To tell a Greek idolater that the divine Plato thought it a great MYSTERY that one and one should make two, that he declared it to be incomprehensible to him, and thought the only possible solution of the mystery to be, that two is produced "by _participation in duality_," would surprise him; but he would be still more surprised to learn that this is only a specimen brick of Plato's divine philosophy, as it abounds in similar puerilities. I have long since reviewed this effete philosophy of an ignorant age, and shown its true character, but my work has never been offered to a bookseller. Yet it shall not be suppressed. The destruction of stultifying superstitions is as necessary in education and literature as in religion. The ponderous blows of Lord Bacon upon this Greek superstition of the literary classes did not prove fatal, for the same reason that animal organisms of a low, cold-blooded, grade are hard to kill,--they must be cut up in fragments before their death becomes complete; superstitions and beliefs that have no element of intelligent reason, and are perpetuated by social influence, authority, and domination over the young become a blind force that resists all influence from reason. If my readers are interested in the destruction of venerable and powerful falsehoods that stand in the way of every form of progress, I may be tempted to publish a cheap edition of my work on Greek Philosophy and Logic. It is not in the least presumptuous to lay hands upon this venerable illusion, and show that it has not even the vitality of a ghost. It is but a simulacrum or mirage, and it is but necessary to approach it fearlessly, and walk through it, to discover its essential nonentity. SYMPOSIUMS deserves a good report. One of the philosophers, whose doctrines were poetically paraphrased in the report of the scientific responses upon human immortality, writes that he enjoyed the poetical paraphrase very much, and never laughed over anything so heartily. It would be pleasant to hear the real sentiments of the remainder. It would be equally interesting to hear how Prof. Harris and the other Concordians enjoy the little sketch of their symposium. LITERATURE OF THE PAST.--"In an article on the 'Archetypal Literature for the Future,' by Dr. J. R. Buchanan, which appears in the JOURNAL OF MAN for March, the writer foreshadows a time to which the American mind is fast advancing when the literature of the past will take its place amongst the mouldering mass which interests the antiquarian, but has no positive influence in guiding the thoughts and actions of the passing generation. There are some indications of a movement in that direction in other countries, though the vast majority, including many Spiritualists and Theosophists, still explore the records of past ages, looking for the light which is shining all about them in the present, unrealized."--_Harbinger of Light_, Australia.
