《知识问题》的主题是哲学的怀疑主义,它的原因和治疗。艾耶尔指出,哲学家对知识的可能性曾经提出了若干问题。他认为第一个问题是在“探索确实性”的情况下产生的。他说,哲学家假定除非一个陈述是无可怀疑的,它就不能被认识到是真的,于是就寻找一些完全确实和“无可怀疑”的东西起 The theme of “knowledge problems” is philosophical skepticism, its causes and treatment. Ayer pointed out that philosophers raised a number of questions about the possibility of knowledge. He believes that the first question arises in the context of “exploration of certainty.” He said that the philosopher assumed that unless a statement was beyond doubt, it could not be realized as true, and thus sought something completely and “undoubtedly”
