The main Divisions will be--1. From Thales and Pythagoras to the appearance of the Sophists. 2. And of Socrates. The character and effect of Socrates' life and doctrines, illustrated in the instances of Xenophon, as his most faithful representative, and of Antisthenes, or the Cynic sect, as the one partial view of his philosophy, and of Aristippus, or the Cyrenaic sect, as the other and opposite extreme. 3. Plato and Platonism. 4. Aristotle and the Peripatetic school. 5. Zeno and Stoicism, Epicurus and Epicureans, with the effects of these in the Roman republic and empire. 6. The rise of the Eclectic or Alexandrine Philosophy, the attempt to set up a pseudo-Platonic Polytheism against Christianity, the degradation of Philosophy itself into mysticism and magic, and its final disappearance, as Philosophy, under Justinian. 7. The resumption of the Aristotelian philosophy in the thirteenth century, and the successive re-appearance of the different sects from the restoration of literature to our own times.[99] The last letter refers to lectures delivered from 19th December 1818 to April 1819, his tenth course. Another course on Shakespeare was also being given at the same time, at the Crown and Anchor tavern, Strand (Dykes Campbell's _Life_, 238), commencing 17th December 1818. No record has been published of these two series of lectures (see _Lamb's Letters_, ii, 16). The next letter is about Wordsworth and the _Edinburgh Review_, and repeats some of Coleridge's strong convictions against anonymous criticism. LETTER 173. TO ALLSOP Dec. 2nd, 1818. My Dear Sir,
