Faced with the opportunity of espionage, a Communist, though he may sometimes hesitate momentarily, will always, exactly to the degree that he is a Communist, engage in espionage. The act will not appear to him in terms of betrayal at all. It will, on the contrary, appear to him as a moral act, the more deserving the more it involves him in personal risk, committed in the name of a faith (Communism) on which, he believes, hinges the hope and future of mankind, and against a system (capitalism) which he believes to be historically bankrupt. At that point, conscience to the Communist, and conscience to the non-Communist, mean two things as opposed as the two sides of a battlefield. The failure to understand that fact is part of the total failure of the West to grasp the nature of its enemy, what he wants, what he means to do and how he will go about doing it. It is part of the failure of the West to understand that it is at grips with an enemy having no moral viewpoint in common with itself, that two irreconcilable viewpoints and standards of judgment, two irreconcilable moralities, proceeding from two irreconcilable readings of man’s fate and future are involved, and, hence, their conflict is irrepressible. (Whittaker Chambers, Witness, 420)
