Born in Paris in 1879 to a Cuban diplomat and a French woman, Picabia moved to New York as a painter in 1913. Upon returning to Europe, he became a key inspiration for the literary and artistic avant-garde in Paris, Zurich, and Barcelona. As a brazen eccentric and tireless player, he expressed popular wisdom and created aphorisms such as: "Every conviction is a disease" and his most famous: "Our head is round so that thinking can change direction." The sarcastic and ironic tone of these aphorisms, full of provocative contradictions, portrays Picabia as a witty and insightful juggler of the moment. This volume gathers all of his aphorisms.
