At times it must be admitted that Plato sounds very unreal. His faults are clear enough. The dialogue form makes it very easy for him to invent questions of such a nature that the answer he wants is the only one possible. Again, his conclusions are often arrived at by methods or arguments which are frankly inadmissible; in the earlier dialogues are some very glaring instances of sheer logical worthlessness. Frequently the whole theme of discussion is such that no modern philosopher could be expected to approve of it. A supposed explanation of a difficulty is sometimes afforded by a myth, splendid and poetical but not logically valid. Inconsistencies can easily be pointed out in the vast compass of his speculations. It remained for Aristotle to invent a genuine method of sorting out a licit from an illicit type of argument. These faults are serious. Against them must be placed some positive excellences. Plato was one of the first to point out that there is a problem; a question should be asked and an answer found if possible, for we have no right to take things for granted. More than this, he was everywhere searching for knowledge, ridding himself of prejudice, doing in perfect honesty the most difficult of all things, the duty of thinking clearly. These thoughts he has expressed in the greatest of all types of Greek prose, a blend of poetic beauty with the precision of prose. But Plato's praise is not that he is a philosopher so much as Philosophy itself in poetic form. His great visions of the Eternal whence we spring, his awe for the real King, the real Virtue, the real State "laid up in Heaven" fill him with an inspired exaltation which lifts his readers to the Heaven whence Platonism has descended. There are two main types of men. One is content with the things of sense; using his powers of observation and performing experiments he will become a Scientist; using his powers of speculation he will become an Aristotelian philosopher; putting his thoughts into simple and logical order, he will write good prose. The other soars to the eternal principles behind this world, the deathless forms or the general concepts which give concrete things their existence. These perfect forms are the main study of the Artist, Poet, Sculptor, whose work it is to give us comfort and pleasure unspeakable. So long as man lives, he must have the perfection of beauty to gladden him, especially if Science is going to test everything by the ruler or balance or crucible. This love of Beauty is exactly Platonism. It has never died yet. From Athens it spread to Alexandria, there to start up into fresh life in the School of which Plotinus is the chief; its doctrines are described for the English reader in Kingsley's _Hypatia_. It planted its seed of mysticism in Christianity, with which it has most strange affinities. At the Renaissance this mystic element caught the imagination of northern Europe, notably Germany.
