René Descartes (Latinized form: ''Renatus Cartesius''; adjectival form: "Cartesian"; 31 March 1596 – 11 February 1650) was a French philosopher, mathematician, and writer who spent most of his adult life in the Dutch Republic. He has been dubbed the 'Father of Modern Philosophy', and much subsequent Western philosophy is a response to his writings, which are studied closely to this day. In particular, his ''Meditations on First Philosophy'' continues to be a standard text at most university philosophy departments. Descartes' influence in mathematics is equally apparent; the Cartesian coordinate system — allowing algebraic equations to be expressed as geometric shapes in a two-dimensional coordinate system — was named after him. He is credited as the father of analytical geometry, the bridge between algebra and geometry, crucial to the discovery of infinitesimal calculus and analysis. Descartes was also one of the key figures in the Scientific Revolution and has been described as an example of genius.

Descartes frequently sets his views apart from those of his predecessors. In the opening section of the ''Passions of the Soul'', a treatise on the Early Modern version of what are now commonly called emotions, Descartes goes so far as to assert that he will write on this topic "as if no one had written on these matters before". Many elements of his philosophy have precedents in late Aristotelianism, the revived Stoicism of the 16th century, or in earlier philosophers like St. Augustine. In his natural philosophy, he differs from the schools on two major points: First, he rejects the analysis of corporeal substance into matter and form; second, he rejects any appeal to ends—divine or natural—in explaining natural phenomena. In his theology, he insists on the absolute freedom of God’s act of creation.

Descartes was a major figure in 17th-century continental rationalism, later advocated by Baruch Spinoza and Gottfried Leibniz, and opposed by the empiricist school of thought consisting of Hobbes, Locke, Berkeley, Jean-Jacques Rousseau, and Hume. Leibniz, Spinoza and Descartes were all well versed in mathematics as well as philosophy, and Descartes and Leibniz contributed greatly to science as well.

He is perhaps best known for the philosophical statement "''Cogito ergo sum''" (; ), found in part IV of ''Discourse on the Method'' (1637 – written in French but with inclusion of "Cogito ergo sum") and §7 of part I of ''Principles of Philosophy'' (1644 – written in Latin).

Biography[link]

Descartes was born in La Haye en Touraine (now Descartes), Indre-et-Loire, France. When he was one year old, his mother Jeanne Brochard died. His father Joachim was a member in the provincial parliament. At the age of eight, he entered the Jesuit Collège Royal Henry-Le-Grand at La Flèche. After graduation in December 1616, he studied at the University of Poitiers, earning a ''Baccalauréat'' and ''Licence'' in law, in accordance with his father's wishes that he should become a lawyer.

"I entirely abandoned the study of letters. Resolving to seek no knowledge other than that of which could be found in myself or else in the great book of the world, I spent the rest of my youth traveling, visiting courts and armies, mixing with people of diverse temperaments and ranks, gathering various experiences, testing myself in the situations which fortune offered me, and at all times reflecting upon whatever came my way so as to derive some profit from it." (Descartes, ''Discourse on the Method'').

In 1618, Descartes was engaged in the army of Maurice of Nassau in the Dutch Republic, but as a truce had been established between Holland and Spain, Descartes used his spare time to study mathematics. In this way he became acquainted with Isaac Beeckman, principal of Dordrecht school. Beeckman had proposed a difficult mathematical problem, and to his astonishment, it was the young Descartes who found the solution. Both believed that it was necessary to create a method that thoroughly linked mathematics and physics. While in the service of the Duke Maximilian of Bavaria, Descartes was present at the Battle of the White Mountain outside Prague, in November 1620.

On the night of 10–11 November 1619, while stationed in Neuburg an der Donau, Germany, Descartes experienced a series of three powerful dreams or visions that he later claimed profoundly influenced his life. He concluded from these visions that the pursuit of science would prove to be, for him, the pursuit of true wisdom and a central part of his life's work. Descartes also saw very clearly that all truths were linked with one another, so that finding a fundamental truth and proceeding with logic would open the way to all science. This basic truth, Descartes found quite soon: his famous "I think".

