Rene Descartes was once out to determine how he sorted things out and how he knew them as either right or wrong. In his experiment, Descartes decided to use the following two mediations
i. He decided that he should not examine his beliefs as this may take longer due to the extensive nature of the brain and so he decide that he should only examine the very foundation of the beliefs like whether he trusted his sensory beliefs, physics belief, mathematics belief, comprehensive belief and the rest.
ii. In his second mediation, Descartes decided to reject the slightest possibility that a belief is false and he decided not to throw away the suspected false belief but to use it as a candidate for knowledge.
Having concluded his mediations, this greatest thinker decided to apply his two methods using the following three ways.
a) Descartes believed that sometimes human senses are deceptive. This is true that at certain moments our senses can deceive us. For example we might find ourselves looking for something small that is very close to us at a very far distance. Moreover, a tall building from a long distance always looks very small but in real sense the building does not change its size but the sense of our eyes do. Descartes also uses the example of refraction in physics. He argues that our senses lie to us in that if a stick or a ruler is placed in water it looks bent but in actual sense the stick or the ruler are straight. Descartes further argues that this is the basis behind hallucinations and for this reason our senses manufacture a lot of deception. Take the example of staring too much in the sun and then look at the object. It is usually true that the objects color is usually obscured from your senses but later when realized the objects color has not changed at all. Despite all these proof that the senses are deceptive they are usually very reliable when it comes to providing information. So according to Descartes, he decided that use of sensual memory be ruled out when it comes to things that look very small in far distance or under certain abnormal conditions.
b) Descartes also decided to use dream in applying his two mediations. In his argument Descartes to decide to distinguish dream from being awake. Desecrates suggests that when we are dreaming we...
