In like manner, a true belief cannot be called knowledge when it is deduced by a fallacious process of reasoning, even if the premises from which it is deduced are true. If I know that all Greeks are men and that Socrates was a man, and I infer that Socrates was a Greek, I cannot be said to “know” that Socrates was a Greek, because, although my premises and my conclusion are true, the conclusion does not follow from the premises.
