史密斯同瓊斯兩個人去競爭一個工作職位，史密斯喺某個夜晚聽到人哋講上司會將呢個職位畀瓊斯。事實上瓊斯比佢學歷高，經驗亦都更優勝，所以佢好有理由相信瓊斯會得到呢個職位。同時史密斯聽講瓊斯中咗彩票。於是史密斯就認識到：“得到呢個職位嘅人係中咗彩票”。但最後，史密斯得到咗呢個職位，而且史密斯唔知道嘅事仲有：佢自己買嘅彩票都中咗獎。所以出現咗嘅問題係：雖然史密斯好明確噉證成咗“得到呢個職位嘅人中咗彩票”，而且係一個得到辯護嘅真信念，但佢係咪真係知道呢件事呢？
Smith and Jones compete for a job position, and one night Smith hears that his boss will give Jones the position. In fact, Jones is more educated and experienced than him, so he has reason to believe that Jones will get the position. At the same time, Smith heard that Jones had won the lottery. So Smith realized that a wisp of people who got the position had won the lottery. But in the end, Smith got the position, and there was one more thing Smith didn't know: he had won the lottery tickets he bought. So the question that arises is: while Smith has made it clear that the person who got the position won the lottery, and that it was a true belief that was defended, did he really know about it?