In 1622 he returned to France, and during the next few years spent time in Paris and other parts of Europe. It was during a stay in Paris that he composed his first essay on method: ''Regulae ad Directionem Ingenii'' (Rules for the Direction of the Mind). He arrived in La Haye in 1623, selling all of his property to invest in bonds, which provided a comfortable income for the rest of his life. Descartes was present at the siege of La Rochelle by Cardinal Richelieu in 1627.

He returned to the Dutch Republic in 1628, where he lived until September 1649. In April 1629 he joined the University of Franeker, living at the Sjaerdemaslot, and the next year, under the name "Poitevin", he enrolled at the Leiden University to study mathematics with Jacob Golius and astronomy with Martin Hortensius. In October 1630 he had a falling-out with Beeckman, whom he accused of plagiarizing some of his ideas. In Amsterdam, he had a relationship with a servant girl, Helena Jans van der Strom, with whom he had a daughter, Francine, who was born in 1635 in Deventer, at which time Descartes taught at the Utrecht University. Francine Descartes died in 1640 in Amersfoort, from Scarlet Fever.

While in the Netherlands he changed his address frequently, living among other places in Dordrecht (1628), Franeker (1629), Amsterdam (1629–30), Leiden (1630), Amsterdam (1630–32), Deventer (1632–34), Amsterdam (1634–35), Utrecht (1635–36), Leiden (1636), Egmond (1636–38), Santpoort (1638–1640), Leiden (1640–41), Endegeest (a castle near Oegstgeest) (1641–43), and finally for an extended time in Egmond-Binnen (1643–49).

Despite these frequent moves he wrote all his major work during his 20-plus years in the Netherlands, where he managed to revolutionize mathematics and philosophy. In 1633, Galileo was condemned by the Roman Catholic Church, and Descartes abandoned plans to publish ''Treatise on the World'', his work of the previous four years. Nevertheless, in 1637 he published part of this work in three essays: ''Les Météores'' (The Meteors), ''La Dioptrique'' (Dioptrics) and ''La Géométrie'' (Geometry), preceded by an introduction, his famous ''Discours de la Métode'' (Discourse on the Method). In it Descartes lays out four rules of thought, meant to ensure that our knowledge rests upon a firm foundation.

Descartes continued to publish works concerning both mathematics and philosophy for the rest of his life. In 1641 he published a metaphysics work, ''Meditationes de Prima Philosophia'' (Meditations on First Philosophy), written in Latin and thus addressed to the learned. It was followed, in 1644, by ''Principia Philosophiæ'' (Principles of Philosophy), a kind of synthesis of the Meditations and the Discourse. In 1643, Cartesian philosophy was condemned at the University of Utrecht, and Descartes began his long correspondence with Princess Elisabeth of Bohemia, devoted mainly to moral and psychological subjects. Connected with this correspondence, in 1649 he published ''Les Passions de l'âme'' (Passions of the Soul), that he dedicated to the Princess. In 1647, he was awarded a pension by the King of France. Descartes was interviewed by Frans Burman at Egmond-Binnen in 1648.

A French translation of ''Principia Philosophiæ'', prepared by Abbot Claude Picot, was published in 1647. This edition Descartes dedicated to Princess Elisabeth of Bohemia. In the preface Descartes praised true philosophy as a means to attain wisdom. He identifies four ordinary sources to reach wisdom, and finally says that there is a fifth, better and more secure, consisting in the search for first causes.

René Descartes died on 11 February 1650 in Stockholm, Sweden, where he had been invited as a tutor for Queen Christina of Sweden. The cause of death was said to be pneumonia; accustomed to working in bed until noon, he may have suffered damage to his health from Christina's demands for early morning study (the lack of sleep could have severely compromised his immune system). Descartes stayed at the French ambassador Pierre Chanut.

In 1663, the Pope placed his works on the Index of Prohibited Books.

As a Roman Catholic in a Protestant nation, he was interred in a graveyard used mainly for unbaptized infants in Adolf Fredriks kyrka in Stockholm. Later, his remains were taken to France and buried in the Abbey of Saint-Germain-des-Prés in Paris. Although the National Convention in 1792 had planned to transfer his remains to the Panthéon, they are, two centuries later, still resting between two other graves — those of the scholarly monks Jean Mabillon and Bernard de Montfaucon — in a chapel of the abbey. His memorial, erected in the 18th century, remains in the Swedish church.

