个例同一论是一种弱同一论,它既承认心理现象与物理现象的同一,又承认心理状态的可多样实现性。其中,以戴维森的“异态一元论”为典型,他认为世界上只有一种实在,即物理实在,但可以用心理概念和物理概念去描述和解释。个例同一论虽然坚持了马克思主义的世界的物质统一性原则,但由于它忽视社会历史因素对心理现象的作用,忽视社会实践,因而不能对心身问题做出完全科学的解答。 A case of the same theory is a kind of weak theory, it not only acknowledges the same psychological phenomena and physical phenomena, but also recognizes the diverse realization of mental states. Among them, Davidson ’s “monologue” as the typical, he believes there is only one kind of reality in the world, that is, physical reality, but can be used to describe and explain the concept of psychology and physics. Although the same doctrine insists on the principle of material unity in the Marxist world, it can not give a complete and scientific answer to psychosomatic problems because it ignores the role of social and historical factors in psychological phenomena and ignores social practice.
