 Here is a Gettier case (adapted from Zagzebski 1996: 285–6). Mary enters the house and looks into the living room. A familiar appearance greets her from her husband’s chair. She thinks, “My husband is sitting in the living room”, and then walks into the den. But Mary misidentified the man in the chair. It is not her husband, but his brother, whom she had no reason to believe was even in the country. However, her husband was seated along the opposite wall of the living room, out of Mary’s sight, dozing in a different chair.
