A brief biography of Descartes: René Descartes was born near Tours, France. He received his education from Jesuit Collège Royale in La Flèche. Descartes was allowed to stay in bed due to his ill-health until late morning and he formed the habit of meditation. From the age of 16, he concentrated on studying mathematics. However, a breach of 4 years was created in his study since he went to volunteer in Europe's Thirty Years War as a volunteer. During this time, he felt the urge of philosophical calling and focused on this after leaving the army. He spent most of his time in Netherlands and Paris. In 1649, he was invited to Sweden by Queen Christiana with a view to discussing philosophy. There he was expected to get up quite early in the morning. Descartes understood that this new regim of his routine and the Swedish climate caused pneumonia of which he died a year later. https://drive.google.com/file/d/1MJ7fT9cCqRYk76_i_w3bJkVZjRvVQLja/view?usp=drivesdk (link for Descartes's d...
