From the beginning of 1914 until his death in 1944, Mondrian wrote more than a hundred essays on the subject of art and society. He wrote in Dutch, French and English, his choice of language often depending on his place of residence. All of Mondrians writings proclaim his conviction that art paves the way to a better society. Many of his texts have been published, but the original versions were often translated, edited, and polished. This book aims to present the painters words as he wrote them, going back to the original sources of all of Mondrians manuscripts, typescripts, and personal papers.
