Man, no doubt, owes many other duties to his fellow men; such as to feed the hungry, clothe the naked, shelter the homeless, care for the sick, protect the defenceless, assist the weak, and enlighten the ignorant. But these are simply duties, of which each man must be his own judge, in each particular case, as to whether, and how, and how far, he can, or will, perform them. But of his duty—that is, of his duty to live honestly towards his fellow men—his fellow men not only judge, but, for their own protection, judge. And, if need be, they may rightfully him to perform it. They may do this, acting singly, or in concert. They may do it on the instant, as the necessity arises, or deliberately and systematically, if they prefer to do so, and the exigency will admit of it.
