V. The World Conceptions of the Modern Age of Thought Evolution

Lessing strives for the transformation of the religious truths of revelation into truths of reason. This aim is distinctly discernible in the various turns and aspects that his thinking has to take. Lessing feels himself with his self-conscious ego in a period of the evolution of mankind that is destined to acquire through the power of self-consciousness, what it had previously received from without through revelation. What has preceded this phase of history becomes for Lessing a process of preparation for the moment in which man's self-consciousness becomes autonomous. Thus, for Lessing, history becomes an “Education of the Human Race.” This is also the title of his essay, written at the height of his life, in which he refuses to restrict the human soul to a single terrestrial life, but assumes repeated earth lives for it. The soul lives its lives separated by time intervals in the various periods of the evolution of mankind, absorbs from each period what such a time can yield and incarnates itself in a later period to continue its development. Thus, the soul carries the fruits of one age of humanity into the later ages and is “educated” by history. In Lessing's conception, the “ego” is, therefore, extended far beyond the individual life; it becomes rooted in a spiritually effective world that lies behind the world of the senses.
