Socrates raises the question comparing knowledge with true opinion and at first, it seems that knowledge is no more valuable than true opinion (or true belief without justification) because we can suppose that a subject S that knows how to drive to her friend’s house because she was there before can get there in the same way as another subject Z that don’t know where her friend’s house is (i.e. , does not have a true belief justified) but has a true belief about her friend’s house location.
