Weston On Arguments
Once we have arrived at a conclusion that is well supported by reasons, we use arguments to explain and defend it. A good argument doesn't merely repeat conclusions. Instead it offers reasons and evidence so that other people can make up their minds for themselves. If you become convinced that we should indeed change the way we raise and use animals, for example, you must use arguments to explain how you arrived at your conclusion. That is how you will convince others: by offering the reasons and evidence that convinced you. It is not a mistake to have strong views. The mistake is to have nothing else.
