The Skepticism is a philosophical position which holds that the possibility of knowledge is limited either because of the limitations of the mind, that is every mind has of understanding reality or because the inaccessibility of its objects, like the metaphysical realities. It is related to questioning attitude of human beings. It held this position because of the diversity of contradictory views held in philosophy.And these diverse views raise serious doubt whether humans have ability to reach an objective universal truth. Secondly, that each mind has its way of understanding reality and hence no one is qualified to prove that my view is better or correct than the view of the other. Thirdly, we make mistakes and yet we think that we are right. However, there is a possibility that we are wrong all the time.
In ancient Greece, the sophists provide their argument based on skepticism. The modern skepticism is associated with Hume, and J.S.Mill. It is reaction against dogmatic metaphysics and is the logical consequence of a through – going empiricism. Descartes introduced the method of doubt, which has influenced the western philosophy significantly. He considered doubt is the source of knowledge. To doubt was not an end in itself; it was a process of purification, of eliminating various false hoods, and of ultimately arriving at an unshakable foundations of truth. In fact, our doubt implies the reality of our thoughts. Doubting means thinking, this implies a self consciousness. Cogito ergo sum (I think therefore I am).Descartes regarded it as primary truth of reason. For Locke, skepticism was not an end in itself; it was prelude to a more scientific philosophy. Though out the western philosophy, one form or other skepticism has becomes one of its features. In fact, Western philosophy has progressed further with skepticism.
