authority.

The image is not merely decorative. It visualizes Hobbes's conception of the commonwealth as an artificial person constituted by the multitude but represented by the sovereign. The first edition is known as the “Head” edition, because of the distinctive ornament on its title page. A second, unauthorized edition, traditionally called the “Bear” edition, appeared with a different title-page ornament and was probably printed in the Netherlands. The two editions are textually significant: they are not simply typographical reproductions, and the first edition itself contains variations because Hobbes was in Paris while the book was being printed in London and corrected proof sheets were exchanged imperfectly. Large-paper copies of the first edition preserve some of Hobbes's later corrections.

The textual history of Leviathan is therefore unusually complex. The 1651 English text cannot simply be treated as a single mechanically uniform state of the book.

The Four Parts of Leviathan

Leviathan consists of four parts:

Of Man

Hobbes begins with an analysis of human nature. Sensation, imagination, memory, language, reason, passion, appetite, aversion, and voluntary motion are treated within a broadly mechanical framework.

Reason is famously defined as a form of reckoning or computation, particularly the addition and subtraction of consequences.

Human beings are fundamentally moved by appetites and aversions. There is no Aristotelian natural final cause directing human beings toward an objectively defined good. Instead, what individuals call good and evil depends upon their appetites and aversions.

The famous proposition that human beings possess a “perpetuall and restlesse desire of Power after power” is therefore inseparable from Hobbes's anthropology.

Of Commonwealth

The second part develops the theory of political sovereignty.

In the state of nature, individuals possess extensive natural liberty but lack an effective common authority. Because individuals are sufficiently equal in vulnerability and capacity to threaten one another, insecurity becomes pervasive.

The resulting condition is the famous state of war, in which there is no assured peace and no common power capable of enforcing agreements. Hobbes's solution is the creation of the artificial person of the commonwealth. An important conceptual correction is necessary here: the sovereign is not simply one of the parties to the social contract. The fundamental covenant is made among individuals, who authorize the sovereign to act in their name. Sovereignty is therefore not merely delegated government but the constitutive principle that creates the political person.

The sovereign must possess sufficiently undivided authority to make peace possible. Yet Hobbes also recognizes a limit that becomes fundamental to later interpretations: an individual cannot be understood as obliged to abandon the most basic right of self-preservation.

Of a Christian Commonwealth

The third part is one of the most controversial and important sections of Leviathan.

Hobbes subjects Scripture, prophecy, miracles, revelation, ecclesiastical authority, and Christian political organization to his theory of sovereignty. He rejects the existence of an independent ecclesiastical jurisdiction capable of competing with civil sovereignty. In his account, the authority to determine publicly recognized doctrine belongs to the sovereign commonwealth.

This is not simply conventional Erastianism. Hobbes's treatment of Christianity is considerably more radical because it is embedded within his materialist philosophy of language, revelation, prophecy, and political representation.

Of the Kingdome of Darknesse

The fourth part attacks the intellectual and institutional forces that Hobbes believes have obscured rational understanding and weakened civil sovereignty. He attacks Scholastic philosophy, ecclesiastical power, papal authority, the doctrine of incorporeal substances, and various forms of theological superstition.

The section is polemical, satirical, and deliberately provocative. It is also central to understanding why Leviathan generated such intense hostility among both religious and political opponents.

The Latin Leviathan of 1668

One of the most important facts in the editorial history of Hobbes is that the Latin Leviathan of 1668 is not simply a translation of the English edition of 1651. It appeared in Amsterdam in the collection Thomae Hobbes Malmesburiensis Opera Philosophica quae Latine Scripsit Omnia, printed by Joannes Blaeu. The Latin text contains substantial revisions, omissions, additions, and reformulations. Particularly important are the changes concerning theological questions, the Trinity, the interpretation of Scripture, and the relation between philosophy and theology.

Consequently, the two versions must be studied as distinct textual witnesses to Hobbes's thought rather than as identical English and Latin editions. The 1668 Latin text is indispensable for reconstructing the final development of Hobbes's political and theological philosophy.

Return to England and De Corpore

Hobbes returned to England in 1651 and continued to develop the philosophical system of which Leviathan represented the political culmination. The first section of the planned Elementa Philosophiae, ** De Corpore **, appeared in London in 1655 as Elementorum Philosophiae Sectio Prima De Corpore.

