PICK OF THE DAY

Feats of Klee

Paul Klee was both a prolific artist and a significant influence on 20th-century European philosophy. “Paul Klee: Philosophical Vision; From Nature to Art” is the first exhibit to look at the relationship between Klee’s artistic output and his philosophical legacy. The show examines Klee’s love of nature, his views on modern society, and the ways in which his ideas manifest in his use of form, line, and color. It features more than 65 watercolors, drawings, etchings, illustrations, and oil paintings. Pictured: detail of “Printed Sheet With Pictures.’’ Through Dec. 9. Mon-Fri 11 a.m.-4 p.m. Sat-Sun noon-5 p.m. (closed Sept. 3, Oct. 8, Nov. 21-22). Docent-led tours 2-2:45 p.m. Sun or by request. Free. McMullen Museum of Art, Boston College, Devlin Hall 101, 140 Comm. Ave., Chestnut Hill. 617-552-8100, www.bc.edu/artmuseum
