=The Last Century and a Half of the Ethical Period.= (150 B. C.–1 A. D.). =Eclecticism.=――About 150 B. C. the Ethical Period became eclectic. After 150 years of passionate controversy the Schools began to compromise their differences and fuse into one another. They no longer emphasized their differences, but began to point to their common ground of unity. This tendency to fusion applies only to the Lyceum, the Academy, and the Porch. The Epicurean School was never a party to this eclecticism and always remained relatively stationary. The fusion occurred only in the teaching of the Schools and not in their organization. Externally the Schools remained separate bodies for six hundred years longer. In the second century Hadrian and the Antonines endowed separate chairs for them in the University of Athens. They were not abolished as Schools until 529 A. D., by Justinian. Internally their independent growth lasted only during the two centuries down to the year 150 B. C. At this time their theoretic mission had been completed. Their internal history from 100 B. C. to 529 A. D. was one of compromise and adjustment. The year 150 B. C. is therefore important. At this time the records of the Schools stop, controversy abates, Stoicism and Epicureanism are introduced into Rome, and fusion of doctrines begins. The Stoic School was the first to incline to eclecticism. Its own doctrine was a kind of fusion of incoherent parts, and among the Schools it could most easily welcome new doctrines. About 150 B. C., under the lead of Panætius and Posidonius, it adopted many of the Platonic and Aristotelian teachings, tempered its own ethical rigorism, and extended its scientific interests. At the same time the Peripatetics of the Lyceum united the pantheism of the Stoics to their own theism. After the death of Carneades in 129 B. C. the Academy turned from Skepticism back to the Platonic tradition, but it was a meagre Platonism adulterated with many foreign elements. For example, Antiochus of Ascalon taught Cicero from the Academy at Athens in the winter of 79–78 B. C. that Platonism and Aristotelianism were only different aspects of the same doctrine.
