"One of the most compelling of twentieth-century ethical and literary heroes."
–Susan Sontag
"I can't think of anyone else who has written about the revolutionary movement in this century with Serge's combination of moral insight and intellectual richness."
–Dwight Macdonald
"To me he has seemed a model of the independent intellectual in Europe between the wars: leftist but not dogmatic, political yet deeply involved with issues of cultural life, and a novelist of very considerable powers."
–Irving Howe
"I believe indeed that to rescue the humanist tradition of the last decades is of the utmost importance, and that Victor Serge is one of the outstanding personalities representing the socialist aspect of humanism."
–Erich Fromm
"Victor Serge died in exile and obscurity, apparently no more than a splinter of a splinter in the Marxist movement. But with the passage of the years, he looms up as one of the great moral figures of our time, an artist of such integrity and a revolutionary of such purity as to overshadow those who achieved fame and power. His failure was his success. I know of no participant in Russia's revolution and Spain's agonies who more deserves the attention of our concerned youth."
–I.F. Stone
"I know of no other writer with whom Serge can be very usefully compared. The essence of the man and his books is to be found in his attitude toward the truth.... His life and its choices demonstrate an exemplary truth to which he was prophetically sensitive and which we should now accept as axiomatic. Institutions can be defended by lies, revolutions never."
–John Berger, New Society
