“Lectures on the History of Philosophy” is a three-volume work by Georg Wilhelm Friedrich Hegel (1770 - 1831) - a German philosopher, one of the founders of German classical philosophy, a consistent theorist of the philosophy of romanticism. In his fundamental work, Hegel shows an inextricable connection the subject of science with its history. Philosophy is the most difficult: eternal disagreements about what it is lead to the uncertainty of basic concepts. Despite this, philosophical thought has successfully developed over the centuries. The question of the truth of the teachings became the most important factor in its progress. Georg Hegel developed a powerful philosophical system of panlogism, in which the driving force of self-improvement is pure or absolute reason. He acts as an ideal substance. To transform it into absolute spirit, according to Hegel, is the task of world development. The ideas of the great German philosopher were embodied in his works “The Doctrine of Being”, “The Doctrine of Essence”, “The Doctrine of Concept”.
