A collectivist conception of man does not concede a valid existence to such sentiments as love, tenderness, and friendship; the abstract identity of individuals merely authorizes a comradeship between them by means of which each one is likened to each of the others. In marching, in choral singing, in common work and struggle, all the others appear as the same; nobody ever dies. On the contrary, if individuals recognize themselves in their differences, individual relations are established among them, and each one becomes irreplaceable for a few others.
