A complex argument is characterized by its structure, which typically involves multiple premises and may include intermediate conclusions that serve to support a final conclusion. An intermediate conclusion is a proposition that follows logically from some of the premises, and it can act as a stepping stone in the reasoning process leading to the overall conclusion. Thus, complex arguments allow for a more nuanced exploration of the relationships between various statements, which can enhance the persuasive quality of the overall argument.
In contrast, a simple argument generally presents a straightforward connection between a premise and a conclusion without the layers of reasoning that characterize complex arguments. Direct evidence arguments focus on establishing a conclusion based on specific, clear evidence without the intermediary steps. Circumstantial arguments, on the other hand, usually rely on contextual factors rather than a structured logical progression. These distinctions clarify why a complex argument is the most suitable type to include intermediate conclusions, as it inherently supports a more intricate form of reasoning.