The work contains Hobbes's systematic treatment of:

• logic and method;
• language and names;
• first philosophy;
• geometry;
• motion;
• matter;
• magnitude;
• mechanics;
• natural philosophy.

For Hobbes, philosophy concerns bodies and their properties, and explanation proceeds through the generation and effects of bodies in motion.

The work therefore provides the metaphysical and methodological foundation that Leviathan presupposes.

De Homine

The second section of the philosophical system, ** De Homine **, appeared in 1658. It deals with human beings after the general analysis of body undertaken in De Corpore. Particular attention is given to perception, imagination, passions, human action, and optics. With De Homine, Hobbes formally completed the tripartite structure of the Elementa Philosophiae, although the political component, De Cive, had of course appeared sixteen years earlier.

The resulting trilogy was therefore:

De Corpore — natural philosophy and method

De Homine — anthropology and psychology

De Cive — political philosophy.

Liberty, Necessity, and the Bramhall Controversy

One of Hobbes's most important non-political controversies concerned free will and necessity.

His debate with John Bramhall, Bishop of Derry, began in the 1640s and continued through several exchanges. Hobbes's position was deterministic but not simply equivalent to the modern claim that human beings are passive machines. He argued that voluntary actions can be free in the relevant sense while still being causally determined. Liberty concerns the absence of external impediments, whereas necessity concerns the causal order through which actions arise.

The principal exchange was eventually published in: Of Libertie and Necessitie (1654) and The Questions Concerning Liberty, Necessity, and Chance (1656). These writings are indispensable for understanding Hobbes's philosophy of action and the conceptual foundations of later compatibilist theories.

Hobbes versus Wallis and the Royal Society

After the publication of De Corpore, Hobbes became embroiled in increasingly bitter mathematical controversies, particularly with John Wallis, Savilian Professor of Geometry at Oxford. Hobbes claimed to have solved problems that mathematicians considered insoluble or extraordinarily difficult, including problems connected with the quadrature of the circle and duplication of the cube.

Wallis responded with sustained and often devastating mathematical criticism. The dispute became personal as well as technical and continued for years.

Hobbes's mathematical arguments were ultimately unsuccessful, but the controversy is historically important because it reveals the tension between his philosophical conception of demonstrative science and the rapidly developing mathematical practices of the seventeenth century.

Hobbes and Robert Boyle: Vacuum and Experimental Science

Hobbes also became an opponent of the experimental programme associated with Robert Boyle and the newly founded Royal Society. In 1661, Hobbes published Dialogus Physicus de Natura Aeris, attacking aspects of Boyle's experimental investigation of air and the vacuum.

Hobbes rejected the existence of a true vacuum and objected to the epistemological status of experimental demonstrations that did not, in his view, establish universal causal necessity. The controversy became one of the classic confrontations between two models of early modern science:

• Hobbes's deductive, mechanical, geometrical ideal of demonstration;
• Boyle's experimental, observational, and corpuscular methodology.

The dispute later became historically important in the work of historians of science such as Steven Shapin and Simon Schaffer.

The Political and Religious Problems of the Restoration

The Restoration of Charles II in 1660 placed Hobbes in a complicated position. Charles II had known Hobbes during his exile in France, where Hobbes had served as mathematical tutor to the future king. The Restoration therefore did not simply destroy Hobbes's position at court. Nevertheless, Leviathan had alienated almost every major political and religious constituency: royalists regarded it as insufficiently royalist and dangerously supportive of obedience to whoever possessed effective power; Anglicans objected to its subordination of ecclesiastical authority to the sovereign; Catholics and Presbyterians alike rejected its attack on independent ecclesiastical jurisdiction.

Hobbes consequently became increasingly vulnerable to accusations of atheism and irreligion. The controversy reached Parliament in 1666, when legislation concerning atheism and profaneness specifically raised Leviathan as a problematic book. Hobbes was not formally convicted of atheism, but the political climate made further publication of controversial works in England increasingly difficult.

Behemoth and the History of the Civil Wars

Hobbes's history of the English Civil Wars, ** Behemoth, or The Long Parliament **, was written in the late 1660s, traditionally dated around 1668. The work takes the form of a dialogue concerning the causes and development of the English Civil Wars from 1640 onward.

