Document Summary

Deductive strength: the definition of deductive strength. When figuring out an argument is deductively valid, upon evaluating the premises, if you find that you are justified in believing it"s true, then it"s a good argument and you should accept the conclusion. Successful arguments of this sort are deductively strong. An argument must satisfy 2 things to be deductively strong: must be deductively valid, all its premises must be justified (or reasonable) Arguments can have premises that are reasonable for one person to believe but not reasonable for another. The strength of an argument can vary from person to person: comments on the definition of deductive strength. Just as your evidence for a statement can vary over time, the rational status of a premise, and thus the strength of an argument, can vary over time. The second way an argument can be weak is for it to have a premise about which you should suspend judgement.
