For example, take a number of children of one family, of one place, of one school, instructed by one teacher, reared on the same food, in the same climate, with the same clothing, and studying the same lessons—it is certain that among these children some will be clever in the sciences, some will be of average ability, and some dull. Hence it is clear that in the original nature there exists a difference of degree and varieties of worthiness and capacity. This difference does not imply good or evil but is simply a difference of degree. One has the highest degree, another the medium degree, and another the lowest degree. So man exists; the animal, the plant and the mineral exist also—but the degrees of these four existences vary. What a difference between the existence of man and of the animal! Yet both are existences. It is evident that in existence there are differences of degrees. The variety of inherited qualities comes from strength and weakness of constitution—that is to say, when the two parents are weak, the children will be weak; if they are strong, the children will be robust. In the same way, purity of blood has a great effect; for the pure germ is like the superior stock which exists in plants and animals. For example, you see that children born from a weak and feeble father and mother will naturally have a feeble constitution and weak nerves; they will be afflicted and will have neither patience, nor endurance, nor resolution, nor perseverance, and will be hasty; for the children inherit the weakness and debility of their parents. Besides this, an especial blessing is conferred on some families and some generations. Thus it is an especial blessing that from among the descendants of Abraham should have come all the Prophets of the children of Israel. This is a blessing that God has granted to this descent: to Moses from his father and mother, to Christ from his mother’s line; also to Muḥammad and the the Báb, and to all the Prophets and the Holy Manifestations of Israel. The Blessed Beauty(7) is also a lineal descendant of Abraham, for Abraham had other sons besides Ishmael and Isaac who in those days migrated to the lands of Persia and Afghanistan, and the Blessed Beauty is one of their descendants. Hence it is evident that inherited character also exists, and to such a degree that if the characters are not in conformity with their origin, although they belong physically to that lineage, spiritually they are not considered members of the family, like Canaan,(8) who is not reckoned as being of the race of Noah.