It is particularly valuable because Hobbes interprets the Civil Wars through the conceptual categories developed in his political philosophy: faction, religious division, competing claims to authority, popular rhetoric, institutional conflict, and the breakdown of sovereign power. Charles II refused to authorize publication. Hobbes's manuscript nevertheless circulated, and unauthorized European editions appeared.

The first genuine edition was published posthumously, in 1681/1682, by William Crooke, Hobbes's publisher and literary agent. The surviving evidence shows that Crooke attempted to present a more reliable text than the unauthorized editions and that Hobbes himself had regretted the appearance of unlicensed versions.

Behemoth therefore occupies a peculiar position in Hobbes's bibliography: composed during his lifetime, suppressed from authorized publication, circulated in unauthorized forms, and only properly published after his death.

The Later Works

Hobbes remained extraordinarily productive during his eighties.

Among his later works were writings on geometry and mathematics, polemical responses to Wallis, philosophical problems, natural philosophy, theology, and history.

His ** Dialogus Physicus de Natura Aeris ** appeared in 1661.

His ** Seven Philosophical Problems ** appeared in the early 1670s.

His ** Decameron Physiologicum ** was published in 1678, representing a late statement of his natural-philosophical interests.

He also composed the ** Historia Ecclesiastica Carmine Elegiaco Concinnata **, an extensive Latin verse history of the Church, which was published only after his death.

These late works demonstrate that Hobbes never abandoned the ambition to produce a comprehensive philosophy extending beyond political theory.

Homer and the Return to Classical Literature

In his final years Hobbes returned conspicuously to the classical literature that had formed his youth.

He translated Homer's Iliad and Odyssey into English verse. The Iliad appeared in 1675 and the Odyssey in 1675–1676, in successive publications. These translations are important for more than biographical reasons. Hobbes's entire intellectual career had been marked by an engagement with classical texts, from his early study of Greek and Latin to his translation of Thucydides and his later Homeric work. The translations also demonstrate that the elderly Hobbes remained engaged with questions of literary form, rhetoric, political history, and the relationship between ancient and modern culture.

Death

Hobbes spent his final years under the protection of the Cavendish family. He died on 4 December 1679 at Hardwick Hall, Derbyshire, at the age of ninety-one. He was buried at St John the Baptist's Church, Ault Hucknall, near Hardwick. His death did not terminate the publication of his works. On the contrary, the decades following his death witnessed a continuing stream of editions, translations, polemics, biographies, and collected works.

The Early Posthumous Tradition

An important early source for Hobbes's biography is the collection ** T. Hobbes Malmesburiensis Vita **, published at Charleville in 1681. It brought together several biographical materials, including Hobbes's own autobiographical writings, the biographical material associated with John Aubrey, and Hobbes's Latin verse autobiography. These sources established many of the anecdotes that subsequently shaped the traditional image of Hobbes: his premature birth during the Armada crisis, his precocious education, his discovery of Euclidean geometry, his continental travels, his intellectual controversies, and his extraordinary longevity. Because these biographies were composed within or close to Hobbes's own lifetime, they remain indispensable, but they must be treated critically. Later scholarship has demonstrated that some of the anecdotes were shaped by retrospective self-fashioning and by the conventions of seventeenth-century philosophical biography.

The Eighteenth-Century Reception

Hobbes's reputation in the eighteenth century was deeply controversial. The term “Hobbism” was frequently used polemically to associate his philosophy with atheism, materialism, moral relativism, and political absolutism. Yet Hobbes's influence extended across precisely the intellectual traditions that opposed him. His theory of natural right, his analysis of the state of nature, and his account of political obligation profoundly affected the development of modern natural-law theory.

Spinoza, Pufendorf, Locke, and Rousseau all developed political philosophies in intellectual environments in which Hobbes's arguments could not simply be ignored. Locke rejected Hobbes's absolutism but retained important elements of the contractual framework. Rousseau radically transformed the concept of sovereignty by relocating it in the collective people rather than in an individual sovereign. Spinoza adapted Hobbesian ideas of natural power and right to a different theory of political association and religious authority. Hobbes's influence therefore cannot be measured simply by identifying philosophers who agreed with him. His opponents were often among his most important intellectual heirs.

