Talya Lerman gives a presentation on Sol LeWitt’s “Sentences on Conceptual Art” (1969), his summary of thoughts on art, beginning with 1. "Conceptual artists are mystics rather than rationalists. They leap to conclusions that logic cannot reach." LeWitt is regarded as a founder of both Minimal and Conceptual art. His prolific two and three-dimensional work ranges from wall drawings (over 1200 of which have been executed) to hundreds of works on paper extending to structures in the form of towers, pyramids, geometric forms, and progressions. These works range in size from gallery-sized installations to monumental outdoor pieces.

"Sol LeWitt: A Wall Drawing Retrospective", a collaboration between the Yale University Art Gallery, MASS MoCA (Massachusetts Museum of Contemporary Art), and the Williams College Museum of Art opened to the public in 2008 at MASS MoCA in North Adams, Massachusetts. The exhibition will be on view for 25 years and is housed in a three-story 27,000-square-foot historic mill building in the heart of MASS MoCA’s campus, fully restored and outfitted with a sequence of new interior walls constructed to LeWitt’s specifications. The exhibition consists of 105 drawings — comprising nearly one acre of wall surface — that LeWitt created over 40 years from 1968 to 2007 and includes several drawings LeWitt created for the project shortly before his death.
