But what--if we may propound the question with something more of philosophical indifference than the poet--what, according to the analogy of the divine economy and merciful justice, as elsewhere displayed, are we to suppose the doom of these undecided and wavering spirits? In the first place, we may well suppose that they would be submitted to a new probation: just as a general gives another opportunity to the troops, who in some evil moment have shown a want of spirit, to retrieve their honor. Now, if it be allowable to assume that this, or some similar idea, or some tradition of the kind, had an influence on and gave rise to the doctrine of the pre-existence of men, which is so generally diffused among the Hindoos, and which was also held by the Platonists, and even Christian Platonists, of the first centuries, we can then conceive how this otherwise so arbitrary assumption and groundless hypothesis could have arisen. Groundless, however, it may well be named, not only because no cause or explanation of it is adduced, but as being agreeable neither to the nature of the soul nor to the constitution of things; so that, regarded even in this light, it must be looked upon as a singular instance, and consequently as an exception from the laws of nature and as a miraculous intervention of divine power. But a mere pre-existence of spirits would, however, be no true pre-existence in the sense of the Hindoo theology, or of the Platonists, since, by its union with and by the accession of a soul, it becomes a wholly different and quite a new being. Moreover, in this hypothesis, as it is further worked out in the Hindoo and Platonic systems, the whole character and true destination of human life is entirely misunderstood, inasmuch as it is represented as a place and period of punishment; whereas, rightly conceived, and even philosophically contemplated, it appears rather as a battle-place, and the time of discipline and preparation for eternity. It is the problem and vocation of philosophy not merely to set forth the truth clearly and simply, but also, whenever it can be done incidentally and easily, to account for and explain great and remarkable errors, especially such as were prevalent among the earliest nations and ages. Now, among those errors which are most remarkable in ancient history, this of the Hindoos and Platonists holds in my eyes a very prominent place. But philosophically to explain an error, means not to reject it at once as absurd and undeserving of notice, but requires rather that we should first of all really understand it, _i.e._, that we should study it, and, to a certain degree, enter into its spirit, and seek to discover its best significance, or, in other words, that interpretation which is nearest to the truth, and then in conclusion accurately to determine the point where error begins and truth is violated.
