Some Ans. Questions 1908 by -'Abdu'l-Bahá- 1 Para

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 (212:4)
