Example text

But I may not even understand the concept of a molecule (as most people before the nineteenth century did not), let alone believe that the sun is made up of them. Knowledge is not closed under entailment. But (a) adds a K operator to the second conjunct. If I know that the sun is a star and know that the sun being a star entails that it is made up of molecules, then I know that the sun is made up of molecules. If Nozick's argument needed only (b) as a premise, it would be a sound argument, but since it needs (a) it seems unsound.

How do we know whether the possibility of a mule being painted to look like a zebra is relevant to picking out zebras? If I believe in demons who intervene in human affairs, does the possibility of a demon causing these animals to look like zebras become a relevant alternative? This leads to a second problem. 2. Contextualism relativizes knowledge in a way that may be unduly subjective. What you know may depend on whether or not you have certain background beliefs. I may be said to know that the zebra in front of us is truly a zebra because I can just barely distinguish it from painted mules and because I don't believe in demons.

In order to meet condition (4), we must be able to make relevant discriminations. 52 CHAPTER 3 Modern Skepticism According to this theory, conditions (3) and (4) take the place of the standard condition that S must be justified in believing p (see chapter 5). Since knowledge is defined as truth-tracking, it only matters whether the belief in question is true, would not have been believed if it weren't true, and would remain true in slightly altered circumstances. The question arises: What would lead Nozick to say that you can know p and know p g, but not know q?
