“Therefore it is not arrogance or narrow-mindedness that leads the economist to discuss these things from the standpoint of economics. No one, who is not able to form an independent opinion about the admittedly difficult and highly technical problem of calculation in the socialist economy, should take sides in the question of socialism versus capitalism. No one should speak about interventionism who has not examined the economic consequences of interventionism. An end should be put to the common practice of discussing these problems from the standpoint of the prevailing errors, fallacies, and prejudices. It might be more entertaining to avoid the real issues and merely to use popular catchwords and emotional slogans. But politics is a serious matter. Those who do not want to think its problems through to the end should keep away from it.”
