  • Epistemology is concerned with the nature of knowledge and justified belief. What is knowledge? Can we have any knowledge at all? Can we have knowledge about the laws of nature, the laws or morality, or the existence of other minds? The view that we can’t have knowledge is called skepticism. An extreme form of skepticism denies that we can have any knowledge whatsoever. But we might grant that we can have knowledge about some things and remain skeptics concerning other issues. Many people, for instance, are not skeptics about scientific knowledge, but are skeptics when it comes to knowledge of morality. Later in this course we will entertain some skeptical worries about science and we will consider whether ethics is really in a more precarious position. Some critical attention reveals that scientific knowledge and moral knowledge face many of the same skeptical challenges and share some similar resources in addressing those challenges. Many of the popular reasons for being more skeptical about morality than science turn on philosophical confusions we will address and attempt to clear up.

    Even if we lack absolute and certain knowledge of many things, our beliefs about those things might yet be more or less reasonable or more or less likely to be true given the limited evidence we have. Epistemology is also concerned with what it is for a belief to be rationally justified. Even if we can’t have certain knowledge of anything (or much), questions about what we ought to believe remain relevant.
