The name Georg Wilhelm Friedrich Hegel for many has long been synonymous with the word "philosopher". The Russian thinker Vladimir Solovyov, speaking of Hegel, remarked: "of all philosophers, philosophy was everything to him alone." "Phenomenology of spirit" — the first of the major works of the philosopher and at the same time it is the pinnacle of classical philosophy. Published in 1807, in the two centuries since, the Phenomenology of the spirit has been the subject of much research and interpretation, it has been hotly debated, and there is no thinker who has not been influenced by a coherent philosophical system. Consciousness, self-consciousness, absolute subject, sense certainty, perception, reason, spirit, morality, religion, absolute knowledge, are all concepts of the phenomenology of spirit, or the science of the experience of consciousness.
