Stephen Johnson Field,
Chicago St. Railway Company v. Ross…
“ We have never known parties more willing to subject themselves to dangers of life or limb because, if losing the one, or suffering in the other, damages could be recovered by their representatives or themselves for the loss or injury. The dread of personal injury has always proved sufficient to bring into exercise the vigilance and activity of the servant. But, however this may be, it is indispensable to the employer's exemption from liability to his servant for the consequences of risks thus incurred that he should himself be free from negligence. ”
