SKEPTICISM, in philosophy, is a critical
attitude or methodology that questions the claim of knowledge made
by philosophers and others. Skepticism has been known in various
degrees, including the refusal to acknowledge that any knowledge is
possible at all, the denial that any knowledge is valid if it is
not derived from sense experience, and the denial of claims of
knowledge in specific fields such as metaphysics, theology, or the
sciences. Skepticism has contributed to the advancement of
epistemology, or theories of knowledge, by forcing the critical
analysis of all claims to knowledge and the rejection of
unwarranted assumptions.
在哲学中，怀疑论是质疑哲学家和其他人提出的知识主张的一种批判态度或方法。人们对怀疑论已有不同程度的了解，包括拒绝承认任何知识是可能的，如果它不是源自感觉经验，便否认任何知识是有效的，并且否认在特定领域中的知识主张，诸如形而上学、神学，或科学。怀疑论通过对所有的知识主张和拒绝接受无根据假设的强制批判分析，促进了认识论，或知识理论的进步。
