Whenever, therefore, among mystic enunciations we can detect the existence of some couched and specific note of identification, we may most certainly conclude that it is placed there to serve a future purpose of discrimination among several admissible modes of solution; or in other words, that the enigma is designedly so framed as to tempt and to allow a diversity of hypothetical explanations. An enigmatical or symbolical enunciation, conformed to these essential rules, serves the threefold purpose of presenting a blind to the incurious, a trap to the dogmatical, and an exercise of modesty, of patience, and of sagacity to the wise. And this seems to be the result intended, and actually accomplished by the symbolical prophecies of Scripture. When the subject of enigma already stands within the range of our knowledge, and requires only to be singled out, the process of solution is simple. The several suppositions that seem to comport with the ambiguous description are to be brought together; and then the special mark must be applied to each in turn, until such a precise and convincing correspondence is discovered as at once strips the false solutions of all their pretensions: if the enigma be fairly constructed, this method of induction will never fail of success. Thus, with the page of history before us, those prophecies of Daniel, for example, which relate to the invasion of Greece by the Persians, to the subsequent overthrow of the Persian monarchy by the Macedonians, to the division of the conquests of Alexander, to the spread of the Roman arms, and to the subdivision of the Roman Empire, are interpreted without hazard of error, and with a completeness and a speciality of coincidence, that carries a conviction of the divine dictation of those prophecies to every honest mind.
