CRITICISM ON DESCARTES’ FIRST ARGUMENT FOR SKEPTICISM In his First Meditation, Descartes argues that beliefs based on the senses are to be doubted of their factuality, and because all of our beliefs are based on our senses, everything we believe we know is doubtful, therefore, not knowledge. To support this argument, Descartes suggests two premises; the ‘Dream Argument’ and the ‘Evil Demon Argument’. First, the ‘Dream Argument’ states that all we perceive to be reality may be just a dream, and because there is no way of finding out whether we are dreaming or not, everything we know may be false illusions. The concept of a ‘dream’ can also be understood as an ‘illusion’, or the ‘result of our imaginations’. In this sense, the statement, at first glance may seem true, because although illusions and imaginations conjure up the most bizarre and impossible things which obviously cannot not exist in the so-called ‘reality’, we conceive them to be real while we are dreaming. For example, I may be going through a dream (nightmare) as I write this bizarrely and impossibly difficult assignment. However, no matter how improbable it may be that such an assignment exists, or at least, is given to me, I am still writing it, because the situation seems all too real for me to suppose it is a dream. I can never know for sure whether I am actually tapping on my laptop or sleeping in a laboratory with wires plugged into my brain. As such, most dreams cannot be distinguished from reality, and this possibility makes every moment of reality dubitable. One possible refutation against this is that even our dreams and imaginations must be based on something real, as in the case of mermaids, which are a fusion of fish and women, and unicorns, of horses and horned-creatures. Even if such ‘real’ things(fish, women, horses, horned-creatures) were all creations of the mind, at least the
