I will begin by explaining the truth condition. This condition is generally unrefuted by epistemologists for how can we know something that is false? We can think we know something and then it turns out we don’t, but that just means we were wrong to think we knew it. For example, it is false that Anne Boleyn was the first president of the United States, and since it is false it is not the sort of thing that everyone knows. There are two refutations to this condition. Firstly, “everyone knew that stress caused ulcers before two Australian doctors in the early 80s proved that ulcers are actually caused by bacterial infection.” (Hazlett) This shows that knowing is not necessarily a factive verb. Secondly, it is possible to know something that is false. For example, Newtonian physics is part of our overall scientific knowledge, if it was false, we would in fact know something false. (Maxwell)
I will now explain the condition of belief. While it seems impossible to know P, without believing that you know P, some philosophers have argued that it is in fact possible. An example of how this is possible was proposed by Colin Radford. Suppose Alfred is
