Skepticism is the process of applying reason and critical thinking to determine validity. It's the process of finding a supported conclusion, not the justification of a preconceived conclusion.
Skepticism ... is generally any questioning attitude towards unempirical knowledge or opinions/beliefs stated as facts, or doubt regarding claims that are taken for granted elsewhere. Skepticism is often separated into categories, related to morality (right or wrong), religion (religious doubt), or the nature of knowledge ("there is no knowledge beyond how things appear.")...
Much of epistemology has arisen either in defense of, or in opposition to, various forms of skepticism. Indeed, one could classify various theories of knowledge by their responses to skepticism. For example, rationalists could be viewed as skeptical about the possibility of empirical knowledge while not being skeptical with regard to a priori knowledge, and empiricists could be seen as skeptical about the possibility of a priori knowledge but not so with regard to empirical knowledge. In addition, views about many traditional philosophical problems, e.g., the problem of other minds or the problem of induction, can be seen as restricted forms of skepticism that hold that we cannot have knowledge of any propositions in some particular domain that is normally thought to be within our ken.
Skepticism ... in Western philosophy, the attitude of doubting knowledge claims set forth in various areas. Skeptics have challenged the adequacy or reliability of these claims by asking what principles they are based upon or what they actually establish.
Philosophical views are typically classed as skeptical when they involve advancing some degree of doubt regarding claims that are elsewhere taken for granted. Varieties of skepticism can be distinguished in two main ways, depending upon the focus and the extent of the doubt.
It means that they have just come into adolescence (physically or mentally)!
That's when the second stage of skepticism, cynicism, self identity, self esteem, disregard for authority etc. start surfacing after the initial childhood stage.
Getting into that stage is almost automatic...but getting out is not so simple. Many people unfortunately, remain in that stage for life without reaching the third stage of maturity.
Humm, wondering who is being the adolescent....
