"if I believed that the choice lay between a sacrifice of the completest order of biography and that of the inviolability of private epistolary correspondence, I could not hesitate for a moment. I would keep the old and precious privacy,-the inestimable right of every one who has a friend and can write to him, - I would keep our written confidence from being made biographical material, as anxiously as I would keep our spoken conversation from being noted down for the good of society."
