A branch cut off from its adjacent branch must necessarily be severed from the whole tree. Even so a man, parted from any fellow-man, has fallen away from the whole social community. Now a branch is cut off by some external agency; but a man by his own action separates himself from his neighbour—by hatred and aversion, unaware that he has thus torn himself away from the universal polity. Yet there is always given us the good gift of Zeus, who founded the great community, whereby it is in our power to be reingrafted on our kind, and to become once more, natural parts completing the whole. Yet the frequent happening of such separations, makes the reunion and restoration of the separated member more and more difficult. And in general a branch which has grown from the first upon a tree, and remained a living part of it, is not like one which has been cut and reingrafted; as the gardeners would say, they are of the same growth but of different persuasion.
