There has been a great deal written of late years on the subject of the state of Greece and Rome during the pre-historic period; let us say before the Olympiads in Greece, and the war with Pyrrhus in the annals of Rome. Now, in a question like this, it is plain that the inquirer has first of all to decide on the point from which he is to start in the presence of the received accounts; on what side, from what quarter he is to approach them; on what principles his discussion is to be conducted; what he is to assume, what opinions or objections he is summarily to put aside as nugatory, what arguments, and when, he is to consider as apposite, what false issues are to be avoided, when the state of his arguments is ripe for a conclusion. Is he to commence with absolutely discarding all that has hitherto been received; or to retain it in outline; or to make selections from it; or to consider and interpret it as mythical, or as allegorical; or to hold so much to be trustworthy, or at least of _primâ facie_ authority, as he cannot actually disprove; or never to destroy except in proportion as he can construct? Then, as to the kind of arguments suitable or admissible, how far are tradition, analogy, isolated monuments and records, ruins, vague reports, legends, the facts or sayings of later times, language, popular proverbs, to tell in the inquiry? what are marks of truth, what of falsehood, what is probable, what suspicious, what promises well for discriminating facts from fictions? Then, arguments have to be balanced against each other, and then lastly the decision is to be made, whether any conclusion at all can be drawn, or whether any before certain issues are tried and settled, or whether a probable conclusion or a certain. It is plain how incessant will be the call here or there for the exercise of a definitive judgment, how little that judgment will be helped on by logic, and how intimately it will be dependent upon the intellectual complexion of the writer.
