Of all fetishes which have misled humanity, perhaps none is responsible for more error than that of originality. As if anything could be new that was true, or true that was new! The only possible lines along which novelty or progress can lie are our reports, combinations, and expressions. Some people think they have done for a poet if they have shown that he made use of suitable materials in the construction of his poem! So Shakespeare has been shown to have used whole scenes from earlier writers. So Virgil, by Macrobius, has been shown to have laid under contribution every writer then known to be worth ransacking. Dante has also been shown to have re-edited contemporary apocalypses. So Homer, even, has been shown to re-tell stories gathered from many sources. The result is that people generally consider Shakespeare, Virgil, or Homer great in spite of their borrowings, when, on the contrary, the statement should be that they were great because of their rootage in the best of their period. In other words, they are great not because of their own personality (which in many cases has dropped out of the ken of history), but because they more faithfully, completely, and harmoniously represent their periods than other now forgotten writers. Therein alone lay their cosmic value, and their assurance of immortality. They are the voices of their ages, and we are interested in the significance of their age, not in them personally. It is from this standpoint that we must approach Plato. Of his personality what details are known are of no soteriologic significance; and the reason why the world has not been able to get away from him, and probably never will, is that he sums up prior Greek philosophy in as coherent a form as is possible without doing too great Procrustean violence to the elements in question. This means that Plato did not fuse them all into one absolutely, rigid, coherent, consistent system, in which case his utility would have been very much curtailed. The very form of his writings, the dialogue, left each element in the natural living condition to survive on its merits, not as an authoritative oracle, or Platonic pronunciamento, or creed.