Religious beliefs[link]

The religious beliefs of René Descartes have been rigorously debated within scholarly circles. He claimed to be a devout Roman Catholic, claiming that one of the purposes of the ''Meditations'' was to defend the Christian faith. However, in his own era, Descartes was accused of harboring secret deist or atheist beliefs. Contemporary Blaise Pascal said that "I cannot forgive Descartes; in all his philosophy, Descartes did his best to dispense with God. But Descartes could not avoid prodding God to set the world in motion with a snap of his lordly fingers; after that, he had no more use for God."

Stephen Gaukroger's biography of Descartes reports that "he had a deep religious faith as a Catholic, which he retained to his dying day, along with a resolute, passionate desire to discover the truth." After Descartes died in Sweden, Queen Christina abdicated her throne to convert to Roman Catholicism (Swedish law required a Protestant ruler). The only Roman Catholic with whom she had prolonged contact was Descartes, who was her personal tutor.

Philosophical work[link]

Descartes is often regarded as the first thinker to emphasize the use of reason to develop the natural sciences. For him the philosophy was a thinking system that embodied all knowledge, and expressed it in this way: In his ''Discourse on the Method'', he attempts to arrive at a fundamental set of principles that one can know as true without any doubt. To achieve this, he employs a method called hyperbolical/metaphysical doubt, also sometimes referred to as methodological skepticism: he rejects any ideas that can be doubted, and then reestablishes them in order to acquire a firm foundation for genuine knowledge.

Initially, Descartes arrives at only a single principle: thought exists. Thought cannot be separated from me, therefore, I exist (''Discourse on the Method'' and ''Principles of Philosophy''). Most famously, this is known as ''cogito ergo sum'' (English: "I think, therefore I am"). Therefore, Descartes concluded, if he doubted, then something or someone must be doing the doubting, therefore the very fact that he doubted proved his existence. "The simple meaning of the phrase is that if one is skeptical of existence, that is in and of itself proof that he does exist."

Descartes concludes that he can be certain that he exists because he thinks. But in what form? He perceives his body through the use of the senses; however, these have previously been unreliable. So Descartes determines that the only indubitable knowledge is that he is a ''thinking thing''. Thinking is what he does, and his power must come from his essence. Descartes defines "thought" (''cogitatio'') as "what happens in me such that I am immediately conscious of it, insofar as I am conscious of it". Thinking is thus every activity of a person of which he is immediately conscious.

To further demonstrate the limitations of the senses, Descartes proceeds with what is known as the ''Wax Argument''. He considers a piece of wax; his senses inform him that it has certain characteristics, such as shape, texture, size, color, smell, and so forth. When he brings the wax towards a flame, these characteristics change completely. However, it seems that it is still the same thing: it is still the same piece of wax, even though the data of the senses inform him that all of its characteristics are different. Therefore, in order to properly grasp the nature of the wax, he should put aside the senses. He must use his mind. Descartes concludes:

In this manner, Descartes proceeds to construct a system of knowledge, discarding perception as unreliable and instead admitting only deduction as a method. In the third and fifth ''Meditation'', he offers an ontological proof of a benevolent God (through both the ontological argument and trademark argument). Because God is benevolent, he can have some faith in the account of reality his senses provide him, for God has provided him with a working mind and sensory system and does not desire to deceive him. From this supposition, however, he finally establishes the possibility of acquiring knowledge about the world based on deduction ''and'' perception. In terms of epistemology therefore, he can be said to have contributed such ideas as a rigorous conception of foundationalism and the possibility that reason is the only reliable method of attaining knowledge. He, nevertheless, was very much aware that experimentation was necessary in order to verify and validate theories.

Descartes also wrote a response to skepticism about the existence of the external world. He argues that sensory perceptions come to him involuntarily, and are not willed by him. They are external to his senses, and according to Descartes, this is evidence of the existence of something outside of his mind, and thus, an external world. Descartes goes on to show that the things in the external world are material by arguing that God would not deceive him as to the ideas that are being transmitted, and that God has given him the "propensity" to believe that such ideas are caused by material things.

