Context

“Haec vident omnes.' Pro Sext. sec. 42.] Whether such a condition of human nature could ever exist, or if it did, could continue so long as to merit the appellation of a STATE, may justly be doubted. Men are necessarily born in a family-society, at least; and are trained up by their parents to some rule of conduct and behaviour. But this must be admitted, that, if such a state of mutual war and violence was ever real, the suspension of all laws of justice, from their absolute inutility, is a necessary and infallible consequence.” source
