And yet if we really wish to learn something from an example, how vague and elusive do we find the comparison! If it is to give us strength, many of the differences must be neglected, the individuality of the past forced into a general formula and all the sharp angles broken off for the sake of correspondence. Ultimately, of course, what was once possible can only become possible a second time on the Pythagorean theory, that when the heavenly bodies are in the same position again, the events on earth are reproduced to the smallest detail; so when the stars have a certain relation, a Stoic and an Epicurean will form a conspiracy to murder Cæsar, and a different conjunction will show another Columbus discovering America. Only if the earth always began its drama again after the fifth act, and it were certain that the same interaction of motives, the same _deus ex machina_, the same catastrophe would occur at particular intervals, could the man of action venture to look for the whole archetypic truth in monumental history, to see each fact fully set out in its uniqueness: it would not probably be before the astronomers became astrologers again. Till then monumental history will never be able to have complete truth; it will always bring together things that are incompatible and generalise them into compatibility, will always weaken the differences of motive and occasion. Its object is to depict effects at the expense of the causes--"monumentally," that is, as examples for imitation: it turns aside, as far as it may, from reasons, and might be called with far less exaggeration a collection of "effects in themselves," than of events that will have an effect on all ages. The events of war or religion cherished in our popular celebrations are such "effects in themselves"; it is these that will not let ambition sleep, and lie like amulets on the bolder hearts--not the real historical nexus of cause and effect, which, rightly understood, would only prove that nothing quite similar could ever be cast again from the dice-boxes of fate and the future.