The History of Hobbes's Printed Works

The editorial history of Hobbes's works is unusually complex because several of his most important texts existed in different manuscript, English, and Latin forms. His bibliography can be divided into several major phases.

The early humanist phase

The first printed phase is represented principally by the 1629 Thucydides, followed by its reissues and by shorter literary and classical works.

The political manuscripts of the 1640s

The Elements of Law circulated primarily in manuscript before being printed without authorization in 1650.

The Latin political phase

De Cive was first printed in 1642 and substantially revised in 1647.

The English Leviathan phase

The 1651 Leviathan became Hobbes's most famous English publication and generated an unusually complicated textual and typographical tradition.

The systematic philosophical phase

De Corpore (1655) and De Homine (1658) completed the planned Elementa Philosophiae.

The Latin collected phase

The 1668 Opera Philosophica brought together Hobbes's Latin philosophical works and included the substantially revised Latin Leviathan.

The late English and posthumous phase

Hobbes's later English works—including Behemoth, the mathematical controversies, and his translations of Homer—were published in circumstances ranging from royal censorship to unauthorized circulation and posthumous publication.

The Major Collected Editions

The first important large-scale collection was ** The Moral and Political Works of Thomas Hobbes of Malmesbury **, published in London in 1750. It gathered a substantial selection of Hobbes's moral and political writings and included a biography.

The decisive nineteenth-century achievement was Sir William Molesworth's collected edition.

Molesworth published:

The English Works of Thomas Hobbes of Malmesbury, 11 volumes, London, 1839–1845; and Thomae Hobbes Malmesburiensis Opera Philosophica quae Latine Scripsit Omnia, 5 volumes, London, 1839–1845.

The English collection includes De Corpore, De Cive, Leviathan, Behemoth, the writings on liberty and necessity, the mathematical controversies, the Dialogue, Hobbes's Thucydides, and his Homer translations. Molesworth's edition remained the fundamental collected edition of Hobbes for more than a century. It is still indispensable bibliographically, but it is not a modern critical edition and does not incorporate the full manuscript and correspondence tradition.

The Molesworth volumes were repeatedly reprinted, including the important twentieth-century reprint by Scientia Verlag, Aalen, 1962.

The Modern Critical Edition: The Clarendon Edition

The twentieth and twenty-first centuries witnessed a fundamental transformation in Hobbesian textual scholarship. Oxford University Press's Clarendon Edition of the Works of Thomas Hobbes was conceived as a critical edition designed to replace the nineteenth-century Molesworth collection as the scholarly standard. Among its most important achievements is the edition of De Cive by Howard Warrender, which presents both the Latin and English versions.

The Correspondence of Thomas Hobbes, edited by Noel Malcolm, appeared in two volumes in 1994 and dramatically expanded the documentary basis for understanding Hobbes's intellectual networks, publication history, and relations with other scholars. The most monumental achievement to date is Noel Malcolm's three-volume edition of Leviathan, published in 2012 as volumes III–V of the Clarendon Edition of the Works of Thomas Hobbes.

Malcolm's edition presents the English and Latin texts in parallel and reconstructs the development of the text from manuscript through the English edition of 1651 and the Latin version of 1668. Its apparatus records textual variants and its introductory volume provides an extensive reconstruction of the composition, transmission, printing, and revision of Leviathan. It is now the indispensable scholarly edition of the work. Other important modern editions include:

Ferdinand Tönnies, The Elements of Law, Natural and Politic (1889), which reconstructed the work from manuscript evidence;

Howard Warrender, De Cive: The Latin Version and De Cive: The English Version (Oxford, 1983);

Richard Tuck, Leviathan (Cambridge, 1991);

Edwin Curley, Leviathan, with Selected Variants from the Latin Edition of 1668 (Indianapolis, 1994);

J. C. A. Gaskin, The Elements of Law (Oxford, 1994);

Bernard Gert, On the Citizen (Cambridge, 1998);

and Paul Seaward's modern edition of Behemoth for the Clarendon tradition.

