Arguments about different value concepts are a central component of ethical reflection. Arguments are formed to support specific value judgements. The approach to the discussion and negotiation of values is primarily a cognitive one. A strength of cognitive ethical argumentation is, for example, that freedom from contradiction can be presented well, or the deductive validity of a conclusion from the listed premises, etc. The major disadvantage is that it is not possible to make a cognitive argument. The great disadvantage is that it reduces people to rational beings and tends to exclude people who argue emotionally or to defame them as disturbing.
