" First of all, you have heard me talk of Logres. It was the old name for this country, thousands of years ago; in the old days when the struggle between good and evil was more bitter and open than it is now. That struggle goes on all round us all the time, like two armies fighting. And sometimes one of them seems to be winning and sometimes the other, but neither has ever triumphed altogether. Nor ever will,” he added softly to himself, “for there is something of each in every man. "
