Can art help us make sense of war? War itself is a senseless act, and therefore looking to art to decipher its meaning, might be pointless. At the same time, art can communicate the reality of war in ways that journalism can’t. Art can also provide us with the emotional vision that can help us imagine a post-war, post-crisis future. But for the moment, while the war is ongoing, what the art world can do best is mobilise its network and help directly Ukrainian artists in practical terms, as well as make the world aware of the rich Ukrainian art scene, writes Charles Green.
