139. Why are there both primitive and civilized people?
Apart from the preexistence of the soul, this question would be insolvable, unless we were to believe that God created primitive and civilized souls, which would be a denial of his justice. Furthermore, reason refuses to believe that, after death, the soul of the primitive either remains forever in its little- evolved state or that it is in the same position as the soul of the enlightened individual.
If one accepts the idea that there is one starting point for all souls — the only doctrine compatible with God's justice - the simultaneous presence of primitivism and civilization is a material fact that demonstrates the progress that some have achieved and that others are capable of achieving. The primitive's soul thus will attain the level of the civilized soul with time. However, since primitives die every day, their souls cannot attain such a level except through subsequent incarnations more and more perfected and suitable for their advancement, and after going through all the intermediary levels between the two extremes.
