Various viewpoints have been expressed in favor and against physicalism; But the requirement for accurate assessment of physicalism is to have a correct understanding of physicalism. In this article, apart from criticizing physicalism, we want to reach a correct understanding of physicalism. In the meantime, understanding what the physical is has a key role in defining physicalism. There are two well-known views of physics: “object-based” and “theory-based”. In the first view, the physical is defined on the model of exemplary physical objects; that is, it is a physical thing that has the property of physical prominent objects. In the second view, it is a physical that the physics discusses it. In the present article, we will show that both views have problems and we must replace the two mentioned views with a third view in understanding the physical. According to our belief, the correct perception is the “property-based” view. Among the “property-based” views, the most recent theories about the material-immaterial distinction belong to Ostad Fayazi, who introduces the property of standard of physical as perceptibility. While criticizing his point of view, we have finally introduced the "talent of realization in the world of physic" as a distinct and original difference between the physical and the non-physical, and in the meantime we have reached other results.
