Hölderlin’s heroism is splendid because it is free from pride and devoid of confidence in victory. All he is aware of is his mission, the summons from the invisible world; he believes in his calling, but has no assurance of success. He is forever vulnerable…It is the feeling that he is foredoomed to destruction, that a menacing shadow dogs his footsteps, which makes his persistence in his chosen course so courageous. The reader must not think that Hölderlin’s faith in poesy as the profoundest meaning of life implies a like belief in his own poetic gifts. As regards these latter he remained humble-minded…Yet for all this personal modesty, for all this sensitiveness, he had a will of steel to animate his devotion to poesy, to fortify him for self-immolation. “My dear friend,” he writes to one of his intimates, “when will people come to see that in our case the greatest force is the most modest in its manifestations, and that the divine message (when it issues from us) is always uttered with humility and sadness?” His heroism was not that of the warrior, not the heroism of triumphant force; it was the heroism of the martyr who is ready, nay, glad, to suffer for the unseen, to perish on behalf of an ideal.
