“We know what we believe” To believe something is to know it, so to know something it is not enough to believe it: you must learn it or have a good reason to believe it. Skepticism speaks of two types of position: knowledge and justification. The skeptic claims that we don't know what we think, what we do is just a thought. Knowledge skepticism claims that there is no such thing as knowledge, and justification denies the existence of justified belief. These two are closely related and depend on the relationship between the factors of knowledge and justification: if knowledge implies justified belief, as theorists say, then skepticism about justification implies skepticism about knowledge. Gettier and Nozick delved into the topic and explained their point of view on the matter. To defend these views, skeptics set out many requirements for knowledge or justified belief and try to show that these requirements are not satisfied. This still holds true, which is why if I know something and believe what I claim to be knowledge, then why do I need a reason to believe it? Is black white? Gettier indicates at the beginning of his selection, that he is concerned with attempts to provide sufficient conditions for someone to know that a proposition is true (Gettier, 43). He is responding to different accounts that a proposition is true, that a person believes that proposition is true, and that the person's justification in belief in the truth of the proposition are jointly sufficient for subjects to know the proposition. Gettier argues that these types, while they may initially seem plausible, are in fact false. A is false because the conditions stated there do not constitute a sufficient condition for the truth of the proposition that S knows that... halfway down the paper... believes it; if it weren't true, he wouldn't believe it. To know p is to be someone who would believe it if it were true, and who would not believe it if it were false (Nozick, 49). Knowledge is of two different types: what we know or where we can go to find the information about it. Awareness of something is sometimes acquired through experience. With knowledge or the thought of knowing something there are many possible and equally equal definitions of knowledge. People saying they know something is a justification for believing it, but the facts could be proven and show that what they believe is not true. It shouldn't be a good reason for someone to say they know these things and believe them. If you know something, you know something. No feedback to test my knowledge. We don't all think or act the same, so knowledge is different for each human being.
