George Shiras, Jr.,
New England Railroad Company v…
“ If he has done all that reasonable care requires to inquire into the competency of his servant, is any neglect imputable to him? No human inquiry, no possible precaution, is sufficient to absolutely determine in advance whether a party under certain exigencies will or will not do a negligent act. So it is not possible for the master, take whatsoever pains he may, to secure employees who will never be guilty of any negligence. Indeed, is there any man who does not sometimes do a negligent act? ”
