Everyone carries a part of society on his shoulders; no one is relieved of his share of responsibility by others. And no one can find a safe way out for himself if society is sweeping toward destruction. Therefore, everyone, in his own interests, must thrust himself vigorously into the intellectual battle. None can stand aside with unconcern; the interest of everyone hangs on the result. Whether he chooses or not, every man is drawn into the great historical struggle, the decisive battle into which our epoch has plunged us.
