Skepticism (or scepticism) has many definitions, but generally refers to any questioning attitude of knowledge, facts, or opinions/beliefs stated as facts, or doubt regarding claims that are taken for granted elsewhere. The word may characterise a position on a single matter, as in the case of religious skepticism, which is "doubt concerning basic religious principles (such as immortality, providence, and revelation)", but philosophical skepticism is an overall approach that requires all new information to be well supported by evidence. Skeptics may even doubt the reliability of their own senses. Classical philosophical skepticism derives from the 'Skeptikoi', a school who "asserted nothing". Adherents of Pyrrhonism, for instance, suspend judgment in investigations.
In philosophy, skepticism refers more specifically to any one of several propositions. These include propositions about:
Philosophical skepticism originated in ancient Greek philosophy. The Greek Sophists of the 5th century BC were for the most part skeptics. Pyrrhonism was a school of skepticism founded by Aenesidemus in the first century BC and recorded by Sextus Empiricus in the late 2nd century or early 3rd century AD. One of its first proponents was Pyrrho of Elis (c. 360-275 B.C.), who traveled and studied as far as India and propounded the adoption of "practical" skepticism. Subsequently, in the "New Academy" Arcesilaus (c. 315-241 B.C.) and Carneades (c. 213-129 B.C.) 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. A.D. 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 orthodox Ash'ari school of Islamic theology, whose method of skepticism shares many similarities with Descartes' method.
René Descartes is credited for developing a global skepticism as a thought experiment in his attempt to find absolute certainty on which to base the foundation of his philosophy. Descartes discussed skeptical arguments from dreaming and radical deception. David Hume has also been described as a global skeptic. However, Descartes was not ostensibly a skeptic and developed his theory of an absolute certainty to disprove other skeptics who argued that there is no certainty.

Michael Brant Shermer (born September 8, 1954) is an American science writer, historian of science, founder of The Skeptics Society, and Editor in Chief of its magazine ''Skeptic'', which is largely devoted to investigating pseudoscientific and supernatural claims. The Skeptics Society currently has over 55,000 members. Shermer also engages in debates on topics pertaining to pseudoscience and religion, in which he promulgates the need for scientific skepticism, expresses his views on those topics from that perspective.
Shermer is also the producer and co-host of the 13-hour Fox Family (now ABC Family) television series ''Exploring the Unknown''. Since April 2001, he has been a monthly columnist for ''Scientific American'' magazine with his Skeptic column. Shermer states he was once a fundamentalist Christian, but converted from a belief in God during his graduate studies, and has described himself as an agnostic, nontheist, atheist and advocate for humanist philosophy as well as the science of morality. He has expressed reservations about such labels, however, as he sees them being used in the service of 'pigeonholing,' and prefers to simply be called a skeptic.
Shermer's graduate studies in experimental psychology at California State University, Fullerton, led to many after-class discussions with professors Bayard Brattstrom and Meg White, which is when his "Christian ichthys got away, and with it my religion." Shermer completed his master's degree from California State University in experimental psychology in 1978. Shermer began competitive bicycling in 1979, and spent a decade in the sport. During the course of his cycling, Shermer worked with cycling technologists in developing better products for the sport. During his association with Bell Helmets, a bicycle-race sponsor, Shermer advised them on design issues regarding their development of expanded-polystyrene for use in cycling helmets, which would absorb impact far better than the old leather "hairnet" helmets used by bicyclists for decades. Shermer advised them that if their helmets looked too much like motorcycle helmets, in which polystyrene was already being used, and not like the old hairnet helmets, that no serious cyclists or amateur would use them. This suggestion led to their first model, the ''V1 Pro'', which looked like a black leather hairnet, but functioned on the inside like a motorcycle helmet. In 1982, Shermer worked with Dr. Wayman Spence, whose small supply company, Spenco Medical, adapted the gel technology Spence developed for bedridden patients with pressure sores into cycling gloves and saddles to alleviate the carpal tunnel syndrome and saddle sores suffered by cyclists.
During the decade in which he raced long distances, he helped to found the 3,000-mile nonstop transcontinental bicycle Race Across America (along with Lon Haldeman and John Marino), in which he competed five times (1982, 1983, 1984, 1985, 1989), was assistant race director six years, and executive race director seven years. An acute medical condition is named for him: "Shermer's neck" is pain in and extreme weakness of the neck muscles found among long-distance bicyclists. Shermer suffered the condition during the 1983 Race Across America. Shermer's embrace of scientific skepticism crystallized during his time as a cyclist, explaining, "I became a skeptic on Saturday, August 6, 1983, on the long climbing road to Loveland Pass, Colorado" after months of training under the guidance of a "nutritionist" with an unaccredited Ph.D. After years of practicing acupuncture, chiropractic, massage therapy, negative ions, rolfing, pyramid power, fundamentalist Christianity, and "a host of weird things" (with the exception of drugs) to improve his life and training, Shermer stopped rationalizing the failure of these practices. Shermer would later produce several documentaries on cycling.
