Document Summary
When considering whether an argument"s premise is true, we need to consider whether its source is reliable. If it is not, then it would be unreasonable to accept the premise. Some sources of evidence are very trustworthy, and others are not. If the source of the evidence is not trustworthy, then the evidence will not be acceptable: imagine that you are on a jury and that jones has been charged with murder. Suppose that smith testifies that jones was at the murder scene. We can think of this testimony as a premise in an argument for the conclusions that jones is the murderer. The prosecutor is offering that testimony as a reason to believe that jones is guilty. As a member of the jury, you need to assess that argument. As we have seen, there are really only two questions you need to answer. Observation, measurement, and testimony are among our most reliable sources of evidence.
