Many literary works would never have existed if there had not been tragedy in the lives of their authors. In moments of extreme unhappiness in the life of a man or nation, art often blossoms and gives inspiration for the fight against fate. The arts, especially poetry, then sometimes reach heights unattainable under normal conditions.
In Poland, in periods of war and occupation, literature has always helped to keep alive the patriotism and fighting-spirit of the people. When war has forced a great number of Poles to live in exile, Polish literature, too, has divided into two currents. Writers in exile have created inspired and profound works, especially in poetry. Works written by those who stayed at home were, in general, of less artistic value and more realistic: they were pictures of hard and bitter life.
