Then comes the opposite extreme--they are, like ourselves, the sons of Adam, and must therefore, have like passions and wants and feelings and tempers in all respects. This, we deny, and appeal to the knowledge of all who know. But their authority will be disputed, and their testimony falsified, unless we can devise something to show how a difference might and should have been brought about. Our theory is a short one. It was the will of God it should be so. But the means--how was this effected? We will give the answer to any one who will develop the causes which might and should have blackened the negro's skin and crisped his hair into wool. Until that is done, we shall take leave to speak, as of things _in esse_, of a degree of loyal devotion on the part of the slave to which the white man's heart is a stranger, and of the master's reciprocal feeling of parental attachment to his humble dependant, equally incomprehensible to him who drives a bargain with the cook who prepares his food, the servant who waits at his table, and the nurse who doses over his sick bed. That these sentiments in the breast of the negro and his master, are stronger than they would be under like circumstances between individuals of the white race, we believe. That they belong to the class of feelings "by which the heart is made better," we know. How come they? They have their rise in the relation between the infant and the nurse. They are cultivated between him and his foster brother. They are cherished by the parents of both. They are fostered by the habit of affording protection and favors to the younger offspring of the same nurse. They grow by the habitual use of the word "my," used as the language of affectionate appropriation, long before any idea of value mixes with it. It is a term of endearment. That is an easy transition by which he who is taught to call the little negro "his," in this sense and _because he loves him_, shall love him _because he is his_. The idea is not new, that our habits and affections are reciprocally cause and effect of each other.
