The book examines the role of sculpture in the 20th century and in previous centuries of art history. The question is raised about the nature of plastic. What is this (arbitrarily free) variation on the theme of the human body, or is it simply any object in space? Depending on the answer, one can imagine the current state of this art form either as critical, suggesting doubts about the viability of plastic, or experiencing an unprecedented flowering, because from the point of view of three-dimensional objects, almost everything today has become a sculpture. Leaning towards the first option, the author expresses hope for the continuation of truly plastic, that is, artistic practices related to the representation of the body - quite not necessarily in the (narrow) sense that the concept of "physicality" is now given.
