"The Science of Logic" by Hegel is one of those works that leave a deep mark in the consciousness of a person, in his spiritual improvement. Thanks to his teachings, the famous German philosopher went down in history as an outstanding reformer of the science of thinking, of patterns and ways of knowing. The main task of logic, according to Hegel, is the knowledge of truth. And he explored the paths leading to truth and the evolution of those paths. Logic itself cannot be a complete science at any stage of its historical development - it leaves its doors open to new conclusions and concepts. Therefore, Hegel's teaching is always relevant and causes constant interest. All texts are provided with comments and explanations.
