This text explores the philosophical concept of struggle as one of the key boundary situations in the work of Karl Jaspers. The author emphasizes that alongside death, which represents the central boundary situation, struggle also plays a fundamental role in human life, particularly in the form of immediate life-threatening danger on the front line. Jaspers' theory posits that in everyday life, a human being functions merely as an intra-worldly entity, or simple Dasein. Only when faced with boundary situations, which include the horrors of war and conflict, does a profound internal transformation occur. In these extreme moments, the individual breaks free from mundane existence to become a true existence. Within this context, struggle is understood as an ontological stage where a person truly becomes themselves and achieves authentic humanity. The text highlights the paradox that it is precisely through suffering and the confrontation with non-being that an individual can transcend the limits of their mere existence and realize their full human potential according to Jaspers' existential philosophy.
