§ 183. In absolute idealism, the principle of subjectivism is extended to reason itself. This extension seems to have been originally due to moral and religious interests. From the moral stand-point the contemplation of the truth is a _state_, and the highest state of the individual life. The religious interest unifies the individual life and directs attention to its spiritual development. Among the Greeks of the middle period life was as yet viewed objectively as the fulfilment of capacities, and knowledge was regarded as perfection of function, the exercise of the highest of human prerogatives. But as moral and religious interests became more absorbing, the individual lived more and more in his own self-consciousness. Even before the Christian era the Greek philosophers themselves were preoccupied with the task of winning a state of inner serenity. Thus the Stoics and Epicureans came to look upon knowledge as a means to the attainment of an inner freedom from distress and bondage to the world. In other words, the very reason was regarded as an activity of the self, and its fruits were valued for their enhancement of the welfare of the self. And if this be true of the Stoics and the Epicureans, it is still more clearly true of the neo-Platonists of the Christian era, who mediate between the ancient and mediæval worlds. [Sidenote: Emphasis on Self-consciousness in Early Christian Philosophy.] § 184. It is well known that the early period of Christianity was a period of the most vivid self-consciousness. The individual believed that his natural and social environment was alien to his deeper spiritual interests. He therefore withdrew into himself. He believed himself to have but one duty, the salvation of his soul; and that duty required him to search his innermost springs of action in order to uproot any that might compromise him with the world and turn him from God. The drama of life was enacted within the circle of his own self-consciousness. Citizenship, bodily health, all forms of appreciation and knowledge, were identified in the parts they played here. In short the Christian consciousness, although renunciation was its deepest motive, was reflexive and centripetal to a degree hitherto unknown among the European peoples. And when with St. Augustine theoretical interests once more vigorously asserted themselves, this new emphasis was in the very foreground. St. Augustine wished to begin his system of thought with a first indubitable certainty, and selected neither being nor ideas, but _self_. St. Augustine's genius was primarily religious, and the "Confessions," in which he records the story of his hard winning of peace and right relations with God, is his most intimate book. How faithfully does he represent himself, and the blend of paganism and Christianity which was distinctive of his age, when in his systematic writings he draws upon religion for his knowledge of truth! In all my living, he argues, whether I sin or turn to God,
