  • Skepticism is a topic of interest in philosophy, particularly epistemology, but can be applied to any topic, such as politics, religion, or pseudoscience.

  • Philosophical skepticism is a prominent form of skepticism that rejects knowledge claims that seem certain from the perspective of common sense. Some forms of it even deny that one knows that "I have two hands" or that "the sun will come out tomorrow".

  • Skepticism has been responsible for important developments in various fields, such as science, medicine, and philosophy. In science, the skeptical attitude toward traditional opinions was a key factor in the development of the scientific method.

  • Ancient skepticism arose both in ancient Greece and India, and two major schools of skepticism in the ancient Greek and Roman world were Pyrrhonism and Academic Skepticism.

  • Religious skepticism can be seen as a form of skepticism that doubts religious doctrines, and some Catholic writers, including Francisco Sanches, Michel de Montaigne, and Pierre Gassendi, deployed ancient skeptical arguments to defend moderate forms of skepticism and to argue that faith, rather than reason, must be the primary guide to truth.

  • Skepticism is related to various terms such as agnosticism, relativism, dogmatism, blind faith, and credulity.
