Book excerpt: By combining and colliding the unexpected, the US artist John Baldessari (1931-2020), created conceptual works that raise questions regarding what art is, how art is made, and what art can look like. After concluding in the 1960s that a photographic image or a text were more adequate expressions of his artistic intentions than painting, John Baldessari's practice took a new direction. Since then, Baldessari has combined subjects from the imagery of popular culture with linguistic examinations, creating works that challenge artistic norms and boundaries. Besides the two essays the book also includes a wide selection of Baldessari's own writings from 1968-2011.