Dualism[link]

Descartes in his Passions of the Soul and The Description of the Human Body suggested that the body works like a machine, that it has material properties. The mind (or soul), on the other hand, was described as a nonmaterial and does not follow the laws of nature. Descartes argued that the mind interacts with the body at the pineal gland. This form of dualism or duality proposes that the mind controls the body, but that the body can also influence the otherwise rational mind, such as when people act out of passion. Most of the previous accounts of the relationship between mind and body had been uni-directional.

Descartes suggested that the pineal gland is "the seat of the soul" for several reasons. First, the soul is unitary, and unlike many areas of the brain the pineal gland appeared to be unitary (though subsequent microscopic inspection has revealed it is formed of two hemispheres). Second, Descartes observed that the pineal gland was located near the ventricles. He believed the cerebrospinal fluid of the ventricles acted through the nerves to control the body, and that the pineal gland influenced this process. Cartesian dualism set the agenda for philosophical discussion of the mind–body problem for many years after Descartes's death.

Although Descartes realized that both humans and animals have pineal glands (see ''Passions of the Soul'' Part One, Section 50, AT 369), he believed that ''only humans have minds''. This led him to the belief that animals cannot feel pain, and Descartes's practice of vivisection (the dissection of live animals) became widely used throughout Europe until the Enlightenment.

Descartes' moral philosophy[link]

For Descartes, Morals was a science, the highest and most perfect of them, and like the rest of sciences had its roots in Metaphysics. In this way he argues for the existence of God, investigates the place of men in nature, formulates the theory of mind-body dualism and defends free will. But, he being a convinced rationalist, clearly estates that Reason suffices us in the search for the goods we should seek, and for him, virtue consists in the correct reasoning that should guide our actions. Nevertheless, the quality of this reasoning depends on knowledge, as a well informed mind will be more capable of making good choices, and also on mental condition. For this reason he said that a complete moral philosophy should include the study of the body. He discussed this subject in the correspondence with Princess Elisabeth of Bohemia, and as a result wrote his work ''The Passions of the Soul'', that contains a study of the psychosomatic processes and reactions in man, with an emphasis on emotions or passions.

Men should seek the sovereign good that Descartes, following Zeno, identifies with virtue, as this produces a solid blessedness or pleasure. For Epicurus the sovereign good was pleasure, and Descartes says that in fact this is not in contradiction with Zeno's teaching, because virtue produces a spiritual pleasure, that is better than bodily pleasure. Regarding Aristotle opinion that happiness depends on the goods of fortune, Descartes does not deny that this goods contribute to happiness, but remarks that they are in great proportion outside our control, whereas our mind is under our complete control.

The moral writings of Descartes came at the last part of his life, but earlier, in his ''Discourse on Method'' he adopted three maxims to be able to act while he put all his ideas into doubt. This is known as his "Provisional Morals".

Historical impact[link]

Emancipation from Church doctrine[link]

Descartes has been often dubbed as the father of modern Western philosophy, the philosopher that with his sceptic approach has profoundly changed the course of Western philosophy and set the basis for modernity. The first two of his ''Meditations on First Philosophy'', those that formulate the famous methodic doubt, are the portion of Descartes writings that most influenced modern thinking. It has been argued that Descartes himself didn't realize the extent of his revolutionary gesture. In shifting the debate from "what is true" to "of what can I be certain?," Descartes shifted the authoritative guarantor of truth from God to Man (While traditional concept of "truth" implies an external authority, "certainty" instead relies on the judgement of the individual Man). In an anthropocentric revolution, Man is now raised to the level of a subject, an agent, an emancipated being equipped with autonomous reason. This is a revolutionary step which posed the basis of modernity (whose repercussion are still ongoing): the emancipation of man from Christian revelational truth and Church doctrine, a man that makes his own law and takes its own stand. In modernity, the guarantor of truth is not God anymore but Man, a "self-conscious shaper and guarantor" of his reality. Man in this way is turned into a reasoning adult, a subject and agent, as opposed to a child obedient to God. This change in perspective was characteristic of the shift from the Christian mediaval period to the modern period, it had been anticipated in other fields and now Descartes was giving it a formulation in the field of philosophy.

