First, we need to know about what agnosticism is, I reckon that you might have understood about the skepticism, then I will not discuss it again.
Agnosticism from the greek a, “not” and gignoskos “knowing” a term coined by Thomas Henry Huxley to denote his skeptical view of religion, and now used generally to refer to the attitude and tenets of those who believe that the existence of God cannot be known or proved, and who urge, therefore, a suspension of belief.
In Purpose to arrange the Philosophical Conception, so we need to be able to distinguish between Agnostics and Skeptics, as well as Agnosticism and Skepticism, in order to avoid significant misunderstandings. Whether it’s Agnostic, or Skeptic, both are given the meaning of doubt. The basic difference is, the skeptic places his doubts on the object of knowledge, whereas the doubt of the agnostic lies in the doubts of the knowing subject. Skepticism tends to be an atheist unless the nature of skepticism is used as a method, then doubt is only needed as a method of conducting research, not as a complete and inherent view of a trait. An agnostic attitude is not easy to fall into an atheist, in fact, this attitude instead can make a person low self-esteem which is admirable, since humans have many limitations in knowledge to seeking the truth of knowledge itself. An agnostic attitude is still open in accepting the possibility that occurs, but it is different from a closed attitude which is based on skepticism, where they reject all forms of knowledge because they feel that all these things are impossible to know.
