Sol LeWitt published “Paragraphs on Conceptual Art” in Artforum, June 1967. They became an influential theoretical text on art of the twentieth century. They played the role of a manifesto even though they appeared when their topic - concept over matter - had already existed for about a decade. Digital computer art had had its first exhibitions in 1965. It seems it never produced a manifesto, with the exception, perhaps, of Max Bense’s “Projects of generative aesthetics” (1965, in German). Since computer art is a brother of conceptual art, it is justified in a late manifesto to borrow the style of the old title.
