KANDINSKY, Wassily, 1926. Punkt und Linie zu Fläche: Beitrag zur Analyse der malerischen Elemente. Albert Langen.
The geometrical point is an invisible being. It must be defined therefore as an immaterial being. Materially thought the point resembles a Zero. But in this zero are hidden different qualities which are "human". In our conception this zero – the geometrical point – is connected with the highest scarcity, i.e. with the greatest restraint, which speaks however. Thus, the geometrical point is in our imagination the highest and most single connection of Silence and speaking. [⇒ Reden und Schweigen]
