In “Elusive Knowledge”, Lewis begins by saying that we know a lot of trite information about the ordinary world. I know what carrots are. I know how to drive a car. I know that when someone greets me and holds out their hand, they expect me to shake it and so on. However, when we talk in philosophical terms about knowledge, we have no reason to say that we really know anything. There seem to be two contexts of knowing something. Regarding the everyday, general type of knowledge, I know a lot. But when I put on my philosopher’s hat, it looks like I can’t say I really know very much at all. As a result, it is argued that either we know lots of things, or we must submit to skepticism. (first paragraph)
