"The First Cause" is a philosophical treatise by the outstanding German thinker Arthur Schopenhauer, in which the author examines the main reasons for the existence and functioning of the world. He considers the concept of will as the basic impulse underlying everything that exists, and attempts to reveal the essence of this concept through the analysis of metaphysical and psychological aspects. Schopenhauer expresses his thoughts about human nature, the meaning of life, morality, truth, happiness and much more. A new view of the world will be opened to the reader and the justification of many eternal questions that have worried mankind since ancient times will be offered. "The First Cause" is an excellent work for those who are interested in philosophy and want to learn more about the depth of the world around us.
