" They tell us that suicide is the greatest piece of cowardice; that only a madman could be guilty of it; and other insipidities of the same kind; or else they make the nonsensical remark that suicide is wrong; when it is quite obvious that there is nothing in the world to which every man has a more unassailable title than to his own life and person. "
