Etymologically, the skeptic is the researcher or the one who asks the questions. One who predisposes others to hear the answers or expresses doubt.
The term skeptic is often used in a different and stronger sense from the philosophers. It could mean a person who denies the possibility of knowing anything. In such a situation, skepticism will be a doctrine that expresses such negation.
Knowledge is unattainable.
The term skepticism should be distinguished from the term fallibilism. It is one thing to say that we can confuse at every turn, it is quite another to say that under no circumstances could we know anything.
The problem of skepticism is central to Western philosophy in its modern period and remains controversial among contemporary philosophers.
Some semioticians suggest that a balance of knowledge in explicit semiotic terms would point the way between the Scylla of Skepticism and the Charybdis of Dogmatism.
