Abstract
This book's fourteen short essays are neither very technical nor definitive, as Schaff warns in his forward. They do, however, reveal the struggle of a sincere philosopher, who happens also to be a high official of the Polish Communist Party, against the absolutes that plague him—absolute determinism, total party discipline, the definitive revolution. Schaff here continues his debate with the existentialists, notably Sartre, and contributes some clarification to the problem of "Marxist ethics."—W. L. M.
