Those whose hearts never open to the feelings of humanity, should, we think, be shut out in the same manner, from the affections of all their fellow-creatures, and be allowed to live in the midst of society, as in a great desert where there is nobody to care for them, or to inquire after them.

Context

“We may often fulfil all the rules of justice by sitting still and doing nothing. As every man doth, so shall it be done to him, and retaliation seems to be the great law which is dictated to us by Nature. 4 Beneficence and generosity we think due to the generous and beneficent. Those whose hearts never open to the feelings of humanity, should, we think, be shut out in the same manner, from the affections of all their fellow-creatures, and be allowed to live in the midst of society, as in a great desert where there is nobody to care for them, or to inquire after them. The violator of the laws of justice ought to be made to feel himself that evil which he has done to another; and since no regard to the sufferings of his brethren is capable of restraining him, he ought to be overawed by the fear of his own.” source
