How Is Certainty Possible?
Certainty is defined as being free of doubt. In philosophy is there such a thing that we know without any doubt? Do we know anything with absolute certainty? Although we may believe to have genuine knowledge in some cases, there are other cases in which we do not know, but only think we know. Now therein lies the problem, how do we distinguish what is absolutely certain and what is not? This is why the idea of knowledge and certainty is so important. Both empiricists and rationalists have attempted to determine this.

When you know something you not only have an opinion, but that opinion is true. Now how do we distinguish which opinions are true. We cant just say because we believe something, it is true. Although everything we know is also believed, not everything we believe is known. A person can believe something is true but in fact he can be wrong about it. Take a weather man for example he can believe that it will rain or not rain tomorrow and then in fact be wrong. However, if he were to say that its either going to rain or not rain tomorrow, he wouldnt be wrong. There is no way he can be proven wrong. However we learn nothing from this. This is why it is so difficult to determine what is certain in the world. In fact many philosophers believe we cannot

say anything is certain in the world. So what can we know with absolute certainty? Perhaps only that I exist, and some mathematical, logical self evident truths.

Then came Descartes, who like many others, tried to apply mathematics to philosophy in order to find certainty. In order to disprove skepticism, Descartes decided to use skepticism. He would out-doubt skeptics by doubting everything he had ever believed until he arrived at something that could not be doubted. While doubting everything he believed he also found a way to doubt the empiricists view, the view that knowledge comes from the senses. His first reason for doubt is the common experience of being deceived by the senses. People sometimes suffer from delusions, such as the insane and those on drugs. Other instances in which the senses mislead us are mirages, deliriums, and delusions stemming from fever. For these people what reality seems to them is not real at all. Another ground for doubt is that, while sleeping, we dream. While dreaming we believe what is happening is real when in fact its not. It is only upon waking that we can tell the difference between the real world and the dream world. How can we be sure that we are not in fact in a dream world at this moment? Its sort of like the Matrix. In the movie the main character is in a dream world his entire life up until others come to free him. If it werent for them he wouldve been in that dream world his entire life and would not have known the difference. In trying to achieve certainty, Descartes tried to establish something that cannot be doubted. It then occurs to him that the act of doubting itself is the answer he was looking for. Doubting is a form of mental activity, a form of thinking. Even if we are unsure of what we are, where we are and the world around us, there is not doubt that we are thinking. Even if we are deceived by our senses, even if we are dreaming we are still thinking. From the fact that we think, we can conclude that we exist. “I think, therefore I am.”-Descartes

In contrast to Descartes rational views on knowledge was the empiricists view. What could be more obvious than the view that the senses are the only dependable source of knowledge? “Seeing is believing,” as we would say. Empiricists argue that there is nothing in the mind that was not previously
