Professor: One cannot frame an accurate conception of one' s physical environment on the basis of a single momentary perception, since each such glimpse occurs from only one particular perspective. Similarly, any history book gives only a distorted view of the past, since it reflects the biases and prejudices of its author. The professor's argument proceeds by ["making a case for the conclusion of one argument by showing that argument's resemblance to another, presumably cogent, argument", 'attempting to show that one piece of reasoning is incorrect by comparing it with another, presumably flawed, piece of reasoning', 'arguing that because something has a certain group of characteristics, it must also have another, closely related, characteristic', 'arguing that a type of human cognition is unreliable in one instance because it has been shown to be unreliable under similar circumstances']
