Does certainty distinguish knowledge from mere belief? What is knowledge? Plato’s definition of knowledge; a justified, true belief on a subject. Bearing this definition, a knowledge not only has to be justified with enough evidences, it has to always be true, and believed to be true. Then the problem with this definition is the small extent of certainty. What does it mean to have ‘enough evidence’? To what extent can we know the truth of something in the past, present and especially, future? Is believing irrational and will not guide us to the truth? Does lacking certainty makes something untrue? If we become critical of the things we claim to know, it is easy to wonder if we know anything for certain. However, even if we say something is untrue, does it make it unuseful? In order to analyze this issue, I will bring up examples from the Natural and Human Sciences.
However before that, I will define some keywords that will be essential in my approach. I have defined accepted as gaining the approval of society and authority, discarded as being completely rejected or forgotten, today as being the present and tomorrow the future. Now, considering the first issue raised by the statement; to what extent is the statement correct in depicting the nature of science in general? I find it as a rather pessimistic view of the nature of scientific theories. It may be true that the history of science shows that many of what we considered as mature knowledge 100 years ago were to a certain extent false. We are currently using some theories that didn’t exist back then. If we view our present theories as correct- just as people 100 years ago viewed theirs, we can almost logically deduce that, since the theories are different and our theories are c...

...ute truth. If we were to consider the extreme implication, there won’t be any pursuit of knowledge. If one takes this perspective and holds the pessimism of it, their solution is no solution at all.
In conclusion, I can see that the statement depicts the reality of natural and human science, however it does poorly exhibit that science has generally been a successful endeavor empirically and structurally, and how knowledge we have today is useful and beneficial. From this essay, we can see that there have been times when knowledge have been “discarded,” but that doesn’t mean future investigations and expeditions will not result in knowledge. May knowledge actually be untrue, doesn’t necessarily mean that it doesn’t improve anything. As to the pessimisticism depicted by the statement, through elimination, one untrue knowledge means one step closer to a true knowledge.
