Possibility of Knowledge and Tides of Skepticism in Western Classical Philosophy

The problem of the possibility of knowledge is one of the main issues in epistemology, which dates back to the beginning of philosophy. In this regard, some Western philosophers, have embarked to solve the problem by presupposing the possibility of knowledge, some others by accepting the claims posed by skeptics, still some others by appealing to theology and again some others, through a new explanation of objectivity which has led to deepening the gap between the subject and the object, and have, thus, supported one of its two aspects. All these viewpoints are based on the assumption of contrast between the subject and the object and definition of knowledge as something in which no error is admitted; more over, they are deprived of any philosophical reasonings in favor of the possibility of knowledge, and have bore no results but tides of skepticism.
