In Sinclair Lewis's book "It Can't Happen Here," the character Albert Einstein represents the struggle of intellectuals who face exile due to their beliefs and passions. Initially, Einstein was forced to leave Germany because of his commitment to mathematics, world peace, and his love for the violin, which were seen as incompatible with the prevailing ideologies of the time.

Later, he finds himself in America, where the same values that once made him a target in Germany now lead to his exile again. This highlights the ongoing conflict between individual principles and societal pressures, illustrating a troubling trend of intolerance towards those who seek to promote peace and knowledge.
