The work of Attila Csörgő draws our attention to the ancient philosophical issue between Realists and Nominalists. As is well known, the Realists, dating back to Plato, insisted on the existence of some common essences, primary to the manifestation of existence. The Nominalists, following the Sophists, claimed that there is nothing com- mon: existence in its concrete forms and manifestations are what is important, not essences. In his work Csörgő constantly refers to basic plastic forms – sphere, cube, pyramid, etc. However, these obvious manifestations of the common are deprived of an absolute self-sufficiency. It appears that they can be derivatives of each other. For example, the artist tells us that "1 tetrahedron + 1 tetrahedron = 1 cube". Moreover, it appears that not only concrete things ascend to absolute forms, but also vice versa. For example, a tridimensional sphere can be created by swerving a spiral plane, likewise a recomposed strip of an orange skin can reconstruct the tridimensional volume of an orange. Therefore, essences help us to systematize the variety of the world and an experience of existence among concrete things helps us to comprehend common ideas. If we accept that common and private, essence and existence, are basic categories of being, Attila Csörgő's art appears to be a staged dialectic of these ideas, their mutual dependencies and relations.