Shermer earned his Ph.D. at Claremont Graduate University in history of science in 1991 (with his dissertation titled "Heretic-Scientist: Alfred Russel Wallace and the Evolution of Man: A Study on the Nature of Historical Change"). Shermer later based a full-length, 2002 book on his dissertation: ''In Darwin's Shadow: The Life and Science of Alfred Russel Wallace: A Biographical Study on the Psychology of History''.
Before starting the Skeptics Society, Shermer was a professor of the history of science at Occidental College, California. Since 2007, Shermer has been an adjunct professor at Claremont Graduate University.
In 1992 Shermer started the Skeptics Society, which produces ''Skeptic'' magazine and currently has over 55,000 members. In addition, the group organizes the Caltech Lecture Series which offers speakers on a wide range of topics relating to science, psychology, social issues, religion/atheism, skepticism, etc. Past speakers include Stephen Jay Gould, Jared Diamond, Donald Johanson, Julia Sweeney, Richard Dawkins, Philip Zimbardo, Steven Pinker, Carol Tavris, David Baltimore, Lisa Randall, Daniel Dennett, Tim Flannery, Lawrence Krauss, Michio Kaku, Susan Blackmore, Christof Koch, Alison Gopnik, Ursula Goodenough, Edward Tufte, Bjorn Lomborg, Sam Harris, Jeff Schweitzer and many others. The lectures occur on Sunday afternoons, and are open to the public for a nominal fee.
In ''How We Believe: The Search for God in an Age of Science'', Shermer explored the psychology behind the belief in God. In its introduction Shermer wrote "Never in history have so many, and such a high percentage of the population, believed in God. Not only is God not dead as Nietzsche proclaimed, but he has never been more alive."
In early 2002, Shermer's ''Scientific American'' column introduced Shermer's Last Law, the notion that "any sufficiently advanced extraterrestrial intelligence is indistinguishable from God." Shermer's Last Law is a spin on Clarke's Third Law.
In 2002, Shermer and Alex Grobman wrote their book ''Denying History: Who Says the Holocaust Never Happened and Why Do They Say It?'' which examined and refuted the Holocaust denial movement. This book recounts meeting various denialists and concludes that free speech is the best way to deal with pseudohistory.
''Science Friction: Where the Known Meets the Unknown'' was released in 2005. Then his 2006 book ''Why Darwin Matters: The Case Against Intelligent Design'', marshals point-by-point arguments supporting evolution, sharply criticizing Intelligent Design. This book also argues that science cannot invalidate religion, and that Christians and conservatives can and should accept evolution.
In June 2006, Shermer, who formerly expressed skepticism regarding the mainstream scientific view on global warming, wrote that, in view of the accumulation of evidence, the position of denying global warming is no longer tenable.
''The Mind of The Market: Compassionate Apes, Competitive Humans, and Other Tales from Evolutionary Economics'' was released in 2007. In it Shermer reports on the findings of multiple behavioral and biochemical studies that address evolutionary explanations for modern behavior.
In February 2009, Shermer published ''The History of Science: A Sweeping Visage of Science and its History'', a 25-hour audio lecture.
In May 2011, Shermer published ''The Believing Brain: From Ghosts and Gods to Politics and Conspiracies---How We Construct Beliefs and Reinforce Them as Truths''.
Shermer appeared as a guest on ''Donahue'' in 1994 to respond to Bradley Smith's and David Cole's Holocaust denial claims, and in 1995 on ''The Oprah Winfrey Show'' to challenge Rosemary Altea's psychic claims. Shermer made a guest appearance in a 2004 episode of Penn & Teller's ''Bullshit!'', in which he argued that events in the Bible constitute "mythic storytelling," rather than events described literally. His stance was supported by the show's hosts, who have expressed their own atheism. The episode in question, ''The Bible: Fact or Fiction?'', sought to debunk the notion that the Bible is an empirically reliable historical record. Opposing Shermer was Paul Maier, professor of ancient history at Western Michigan University.
Shermer made several appearances on NBC's daytime paranormal-themed show ''The Other Side'' in 1994 and 1995. After getting to know that show's producers, he made a formal pitch to their production company for his own skepticism-oriented reality show whose aim would be to present points of view of both believers and skeptics. His proposals were not fruitful, but several years later, one of the executives of that company went to work for the then-newly formed Fox Family Channel, and impressed with Shermer's show treatment, requested he pitch it to the network. The network picked up the series, ''Exploring the Unknown'', of which Shermer became a producer and cohost. The series, which was budgeted at approximately $200,000USD per episode, was viewed by Shermer as a direct extension of the work done at the Skeptics Society and ''Skeptic'' magazine, and would enable Shermer to reach more people. The equivocal title was chosen so as to not tip off guests or viewers as to the skeptical nature of the show. Various segments from ''Exploring the Unknown'' can be found on Shermer's YouTube channel.
Shermer has been a speaker at all three Beyond Belief events from 2006 to 2008. He also spoke at the 2006 TED Conference on "Why people believe strange things."
Shermer is a frequent guest on ''Skepticality'', the official podcast of ''Skeptic''.
On August 21, 2010, Dr. Shermer was honored with an award recognizing his contributions in the skeptical field, from The IIG during its 10th Anniversary Gala.
Politically, Shermer has described himself as a libertarian.
