ÎV.] WHAT HISTORY IS BEST WORTH'READING? But here we come upon another primary question, Is all History equally valuable ? You may say to me, we have accepted your assertion that no knowledge is useless, except by the fault of the person who possesses it ; but it does not follow that all is equally useful or equally valuable in itself. What history is the best worth studying for its own sake?
