 In this work, Posidonius detailed his theory of the effect on a people’s character by the climate, which included his representation of the "geography of the races".This theory was not solely scientific, but also had political implications—his Roman readers were informed that the climatic central position of Italy was an essential condition of the Roman destiny to dominate the world.As a Stoic, he did not, however, make a fundamental distinction between the civilized Romans as masters of the world and the less civilized peoples.
