Skepticism or scepticism (see American and British English spelling differences) is generally any questioning attitude towards knowledge, facts, or opinions/beliefs stated as facts,[1] or doubt regarding claims that are taken for granted elsewhere.[2]
Philosophical skepticism is an overall approach that requires all information to be well supported by evidence.[3] Classical philosophical skepticism derives from the 'Skeptikoi', a school who "asserted nothing".[4] Adherents of Pyrrhonism, for instance, suspend judgment in investigations.[5] Skeptics may even doubt the reliability of their own senses.[6] Religious skepticism, on the other hand, is "doubt concerning basic religious principles (such as immortality, providence, and revelation)".[7]

Definition
In ordinary usage, skepticism (US) or scepticism (UK) (Greek: 'σκέπτομαι' skeptomai, to think, to look about, to consider; see also spelling differences) refers to:
- (a) an attitude of doubt or a disposition to incredulity either in general or toward a particular object;
- (b) the doctrine that true knowledge or knowledge in a particular area is uncertain; or
- (c) the method of suspended judgment, systematic doubt, or criticism that is characteristic of skeptics (Merriam–Webster).
In philosophy, skepticism refers more specifically to any one of several propositions. These include propositions about:
- (a) an inquiry,
- (b) a method of obtaining knowledge through systematic doubt and continual testing,
- (c) the arbitrariness, relativity, or subjectivity of moral values,
- (d) the limitations of knowledge,
- (e) a method of intellectual caution and suspended judgment.
Philosophical skepticism
Main article: Philosophical skepticism
In philosophical skepticism, pyrrhonism is a position that refrains from making truth claims. A philosophical skeptic does not claim that truth is impossible (which would be a truth claim), instead it recommends "suspending belief". The label is commonly used to describe philosophies which appear similar to philosophical skepticism, such as academic skepticism, an ancient variant of Platonism that claimed knowledge of truth was impossible. Empiricism is a closely related, but not identical, position to philosophical skepticism. Empiricists see empiricism as a pragmatic compromise between philosophical skepticism and nomothetic science; philosophical skepticism is in turn sometimes referred to as "radical empiricism."
Western Philosophical skepticism originated in ancient Greek philosophy.[8] The Greek Sophists of the 5th century BC were partially skeptics.
Pyrrho of Elis (365-275 BC) is usually credited with founding the "school" of skepticism. He traveled to India and studied with the "gymnosophists" (naked lovers of wisdom), which could have been any number of Indian sects. From there, he brought back the idea that nothing can be known for certain. The senses are easily fooled, and reason follows too easily our desires.[9] Pyrrhonism was a school of skepticism founded by his follower Aenesidemus in the first century BC and recorded by Sextus Empiricus in the late 2nd century or early 3rd century AD. Subsequently, in the "New Academy" Arcesilaus (c. 315-241 BC) and Carneades (c. 213-129 BC) developed more theoretical perspectives by which conceptions of absolute truth and falsity were refuted as uncertain. Carneades criticized the views of the Dogmatists, especially supporters of Stoicism, asserting that absolute certainty of knowledge is impossible. Sextus Empiricus (c. AD 200), the main authority for Greek skepticism, developed the position further, incorporating aspects of empiricism into the basis for asserting knowledge.
Greek skeptics criticized the Stoics, accusing them of dogmatism. For the skeptics, the logical mode of argument was untenable, as it relied on propositions which could not be said to be either true or false without relying on further propositions. This was the regress argument, whereby every proposition must rely on other propositions in order to maintain its validity (see the five tropes of Agrippa the Sceptic). In addition, the skeptics argued that two propositions could not rely on each other, as this would create a circular argument (as p implies q and q implies p). For the skeptics, such logic was thus an inadequate measure of truth and could create as many problems as it claimed to have solved. Truth was not, however, necessarily unobtainable, but rather an idea which did not yet exist in a pure form. Although skepticism was accused of denying the possibility of truth, in fact it appears to have mainly been a critical school which merely claimed that logicians had not discovered truth.
In Islamic philosophy, skepticism was established by Al-Ghazali (1058–1111), known in the West as "Algazel", as part of the Ash'ari school of Islamic theology, whose method of skepticism shares many similarities with Descartes' method.[10]
In an effort to avoid skepticism, René Descartes begins his Meditations attempting to find indubitable truth on which to base his knowledge. He later recognizes this truth as "I think, therefore I am," but before he finds this truth, he briefly entertains the skeptical arguments from dreaming and radical deception.
David Hume has also been described as a global skeptic.
Pierre Le Morvan (2011) has distinguished between three broad philosophical approaches to skepticism. The first he calls the "Foil Approach." According to this approach, skepticism is treated as a problem to be solved, or challenge to be met, or threat to be parried; skepticism's value on this view, insofar as it is deemed to have one, accrues from its role as a foil contrastively illuminating what is required for knowledge and justified belief. The second he calls the "Bypass Approach" according to which skepticism is bypassed as a central concern of epistemology. Le Morvan advocates a third approach—he dubs it the "Health Approach"—that explores when skepticism is healthy and when it is not, or when it is virtuous and when it is vicious.
Scientific skepticism
Main article: Scientific skepticism
A scientific (or empirical) skeptic is one who questions beliefs on the basis of scientific understanding. Most scientists, being scientific skeptics, test the reliability of certain kinds of claims by subjecting them to a systematic investigation using some form of the scientific method.[11] As a result, a number of claims are considered "pseudoscience" if they are found to improperly apply or ignore the fundamental aspects of the scientific method. Scientific skepticism may discard beliefs pertaining to things outside perceivable observation and thus outside the realm of systematic, empirical falsifiability/testability.

Religious skepticism
Main article: Religious skepticism
Religious skepticism generally refers to doubting given religious beliefs or claims. Historically, religious skepticism can be traced back to Socrates, who doubted many religious claims of the time. Modern religious skepticism typically places more emphasis on scientific and historical methods or evidence, with Michael Shermer writing that it is a process for discovering the truth rather than blanket non-acceptance. For this reason, a religious skeptic, while believing that Jesus existed may question the claims of being the messiah or performing miracles (see historicity of Jesus). Religious skepticism is not the same as atheism or agnosticism, though these often do involve skeptical attitudes toward religion and philosophical theology (for example, towards divine omnipotence). Religious people are generally skeptical about claims of other religions, at least when the two denominations conflict in some stated belief. In addition, they may also be skeptical of the claims made by atheists.[12] The historian Will Durant writes that Plato was "as skeptical of atheism as of any other dogma."[13]
