Within these limits of its original and proper use, and as expressing a fact of mind, the word has an indisputable value. But the fact of the personal character of a _dogma_ soon became lost to sight. Two tendencies which grew with a parallel growth dominated the world in place of the recognition of it. It came to be assumed that certain convictions of certain philosophers were not simply true in relation to the philosophers themselves, and to the state of knowledge in their time, but had a universal validity: subjective and temporary convictions were thus elevated to the rank of objective and eternal truths. It came also to be assumed that the processes of reason so closely followed the order of nature, that a system of ideas constructed in strict accordance with the laws of reasoning corresponded exactly with the realities of things. The unity of such a system reflected, it was thought, the unity of the world of objective fact. It followed that the truth or untruth of a given proposition was thought to be determined by its logical consistency or inconsistency with the sum of previous inferences. These tendencies were strongly accentuated by the decay of original thinking. Philosophy in later Greece was less thought than literature. It was the exegesis of received doctrines. Philosophers had become professors. The question of what was in itself true had become entangled with the question of what the Master had said. The moral duty of adherence to the traditions of a school was stronger than the moral duty of finding the truth at all hazards. The literary expression of a doctrine came to be more important than the doctrine itself. The differences of expression between one thinker and another were exaggerated. Words became fetishes. Outside the schools were those who were littérateurs rather than philosophers, and who fused different elements together into systems which had a greater unity of literary form than of logical coherence. But these very facts of the literary character of philosophy, and of the contradictions in the expositions of it, served to spread it over a wider area. They tended on the one hand to bring a literary acquaintance with philosophy into the sphere of general education, and on the other hand to produce a propaganda. Sect rivalled sect in trying to win scholars for its school. The result was that the ordinary life of later Greece was saturated with philosophical ideas, and that the discordant theories of rival schools were blended together in the average mind into a syncretistic dogmatism.
