Document Summary

Arguments: arguments are statements structured in a formal way such that premises support conclusions, statements are claims that are either true or false. Deductive arguments: a deductive argument is either valid or invalid. A valid deductive argument is such that if the premises were true, then the conclusion being supported by those premises would have to be true. An invalid deductive argument is such that even if the premises were true, the conclusion being supported by those premises would not have to be true. An example of a deductive argument: all humans are mortal, socrates is human, therefore, socrates is mortal. If both (1) and (2) were true, then the conclusion, (3), would have to be true: two steps to assessing a deductive argument, step 1 (structure): check for validity. A valid deductive argument is such that if the premises were true, then the conclusion would have to be true.
