True skeptics are not really doubters. The word skepticism in Greek is skepsis which along these lines implies that inquisitive minds  have been hypothesizing and pondering since the time of the Ancient Greeks. Skeptics utilize motivation to elucidate their musings and thoughts to propel their arguments (Unger, 198). The concept of the skeptic is essential to understand, because on the grounds of the true skeptic, they are inseparably unique in relation to the the pure rejecter, who transparently rejects all evidence opposite their own point of view. In terms of skepticism, skeptics set a particular standard for reasoning in which to approach in various positions in argument. The skeptical attitudes displayed by skeptics have been the impetus for the creative and evolutionary ideas presented in arguments defending those positions. 
In defending the skeptic, the external world is in opposition to our awareness. The vast majority of what we accept or find in the world, originates from our encounters. Some philosophers, like Huemer, theorize that our beliefs and ideas come from experience.  We frequently believe hat the origins of our experiences are material objects. The presence of such objects is basically in the external world. One of the fundamental attributes of the outside world is that it lives autonomously of any event whatsoever (Huemer, 195). That is, for instance, if a winged animal had existence in the external world, at that point it would exist whether it was being seen or not. In any case, if the flying creature exists just in the event that somebody comprehended that it existed, at that point it is absent in the outside world. People make an association between something being genuine and inside the head. Dreams are just ideas that exist inside the head. Saying dreams exists, does not deny the experience as functional, or that the explanations behind the experience are sensible. For it being inside your head, rejects the criticalness that it exists openly of the experience. At the point when an individual quits having a specific dream, the dream does not continue existing inside someone else. Ordinarily, objects differentiate from what is inside our heads (Huemer, 200). They exist outside of the head like the external world .The three arguments made by Huemer try to state the stance of the skeptic. Mike Huemer represents in his beginning two premises that humans lack recognition of extraneous subjects and the last thesis examines a moderate stance that discusses the lack of external items in the world.
