Georg Wilhelm Friedrich Hegel

In the process of analyzing the nature of Absolute Spirit, Hegel made significant contributions in a variety of philosophical fields, including the philosophy of history and social ethics. With respect to history, his two key explanatory categories are reason and freedom. “The only Thought,” maintained Hegel, “which Philosophy brings ... to the contemplation of History, is the simple conception of Reason; that Reason is the Sovereign of the world, that the history of the world, therefore, presents us with a rational process.” As a rational process, history is a record of the development of human freedom, for human history is a progression from less freedom to greater freedom.

Hegel's social and political views emerge most clearly in his discussion of morality (Moralität) and social ethics (Sittlichkeit). At the level of morality, right and wrong is a matter of individual conscience. One must, however, move beyond this to the level of social ethics, for duty, according to Hegel, is not essentially the product of individual judgment. Individuals are complete only in the midst of social relationships; thus, the only context in which duty can truly exist is a social one. Hegel considered membership in the state one of the individual's highest duties. Ideally, the state is the manifestation of the general will, which is the highest expression of the ethical spirit. Obedience to this general will is the act of a free and rational individual. Hegel emerges as a conservative, but he should not be interpreted as sanctioning totalitarianism, for he also argued that the abridgment of freedom by any actual state is morally unacceptable.

At the time of Hegel's death, he was the most prominent philosopher in Germany. His views were widely taught, and his students were highly regarded. His followers soon divided into right-wing and left-wing Hegelians. Theologically and politically the right-wing Hegelians offered a conservative interpretation of his work. They emphasized the compatibility between Hegel's philosophy and Christianity. Politically, they were orthodox. The left-wing Hegelians eventually moved to an atheistic position. In politics, many of them became revolutionaries. This historically important left-wing group included Ludwig Feuerbach, Bruno Bauer, Friedrich Engels, and Karl Marx. Engels and Marx were particularly influenced by Hegel's idea that history moves dialectically, but they replaced Hegel's philosophical idealism with materialism.

Hegel's metaphysical idealism had a strong impact on 19th-century and early 20th-century British philosophy, notably that of Francis Herbert Bradley, and on such American philosophers as Josiah Royce, and on Italian philosophy through Benedetto Croce. Hegel also influenced existentialism through the Danish philosopher Søren Kierkegaard. Phenomenology has been influenced by Hegel's ideas on consciousness. The extensive and diverse impact of Hegel's ideas on subsequent philosophy is evidence of the remarkable range and the extraordinary depth of his thought.
