The book "Sören Kierkegaard: An Introduction" by Konrad Paul Liessmann offers a well-founded and accessible introduction to the thinking of the Danish philosopher Sören Kierkegaard. Instead of systematizing Kierkegaard's complex ideas, the author closely adheres to the original texts, conveying the dynamics and paradoxes that characterize Kierkegaard's work. Liessmann avoids abstract explanations, allowing readers to experience the tension and challenges of Kierkegaard's philosophy for themselves. Through the exploration of the pseudonyms and the crisis of the self, the relevance of Kierkegaard's thoughts for today's time becomes clear. This introduction is thus not only a theoretical engagement but also an inspiring approach to one of the most significant thinkers in the history of philosophy.
