The problem of determinism in history in the context of Karl Popper's philosophy

In this thesis, I deal with the problem of determinism in history. I have described the core questions that will determine a person's position in the context of the issue of determinism in history, and based on this description, I clarify Karl Popper's philosophical position on this issue. Accordingly, I first analyze the concepts of the philosophy of history, causality, determinism, and teleology and reveal their differences and similarities. Subsequently, by addressing the nomologicalism in the positive sciences and in the social sciences, I analyze the differences in these two areas in terms of predicting the future. In the section, I analyze the single-line, cyclical, and progress-based understanding of history with examples. Later, I emphasize that the examination of human is different from purely physical elements, since the human is an intentional-purposeful being. In the last part of my thesis, I examine Karl Popper's view of historicism. After handling his methodological explanation, I deal with examples of Karl Popper's way of associating holistic understandings of history with totalitarian regimes. In the same part, I clarify Popper's position by categorizing the debates on determinism according to different answers to the questions of whether there is a historical telos, and whether people have free will.
