§2.2
Once you are confident that you have found an argument, you need to identify its premises and conclusion. In order to recognize that a passage contains an argument in the first place, you must have already noticed that at least one proposition is intended either to support or to be supported by another. Thus, you will have already identified either a conclusion or a premise. Now you need to identify any remaining premises or conclusions that there may be. In doing this keep in mind that they may be introduced with inferential particles, but that they needn’t be.
The argument may be presented in any order. For example, each of the sentences expresses the same argument as the map on the right.
(i) Alcohol should be illegal, because it’s a drug and all drugs should be illegal.
(ii) Alcohol is a drug, and all drugs should be illegal, so alcohol should be.
(iii) All drugs should be illegal, so alcohol should be, since it’s a drug.
