“Unfortunately, violence is often offered as a solution to violence.”

Translation of his defense testimony at his 1999 trial http://web.archive.org/20020203190623/www.geocities.com/kurdifi/ocelan.html.
Context: Every ideology and mode of belief can, if true, implement itself by using the resources of technology and above all those of the media without having to resort to violence. In other words, violence has become unnecessary. In fact things have got to the point where violence cannot be afforded. The rich variety of institutions and practices the democratic system offers is built on this social and scientific-technological development, and whatever problem it tackles, it offers a certain solution. It itself is the solution.
To go through the examples, the solution to religious wars is secularism. Here the standard and the implementation involve taking the approach that everyone is free to follow their religious beliefs and democratic criteria will apply to all of them. Democracy offers definite freedom of belief and this is the antidote to religious wars.
Again the same applies to the fields of thought and ideology. There is freedom of thought and conviction. It is allowed to work as one wants and implement one's beliefs as long as one does not infringe the rights of others in this respect. This also applies to political ideas and their expression in the form of parties. As long as it adheres to the democratic system and its state structure, every party can offer a solution without resorting to violence. There is no question here of either imposing a religion by force or breaking and shattering the structure of the state. Religion, thought and the parties based on them know to meet the standards of the democratic system of the state because they are based on them. If they don't know how to do this, then democracy gets the right to defend itself.
It is clear here that regardless of the social group they are based on (which might be a nation or an ethnic or religious group), beliefs, ideas and the parties through which they are expressed cannot, in the name of these beliefs and ideas, force the limits on which the state is based. There is no need for this, because it will render the problem they claim to be solving even worse. Consequently, there is no need for it, and, in any case, there are solutions within the system. These are the democratic rights of those groups. They are their freedoms of belief and thought. They are the parties. They are all types of coalitions. In the area of language and culture, the democratic solution is even more striking. This is the area where the greatest successes have been achieved. Because the intermingling of language and culture, these values that many national groups have assimilated together for centuries, do not want to separate and get weak and monotonous, but prefer to stay together to get enriched and achieve variety, strength and life. And the school and laboratory for this is democracy and its implementation with conviction.
Democracy is almost a garden of language and culture. The most developed and powerful principles of our day once again express this clearly. All European countries and North America are clear proofs of it. The attempt to suppress new religious, linguistic, cultural, intellectual and political developments during past centuries was the cause of all major wars, and resistance against suppression gave to wars which could be seen as understandable. Particularly in European countries this experience led to the development of a determined democracy in the wake of all these wars and led to the supremacy of the West. Western civilisation can, in this sense, be termed democratic civilisation. The democratic system is at least as important as scientific and technological superiority. Feeding off each other, they both became strong and achieved the status of world civilisation.

1950s, Three Ways of Meeting Oppression (1958)
Context: A second way that oppressed people sometimes deal with oppression is to resort to physical violence and corroding hatred. Violence often brings about momentary results. Nations have frequently won their independence in battle. But in spite of temporary victories, violence never brings permanent peace. It solves no social problem; it merely creates new and more complicated ones.

: The Foundations of Liberal Policy § 10. The Argument of Fascism https://mises.org/liberal/ch1sec10.asp,Ch.1
Liberalism (1927)
Context: 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.

1960s
Context: I met Malcolm X once in Washington, but circumstances didn't enable me to talk with him for more than a minute. He is very articulate … but I totally disagree with many of his political and philosophical views — at least insofar as I understand where he now stands. I don't want to seem to sound self-righteous, or absolutist, or that I think I have the only truth, the only way. Maybe he does have some of the answer. I don't know how he feels now, but I know that I have often wished that he would talk less of violence, because violence is not going to solve our problem. And in his litany of articulating the despair of the Negro without offering any positive, creative alternative, I feel that Malcolm has done himself and our people a great disservice. Fiery, demagogic oratory in the black ghettos, urging Negroes to arm themselves and prepare to engage in violence, as he has done, can reap nothing but grief.
