Childhood Born prematurely on April 5,when his mother heard of the coming invasion of the Spanish Armada a fleet of Spanish warshipsThomas Hobbes later reported that "my mother gave birth to twins: After being involved in a fight with another clergyman outside his own church, the elder Thomas Hobbes was forced to flee to London, England, leaving his wife, two boys and a girl behind.
In Discourse on the MethodDescartes recalls, 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.
Given his ambition to become a professional military officer, inDescartes joined, as a mercenarythe Protestant Dutch States Army in Breda under the command of Maurice of Nassau and undertook a formal study of military engineeringas established by Simon Stevin. Descartes, therefore, received much encouragement in Breda to advance his knowledge of mathematics.
Together they worked on free fallcatenaryconic sectionand fluid statics. Both believed that it was necessary to create a method that thoroughly linked mathematics and physics. Martin's Daywhile stationed in Neuburg an der DonauDescartes shut himself in a room with an "oven" probably a Kachelofen or masonry heater to escape the cold.
While within, he had three dreams  and believed that a divine spirit revealed to him a new philosophy.
However, it is likely that what Descartes considered to be his second dream was actually an episode of exploding head syndrome.
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 discovered this basic truth quite soon: He visited Basilica della Santa Casa in Loreto, then visited various countries before returning to France, and during the next few years spent time in Paris.
It was there that he composed his first essay on method: Descartes returned to the Dutch Republic in In Amsterdam, he had a relationship with a servant girl, Helena Jans van der Strom, with whom he had a daughter, Francinewho was born in in Deventer. She died of scarlet fever at the age of 5.
Unlike many moralists of the time, Descartes was not devoid of passions but rather defended them; he wept upon Francine's death in Nevertheless, in he published part of this work  in three essays: The first was never to accept anything for true which I did not clearly know to be such; that is to say, carefully to avoid precipitancy and prejudice, and to comprise nothing more in my judgment than what was presented to my mind so clearly and distinctly as to exclude all ground of doubt.
In he published a metaphysics work, Meditationes de Prima Philosophia Meditations on First Philosophywritten in Latin and thus addressed to the learned. InCartesian philosophy was condemned at the University of Utrecht, and Descartes was obliged to flee to the Hague, and settled in Egmond-Binnen.
Descartes began through Alfonso Polloti, an Italian general in Dutch service a long correspondence with Princess Elisabeth of Bohemiadevoted mainly to moral and psychological subjects.
This edition Descartes also dedicated to Princess Elisabeth. In the preface to the French editionDescartes 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.
She was interested in and stimulated Descartes to publish the " Passions of the Soul ", a work based on his correspondence with Princess Elisabeth.
There, Chanut and Descartes made observations with a Torricellian barometer, a tube with mercury. Challenging Blaise PascalDescartes took the first set of barometric readings in Stockholm to see if atmospheric pressure could be used in forecasting the weather.
Soon it became clear they did not like each other; she did not like his mechanical philosophynor did he appreciate her interest in Ancient Greek.
By 15 JanuaryDescartes had seen Christina only four or five times. On 1 February he contracted pneumonia and died on 11 February. Pies, a German scholar, published a book questioning this account, based on a letter by Johann van Wullen, who had been sent by Christina to treat him, something Descartes refused, and more arguments against its veracity have been raised since.
His manuscripts came into the possession of Claude ClerselierChanut's brother-in-law, and "a devout Catholic who has begun the process of turning Descartes into a saint by cutting, adding and publishing his letters selectively. Cartesianism Initially, Descartes arrives at only a single first principle: 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: 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. 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 the person is immediately conscious.René Descartes's Influences. BACK; NEXT ; Check out the books, authors, and Big Ideas that influenced this critic.
