He has been called the "Father of Modern Philosophy", and much of subsequent Western philosophy can be seen as a response to his writings.
Five of the most important thinkers in the history of Western philosophy. In Descartes went to the university at Franeker, where he stayed with a Catholic family and wrote the first draft of his Meditations.
He matriculated at the University of Leiden in In his Letter to Voetius ofDescartes made a plea for religious tolerance and the rights of man. Claiming to write not only for Christians but also for Turks—meaning Muslims, libertines, infidels, deists, and atheists—he argued that, because Protestants and Catholics worship the same God, both can hope for heaven.
When the controversy became intense, however, Descartes sought the protection of the French ambassador and of his friend Constantijn Huygens —secretary to the stadholder Prince Frederick Henry ruled — Referring to her death, Descartes said that he did not believe that one must refrain from tears to prove oneself a man.
The World and Discourse on Method Injust as he was about to publish The WorldDescartes learned that the Italian astronomer Galileo Galilei — had been condemned in Rome for publishing the view that the Earth revolves around the Sun. Because this Copernican position is central to his cosmology and physics, Descartes suppressed The World, hoping that eventually the church would retract its condemnation.
Although Descartes feared the church, he also hoped that his physics would one day replace that of Aristotle in church doctrine and be taught in Catholic schools. Descartes said that he wrote in French so that all who had good sense, including women, could read his work and learn to think for themselves.
He believed that everyone could tell true from false by the natural light of reason. In three essays accompanying the Discourse, he illustrated his method for utilizing reason in the search for truth in the sciences: In the Discourse he also provided a provisional moral code later presented as final for use while seeking truth: Thus, for Descartes, metaphysics corresponds to the roots of the tree, physics to the trunk, and medicine, mechanics, and morals to the branches.
The second edition includes a response by the Jesuit priest Pierre Bourdin —who Descartes said was a fool. These objections and replies constitute a landmark of cooperative discussion in philosophy and science at a time when dogmatism was the rule. His arguments derive from the skepticism of the Greek philosopher Sextus Empiricus fl.
His beliefs from sensory experience are declared untrustworthy, because such experience is sometimes misleading, as when a square tower appears round from a distance.
Even his beliefs about the objects in his immediate vicinity may be mistaken, because, as he notes, he often has dreams about objects that do not exist, and he has no way of knowing with certainty whether he is dreaming or awake. Nevertheless, it justifies accepting as certain only the existence of the person who thinks it.
On the basis of clear and distinct innate ideasDescartes then establishes that each mind is a mental substance and each body a part of one material substance. The mind or soul is immortal, because it is unextended and cannot be broken into parts, as can extended bodies.
Descartes also advances at least two proofs for the existence of God.

The final proof, presented in the Fifth Meditation, begins with the proposition that Descartes has an innate idea of God as a perfect being. It concludes that God necessarily exists, because, if he did not, he would not be perfect.
Descartes elsewhere argues that, because God is perfect, he does not deceive human beings, and therefore, because God leads us to believe that the material world exists, it does exist. In this way Descartes claims to establish metaphysical foundations for the existence of his own mind, of God, and of the material world.
Thus, in order to show that God exists, Descartes must assume that God exists. He provided understanding of the trunk of the tree of knowledge in The World, Dioptrics, Meteorology, and Geometry, and he established its metaphysical roots in the Meditations.
He then spent the rest of his life working on the branches of mechanics, medicine, and morals. Mechanics is the basis of his physiology and medicine, which in turn is the basis of his moral psychology.
Descartes believed that all material bodies, including the human bodyare machines that operate by mechanical principles.
In his physiological studies, he dissected animal bodies to show how their parts move. He argued that, because animals have no souls, they do not think or feel; thus, vivisectionwhich Descartes practiced, is permitted.
He also described the circulation of the blood but came to the erroneous conclusion that heat in the heart expands the blood, causing its expulsion into the veins.