This anthropocentric perspective, establishing human reason as autonomous, posed the basis for the Enlightenment's emancipation from God and the Church. It also posed the basis for all subsequent anthropology. Descartes philosophical revolution is sometimes said to have sparked modern anthropocentrism and subjectivism.

Mathematical legacy[link]

One of Descartes' most enduring legacies was his development of Cartesian or analytic geometry, which uses algebra to describe geometry. He "invented the convention of representing unknowns in equations by ''x'', ''y'', and ''z'', and knowns by ''a'', ''b'', and ''c''". He also "pioneered the standard notation" that uses superscripts to show the powers or exponents, for example the 4 used in x⁴ to indicate squaring of squaring. Descartes’ work provided the basis for the calculus developed by Newton and Leibniz, who applied infinitesimal calculus to the tangent line problem, thus permitting the evolution of that branch of modern mathematics.

Descartes' rule of signs is also a commonly used method to determine the number of positive and negative roots of a polynomial.

Descartes discovered an early form of the law of conservation of mechanical momentum (a measure of the motion of an object). He outlined his views on the universe in his Principles of Philosophy.

Descartes also made contributions to the field of optics. He showed by using geometric construction and the law of refraction (also known as Descartes's law or more commonly Snell's law, who discovered it 16 years earlier) that the angular radius of a rainbow is 42 degrees (i.e., the angle subtended at the eye by the edge of the rainbow and the ray passing from the sun through the rainbow's centre is 42°). He also independently discovered the law of reflection, and his essay on optics was the first published mention of this law.

Contemporary reception[link]

Although Descartes was well known in academic circles towards the end of his life, the teaching of his works in schools was controversial. Henri de Roy (Henricus Regius, 1598–1679), Professor of Medicine at the University of Utrecht, was condemned by the Rector of the University, Gijsbert Voet (Voetius), for teaching Descartes's physics.

Bos found the letter mentioned in a summary of autographs kept by Haverford College in Haverford, Pennsylvania. The College was unaware that the letter had never been published. This was the third letter by Descartes found in the last 25 years.

Mark Steel (born 4 July 1960) is an English socialist columnist, author and comedian. A stand-up comedian known for his left-wing beliefs (he was a long-standing member of the Socialist Workers Party before he resigned in 2007), he has made many appearances on radio and television shows as a guest panellist, and has written regular columns in printed media. He is perhaps best known for presenting ''The Mark Steel Lectures'', ''The Mark Steel Revolution'', ''The Mark Steel Solution'', and ''Mark Steel's in Town''.

Early life[link]

Steel was adopted a few days after he was born. He grew up in Swanley, Kent. He was expelled from Swanley Comprehensive School for attending a cricket course at the age of 15, and went on to work in a garage. From there he went on to make his first public performance as a poet.

In the late 1970s his father suffered a mental breakdown and was placed into care at Stonehouse Hospital. The shabby conditions of the home reinforced Steel's political beliefs.

Career[link]

Steel has given varying accounts of his early life: he became bored with constantly being asked how he had started in comedy and took to telling the questioner the first thing that came into his head. He is often described as having worked as a television repair man but confesses that he has no technical ability whatsoever. He worked the comedy circuit for several years, and then in 1992 presented a satirical radio show ''The Mark Steel Solution'' on BBC Radio 5, consisting of half-hour monologues which offered solutions to social problems. It ran to four series. ''It's Not a Runner Bean'', a comic autobiography, was published in 1996, and this led to a column in ''The Guardian''.

Steel wrote a column for ''The Guardian'' between 1996 and 1999. He was sacked by that newspaper, according to him because ''The Guardian'' wanted to "realign towards Tony Blair" - though ''The Guardian'' denies this. In 2000 he started writing a weekly column for ''The Independent'', which appears in the Wednesday Opinion Column.

He has written and performed several radio and television series for the BBC, and authored several books, as detailed below.

In 2005 he toured the UK and Ireland, where he discussed the French revolution in a light-hearted style.

