The centenary of regaining independence by Poland arouses complex reflections. It leads to summaries but also arouses interest in the processes accompanying these events. The manuscript of Bogdan Suchodolski’s handwriting is an interesting document from this period. There is a reflection about the moral consequences of the First World War and questions about the future of the post-war world. A clear inspiration of Schopenhauer’s pessimism can be noticed there, which makes it an exceptional document in his work and at the same time casts an interesting light on his other achievements.
