In , Descartes began to compose Rules for the Direction of the Mind , a short treatise outlining a new method of thought. By using a set of rational principles, Descartes had been able to eliminate many of his own doubts about fundamental ideas. Although the book was originally intended to be composed of three sections of twelve rules, Descartes only completed the first twelve. These first twelve deal with simple propositions. Descartes hoped to show that even these problems could be expressed through mathematics.

In , the Inquisition issued a formal condemnation of the work of the Italian scientist Galileo. He argued, contrary to the traditional notion that Earth was the center of the universe, that Earth revolves around the sun. Galileo was condemned to death for heresy, but his sentence was later reduced to house arrest. At the time, Descartes was working on The World , a study he thought would revolutionize the study of physics. Discourse on the Method relates the series of revelations Descartes had in while in the stove-heated room in Germany.
After confessing how he came to doubt all his knowledge, Descartes shows how he used his rules to solve profound problems.

The Discourse was meant to serve as an introduction to three essays Descartes had been laboring over— Optics , Meteorology, and Geometry— which contain science now regarded obsolete. Here Descartes addresses the concerns and attempted refutations various readers sent to him after reading the Discourse. Meditations was followed by Principles of Philosophy , which attempts to reduce the universe to its mathematical foundation. By the time Principles was widely read in Europe, Descartes was the toast of continental intellectual circles and was awarded a pension by the king of France.
But as his fame grew, so did the demands on his time. Lack of sleep and inhospitable living conditions took their toll on Descartes, and, in , he died of pneumonia at age fifty-four.

More often, however, they just ignore him. But the seventeenth and eighteenth centuries were one of those rare periods when a lot of people cared, because their sense of the world was decomposing so dramatically. Literate people—and, thanks to the printing press, there were more of these than ever before—were eager to hear from philosophers who could give new answers to the ancient questions. If everything you thought you knew was wrong, how could you ever be confident that your knowledge was correct? Where does knowledge come from? What is matter made of? Is there a God, and, if so, what kind of being is he?
These were the questions that animated the philosophers discussed by Gottlieb, starting with Descartes. His areas of expertise, in addition to mathematics, included optics, physiology, and meteorology. This rumor was a fitting one, since Descartes argued for a thoroughly mechanistic view of nature. Descartes abolished this distinction, holding, instead, that everything physical that exists is simply matter in space. They appear to human beings because of the way our sensory apparatus is constructed, but they are not inherent in the things themselves.
Another way of putting this is that Descartes described reality in terms of qualities that can be measured mathematically. Descartes himself was a towering mathematician, but he was far from the first philosopher to regard mathematics as the gold standard of truth: Pythagoras and Plato had done so two thousand years before.
In the dialogue known as the Meno, Plato depicts Socrates teaching a slave boy the Pythagorean theorem—or, rather, leading the boy to figure it out for himself. The dialogue shows what is so seductive about mathematics, that each step follows inevitably from the previous step, in a way that makes it absolutely beyond doubt or error.
To Plato, this could be explained by the fact that the soul had a life before birth in which it learned mathematical truths, so that learning is really a form of remembering. Descartes had no use for such a tale, which raised far more questions than it answered. Begin, Descartes wrote, by doubting absolutely everything you know, think, and perceive; assume that it is all delusive, as in a dream.
Does anything remain absolutely certain, even after this purge?

One thing does, he argued: the fact of my consciousness. If I think, I must exist— Cogito ergo sum. From this fixed basis, Descartes believed that he could infallibly deduce another crucial principle: the existence of a good God, who guarantees the truth of my perceptions and so underwrites the existence of the world. But here most people believe that Descartes went astray. Indeed, Descartes never found a satisfying solution to the problem of how mind and matter interact.
He famously identified the pineal gland as the point of connection, though how a gland could have access to an immaterial mind is far from clear. Gottlieb observes that Descartes would have been disappointed to know that he gave rise to a whole new era of philosophy. He thought that there would not have to be any philosophy after him, since he had solved all the problems; only experimental research would remain. Some of the answers that the best minds of the period came up with may now appear bizarre.

If the world nonetheless appears to be a chain of causes and effects, that is because the monads are programmed to behave in such a way that they seem to be interacting. Even today, cognitive scientists struggle to understand how consciousness arises from matter, though few doubt that it does.
In each case, theory denies that the world as it appears is the fundamental reality, and looks to something more original to explain it. To answer the questions that philosophy asks, a long detour through science is necessary; but at the beginning and the end of the journey we find the same sense of wonder. Certainly, both Descartes and Leibniz relied on God to balance the equation of the universe. Without him, they believed, the world did not make sense. But Baruch Spinoza, another revolutionary thinker of the seventeenth century, went furthest in reconceiving the idea of God, in ways so radical that his name became a byword for dangerous atheism.
Instead, Spinoza made God so crucial to the world that the distinction between the two collapsed. There could not be two substances in the universe, Spinoza argued, one physical and the other divine, since this involved a logical contradiction. If God and Nature were distinct, then it must be the case that Nature had some qualities that God lacked, and the idea of a supreme being lacking anything was incoherent. It follows that God and Nature are just two names for the same thing, the Being that comprises everything that ever existed or ever will exist.
This radical idea, known as pantheism, has strange and paradoxical results. On the one hand, it divinizes the universe, meaning that it brings God very close to us—indeed, it says that we ourselves are part of God. On the other hand, an immanent God is not the kind of God who watches over the world, hears prayers, and punishes sinners.
He was also much bolder than other philosophers in stating what many of them surely believed, that the Bible was a human document that contained no privileged information about historical events or the nature of divinity. It should therefore be read and studied like any other book, with due attention to the motives of its authors and the errors that had crept in throughout years of transmission. This secular, rational approach to Scripture made Spinoza arguably the father of Biblical criticism. After all, if everything is God, and God is absolute, then there is no way that anything could happen differently from the way it does.
But he wanted to go even further. Each person had the right to decide what God was and how best to serve him.
https://agendapop.cl/wp-content/numbers/nes-gps-espia.php Taken together, these beliefs give Spinoza a claim to be considered the first great philosopher of liberal democracy. Where Descartes and Spinoza tried to come to grips with reality through purely deductive logic, the conventional story goes, Locke and Hume valued the evidence of the senses.

Their empiricism is often taken to be a peculiarly British kind of virtue, defining a difference between British and Continental philosophy that persists to this day: on the one hand, skepticism of knowledge that has no basis in experience and experiment; on the other, outlandish theories based on unrestrained ratiocination.
