Mr. LeWitt helped establish Conceptualism and Minimalism as dominant movements of the postwar era. His work—sculptures of white cubes, or drawings of geometric patterns, or splashes of paint like Rorschach patterns—tested a viewer’s psychological and visual flexibility. See a line. See that it can be straight, thin, broken, curved, soft, angled or thick. Enjoy the differences. The test was not hard to pass if your eyes and mind were open, which was the message of Mr. LeWitt’s art. He reduced art to a few of the most basic shapes (quadrilaterals, spheres, triangles), colors (red, yellow, blue, black) and types of lines, and organized them by guidelines he felt in the end free to bend. Much of what he devised came down to specific ideas or instructions: a thought you were meant to contemplate, or plans for drawings or actions that could be carried out by you, or not. Sometimes these plans derived from a logical system, like a game; sometimes they defied logic so that the results could not be foreseen, with instructions intentionally vague to allow for interpretation. Characteristically, he would then credit assistants or others with the results. With his wall drawing, mural-sized works that sometimes took teams of people weeks to execute, he might decide whether a line for which he had given the instruction “not straight” was sufficiently irregular without becoming wavy (and like many more traditional artists, he became more concerned in later years that his works look just the way he wished). But he always gave his team wiggle room, believing that the input of others—their joy, boredom, frustration or whatever— remained part of the art. In so doing, Mr. LeWitt gently reminded everybody that architects are called artists— good architects, anyway—even though they don’t lay their own bricks, just as composers write music that other people play but are still musical artists. Mr. LeWitt, by his methods, permitted other people to participate in the creative process, to become artists themselves. —Michael Kimmelman for the New York Times
