Abstract: In The Stone Face, William Gardner Smith explores the Lucifer effects in American and French societies from the problems of dehumanization, hostility in imagination and groupthink and reveals the dilemma of human existence and ethical cognition under the pressure of systematic and situational forces, denouncing the brutalities of racists and sexists. As an American Black and a settler in Paris, he probes into the locality and unreasonableness of racial prejudice and discrimination and then gains a profound consideration of American race problems, disclosing racists' anti-human nature in his delineation of race situations in Europe. Racists lose their humanity and become the destroyers of human civilization when they divest the victims of their human rights.

Key words: William Gardner Smith, The Stone Face, Lucifer effects, evil