Personal life[link]

Steel is a supporter of Crystal Palace F.C. and Kent County Cricket Club and enjoys watching both play on occasion. He was interviewed by Jonathan Agnew on Test Match Special during the South Africa series, giving an interview on his love of cricket.

He has a son (Elliot) and a daughter (Eloise) from a relationship, but he and his partner separated in 2006.

Politics[link]

During the Thatcher years, when he was in his 20s, Steel developed his left-wing political views. His anger and frustration at society's injustices were vented by political protests, punk rock and poetry.

Seeing the Soviet Union as "shit", and state capitalist rather than truly socialist, Steel joined the Socialist Workers Party rather than the Communist Party. He attended marches, strikes and demonstrations, and was present at the death of Blair Peach. In the early '80s he also persuaded his mother to allow striking steelworkers to spend a night in the Steel residence. His political activism continued throughout the decade, from the miners' strike through to the Poll Tax Riots. During this time he moved into a squat with his old friend Mick Hannan, before taking up residence in a flat.

In 2000 Steel took part in the London Assembly elections on behalf of the London Socialist Alliance (part of the Socialist Alliance) in the Croydon and Sutton constituency; he received 1,823 votes (1.5 per cent of the vote).

In 2007 he left the SWP and justified his decision in his book ''What's Going On?'' In the book he wrote that he left the party because whilst the membership base had become smaller and smaller, the members that remained became increasingly deluded regarding the size and relevance of the organisation. He also condemned the manner in which, at a time when there was broad public support for socialist ideals, increasingly bitter and futile in-fighting on the left made political success impossible. Alex Callinicos, International Secretary of the SWP, reviewed the book in the ''Socialist Review'', arguing that it "evinces a kind of grandiose ignorance" and that "the only principle one can detect here is that the SWP is always in the wrong". Literary critic Nicholas Lezard praised the book in ''The Guardian'', particularly for its discussion of the break-up of Steel's relationship, which "gives it a poignancy and depth which at its outset one might not have expected".

Steel is a Palestinian human rights activist, having been a member of the British-based ENOUGH! coalition that seeks to end the "Israeli occupation of the Gaza Strip and West Bank."

John Cottingham is an English philosopher, educated at Merchant Taylors’ School near London, and St John’s College, Oxford. He is a Professor Emeritus of Philosophy, University of Reading, Professorial Research Fellow, Heythrop College, University of London, Honorary Fellow of St John’s College, Oxford and editor of Ratio: the International Journal of Analytic Philosophy. The focus of his research has been early-modern philosophy (Rene Descartes was the subject of his DPhil at Oxford), the philosophy of religion and moral philosophy. Cottingham has served as a president of the Aristotelian Society, the British Society for the Philosophy of Religion, the Mind Association and as Chairman of the British Society for the History of Philosophy. A Festschrift with responses by Cottingam, ''The Moral Life'', was published by Palgrave in 2008.

Descartes[link]

In his work on Descartes, Cottingham introduced trialism as an alternative interpretation of the mind-body dualism of Descartes. Although composed of two substances, mind and body, the human being possesses distinctive attributes in its own right (including sensations, passions, emotions), and these form a third category, that cannot be reduced to thought or extension. Cottingham has also argued that Descartes’s view of animals as ‘machines’ does not have the reductionistic implications commonly supposed. Finally, Cottingham has explored the importance of Descartes as a moral philosopher, with a comprehensive picture of the good life that draws both on his scientific work (in physiology and psychology) and also on the theistic outlook that informs all his philosophy. Cottingham is co-editor and translator of the three-volume Cambridge edition of The Philosophical Writings of Descartes.

Moral philosophy and philosophy of religion[link]

In Philosophy and the Good Life and other works Cottingham criticizes the psychological impoverishment of contemporary moral philosophy, and argues that any plausible theory of a good and integrated life for human beings needs to draw on the insights available from a broadly psychoanalytic perspective. His work on partiality defends the importance of self-concern as a central ingredient in virtue. In On the Meaning of Life, he addresses the relationship between moral, aesthetic and religious modes of awareness in constituting a meaningful life. Cottingham’s more recent work in the philosophy of religion argues for the primacy of the moral and spiritual aspects of religious allegiance over theoretical and doctrinal components.