The scholarly situation has therefore changed fundamentally since Molesworth. The modern study of Hobbes requires attention not merely to the text as traditionally printed but to manuscript witnesses, unauthorized editions, alternative English and Latin versions, authorial revisions, correspondence, and the material history of individual books.

Hobbes's Philosophical Legacy

Hobbes's philosophical importance rests on the extraordinary unity of his system.

His nominalism led him to emphasize the role of names and definitions in philosophical reasoning. His materialism restricted philosophy to bodies and their properties. His mechanics explained natural phenomena through motion. His psychology interpreted perception and passion through bodily processes. His theory of action linked desire and aversion to voluntary motion. His political philosophy then constructed the commonwealth as an artificial body created to secure peace. The result was one of the first genuinely comprehensive attempts to construct a modern philosophy without relying upon Aristotelian teleology.

His conception of the state of nature became one of the most influential thought experiments in political philosophy.

His theory of sovereignty transformed the vocabulary of political authority.

His conception of the artificial person anticipated later theories of corporate personality and representation.

His analysis of covenant and authorization became fundamental to modern contractarian thought.

His theory of liberty and necessity remains central to debates concerning determinism and free will.

His analysis of language, definition, and reasoning as computation contributed to the emergence of modern theories of semantics and rational calculation.

And his materialist account of human beings anticipated, in important respects, later naturalistic approaches to psychology and philosophy of mind.

Twentieth-Century Reinterpretation

Hobbes's modern revival began in large part with the work of Ferdinand Tönnies, whose Thomas Hobbes: Leben und Lehre (1896) helped establish systematic modern Hobbes scholarship.

The twentieth century subsequently produced radically different interpretations.

Leo Strauss emphasized Hobbes's break with classical natural law and interpreted him as a foundational figure in the transformation of modern political philosophy.

C. B. Macpherson famously interpreted Hobbes through the concept of possessive individualism, relating his anthropology to the emerging structures of competitive market society.

Howard Warrender emphasized the moral and normative foundations of Hobbes's theory of obligation.

Richard Tuck situated Hobbes within the history of natural rights, international law, and early modern political thought.

Quentin Skinner and the Cambridge School placed Hobbes within the precise rhetorical, political, and intellectual contexts of seventeenth-century England and challenged interpretations that detached his texts from their historical languages.

Noel Malcolm subsequently transformed the field through his work on Hobbes's biography, correspondence, manuscripts, textual history, and the material history of Leviathan.

Thomas Hobbes occupies a singular position in the history of European thought because he combined a radical theory of political sovereignty with a radical theory of matter, motion, language, and human nature. His political philosophy cannot be isolated from his natural philosophy. The commonwealth is an artificial body; human beings are natural bodies; passions are motions; reason is calculation; political authority is an artificial power created to regulate the consequences of natural human vulnerability.

At the centre of the system stands a stark anthropological insight: human beings are sufficiently equal in their capacity to harm one another that peaceful coexistence cannot be taken for granted. Political order therefore requires an artificial power capable of making covenants effective. The originality of Hobbes lies not simply in his advocacy of strong government. His deeper achievement was to reconstruct political philosophy from the foundations upward. Instead of beginning with the traditional question of the best regime, he began with bodies, motion, desire, vulnerability, language, conflict, and the problem of collective security.

The publication history of his works mirrors this intellectual revolution. The manuscript Elements of Law, the successive editions of De Cive, the typographically extraordinary Leviathan of 1651, the revised Latin Leviathan of 1668, the systematic De Corpore and De Homine, the controversial Behemoth, and the enormous nineteenth- and twentieth-century editorial enterprises all testify to the unusual textual life of his philosophy.

Hobbes therefore belongs simultaneously to the history of political philosophy, metaphysics, materialism, early modern science, classical scholarship, theology, rhetoric, mathematics, and the history of the book. His works have never ceased to provoke disagreement because the problems they formulate remain unresolved: How much liberty can coexist with security? What makes political authority legitimate? Can rational individuals create binding obligations? Is human action compatible with causal necessity? What is the relationship between religion and sovereign power? Can political order exist without a common authority?

Few philosophers have formulated these questions with greater systematic force. And few have left behind a textual tradition in which the history of the ideas is so inseparable from the history of their manuscripts, editions, printers, revisions, translations, censorship, and reception.
