(75) Why whoever should slay Cain should be liable to bear a sevenfold punishment? (Genesis 4:15). As our soul consists of eight portions, being accustomed to be divided in its rational and irrational individuality into seven subordinate parts, namely into the five outward senses, and the instrument of vice, and the faculty of generation; those seven parts exist among the causes of wickedness and evil, on which account they likewise fall under judgment; but the death of the principal and dominant portion of man, namely of the mind, is principally the wickedness which exists in it. Whoever therefore slays the mind, mingling in it folly, and insensibility, instead of sense, will cause dissolution also of the seven irrational parts; since, just as the principal and leading part had a portion from virtue, in the same manner likewise are its subject divisions composed.
