"To Eternal Peace: A Philosophical Essay" is the work of the outstanding German philosopher Immanuel Kant, which became an important contribution to the development of political philosophy. In this book, the author considers the possibility of achieving eternal peace by establishing equality between states, consolidating international law and forming cosmopolitan ideals. Kant analyzes the nature of war, justifies the need to recognize human rights and calls for the construction of a world order based on morality and mutual respect. This work keeps its ideas relevant even today, reminding about the importance of observing international laws and obligations to preserve world peace."
