有人同史密斯講瓊斯有一輛福特車，佢亦都相信呢件事，所以有理由相信：“一係瓊斯有一輪福特車，一係布朗喺巴塞羅那”——雖然史密斯根本唔知道布朗喺邊。但事實上，瓊斯係冇福特車，但係布朗又的確喺巴塞羅那，所以史密斯相信嘅事係真嘅（符合真信念），於是呢件事就得到咗證成。但瓊斯有冇福特車同布朗喺唔喺巴塞羅那呢兩件事根本冇關係，所以唔係知識 。
Someone told Smith that Jones had a Ford, and he believed in it, so there was reason to believe that either Jones had a Ford for a while, or Brown was in Barcelona — even though Smith had no idea where Brown was. But the fact that Jones didn't own a Ford, but Brown was in Barcelona, so what Smith believed was true (in line with his true belief), so it was proven. But Jones has nothing to do with whether or not there is a Ford and Brown is not in Barcelona at all, so not knowledge.
