| | Cumulative (inductive) structures instead accumulate multiple independent reasons that, taken together, make a conclusion probable rather than logically certain. No single reason may be decisive on its own, but the convergence of several distinct lines of evidence increases the overall likelihood that the conclusion is true. This structure is less vulnerable to any one weak point, since the case does not collapse if a single supporting reason is questioned, but its conclusions are correspondingly more provisional and open to degrees of confidence rather than proof. | | Cumulative (inductive) structures instead accumulate multiple independent reasons that, taken together, make a conclusion probable rather than logically certain.

| − | This distinction is especially relevant in [[apologetics]], where the two major traditions tend to favor different structures. [[Presuppositional apologetics]] typically argues in a deductive mode, starting from foundational premises (such as the necessity of a rational, orderly universe) and reasoning to conclusions that are meant to follow necessarily. [[Evidentialist apologetics]] more often argues cumulatively, assembling historical, philosophical, and experiential evidence that, taken together, are presented as making a conclusion highly probable even though no single piece of evidence proves it outright. Recognizing which structure a given argument is using helps a reader evaluate it on its own terms — a deductive argument should be tested by challenging its premises and logical form, while a cumulative argument should be tested by weighing the strength and independence of its converging lines of evidence. | + | This distinction is especially relevant in [[apologetics]], where the two major traditions tend to favor different structures.
