Most of the inventions of men are subject to change. They depend upon humour and caprice. They have a vogue for a time, and then sink into oblivion. It may, perhaps, be apprehended, that if justice were allow'd to be a human invention, it must be plac'd on the same footing. But the cases are widely different.
