The article analyzes Karl Jaspers' concept of truth and freedom, which stems from the Gospel of John: "You will know the truth, and the truth will set you free." Jaspers sees freedom as recognized necessity and its root in truth. Freedom without truth is empty, it only makes sense when it has content and strives towards "common truth," which anchors us in language, rules, and respect for others, even when we are adversaries. Without freedom and respect for it, there is no peace. Truth is not something finished, but a constant search, a journey. Jaspers radically reverses the traditional concept of truth: the primary element is not the content (adequatio rei et intellectus), but the way of thinking, how the content is communicated. Truth, therefore, withdraws when we behave inappropriately, our soul is blind, and our spirit is deaf, when we stop communicating. The way of thinking is more important than the content, no matter how "good" or "bad" it may be. The author criticizes the naive belief in the "free world" and emphasizes that freedom is a chance that must be seized with seriousness, not a state we automatically possess. Reflections on Jaspers' biography and his relationship with Kierkegaard supplement the text, which also critically evaluates certain aspects of Jaspers' thought, such as his conception of history and his relationship to morality, placing him in a broader philosophical and theological context.
