Thomas Hobbes (5 April 1588 – 4 December 1679) was an English philosopher, remembered today for his work on political philosophy. His 1651 book Leviathan established the foundation for most of Western political philosophy from the perspective of social contract theory.[1] Hobbes also contributed to a diverse array of fields, including history, geometry, physics of gases, theology, ethics, general philosophy, and political science. His account of human nature as self-interested cooperation has proved to be an enduring theory in the field of philosophical anthropology. He was one of the main philosophers who founded materialism. Thomas Hobbes was born in Wiltshire, England on 5 April 1588, some sources say at Malmesbury[2]. Born prematurely on April 5, 1588, when his mother heard of the coming invasion of the Spanish Armada, Thomas Hobbes later reported that "my mother gave birth to twins: myself and fear."[3] His childhood is almost a complete blank, and his mother's name is unknown.[4] His father, also named Thomas, was the vicar of Charlton and Westport. Thomas Sr. abandoned his three children to the care of an older brother, Thomas junior's uncle Francis, when he was forced to flee to London after being involved in a fight with a clergyman outside his own church. Hobbes was educated at Westport church from the age of four, passed to the Malmesbury school and then to a private school kept by a young man named Robert Latimer, a graduate of the University of Oxford. Hobbes was a good pupil, and around 1603 he went up to Magdalen Hall, which is most closely related to Hertford College, Oxford.[5][6][7][8] The principal John Wilkinson was a Puritan, and he had some influence on Hobbes. At university, Hobbes appears to have followed his own curriculum; he was "little attracted by the scholastic learning". He did not complete his B.A. degree until 1608, but he was recommended by Sir James Hussey, his master at Magdalen, as tutor to William, the son of William Cavendish, Baron of Hardwick (and later Earl of Devonshire), and began a life-long connection with that family.[9] Hobbes became a companion to the younger William and they both took part in a grand tour in 1610. Hobbes was exposed to European scientific and critical methods during the tour in contrast to the scholastic philosophy which he had learned in Oxford. His scholarly efforts at the time were aimed at a careful study of classic Greek and Latin authors, the outcome of which was, in 1628, his great translation of Thucydides' History of the Peloponnesian War, the first translation of that work into English from a Greek manuscript. Although he associated with literary figures like Ben Jonson and thinkers such as Francis Bacon, he did not extend his efforts into philosophy until after 1629. His employer Cavendish, then the Earl of Devonshire, died of the plague in June 1628. The widowed countess dismissed Hobbes but he soon found work, again as a tutor, this time to the son of Sir Gervase Clifton. This task, chiefly spent in Paris, ended in 1631 when he again found work with the Cavendish family, tutoring the son of his previous pupil. Over the next seven years as well as tutoring he expanded his own knowledge of philosophy, awakening in him curiosity over key philosophic debates. He visited Florence in 1636 and later was a regular debater in philosophic groups in Paris, held together by Marin Mersenne. From 1637 he considered himself a philosopher and scholar. Hobbes's first area of study was an interest in the physical doctrine of motion and physical momentum. Despite his interest in this phenomenon, he disdained experimental work as in physics. He went on to conceive the system of thought to the elaboration of which he would devote his life. His scheme was first to work out, in a separate treatise, a systematic doctrine of body, showing how physical phenomena were universally explicable in terms of motion, at least as motion or mechanical action was then understood. He then singled out Man from the realm of Nature and plants. Then, in another treatise, he showed what specific bodily motions were involved in the production of the peculiar phenomena of sensation, knowledge, affections and passions whereby Man came into relation with Man. Finally he considered, in his crowning treatise, how Men were moved to enter into society, and argued how this must be regulated if Men were not to fall back into "brutishness and misery". Thus he proposed to unite the separate phenomena of Body, Man, and the State. Hobbes came home, in 1637, to a country riven with discontent which disrupted him from the orderly execution of his philosophic plan. However, by the end of the Short Parliament in 1640, he had written a short treatise called The Elements of Law, Natural and Politic. It was not published and only circulated among his acquaintances in manuscript form. A pirated version, however, was published about ten years later. Although it seems that much of The Elements of Law was composed before the sitting of the Short Parliament, there are polemical pieces of the work that clearly mark the influences of the rising political crisis. Nevertheless, many (though not all) elements of Hobbes's political thought were unchanged between The Elements of Law and