To identify the warrantWarrant of an argument, we identify the content expressions common to the argument. We identify the widest content expressions. If a content expression contains another as a proper part, it is a wider content expression. In extracting the warrantWarrant of an argument we replace shared content expressions with either variables or schematic letters. Some warrantsWarrant indicate that a conclusionConclusion follows without exception, while others may indicate that the conclusionConclusion follows only tentatively. In some cases, identifying the warrantWarrantof an argument is straightforward. Other cases may be challenging. We analyze several challenging examples. In addition, some arguments have unstated premisesPremise (or conclusionsConclusion) and it may be necessary to recognize them to extract the warrantWarrant properly. If an argument involves several steps, as in a divergent or serial argumentSerial argument, a warrantWarrant corresponds to each step.
