Early Life and Education
Rene Descartes was born on 31 March 1596 in La Haye en Touraine in France, a town later renamed Descartes in his honor. His father, Joachim Descartes, served as a magistrate, and his mother, Jeanne Brochard, died when he was very young. Frail health in childhood earned him indulgence for late rising, a habit that he would keep through much of his life. He studied at the newly established Jesuit College of La Fleche from 1607, where the rigorous curriculum of the Ratio Studiorum exposed him to mathematics, classical literature, and scholastic philosophy derived from Aristotle and Thomas Aquinas. The discipline and clarity of mathematics impressed him even as he grew dissatisfied with the limits of scholasticism. After La Fleche he studied law at the University of Poitiers, receiving a licentiate in 1616, a practical credential that he never used in a legal career.

Formative Travels and First Writings
In 1618 Descartes traveled to the Dutch Republic and associated with military circles at Breda, where he met the Dutch scholar Isaac Beeckman. Beeckman became an early and important interlocutor, encouraging Descartes to tackle problems in mathematics and physics. Descartes wrote the Compendium of Music and began formulating methodological reflections that would later define his philosophy. A period of travel followed, including time in Germany and the Holy Roman Empire. During the winter of 1619 he described a chain of insights that convinced him he had discovered a new way of inquiry grounded in method rather than authority. These experiences prepared him for a life devoted to reforming knowledge by beginning from first principles.

Building a Life in the Dutch Republic
From 1628 he settled largely in the Dutch Republic, valuing its relative intellectual freedom and the possibility of working quietly. He moved among cities such as Amsterdam and Leiden, living modestly and writing. He maintained a far-reaching correspondence, especially with Marin Mersenne in Paris, who acted as a hub of the European Republic of Letters. Through Mersenne, Descartes engaged with a wide range of contemporaries and critics, including Thomas Hobbes, Pierre Gassendi, and Antoine Arnauld. He composed a treatise on the cosmos, Le Monde, but when he learned of the condemnation of Galileo Galilei in 1633, he withheld it from publication, wary of offending religious authorities.

Method and Metaphysics
Descartes presented his mature method in the Discourse on the Method (1637), published in French to reach a broader audience. He proposed beginning inquiry by doubting all that could be doubted, retaining only what could withstand the most radical scrutiny. From this he arrived at his famous conclusion: that the act of thinking itself guarantees the existence of the thinker. This provided a foundation for rebuilding knowledge with clarity and distinctness as the hallmark of truth. He developed his metaphysics most fully in the Meditations on First Philosophy (1641), written in Latin and circulated with critical objections solicited by Mersenne. In them he argued for the existence of God and defended the real distinction between mind and body. His dualism made the mind an immaterial thinking substance and the body an extended, mechanistic substance. The exchange of letters with Princess Elisabeth of Bohemia pressed him to clarify how mind and body interact, a problem he located in the human composite and, speculatively, in the pineal gland.

Mathematics and Natural Philosophy
Descartes transformed mathematics by uniting algebra and geometry. In La Geometrie, one of three scientific essays appended to the Discourse in 1637, he showed how to represent curves by equations and solve geometric problems using algebraic methods. The coordinate system that places points by pairs of numbers became known as Cartesian coordinates, and his notational practice helped standardize the use of x, y, and z for unknowns. He also contributed to optics in La Dioptrique, describing the law of refraction (often called Snell's law) with a mechanical derivation and explaining phenomena such as the rainbow. In Les Meteores, he offered corpuscular explanations of weather and atmospheric effects. His Principles of Philosophy (1644) provided a systematic presentation of his physics and metaphysics, proposing a universe filled with matter in motion whose vortices accounted for celestial phenomena. Although later developments would supplant parts of his physics, the ambition to explain nature by clear mechanical principles was decisive for early modern science.

Correspondence, Critics, and Influence
The Meditations appeared with sets of Objections and Replies gathered from leading thinkers. Hobbes objected to Descartes's account of substance and knowledge; Gassendi pressed empiricist critiques; Arnauld tested the coherence of clear and distinct perception. Descartes answered them all, refining his arguments. He also engaged, sometimes sharply, with Pierre de Fermat on problems in geometry and optics. Through Mersenne, his ideas circulated widely, reaching Benedict Spinoza and Gottfried Wilhelm Leibniz in the next generation, both of whom adapted and transformed his project. The exchanges with Princess Elisabeth deepened the European discussion of the passions and moral life; Descartes's own account appeared in The Passions of the Soul (1649), which linked physiology, psychology, and ethics. His views, especially on the mechanistic nature of animals as automata and on the human passions, provoked debate among physicians, theologians, and philosophers.

Final Years
Late in life Descartes accepted an invitation from Queen Christina of Sweden to come to Stockholm to advise on scholarly matters and conduct lessons in philosophy. He arrived in 1649 and found court life demanding, with lessons scheduled in the cold early mornings. On 11 February 1650 he died in Stockholm, commonly said to be from pneumonia. His death ended a career lived largely in deliberate seclusion, punctuated by intense correspondence and carefully staged publications. His remains were later transferred to France, reflecting the national pride that grew around his reputation.

Legacy
Descartes reshaped philosophy by offering a new starting point for certainty and by insisting on methodical clarity. His cogito became a touchstone for debates about self, knowledge, and skepticism. His dualism defined the mind-body problem for centuries, and his interactionist account inspired both critique and development from figures like Elisabeth of Bohemia and, later, Malebranche and Leibniz. In mathematics, analytic geometry changed the landscape of problem solving and prepared the way for calculus. In natural philosophy, even where his specific theories were superseded, his effort to explain nature without appeal to occult qualities fostered the mechanistic approach that helped make modern science possible. Through friends and critics alike, especially Marin Mersenne, Isaac Beeckman, Hobbes, Gassendi, Arnauld, Princess Elisabeth, Queen Christina, and rivals such as Fermat, Descartes worked in and helped to create a European conversation that shaped modern thought. He remains one of the central architects of the early modern transformation of philosophy and science.
