Question:

Why is it important for an argument to be valid?

Best Answer - Chosen by Asker: Arguments are TOOLS. They are things you use for a particular purpose. The characteristics of the best tool is going to vary depending on the nature of your purpose.

If you want to persuade someone through logic or if you want to use existing truths to demonstrate unknown truths, then it is CRITICAL that your arguments are valid.

If, on the other hand, you want to persuade someone by other means (emotion and other forms of rhetoric), or perhaps if you're constructing arguments for entertainment, exercise, and the like, it's not anywhere near as important to have a valid argument. Sometimes, requiring validity can just downright get in the way of these objectives.

So it goes.
