Unformatted text preview: 1091001notesWeek9 © 1 Dr Mc’s Philosophy 001 (1091) Lecture Notes, Week 9 © Arguments and Testimony We often rely on the words of others when deciding what to believe. That is, we accept a statement on the basis of somebody else’s “testimony”. This is often okay! Can you imagine what it would be like not to take anybody’s word for anything? -You’d have to open a can of soup before you bought it, just to see if it had in it what the label said. -You’d have to go to foreign countries to learn anything about them. -You would have to create your own measuring instruments. Language is important to us in part because it allows us to transmit information. What we should be concerned with is whether the case we are considering is one in which testimony is not good evidence. There are two main ways in which testimony plays a role. 1) in testimonial arguments 2) in support of premises of non-testimonial arguments. 1) Testimonial arguments.

P (is true). 1091001notesWeek9 © 2 Now, this is much better than pattern #1. Following this pattern will lead to trouble much less often. However, what about that person at work, who is always going on about stuff he knows nothing about... Standard Pattern #3 for Testimonial Arguments: 1. S said that P is true. 2. S was sincere in saying that P is true. 3. S is knowledgeable about the subject matter of P. 4. Usually, when someone sincerely says P, and is knowledgeable about the subject matter of P, P is true....
