140. Would it be possible, according to some people's way of thinking, that the soul incarnates only once but then goes on to accomplish further progress in the spirit state or in other realms?
This proposition would be acceptable if on the earth there were only people of the same moral and intellectual level, in which case we could say that the earth is meant for only one specific level; the exact opposite seems obvious, however. In fact, it would be incomprehensible that primitives could not become civilized on earth, since there are many advanced souls incarnated, on the same globe. From this we must conclude that the possibility for the plurality of earthly existences results from the very examples we have right before our eyes. If it were otherwise, we would have to explain: First, why would only earth have the monopoly on incarnation? Second, if such a monopoly were a fact, then why are there souls incarnated at every level of advancement?
