Final answer:
An antithesis is a position that opposes the main argument, while a strawman argument is a tactic that misrepresents the opposing argument to more easily counter it. Engaging with opposing viewpoints fosters a stronger understanding and presentation of an argument.
Step-by-step explanation:
An antithesis is a position that goes against the main viewpoint of an argument. In rhetoric, it offers a contrasting idea to the original thesis to show a balanced view of the topic. For example, if the thesis is that technology simplifies life, the antithesis might argue that technology often complicates life. Another tactic in debates is the use of a strawman argument, which is when someone utilizes a weaker version of the position being argued against in order to make the position easier to defeat. This misrepresentation can be challenged by adopting the stance of the opposition and brainstorming ideas to argue against one's original position. Overall, engaging with the antithesis or opposition encourages a deeper understanding of the argument at hand and aids in producing a more compelling discussion or essay.
