The same procedures I would use to get someone to agree with me are the same ones I would use to prove that I have the truth that corresponds with reality. Hence, there is no point in polluting and complicating dialogue with irrelevant considerations. In most respects we are where we have always been. We live in a world filled with many moral perspectives. They differ in their fundamental assumptions, the foundations of belief, the norms of right and wrong, ways of testing and revising positions, and so on.
Arguments take place when controversy arises.
The contending parties lay out the reasons why they think they are right and why they believe the opposing parties are wrong. Usually no one is convinced by the arguments against them or for the views they reject. Sometimes people do change their minds either by confronting arguments they cannot answer, coming to see things in a different light, discovering they had been wrong in their facts or in their interpretation of a situation, and the like. Disputants may even convert others to their point of view by the power of their reasoning or interpretation. Frequently change occurs when they discover in experience that their theory has destructive consequences for people in real life.