Leviathan, which demonstrates that the events of the English Civil War had little effect on his contractarian methodology. It should be noted, however, that the arguments in Leviathan were modified from The Elements of Law when it came to the necessity of consent in creating political obligation. Namely, Hobbes wrote in The Elements of Law that Patrimonial kingdoms were not necessarily formed by the consent of the governed, while in Leviathan he argued that they were. This was perhaps a reflection either of Hobbes's thoughts concerning the engagement controversy or of his reaction to treatises published by Patriarchalists, such as Sir Robert Filmer, between 1640 and 1651. When in November 1640 the Long Parliament succeeded the Short, Hobbes felt he was a marked man by the circulation of his treatise and fled to Paris. He did not return for eleven years. In Paris he rejoined the coterie about Mersenne, and wrote a critique of the Meditations on First Philosophy of Descartes, which was printed as third among the sets of "Objections" appended, with "Replies" from Descartes in 1641. A different set of remarks on other works by Descartes succeeded only in ending all correspondence between the two. Hobbes also extended his own works somewhat, working on the third section, De Cive, which was finished in November 1641. Although it was initially only circulated privately, it was well received, and included lines of argumentation to be repeated a decade later in the Leviathan. He then returned to hard work on the first two sections of his work and published little except for a short treatise on optics (Tractatus opticus) included in the collection of scientific tracts published by Mersenne as Cogitata physico-mathematica in 1644. He built a good reputation in philosophic circles and in 1645 was chosen with Descartes, Gilles de Roberval and others, to referee the controversy between John Pell and Longomontanus over the problem of squaring the circle. The English Civil War broke out in 1642, and when the Royalist cause began to decline in the middle of 1644 there was an exodus of the king's supporters to Europe. Many came to Paris and were known to Hobbes. This revitalised Hobbes's political interests and the De Cive was republished and more widely distributed. The printing began in 1646 by Samuel de Sorbiere through the Elsevier press at Amsterdam with a new preface and some new notes in reply to objections. In 1647, Hobbes was engaged as mathematical instructor to the young Charles, Prince of Wales,[10] who had come over from Jersey around July. This engagement lasted until 1648 when Charles went to Holland. The company of the exiled royalists led Hobbes to produce an English book to set forth his theory of civil government in relation to the political crisis resulting from the war. The State, it now seemed to Hobbes, might be regarded as a great artificial man or monster (Leviathan), composed of men, with a life that might be traced from its generation under pressure of human needs to its dissolution through civil strife proceeding from human passions. The work was closed with a general "Review and Conclusion", in direct response to the war which raised the question of the subject's right to change allegiance when a former sovereign's power to protect was irrecoverably gone. Also he criticized religious doctrines on rationalistic grounds in the Commonwealth. During the years of the composition of Leviathan he remained in or near Paris. In 1647 Hobbes was overtaken by a serious illness which disabled him for six months. On recovering from this near fatal disorder, he resumed his literary task, and carried it steadily forward to completion by the year 1650. Meanwhile, a translation of De Cive was being produced; there has been much scholarly disagreement over whether Hobbes translated the work himself or not. In 1650, a pirated edition of The Elements of Law, Natural and Politic was published. It was divided into two separate small volumes (Human Nature, or the Fundamental Elements of Policie and De corpore politico, or the Elements of Law, Moral and Politick). In 1651 the translation of De Cive was published under the title of Philosophicall Rudiments concerning Government and Society. Meanwhile, the printing of the greater work was proceeding, and finally it appeared about the middle of 1651, under the title of Leviathan, or the Matter, Forme, and Power of a Common Wealth, Ecclesiasticall and Civil, with a famous title-page engraving in which, from behind hills overlooking a landscape, there towered the body (above the waist) of a crowned giant, made up of tiny figures of human beings and bearing sword and crozier in the two hands. The work had immediate impact. Soon Hobbes was more lauded and decried than any other thinker of his time. However, the first effect of its publication was to sever his link with the exiled royalists, forcing him to appeal to the revolutionary English government for protection. The exiles might very well have killed him; the secularist spirit of his book greatly angered both Anglicans and French Catholics. Hobbes fled back home, arriving in London in the winter of 1651. Following his submission to the council of state he was allowed to subside into private life in Fetter Lane.
