ABSTRACT Mixed martial arts (MMA) fighting in a competition is not necessarily wrong and is often, as far as we can tell, permissible. Our argument has two premises. First, if an act does not infringe on anyone’s moral right or violate another side-constraint, then it is morally permissible. Second, MMA-violence does not infringe on anyone’s moral right or violate another side-constraint. The first premise rests on two assumptions. First, if a person does a wrong act, then he wrongs someone. Second, if one person wrongs a second, then the first infringes on the second’s right. We then look at Nicholas Dixon’s powerful Kantian argument that MMA fighting is wrong.

混合武术的权利和同意

摘要一场比赛中的混合武术（MMA）不一定是错误的，而且据我们所知，通常是允许的。我们的论点有两个前提。首先，如果一项行为没有侵犯任何人的精神权利或侵犯另一种附带条件，那么在道德上是允许的。其次，MMA暴力不会侵犯任何人的精神权利或侵犯其他附带条件。第一个前提基于两个假设。首先，如果一个人做错了事，那么他就错了一个人。其次，如果一个人第二秒钟犯错，那么第一个侵犯第二个法官的权利。然后，我们看看尼古拉斯·迪克森（Nicholas Dixon）有力的康德论说，MMA战斗是错误的。
