Mises: It is ideas alone, and not arms, that, in the last analysis, turn the scales

"Now it cannot be denied that the only way one can offer effective resistance to violent assaults is by violence. Against the weapons of the Bolsheviks, weapons must be used in reprisal, and it would be a mistake to display weakness before murderers. No liberal has ever called this into question. What distinguishes liberal from Fascist political tactics is not a difference of opinion in regard to the necessity of using armed force to resist armed attackers, but a difference in the fundamental estimation of the role of violence in a struggle for power. The great danger threatening domestic policy from the side of Fascism lies in its complete faith in the decisive power of violence. In order to assure success, one must be imbued with the will to victory and always proceed violently. This is its highest principle. What happens, however, when one's opponent, similarly animated by the will to be victorious, acts just as violently? The result must be a battle, a civil war. The ultimate victor to emerge from such conflicts will be the faction strongest in number. In the long run, a minority -- even if it is composed of the most capable and energetic -- cannot succeed in resisting the majority. The decisive question, therefore, always remains: How does one obtain a majority for one's own party? This, however, is a purely intellectual matter. It is a victory that can be won only with the weapons of the intellect, never by force. The suppression of all opposition by sheer violence is a most unsuitable way to win adherents to one's cause. Resort to naked force -- that is, without justification in terms of intellectual arguments accepted by public opinion -- merely gains new friends for those whom one is thereby trying to combat. In a battle between force and an idea, the latter always prevails.
Fascism can triumph today because universal indignation at the infamies committed by the socialists and communists has obtained for it the sympathies of wide circles. But when the fresh impression of the crimes of the Bolsheviks has paled, the socialist program will once again exercise its power of attraction on the masses. For Fascism does nothing to combat it except to suppress socialist ideas and to persecute the people who spread them. If it wanted really to combat socialism, it would have to oppose it with ideas. There is, however, only one idea that can be effectively opposed to socialism, viz., that of liberalism.
It has often been said that nothing furthers a cause more than creating, martyrs for it. This is only approximately correct. What strengthens the cause of the persecuted faction is not the martyrdom of its adherents, but the fact that they are being attacked by force, and not by intellectual weapons. Repression by brute force is always a confession of the inability to make use of the better weapons of the intellect -- better because they alone give promise of final success. This is the fundamental error from which Fascism suffers and which will ultimately cause its downfall. The victory of Fascism in a number of countries is only an episode in the long series of struggles over the problem of property. The next episode will be the victory of Communism. The ultimate outcome of the struggle, however, will not be decided by arms, but by ideas. It is ideas that group men into fighting factions, that press the weapons into their hands, and that determine against whom and for whom the weapons shall be used. It is they alone, and not arms, that, in the last analysis, turn the scales."
