2.1 The Truth Condition

“The earth is motionless at the center of the universe.” This statement would be plausible to a Medieval audience but is not plausible to a modern audience.

A premise can be plausible to a given audience and still be false.

The persuasive power of an argument is a function of the subjective plausibility of its premises for a given audience, not a function of the actual truth of the premises.

If an argument has false premises, the argument is necessarily a bad one, regardless of the subjective plausibility of the premises for a given audience.

“Cell phone usage is a leading cause of brain cancer”. Can this statement can be (objectively) true for some audiences but (objectively) false for others?
