" Though we now know through experience that fire can burn us and water can drown us, Hume suggests that we should try to rid ourselves of the ignorance that pertains to what is the relationship between cause and effect. He accurately points out that anytime that we think we truly understand the nature of an object, we are just describing that object with as much detail and precision as we have accessible to us. This idea is interesting because it leads one to question whether our most valuable truths in science are in fact, viable. .
Hume's arguments about gathering information from the outer world objects are contradicting against Descartes certain and necessary truths. Our senses, reason and imagination are innate concepts that were stored in our mind according to him. Descartes indicates that he cannot be deceived into thinking that he does not exist when in fact he does, if something have existed there would be nothing to be wrong when we have selected all truths coming from the senses and the imagination and many of those which come from understanding. So, he has found one truth which he can know with absolute certainty. In the wax example Descartes indicates that the concept of wax does not change even after it melted. His main argument is that the awake and asleep modes that we have contain the same particular actions in real and in dreams. If are sitting in front of the window in our dream while sleeping in the bed, the image is different from reality but two plus two is still four even while we are asleep. Sciences as such geometry and mathematics are certain and indubitable for Descartes. .
In science classes, instructors stress the importance of determining causation. The modern scientific method allows for many ways to describe every imaginable characteristic of something. These descriptions lead to more rigorous testing and further detailed descriptions. When finding these descriptions, a scientist knows that what they are doing is describing an object or event.
