The importance of evidence in any pursuit of knowledge is obvious. Having merely true beliefs is typically not sufficient for knowledge. For instance, suppose I guessed that you were born on June 24 and suppose that you were indeed born on June 24. No ordinary understanding of knowledge would consider my correct guess as being knowledge. If I consistently guess right, there might be some use for my talents (and we might even explore deeper just exactly how I am so good at making birthday guesses). But, from an epistemic point of view, my correct guess was just so much sheer luck.
