500:"Thus what I thought I had seen with my eyes, I actually grasped solely with the faculty of judgment, which is in my mind." In this manner, Descartes proceeds to construct a system of knowledge, discarding perception as unreliable and instead admitting only deduction as a method. Halfway through the Meditations, he also claims to prove the existence of a benevolent God, who, being benevolent, has provided him with a working mind and sensory system, and who cannot desire to deceive him, and thus, finally, he establishes the possibility of acquiring knowledge about the world based on deduction and perception.

flame, these characteristics change completely. However, it seems that it is still the same thing: it is still a piece of wax, even though the data of the senses inform him that all of its characteristics are different. Therefore, in order to properly grasp the nature of the wax, he cannot use the senses: he must use his mind. Descartes concludes:

Often regarded as the first "modern" thinker for providing a philosophical framework for the natural sciences as these began to develop, Descartes in his
Meditations on First Philosophy attempts to arrive at a fundamental set of principles that one can know as true without any doubt. To achieve this,

Descartes' method of hyperbolic doubt was a means to foundationalism with the goal of certainty. In logic, this method may be used to determine the soundness of an argument; however, as
Cartesian doubt, Descartes fails to necessitate the premises of his "clear and distinct idea" thesis. This thesis,

Descartes's theory provided the basis for the calculus of Newton and
Leibniz, and thus for much of modern mathematics. This appears even more astounding when one keeps in mind that the work was just meant as an example to his Discours de la méthode pour bien conduire sa raison, et chercher la verité

To further demonstrate the limitations of the senses, Descartes proceeds with what is known as the Wax
Argument. He considers a piece of wax: his senses inform him that it has certain characteristics, such as shape, texture, size, color, smell, and so forth. However, when he brings the wax towards a

Descartes of the utmost importance for his discovery of analytic geometry. Up to Descartes's times, geometry, dealing with lines and shapes, and algebra, dealing with numbers, appeared as completely different subsets of mathematics. Descartes showed how to translate many

Therefore, Descartes concludes that he can be certain that he exists. But in what form? You perceive your body through the use of the senses; however, these have previously proved unreliable. So
Descartes concludes that at this point, he can only say that he is a thinking thing. Thinking is his

Initially, Descartes arrives at only a single principle: if I am being deceived, then surely "I" must exist. Most famously, this is known as cogito ergo sum, ("I think, therefore I am"). (These words do not appear in the

He gives the example of dreaming: in a dream, one's senses perceive things that seem real, but do not actually exist. (This idea is similar to what Chuang Tzu writes after dreaming that he is a butterfly.) Thus, one cannot rely on the data of the senses as necessarily true. Or, perhaps an "evil

Cartesian doubt results in solipsism, the idea that we may be the only thing in the universe. When
Kierkegaard comes up against solipsism he develops inwardness as characteristic of the self. His concern with the role of the self in the organization of experience gives us foundational
