separate off from the rest the Friendship of Kindred, and that of Companions: whereas those of men of the same city, or tribe, or crew, and all such, are more peculiarly, it would seem, based upon Communion, inasmuch as they plainly exist in right of some agreement expressed or implied: among these one may rank also the Friendship of Hospitality.
The Friendship of Kindred is likewise of many kinds, and appears in all its varieties to depend on the Parental: parents, I mean, love their children as being a part of themselves, children love their parents as being themselves somewhat derived from them. But parents know their offspring more than these know that they are from the parents, and the source is more closely bound to that which is produced than that which is produced is to that which formed it: of course, whatever is derived from one's self is proper to that from which it is so derived (as, for instance, a tooth or a hair, or any other thing whatever to him that has it): but the source to it is in no degree proper, or in an inferior degree at least.
Then again the greater length of time comes in: the parents love their offspring from the first moment of their being, but their offspring them only after a lapse of time when they have attained intelligence or instinct. These considerations serve also to show why mothers have greater strength of affection than fathers.
Now parents love their children as themselves (since what is derived from themselves becomes a kind of other Self by the fact of separation), but children their parents as being sprung from them.[1] And brothers love one another from being sprung from the same; that is, their sameness with the common stock creates a sameness with one another; whence come the phrases, “same blood,” “root,” and so on. In fact they are the same, in a sense, even in the separate distinct individuals.
Then again the being brought up together, and the nearness of age, are a great help towards Friendship, for a man likes one of his own age and persons who are used to one
