How did Piet Mondrian’s spiritual beliefs shape his search for harmony in painting?

Piet Mondrian’s search for harmony was deeply rooted in his spiritual beliefs, particularly his commitment to theosophy, which posits a cosmos where spirit and matter are unified. Joining the Theosophical Society in 1909, Mondrian sought to move beyond the representation of individual objects to convey a universal, spiritual truth through his art.1

His vision was further shaped by the philosopher M.H.J. Schoenmaekers, who provided graphic rules regarding the symbolic meaning of lines and the mathematical construction of the universe. These ideas guided Mondrian toward neoplasticism, a style that rejected naturalistic subjects in favor of a "true vision of reality" expressed through primary colors and a grid of vertical and horizontal lines.23

By stripping away the "casual, arbitrary facts of everyday appearance," Mondrian aimed to create a Utopia of clarity and force. His work was not merely aesthetic; it held ethical significance, as he believed art could serve as a guide to humanity, helping viewers achieve a state of heightened consciousness and a more harmonious view of life.42
