Our boys were astonished at the detailed information the Martians had on our earth life. One said that he had never clearly thought through its economic ills. He had merely accepted them. Although he had heard and studied many of these points, they are beginning to now take on a new significance. Another remarked that the observers seem to be more impressed and are more retentive to what takes place, than those who are within the actual performance of the scenes of our life's functions. Sun-Rank Banard said, "Now let's go back and continue the lecture. "Nature on your earth has destined and caused man to come into existence, and has provided him with parents to protect him during his helpless infancy and childhood. During his growth, development, and maturity, it endowed him with a mentality higher than that of other animals. But in spite of his intelligence, he is often more cruel than predatory jungle beasts, especially to his fellow men. "Creation is prolific even prodigal in its overabundance of production for your necessities and can produce and supply the needs of a population more than twice your number, providing you all will work; but many of you, for a life of ease, use this God-given intelligence especially for acquisition, storing and hoarding as a means of power over your fellow man. "During the Stone Age, your each tribe lived together in caves adjoining each other for protection, primitively tilling the soil, and grazing your cattle around your habitations. "It was then the survival of brute force. The bully domineered and became the leader of his tribe, acquiring for himself the most wives and food and the best shelter. The next best he bestowed upon his gang. "For defensive and offensive weapons against predatory animals and tribes, you used stones and stone axes. Brute force gradually lost its power when the more progressive one of the tribe became adept and dexterous with his stone throwing sling, his lance, and his bows and arrows. He then succeeded to the leadership. "As your numbers increased, you expanded your land holdings. This continued from generation to generation; from squatters you graduated according to your own laws of possession until the time came when you were encroaching on the lands of your neighboring tribes, starting your process of forceful aggression and acquisition. With the Iron Age started the evolution of your civilization, with sharp iron-pointed lances, arrows, and axes, leading to the barbarous Middle Ages. "Laws of property ownership, and barter of land, slaves, cattle, furs, clothes, utensils, ornaments, food, and offensive and defensive weapons marked the beginning of this era. In its constant evolution, property ownership law was continually and mercilessly improved according to your standards, with the utter enslavement of weaker tribes, and races who were a good source for procuring slaves and extracting tribute.
